Classification and function of High Voltage Switchgear High Voltage Switchgear cabinet equipment for electrical power systems. The role of high voltage switchgear in the power system for power generation, transmission, distribution and power conversion process, make opening and closing, control and protection. High Voltage Switchgear unit within the main high voltage circuit breakers, high voltage isolation switch, high voltage load switch, high voltage operating agencies. Classification of High Voltage Switchgear many low voltage, such as through the circuit breaker can be mounted into withdrawable and fixed high voltage switchgear high voltage switchgear, or follow the cabinet structure of different manufacturers of low voltage switch cabinet, divided into open high voltage switchgear, metal-enclosed box-type high voltage switchgear, metal-enclosed high voltage switchgear and interval-type metal-enclosed high voltage switchgear and other armored. Indoor AC high voltage SF6 ring network switching equipment Usage RMU for three-phase AC 50Hz low voltage screen, the rated voltage of 12kV indoor power distribution equipment. Widely used in industrial and civil cable ring network and power supply end. Especially for small secondary distribution stations, opening and closing, the mining industry, urban residential areas, airports, railways, tunnels, high-rise buildings and other power systems for receiving and distributing electric energy. Features 1: AC high voltage SF6 ring network switching equipment indoors is a new generation of sulfur hexafluoride load switch as the main switch and the entire cabinet with air insulation for power distribution automation, both compact and extensible metal-enclosed switchgear. 2: RMU has a simple structure, flexible operation, reliable interlocking characteristics of a variety of different applications, different user requirements can provide a satisfactory technical solution. Latest sensor technology and the use of protective relays, coupled with advanced technical performance and lightweight flexible assembly program, can fully meet the changing market demands. 3: The main technical parameters Rated voltage 12 KV load combination of electrical switchgear cabinet 12 Rated frequency 50 Hz load combination electrical switchgear apparatus 50 A rated current load combination of electrical switchgear cabinet 125 630 rated short-circuit current 50 KA load combination of electrical switchgear Cabinet 80 back to the main road load resistance μΩ ≤400 combination of electrical switchgear cabinet ≤400 rated insulation level KV: 1min power frequency withstand voltage phase, relative to 42 fracture 48; lightning impulse withstand voltage phase, relative to 75 fracture 85 auxiliary circuit 1min power frequency withstand voltage KV load combination of electrical switchgear cabinets 2 2 South County voltage switch _ _ Xi promise of low voltage electrical and mechanical systems by learning Connaught Mechanical and Electrical Equipment Co., Ltd., Henan.
