Use instead of the circuit breaker switch due to load and easy to use affordable and therefore the load switch is widely used in 10kV distribution network system in a reasonable load switch is mainly used for breaking and closing load current and high-voltage fuse load switch also can cooperate in the design Selection load switch for safety and reliable operation of the grid is of great significance. A load switch is possible with load off of a self-extinguishing function but no arc chute on the structure of its breaking capacity is very small and limited two isolation switch is generally not with load off there can be breaking the load isolation switch only structure and the load switch is relatively simpler three different load switch and isolating switch can form a clear majority of the circuit breaker off point does not have a small number of isolation breaker with isolation isolation switch 4 does not have the protection function is generally load switch plus fuse protection Protection only 5 quick break and overcurrent circuit breaker breaking capacity in the manufacturing process can be done mainly by increases in high current transformer with a secondary device may have short-circuit protection Overload protection leakage protection features such as load switch Wuhan Xiangfan Switches | Switches | Huayi electricity provided by Xian Huayi power plant.
