2 Description ield of application and utilisation range Description The Rollarc three-pole indoor contactor uses sulphur hexafluoride (S) gas for insulation and circuitbreaking. ircuit-breaking is based on the rotating arc principle. The basic version is made up of three pole units installed in the same insulating enclosure. The part of the enclosure containing the active parts of the poles is filled with S gas at a gauge pressure of.5 bars. There are two types of Rollarc contactors: c the R400 with magnetic holding c the R400D with mechanical latching. ield of application Protection and control of: c MV motors, c capacitor banks and power transformers.

3 Installation type The Rollarc R400 and R400D contactors are available in three versions: Basic version: ontactor alone, without the cradle. ixed version: The contactor with the control auxiliaries is mounted on a fixed cradle. Withdrawable version: The contactor with the control auxiliaries is mounted on a withdrawable cradle. ixed and withdrawable versions may be equipped with fuses when the short-circuit current is greater than the contactor rating. The fuses used are of the indoor usarc type with strikers that actuate the contactor opening mechanism. R400 / R400D Rollarc contactor 5
4 Description of the basic version Enclosure The epoxy resin enclosure ensures: c high mechanical strength enabling use as a support for the active parts and resistance to electromechanical stress. c excellent dielectric strength due to the nature of the material and the design. c a very reliable seal (sealed pressure system in compliance with standard IE 005, 987 edition, appendix EE). The filling pressure remains constant throughout the life of the contactor. Active parts and operating mechanism The essential parts include the: c arc interruption device, c insulating rod which actuates the mobile contacts and the corresponding fixed terminal. These parts are housed in an enclosure which is sealed for life and are thus totally insensitive to the environment. The resulting elimination of corrosion increases the reliability of the device. Electromagnetic coils ROLLAR is actuated by electromagnetic coils that ensure closing and hold the device in the closed position. coil Auxiliary contacts The auxiliary switch subassemblies are always mounted on the enclosure. Mechanical latching The R400D is actuated by electromagnetic coils that ensure closing of the device and has a mechanical latching device which holds the contactor in the closed position without a continuous power supply. A release is used to free the latching mechanism. Mechanical latching device Description of operation: see page 9 R400 / R400D Rollarc contactor

Using the permanent current value Ip, figure can be used to determine the maximum duration of Toc along line. The time required for cooling Tc to ensure that the equilibrium temperature is not exceeded may be determined using figure. Example: a Rollarc contactor with a permanent operating current lp = 40A can withstand a temporary overload of 400A for seconds. The cooling time Tc is: v 5 minutes if the circuit is open v 8 minutes if a 0A current flows through the contactor v 48 minutes if a 00A current again flows through the contactor. c yclical overcurrent the fourth parameter (see line between figures and ) can be determined when three of the four below are known: v Ioc overcurrent v Toc duration of overcurrent v Ic cooling current v Tc duration of cooling Example: Ioc 00A for 0 seconds Tc 00A for minutes Tr 50 min 00 min 0 min 40 min 5 min 5 min 0 min 7 min 5 min min min,5 min min 50 s 40 s 0 s 0 s ig.

