The original packaging material should be used for subsequent shipping and storage. Store the vacuum switch in a dry, dust-free, non-corrosive area. Ensure the vacuum switch is positioned to minimise the risk of mechanical damage particularly the insulator sheds. HNDLE WITH CRE. Do not attempt to move the switch unassisted The PS36 weighs approximately 105kg (230lb). Do not lift the switch using the insulators always move using the switch body. Ensure correct lifting technique is used at all times. Failure to follow correct handling procedures could result in personal injury and equipment damage. 4 BB PS36 Capacitor Vacuum Switch The switch is delivered affixed to the crate / pallet base with M12 hex head screws. It is strongly recommended that the switch is left on the pallet base during any movements, and that all movements be performed with a forklift or pallet jack/trolley.

5 7.0 Lifting the PS36 When lifting the switch, avoid any stress to the functional insulating parts (poles) and the terminal connections of the unit. When lifting the switch off the base pallet the integrated housing lifting holes should be used (Figure 2). This ensures the centre of gravity of the unit is maintained and prevents the switch from swinging around when off the ground. It is recommended that a jib or crane should be used when lifting the switch as shown in figure 2. Care should be taken to ensure that any ropes or slings used do not interfere with the switch insulator poles. Centre of gravity line Figure 2: Lifting the switch using the integrated lifting points Centre of gravity line Figure 3: Lifting the switch horizontally using the lifting brackets If the switch requires mounting either horizontally or vertically (ie base not on ground), purpose designed lifting brackets and associated fasteners can be supplied by BB (figure 3 and 4). The brackets are to be bolted to the body of the switch using 1 bolts in the surge arrester mounting holes. Once the switch is firmly in place using the base mounting holes/ brackets, the lifting brackets should be removed before energising the switch or putting into service. Further information on installation can be found in section 11. When lifting the switch using the supplied brackets, the centre of gravity is maintained through the axis lines shown. Figure 4: Lifting the switch vertically using the lifting brackets Care should be taken when lifting up the switch using the side lifting brackets. Lifting the switch too quickly could result in the switch tipping over and damaging the insulators. PS36 Capacitor Vacuum Switch BB 5

6 PS36 Capacitor Vacuum Switch 8.0 Description of operation The PS36 vacuum switch is a solid dielectric, gang operated 3-phase vacuum switch suitable for use in a wide range of industrial and distribution system applications. The switch utilizes BB s proven vacuum technology that is specifically designed for switching capacitor loads. Its design incorporates a fast acting solenoid mechanism, which provides force-travel characteristics ideal for vacuum switching. The solenoid mechanism also reduces the number of parts in the design and reduces the need for routine maintenance. The PS36 differs to the single interrupter design of lower voltage BB PS switches in that each phase is switched using a pair of vacuum interrupters connected in series. This is achieved by connecting together two switching poles with heavy duty bus connections. The current flow path for a particular phase is shown in figure 5. Each vacuum switch consists of: Six single pole vacuum switches with mechanical latching (separate open and close signals required for operation), depending on model ordered. mechanical position indicator signalling OPEN / CLOSED position state, while doubling as a lever to manually trip the switch. See figure 5. Various control voltage options. uxiliary limit switch contact outputs for switch position indication. Both heavy duty contacts and signal duty volt free contacts which monitor each pole are provided. Standard 10-pin panel mounted mil-spec connection plug Highly durable, corrosion resistant, grade 304 stainless steel tank housing Optional BB CQ900R Smart controller for manual or automatic switch / capacitor bank operation. unique characteristic of the PS36 switch is the two-stage closing operation. When a close signal is sent to the switch, the first interrupter of each phase will simultaneously close, followed 100ms later by the second interrupter of each phase simultaneously. Further information on the switch operation can be found in section 12. Each vacuum switch has insulators made of advanced hydrophobic cycloalaphatic epoxy (HCEP) resin. This is highly chip and crack resistant with insulating properties similar to silicone. The hydrophobic property lead to less surface wetting, provides better reliability and improves life expectancy. It is resistant to ultraviolet light while its high creepage characteristics ensure suitability in highly contaminated environments.

