4 Introduction ABB indoor disconnectors, type OWD and OWIII are meant for closing and opening electrical circuits in currentless state. In open position, they make a visible and safe isolating gap in the circuit which cuts off the circuit from the side of the power supply. These disconnectors may work in horizontal and vertical position, in one, two and three pole versions depend of apparatus type. ABB offers wide range indoor disconnectors: Rated voltages:, kv Rated normal currents: A Rated short-time withstand current s up to 80 ka Indoor disconnectors OWD and OWIII

5 Indoor disconnectors type OWD. Operating conditions The disconnectors type OWD are to be installed indoors under the following conditions: a) the ambient temperature range for standard model N: 8 K (, +0 C) for tropical model T: 8 8K (, + C) b) the relative humidity for standard model N: 70% at 0K (+0 C) for tropical model T: 8% at 0K (+0 C) c) maximum altitude for installation (above sea level): 000 m.. Designations and switch types The structure of product marking is presented below: OWD 0 w. 0 / located on the permanent contacts with or screws (depending on the rated current). Disconnectors type OWD are adapted to operate in horizontal or vertical position. Disconnectors for rated voltages, kv and higher may be operated manually by means of the manual operating mechanisms (HE, NRWO-) or by means of motor operating devices type UEMC0A_ (mounted on the front panel of the cubicle), UEMC0K (mounted on the disconnector s base), pneumatic operating mechanism type NP8. Disconnectors for rated current, kv by means of the manual operating mechanism, motor drive type UEMC0A_ or an insulating stick. When driven by an insulating stick and UEMC0K they should be situated vertical only. Type Number of poles one two three Rated voltage 0, kv 0, kv 0 kv 0 kv Rated current w A (N) 0 A (T) w A (N) 000 A (T) w A (N) w A (N, T) Type of operating mechanism or pole distance (specified only for non-standard distances) with lever for coupling with manual operating mechanism NRWO or an isolating rod for, kv disconnectors, pneumatic operating mechanism type NP8 on the right hand side, pneumatic operating mechanism type NP8 on the left hand side, two pneumatic operating mechanisms type NP8, 00 pole distance 00 mm. Equipment Indoor disconnectors type OWD may be equipped with manual, motor, or pneumatic operating mechanism and an auxiliary switch. Manual and motor driven operating mechanisms do not form an integral part of the disconnector and are supplied to separate orders. The type of operating mechanism applied depends on the type of disconnector, in accordance with table (the table does not account for pneumatic operating mechanisms). Table Type of disconnector OWD0w.0, OWD0w.0 OWD0w.0, OWD0w.0 OWD0w.0, OWD0w.0 OWD0w.0 OWD0w.0, OWD0w.0 OWD0w.0, OWD0w.0 OWD0w.0, OWD0w.0 OWD0w.0, OWD0w.0 OWD0w.0, OWD0w.0 Type of operating mechanism HE, NRWO-, UEMC0 A_ or isolating rod HE, NRWO- UEMC0 A_ UEMC0 K_. Design and operation One, two and three pole disconnectors type OWD are the vertical break disconnectors. The base is a steel frame to which the operating mechanism is fixed. Bracketing insulators are fastened to the frame and are the mounting for the current circuit which consists of two fixed contacts and one moving contact on each pole. The moving contacts are connected to the shaft by means of insulating pull-rods. Pressing the moving contact to the fixed contact is solved in such a way that, at shorting currents, due to the effect of magnetic action upon the cover plate, the pressure increases. This allowed to obtain high rated values of peak current and shorting heat current. Two contact rails may be fixed to each terminal clamp A mechanism type NP8 is used as pneumatic operating mechanism, with rated pressure 0,, MPa, one or two drives are used, depending on the rated pressure and model of the disconnector in accordance with the table. If a disconnector is ordered with pneumatic operating mechanism or motor UEMC0K, it is coupled with the mechanism by the manufacturer and is an inseparable part of the complete supply.

Design and operation Disconnectors type OWII are the vertical break disconnectors. The disconnectors base is made as a welded steel frame. The frame together with the disconnector shaft and the limiters of the angle of rotation forms a non-dismountable unit. The base carries the insulators which support the main circuit consisting of two fixed contats and one moving contact in each pole. The moving contacts are connected with the disconnector shaft by means of insulating pull rods which transfer the rotation of the shaft to the moving contacts bringing them in sweep motion in the plane perpendicular to the disconnector base. The intrepole isolation is an air gap. In models with a smaller interpole scale, the air gap is further assisted by isolating plates. The disconnectors may be opened and closed by the following operating mechanisms: manual: type NRWO/... or HE, pneumatic, type NP9, motor, type UEMC0A_, insulating stick. The disconnectors, equipped with manual, motor or pneumatic operating mechanism, may operate in horizontal or vertical position (driven by insulating stick only in vertical position). The construction of disconnectors allows for the addition of earthing switches. Earthing switches may be located on pivot side (lower earthing switches) or on opening (upper earthing switches). At the base of the disconnector there is an earth terminal with Mx0 screw. Between the disconnector shaft and the earthing switch shaft, there is a mechanical interlocking ensuring the proper order of switching.. Equipment Disconnectors type OWIII are equipped with an operating lever set on the shaft, which can be moved every 0 within the limits of a full turn. This lever is for coupling with operating mechanism type NRWO/... and with a lever arm which is an extension of the operating lever, meant for driving the disconnector by means of an insulating stick. In the case of disconnectors with motor operating mechanism UEMC0A_ there is no lever. Instead, there is an assembly of bevel gear linking with the operating mechanism. The disconnectors may be equipped with an auxiliary switch (type PS- or PS-O) coupled with the apparatus, located on the end of the shaft opposite to the operating mechanism. Standard number of auxiliary switch contacts is (NO+NC).. Technical data The technical data of disconnectors are tabulated in the table on pages -.. Standards Disconnectors type OWII comply with the standards: IEC 7-:007, IEC 7-0: Spare parts The apparatus, for the duration of its technical lifetime, i.e. 000 operations, does not require spare parts. On the user s request, spare parts may be supplied for those damaged during random events, however, their replacement should be consulted with the manufacturer each time, and made by ABB service or by employees of other companies who have been trained by the manufacturer. 8.

