Abstract

The invention relates to a bypass switch of a low-voltage switch fault. The bypass switch comprises a shell, a moulded case circuit breaker, a bus wiring device and a cable wiring device, wherein the moulded case circuit breaker is arranged in the shell, a power-inlet wiring plug of the bus wiring device is connected with an outlet port of the moulded case circuit breaker, and a power transmission wiring plug of the cable wiring device is connected with an inlet port of the moulded case circuit breaker. Compared with the prior art, the bypass switch has the advantages of low installation requirements and quick recovery of power-supply circuit and the like, is carried conveniently, and can replace a fault circuit breaker in box-type transmission temporarily.

Description

technical field [0001] The invention relates to a low-voltage switch, in particular to a low-voltage switch fault bypass switch. Background technique [0002] The circuit breakers used in different box substations in different regions generally coexist with multiple brands, and circuit breakers often experience power outages due to overload during peak power consumption. The installation sizes of circuit breakers of various brands are different. However, the backup circuit breakers cannot be stored for a long time by multiple brands, and the timely and rapid restoration of power supply of the line cannot be realized. Therefore, it is necessary to find a bypass switch that can be replaced for different circuit breakers. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the above prior art and provide a low-voltage switch fault bypass switch that is easy to carry, has low installation requirements, can be used to temporari...