7 8.2 Capacitor bank application DNGER HIGH VOLTGE! The application engineering of the PS36 vacuum switch should only be performed by authorised The switches need a control signal (pulse) lasting a minimum of 1 second to fully operate the switch (open / close). personnel. The switch is suitable for a variety of applications including pole mounted capacitor banks and metal-enclosed capacitor banks. It is an outdoor device, which can also be applied to indoor solutions. It is highly recommended that the vacuum switch is protected under short-circuit conditions. Fuses and circuit breakers are typically used. For example, in pole mounted capacitor banks, expulsion drop-out fuses are typically connected upstream as means of protection. Figure 6 shows a typical connection diagram for a polemount capacitor bank. For specific installation recommendations or advice, please contact BB. 8.3 nti-condensation heater operation The vacuum switches can be switched using a variety of controls. Manual control (ie. push buttons) is the most basic form. utomatic controls using time, temperature, voltage, current, VR, power factor or a combination of the above (ie CQ900 Smart controller) can also be used. BB can provide the complete polemount solution through integration of its range of outdoor products. BB s product range also includes, but is not limited to power capacitors, controllers, control voltage transformers, surge arrestors and fuse cut-outs. Please contact BB for further information on related products and solutions. CONNECTION DIGRM SUPPLY SIDE The PS36 contains an integrated thermostat and heating device to prevent the occurrence and build up of condensation inside the switch housing. CT FUSES If the PS36 is installed outdoors it is a requirement that the anti-condensation heater power supply be connected. For indoor and metal enclosed applications, the heater connection is generally not required. The wiring configuration options of the PS36 allows for the heater to be run from an C power source regardless of whether the switch is being operated from an C or source. This prevents the potential to drain a power source when continual low temperature operation is called for. It is also common to connect the VT to its own drop out fuse so that control power is not lost in the case of a failed capacitor causing a fuse to blow. This is useful for troubleshooting purposes, and allows the control circuit (including the switch) to be tested without connecting the capacitor bank to the network. More information on control wiring can be found in section 12.

16 PS36 Capacitor Vacuum Switch 12.2 Controlling / operating the switch Operation of the PS36 switch requires a control signal of at least 1 second be applied for each TRIP (OPEN) and CLOSE operation. Signals are to be supplied between the active pin (open or close) and the neutral pin. The dual pole design of the PS36 switch requires a two-stage closing operation. This results in the highest restrike classification being achieved and excellent withstand capabilities. When a close signal is sent to the switch, the first interrupters The BB CQ900 series capacitor controller is ideal for control of the entire range of PS series vacuum switches. The CQ900L is a standalone automatic smart controller while the CQ900R is a fully featured remote controllable device utilizing DNP3.0 as the communications protocol. Other features include a 4-line LCD screen, user friendly interface, neutral current sensing, BB CapLink short range wireless communications, and intuitive programming software. Please contact your BB representative for more information. of each phase will close simultaneously, followed Due to the current draw from the switch during the 100ms later by the second interrupter of each phase OPEN / CLOSE operation (up to 30), it is recommended simultaneously. The resultant clunk clunk noise that no more than one PS36 switch be actuated heard during a PS36 closing operation is a unique simultaneously on the same supply. operating characteristic of the switch and is no cause It is recommended that a VT no smaller than 1.5KV be for concern. The electronics inside the switch ensure power is only drawn for the time required to actuate the switch (approx 100ms). Leaving the control signal permanently on to the switch (latched signal) has no detrimental effect on switch operation. The pin assignment for the neutral (B), close (C) and open (D) remains the same for each variant of the PS36 (Figure 16). n electronic manual or automatic controller is recommended for operating PS vacuum switches. The controller contacts should have a transient inrush rating of greater than 10 per switch (30 total). It is recommended that a controller operating a PS36 switch should contain a Slow Blow 10 to 12 amp switch fuse. used for controlling the PS36 (particularly for polemount operation). Using an undersized power supply can cause an instantaneous voltage drop during switching and prevent the switch from completing its operation. Continued operation under this condition can damage the switch s control circuit board leading to switch failure. Please contact BB for more information if unsure. Control Operation The rapid current draw that takes place when the switch operates requires that the power source be chosen carefully to match. If 48V control operation is required, please contact BB for application advice specific to 48V operation. It is recommended that a capacitor discharge power supply be utilised for 48V control applications. 16 BB PS36 Capacitor Vacuum Switch It is common that many UPS / inverter style power supplies will not be able to handle the high inrush currents required to drive the switch. Continued attempts to operate the switch with an underpowered supply can damage the switch controls. It is recommended that a high capacity battery pack be used if is the preferred operating voltage type.

17 Electrically held operation Electrically held / contactor type operation is NOT available with the PS36. Please contact BB if electrically held operation is a requirement for your application. uxiliary limit switch operation Each PS36 switch is fitted with internal limit switches to indicate the position of the switch HV contacts. The output from the volt-free contacts can be connected to a relay or control system to monitor the operation of the switch remotely. n example of the connections of each of these is shown in figure 16. N/O or N/C is based on whether the switch is in the open position. There are two types of limit switches in the PS36 a N/O and N/C (changeover) heavy duty contact, and lighter duty contacts which measure the position of each actuator pole individually with the outputs being connected in series. The following table outlines the ratings of each type: Limit switch output Rated current Rated current Given the internal limit switch is controlled by the C 125/250VC) (125V) movement of the solenoid within the switch, if Heavy duty Limit switch output B - ctuator physical force, welding of the HV contacts etc.) the limit switch may not give a true indication of the position of the HV contacts inside the vacuum interrupter. Heavy duty Limit switch output C the switch is damaged (due to excess wear, external The limit switch output should not be used as the sole indication of the status of the switch especially where live voltages and personnel are involved. Proper isolation and earthing procedures should always be used where live equipment is concerned to ensure a true visual break. PS36 Capacitor Vacuum Switch BB 17

