Indoor Vacuum Circuit Breaker for Medium Voltage Switchgear Insulating Cylinder Structure VHE-12

  VHE-12 vacuum circuit breaker is an indoor power distribution device with a rated voltage of 12kV and a50Hz three-phase AC system. lt is a new product that developed by our company independently. We have theintellectual property rights. The product can be compatible with the V'S1.VD4 and so on.In the field of medium voltage, Especially 12 kV, Vacuum circuit breaker has been a mainstream productThe briliant achievement of vacuum circuit breaker can't be separated with the progress of vacuum circuilbreaker technology inseparable. The technology of embedded poles is the embodiment of the great progress ofvacuum circuit breaker. Vacuum circuit breaker insulation has experienced ar insulation- composite insulation -solid insulation, lt has formed three generations of vacuum circuit breaker, in the first generation-air insulation,The live part all exposed in air, its insulation level changes with the air humidity, Dust and the collision of the transport process , And easy to be infuenced by small animals and other foreign bodies. in the secondgeneration- composite insulation, The arcing chamber protected by epoxy resin sleeve. But the sleeve doesnot wrap the high-voltage electric parts wholly, lt would be affected by dust, Moisture, insects and so on.The third generation of insulation is embedded pole, By the APG process, Using epoxy resin to seal the wholearc extinguish chamber and the upper and lower outlet. To do this, Not only reduce the arcing chamber sizeand also completely unaffected by the exteral environment (dust, moisture, etc.) so that improve theweatherability, Epoxy resin at this time not only as a part of the main insulation, At also be a support for themechanical, The electric field distribution and the stress distribution is superior to the various shapes ofinsulating clapboard structure. Circuit breaker can be as a handcart type and fixed type, So cooperate withKYN28A,XGN2,GG-lAand convenient in oil-free transform.
