Description

technical field

[0001] The invention relates to an intelligent control switch device for a power distribution system, in particular to an intelligent high-voltage electric switch device. Background technique

[0002] Usually, the switchgear used on the high-voltage side of the distribution transformer mostly adopts drop-out fuses. When the power transmission is to be stopped, it needs to be manually operated phase by phase according to the prescribed operating procedures. Therefore, it is troublesome to use, unsafe to operate, and extremely inefficient. In recent years, a remote control drop-out fuse has appeared on the market. Due to design defects, in practical applications, it is found that this remote control drop-out fuse is prone to abnormal breaking or failure when the distribution transformer is under load. Closed, the occurrence of this situation will cause damage to the distribution transformer and electrical equipment, and there is a great potential safety hazard;...
