The Schneider Electric's recycling procedure The Schneider Electric's recycling procedure forSF6 based products is subject to rigorous management, and allows each device to be traced through to its final destruction Schneider Electric is committed to a long term environmental approach. As part of this, the RM6 range has been designed to be environmentally friendly, notably in terms of the product's recycleability. The materials used, both conductors and insulators, are identified and easily At the end of its life, RM6can be processed, recycled and its materials recovered in conformity with the...

RM6 switchgear comprises 1 to 4 integrated, low dimension functional units. This self-contained, totally insulated unit comprises: ■ a stainless steel, gas-tight metal enclosure, sealed for life, which groups together the live parts, switch-disconnector, earthing switch, fuse switch or the circuit breaker ■ one to four cable compartments with interfaces for connection to the network ■ an electrical operating mechanism cabinet ■ a fuse chamber compartment for fused switch-disconnectors or fuse switches. The performance characteristics obtained by the RM6 meet the definition of a "sealed pressure...

Switch-disconnectors and circuit breakers have similar architecture: ■ a moving contact assembly with 3 stable positions (closed, open and earthed) moves vertically (see sketch). Its design makes simultaneous closing of the switch or circuit breaker and the earthing switch impossible. ■ the earthing switch has a short-circuit making capacity, as required ■ the RM6 combines both the isolating and interrupting function. ■ the earth collector has the correct dimensions for the network. ■ access to the cable compartment can be interlocked with the earthing switch and/ or the switch or circuit breaker. 3...

Operating safety Cable insulation test In order to test cable insulation or look for faults, it is possible to injecta direct current of up to 42 kVdc for 15 minutes through the cables via the RM6, without disconnecting the connecting devices. The earthing switch is closed and the moving earthing connection is opened in order to inject the voltage via the "earthing covers". This system, a built-in feature ofthe RM6, requires the use of injection fingers (supplied asan option). Voltage indicator lamps A device (supplied as an option) on all functional units makes it possible to check the presence...

RM6 Marine: benefits of the MV loop adapted to the boat The RM6 has the DNV type approval certificate for Marine applications. A MV loop configuration offers significant advantages: ■ main MV switchboard smaller (only two cells to feed a MV loop) ■ length of MV cables reduced (shortening average ratio > 30% for the configuration) ■ the maintainability and availability of the network are also improved. ■ a failed cable section on the MV loop can be disconnected ■ an automatic reconfiguration of the MV loop after a fault detection ■ If RM6 is equipped with special "filter" LRU (internal, arc Reduction...
