Drop type fuse is a common short-circuit protection switch, which has the characteristics of economy, easy operation and strong adaptability to outdoor environment. It is widely used in the branch lines of 10kV distribution lines and distribution transformers for primary side protection and equipmen

High voltage isolators, load switches and circuit breakers are all high voltage electrical devices used to close and disconnect circuits. The tasks they carry in the circuit are also different. Isolation switch can only be used to cut off the line and cut off the power supply without load current, i

The structural characteristics and functions of the load switch: the high voltage load switch is a high voltage electrical appliance between the high voltage isolation switch and the high voltage, which is similar to the circuit breaker in performance and similar to the high voltage isolation switch

The application of optical vacuum circuit breaker module to multi-break vacuum circuit breaker puts forward higher requirements for power reliability and low power consumption, so the design of optical vacuum circuit breaker module with low power consumption is carried out. The working principle of
