It has the advantages of high reliability, environmental protection and durability. In the power system, the circuit breaker is a switching device that can control the current switch, which can cut off the fault circuit and avoid the expansion of the accident. During the installation of the circuit breaker, it needs to be fixed on the wall or in the high-voltage cabinet.

[0003] Existing circuit breakers are usually fixed in high-voltage cabinets by screws or directly welded. This makes it troublesome to repair the circuit breaker when a problem occurs. The circuit breaker cannot be quickly disassembled for repair or replacement. The longer the repair process takes, the greater the loss. Therefore, improvements are now made to a dry air fully insulated circuit breaker. Utility Model Content
