General presentation The very best of vacuum technology As a specialist in breaking technologies, Schneider Electric took naturally an interest in vacuum breaking techniques. A major R&D investment was made to develop and engineer Evolis, providing customers with the very best of vacuum Ceramic chamber Fixed contact Mobile contact Metal bellows Fig. 1: vacuum interrupter components Contact disk Make-up of a vacuum interrupter Vacuum interrupters basically have two electrical contacts (fig.1 ), one fixed and the other mobile, and a sealed enclosure. The latter enables a high level of vacuum...

General presentation The very best of vacuum technology (cont.) Schneider Electric's choices for Evolis combined with its industrial expertise provides customer with a highly reliable range of circuit breakers. These products are suitable for the most demanding conditions with the guarantee of full compliance with international standards. Evolis circuit breakers use AMF type vacuum interrupters. According to technical and economic optimization considerations, the axial magnetic ■ either by a coil outside of the interrupter (fig. 4), for rated voltages up to 17.5 kV ■ or by a coil integrated...

General presentation The very best of vacuum technology (cont.) Vacuum interrupter Industrial process expertise Systematic advanced control The main components of the circuit breaker, such as vacuum interrupter and operating mechanism, are produced by Schneider Electric. The vacuum interrupters are manufactured in an ultra-modern production unit in France. During manufacture, each circuit breaker is subjected to systematic advanced testing. Vacuum interrupter testing The level of vacuum in each interrupter is tested using the "magnetron discharge Using this sophisticated procedure,...

fixed version P2 stored energy operating mechanism 19

fixed version Evolis circuit breaker 17.5 kV fixed version The Evolis circuit breaker comprises a basic fixed version: ■ 3 poles integrated in a "sealed pressure system" type insulating enclosure. ■ a P2 type, spring-operated stored energy control mechanism, electrifiable. This gives the device an opening and closing speed that is independent of the operator, for both electrical and manual orders. It enables reclosing cycles ■ a front panel housing the manual operating mechanism and status indicators ■ upstream and downstream terminals for the power circuit connection ■ a terminal block for...

fixed version Main characteristics Electrical characteristics according to IEC 62271-100 Switching and protection of capacitor banks Evolis range circuit breakers are well suited for switching and protection of capacitor banks with installed power up to 2 Mvar installed in series with dampening reactor limiting inrush current to 2 kA. Evolis is also well suited for capacitor banks system with installed power higher than 2 Mvar in conjunction with anti-harmonic filtering system.

fixed version Connection tenninal The basic circuit breaker is equipped with drilled copper connection terminals, at the top and bottom of the breaking units. The connectors are fitted to the terminals using the corresponding bolts. Several variants are possible. Fixed connectors Horizontal connectors (H) Vertical connectors (V) Mixed connectors An adjustable connector enables the vertical distance to be increased to enable Extendable connectors Extendable connectors Mixed solution The insulation withstand values given in the performance table, do not take account With these connectors it...