PS- PS- auxiliary switch additional information on number of contacts is given in parentheses (; 0; 8; ) PSO PSO auxiliary switch additional information on number of contacts (; 0; 8; ). Construction and operating principle The NRW0... manual operating mechanism is a four-bar linkage with cranks and rocking levers. It contains a hand lever, arched pull rod, a double lever welded to the shaft terminated on one side with multinotches and two side plates, between which the entire kinematic configuration is located. Operation is possible by appropriate use of the four-bar linkage properties, which by setting the crank causes the rocking lever and the attached connecting lever to rotate. Rotation of this lever is transferred, by means of the pull rod, to the lever on the disconnector shaft. The hand lever has a knob at the top. The two side plates contain a sleeve for assembling the locking device. Fenders are also welded in order to limit deviation of the hand lever. The auxiliary switch is located on the bracket fixed to the upper edges of the side plates and is connected to the drive shaft by means of a special mechanism, which shifts the moving contacts in the final stages of shaft movement..

22 Motor operating device type UEMC0_. General The UEMC 0 A_, and UEMC 0 B_ motor operating devices are intended for indoor mounting on medium voltage disconnectors and earthing switches. Operation can be performed both electrically or by means of the manual operating lever. Operating time is about...8 s depending on the type of device and loading conditions.. Standards The motor operating device complies with IEC (98) VDE 00 motor voltage test Rys Power unit. Limit switch. Guide pin. Coupling ring. Locking catch. Motor 7. Terminal block 8. Control push button 9. M.c.b. 0. Contactor. Lever. Nut. Construction Power is transfered from the motor through a gear wheel and threaded shaft to the operating axel. The direction of operation for open and close control can be reversed by changing the motor s direction of rotation. The threaded shaft gear is assembled from a round stainless steel shaft and one or two bronze nuts. The shaft is selflocking which means that the operating device cannot be rotated with a force from the operating axel. This also applies if the operating device is in the central position. The nuts transfer the power through the specially formed lever to the operating axel. The lever is formed so that it can be locked in the extream position. By disengaging the coupling ring, manual operation can be performed by means of the control lever. Both the gear wheel and the threaded shaft are greased with low temperature grease which ensures correct operation in temperatures as low as 0 C... Mechanical locking The unit is fitted with a locking device which also includes a switch to prevent the motor from operating. The locking unit mechanically locks the operating device and is strong enough to withstand the driving force of the motor if the blocking switch S fails. The locking unit locks both the motor operating device and the manual operating device.. Electrical operation Motor operating device type UEMC 0 A_, B_ are fitted with a lower level of electrical components, and require a separate control unit, such as UEZJ or UEZJ.

34 NO type electromagnetic interlock. Features effective interlocking a disconnector control devices in off-voltage state, easy operation, easymounting on disconnector control unit, reliable, metal structure, metal parts protected by electroplating or made of stainless steel.. Applications The NO type electromagnetic interlock for indoor use is designed to interlock NRWO disconnector control devices in open or closed state, enabling a correct operating of such control devices in control and interlocking system of indoor switchgears. The NO type interlock, without voltage supply is always locked and its design makes it impossible to take lock back from control lever in a mechanical way without energizing the electromagnet coil.. Versions N0 0 Interlock type Rated voltage 0 V DC 7 V DC V DC 0 V DC 0 V DC 8 V DC V DC. Design and operation The NO type electromagnetic interlock consists of two main components.the mechanical part is made of a body closedwith cover. The spring-operated lock is placed in the body.the lock hole ends with nut, whereas the pull rod ends with ring handle. Pusher controlling a micro-switch, which switches in turn voltage fromterminals to the coil, is located in the upper part of the body.the micro-switch with terminals is placed under protective cover. The electromagnetic part consists of a plunger tightenedwith spring. Electromagnet coil is located in a housing fastened to the base. The base with bearing is mounted in the lower part of the interlock body. In case of the NRWO type apparatus interlock is fixed by means of two Mx0 screws. As a result of the interlock s mounting on the disconnector control, the lock is plunged in the hole of control lever, thus disabling its rotation, which in turn makes it impossible to operate the disconnector control device. As a result of pulling the ring handle with hand the pull rod moves along the lock axis, pushing the pusher upwards. The action in question switches the micro-switch and supplies at the same time the electromagnet coil. The coil magnetic field draws the plunger out from the lock. Further pulling of ring handle causes that the pull rod pulls the lock with it, which -in turn- drawing out from the disconnector control lever holemakes it possible to operate the disconnector control (pushing the lever in the limit positions, i.e. to closed and open positions). Leaving the control lever in intermediate position and releasing the interlock ring holder makes the electromagnet operate continuously till the control lever is pushed to limit position. After pushing control lever in position open or closed and after releasing Indoor disconnectors OWD and OWIII

35 the interlock ring holder all springs of interlock mechanism make interlock return automatically to the original state. The interlock design disables to operate disconnector control devices in the absence of interlock supply voltage coming from control and interlocking system of a switchgear, thus when the operation of disconnector control device is forbidden..