14 S gas properties and Rollarc technique Advantages of Rollarc S The Rollarc rotating arc contactor is a modern device with enhanced cooling of the arc by forced convection leading to the following advantages: Long life This results from: c high product reliability, c very low wear of the active parts which require no maintenance, c the excellent sealing of the enclosure, eliminating the need for subsequent filling. Mechanical endurance The operating energy is reduced because arc rotation is directly created by the current to be interrupted. The Rollarc contactor can do operations in R400 version and operations in R400D version. Sulphur hexafluoride (S) gas properties S is a non-inflammable very stable, non- toxic gas, five times heavier than air. Its dielectric strength is much higher than that of air at atmospheric pressure. Gas for interruption S is "the" arc-interruption gas, combining the best properties: c high capacity for carrying away the heat produced by the arc. The latter is rapidly cooled by convection during the arcing period. c high radial thermal conduction and high electron capturing capacity. When the current passes through zero, the arc is extinguished by the combination of two phenomena: v S permits rapid heat exchange from the center of the arc toward the exterior. v fluorine atoms, which are highly electronegative, act as veritable "traps" for electrons. Since it is electrons which are mainly responsible for electric conduction in the gas, the gap between the contacts recovers its initial dielectric strength through this electron capture phenomenon at zero current. c the decomposition of the S molecule is reversible. The same mass of gas is therefore always available, making the device self-sustained throughout its operating life. Electrical endurance The long life of the Rollarc is due to the negligible degeneration of the gas and to low wear of the contacts. The energy dissipated in the arc is low due to: c the intrinsic properties of the gas, c the short length of the arc, c the very short arcing time. Wear of the arcing contacts can be checked without opening the poles. The unit is capable of breaking all load and short-circuit currents, even in the case of frequent operation. With very high breaking capacity for a contactor, the Rollarc can be used in a fuse-contactor assembly capable of protecting any circuit against all types of faults including overloads. Low switching surges The intrinsic properties of the gas and the soft break resulting from this technique means that switching surges are very low. oncerning motor start-up, the unit is free from multiple prestrike and restrike phenomena which could damage the winding insulation. Operating safety The Rollarc contactor operates at a low relative pressure of.5 bars. ontinuous monitoring of the contactor pressure (optional) A pressure switch actuates a contact in the event of an accidental drop in the pressure of the S gas in the Rollarc unit. Insensitivity to external conditions The Rollarc pole unit provides a totally gas-insulated system. It is a hermetically sealed enclosure filled with S gas and housing the essential parts. Rollarc is particularly suited to polluted environments such as mines, cement works, etc. R400 / R400D Rollarc contactor
15 The rotating arc technique The rotating arc principle The exceptional characteristics of S gas are used to extinguish the electrical arc. ooling is enhanced by the relative movement between the arc and the gas. In the rotating arc technique, the arc is set in motion between two circular arcing contacts (see figure opposite). When the main contacts separate, the current to be interrupted flows through a solenoid, thus creating an electromagnetic field B. When the arcing contacts separate, the arc appears between them. The arc is made to rotate between the two circular arcing contacts by force, the combined result of the electromagnetic field and the current. orce is directly proportional to the square of the current to be interrupted. This breaking technique therefore automatically adapts to the current to be interrupted. When the current is high, the speed of rotation is high (speed of sound) and cooling is intense. Just before reaching zero current, the speed is still sufficient to make the arc rotate and thus contribute to the recovery of dielectric strength at zero current. Wear of the arcing contacts is very low. When the current is low, the speed of rotation is also low. This leads to very soft breaking of the arc without surges, comparable to the widely appreciated performances of the air breaking technique. I I B R400 / R400D Rollarc contactor 7
16 Soft breaking Breaking of inductive or capacitive currents The Rollarc contactor does not generate voltage surges. On some switchgear such surges occur during the breaking of low inductive or capacitive currents and can damage the insulation of connected devices. With the rotating arc technique, the rotation speed of the arc is low for low currents and breaking is soft under all conditions. c current chopping: (arc interruption before zero current) the chopping current is always less than A, i.e. the voltage surge is very low for the load. c multiple prestrikes and restrikes Other phenomena exist that are much more dangerous to the load than the voltage surges resulting from current chopping. Such phenomena occur if the device tries to break high frequency currents. High frequency currents appear when there is a dielectric breakdown (opening of contacts is too close to zero current) and produce high frequency waves that are very dangerous for motor insulation. Given the relatively slow dielectric regeneration between its arcing contacts, the Rollarc contactor avoids breaking high frequency currents and multiple prestrike and restrike phenomena are prevented. The Rollarc is thus the perfect motor control contactor. It provides the user and the network with total security without requiring additional accessories such as surge arresters or R systems.

Rollarc 400 is a magnetic device that uses the rotating arc technique to interrupt the current. c at the beginning of an opening cycle, the main contacts and the arcing contacts are closed (fig.). c isolation of the main circuit is achieved by the separation of the main contacts (fig. ). The arcing contacts are still closed. The current flows through the coil, the arcing contacts and the flexible connector. c the arcing contacts open shortly after the main contacts. The resulting arc is made to rotate between the two circular runners of the arcing contacts by the electromagnetic field produced by the coil, the force of which depends on the current to be interrupted (fig. ). By design and due to phase shift between the current and the electromagnetic field, this force is still significant at zero current. c at zero current, the gap between the contacts recovers its initial dielectric strength thanks to the inherent qualities of S gas (fig. 4). fig. fig. 4 R400 / R400D Rollarc contactor 9
18 use-contactor assembly Utilisation guide use-contactor combinations Principle The contactor switches the load on and off during normal operation or an overload. The fuse ensures correct interruption of short-circuit currents according to the network short-circuit level. A "fuse-blown" device causes contactor opening. Economic advantages or a short-circuit level of 500 MVA, or of 50 ka at kv, the saving in switchgear costs is more than 50 % compared to a circuit breaker solution.
