Original product description
. . Voltage Level Medium Voltage Installation Fixed Structure Cabinet Current AC Transport Package Wooden Case Specification IEC, GB, CE Trademark ROOQ/Neutral/OEM Origin China HS Code Summary Rooq's ring main units (RMU) can be adapted to meet all Medium Voltage power distribution needs,up to 24 kV.
The RM6 is a compact unit combining all MV functional units to enable connection, supply and protection of transformers on an open ring or radial network: * by a fuse-switch combination, up to 2000 kVA * by a circuit breaker with protection unit, up to 8000 kVA.
The switchgear and busbars are enclosed in a gas-tight chamber, fi lled with SF6 and sealed for life. Operating a distribution network sometimes requires switching oints in addition to the HV/MV substations, in order to limit the effect of a fault on the network.
The RM6 offers a choice of solutions to make 2, 3 or 4 directional connections: * with line protection by 630 A circuit breakers * with network switching by switch-disconnectors * with integrated power supply ns for indoor switchgears IEC 62271-1 (common specifi cations for high voltage switchgear and controlgear) Ambient temperature: class -25°C indoor Altitude : lower than or equal to 2000 m IEC (A.C.
metal enclosed switchgear and controlgear for rated voltage above 1 kV and up to and including 52 kV) Switch-disconnectors IEC (high voltage switches for rated voltage above 1 kV and less than 52 kV) Circuit breakers: 200 A feeder or 630 A line protection IEC (high voltage alternating current circuit breakers) Other applicable standards * Switch-fuse combinations: IEC : alternating current switch-fuse combination * Earthing switch: IEC : alternating current disconnectors and earthing switches * Electrical relays: IEC 60255.
Features 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 or to the transformer * a low voltage cabinet * 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 defi nition of a "sealed pressure system" laid down in the IEC ecommendations. The switch-disconnector and the earthing switch offer the operator all necessary usage guarantees: Tightness The enclosure is filled with SF6 at a 0.2 bar gauge pressure.
It is sealed for life after filling. Its tightness, which is systematically checked at the factory, gives the switchgear an expected lifetime of 30 years. No maintenance of live parts is necessary with the RM6 breaking. Switch-disconnector Electrical arc extinction is obtained using the SF6 puffer technique.
Circuit breaker Electrical arc extinction is obtained using the rotating arc technique plus SF6 auto-expansion, allowing breaking of all currents up to the short-circuit current. . As per IEC /BSEN 60076 standards these are set in accordance with the highest voltage for the material, being the level immedia 50.
