What automatic release load switch mean? Refers to the situation encountered can quickly break the circuit some load switch operating mechanism is spring energy storage, load switch acceleration mechanism Xi'an instantaneous release, instant-on and breaking the double-break contact structure. Independent of the speed of the operating handle, greatly increasing the electrical performance and mechanical properties. Mainly said spring energy storage capacity, can greatly reduce the manual force. 1 load switch is with load off a self-extinguishing function but no arc chute structure to its breaking capacity is very small and limited 2 isolation switch is generally not with load off there can be breaking the load isolation switch only structure the load switch is relatively simpler 3 different load switch and isolation switch off point can form a clear majority of the circuit breaker does not have a small number of isolation circuit breaker with isolation isolation switch 4 does not have the protection of the protection usually load switch plus fuse Protection only 5 quick break and overcurrent circuit breaker breaking capacity in the manufacturing process can be done in a very high increase mainly rely on the current transformer with a secondary device may have a short-circuit protection overload protection leakage protection Shijiazhuang load switch, Xi'an high load switch provided by Xian Xian Huayi power plant.