18 PS36 Capacitor Vacuum Switch 12.3 Manual trip operation s with all models in the PS switch range, the PS36 has a combined manual trip lever / switch position indicator. The switch can be manually opened by pulling down on the manual trip lever, typically with a hook-stick. The manual trip lever requires approx 10kg (22lb) of force to open. Figure 17: Indicator lever arm in switch closed position. When the switch is in the closed position, the indicator lever arm will be sitting in the horizontal position (parallel to the base) (Figure 17). When tripped or open the lever will hang down approx 45deg from its closed position (Figure 18). Figure 18: Indicator lever arm in switch open position. (Label removed for clarity) The trip lever can only be used to open the switch. The switches internal mechanisms will not allow the switch to be closed manually using the indicator/trip lever. Trying to force the switch to close this way can result in damage to the switch. 18 BB PS36 Capacitor Vacuum Switch Excessive force used to manually trip the switch can pull the indicator lever out of its locating mechanism resulting in nonindication of switch operations. It can also stress or damage the lever, reducing its operational life. Where possible, it is better to use electrical control signals to operate the switch.

19 Manual trip lever with vertically / horizontally mounted switches When the switch is in its standard (upright) configuration the manual trip function is performed by pulling down on the manual trip lever. If the switch is mounted vertically or horizontally (as per figures 3 and 4) the manual trip lever can be mounted in a way that still allows manual tripping by pulling down on the lever. See figures 19 and 20. Figure 19: Indicator lever arm in closed position. To modify the position of the indicator lever: Remove the housing indicator lever label Loosen the lever fixing screw using a 5mm hex wrench / llen key, until the lever is able to move freely from its locating slot. Rotate the lever arm 90 degrees so that the lever is horizontal in the closed position. Take care to ensure the lever sits back in the locating slot. Place some loctite on the thread and re-tighten the M5 hex head screw Replace the housing indicator label. Figure 20: Indicator lever arm in open position. PS36 Capacitor Vacuum Switch BB 19

20 PS36 Capacitor Vacuum Switch 13.0 Operation testing and initial checks Before operation, the following inspections / tests should be performed: Insulators are free from damage and chips Tank housing is free from dents and obvious damage HV terminals are solidly fixed. Terminals do not twist with hand force Position indicator / manual trip lever is not jammed If in the closed position, pull down on the manual trip lever to open the switch manually Pre-installation Before connection of the HV conductors the following operation tests should be performed (test bench or workshop operation): Operate the switch using the electrical control signals. This can either be from an automatic capacitor controller, manual test box or custom source. Ensure that the position indicator lever transitions from the open to closed position with the appropriate signal. Ensure that when the close signal is sent that the double clunk noise characteristic of the dual interrupter operation is noted. It is recommended that a meter be used to confirm the continuity or open state across the terminals of each phase. If being monitored, check that the state of the limit switch contacts transitions with each operation as expected. The PS36 can only be closed using an electrical control signal. There is no manual close function Pre-energization DNGER HIGH VOLTGE!

Failure before the below steps to ensure a physical barrier between the to execute safe work practices can result in death, switch and the system. severe personal injury and equipment damage. Once installed (before HV is turned on) the following operation checks / tests should be performed: The switch mounting points are mechanically secure and the switch is solidly in place. The earth cable has been installed in the switches earth point. The control cable has been firmly screwed into place using the correct Mil-Spec mating connector. Electrical clearances between the switch and other apparatus is maintained. ll terminal connections are tight and fit for purpose. Operate the switch using the electrical control signals. This can either be from an automatic capacitor controller or manual test box. If available at this point it is best to use the control device (and power source) that will be controlling the switch when in general operation. 20 BB PS36 Capacitor Vacuum Switch Ensure that the position indicator lever transitions from the open to closed position with the appropriate signal. Ensure that when the close signal is sent that the double clunk noise characteristic of the dual interrupter operation is noted. If being monitored, check that the state of the limit switch contacts transitions with each operation as expected. The switch is now ready for service operation.

21 13.3 Service operation Ensure switch is in the OPEN position before replacing fuse links (upstream protection) back into service. Failure to do so can damage the capacitors, blow the fuses and trip upstream protection devices. The capacitor bank requires several minutes If not already done so, energise the high voltage lines as per your company s standard operating procedures. 5 minutes (S and IEEE) or 75V in 10 minutes (IEC): to discharge prior to, and between successive operations. If the waiting time is not specified on the capacitor unit rating plate, contact the manufacturer. Standard discharge levels are 50V in ssuming the minimum reclose block period has been satisfied, the switch can be operated with the capacitor bank online. The switch can now be left to operate as required via manual, automatic or remote means and in accordance with your company s procedures for safe capacitor bank control Maintenance DNGER HIGH VOLTGE! Ensure authorised personnel perform the maintenance of high voltage equipment in accordance with standard operating procedures. Failure to execute safe work practices can result in death, severe personal injury and equipment damage. The PS36 vacuum switch has been designed with a mechanical life of over 30,000 close-open operations without the need for routine maintenance. The switches do however require routine inspection to check for physical damage and to verify their operation. The frequency of inspection depends on the service conditions. The switches are designed for widely varying applications and climatic conditions and thus service intervals are best determined by the operator based on site conditions and operating experience.
