Product Description
HV vacuum circuit breaker VS1-12 series indoor AC HV vacuum circuit breaker is a three-phase AC 50Hz, rated voltage 12kV indoor HV switch equipment. Circuit breaker can bear frequent operation, has the ability of constant breaking and quick reclosing. Circuit breaker is front and back split charging structure, not only can be used as a fixed installation unit, but also can be assembled with chassis truck to form a handcart unit. It can be applied to a variety of loads and frequent-operation occasions and can be used in the industry and mining, enterprise, power plant and substation for control and protection of electrical installation. This product complies with the requirements of GB1984, IB3855, DL403 and IEC56. VS1 Series indoor HV vacuum circuit breaker arhitectural structure uses operation organization and front and back load extinguish arc room, the leading electricity loop feature is three-phase console model constructs. The arc room vertial installs n pipe type insulation muff, the insulation muff is poured by APG's technology, thus it especially resisted creeping discharge, This kind of design has reduced the dust greatly togethr on the surface of arc room, and not only can prevent the vacuum arc room from influence of outside, but aso can ensure to appear high prevent type even in the environment of damp and hot and serious filth environment.
