High-voltage circuit breaker power supply automatic conversion device

The utility model belongs to the field of conversion equipment. The utility model relates to a high-voltage circuit breaker, in particular to a high-voltage circuit breaker power automatic conversiondevice. The problem that an existing conversion device is inconvenient to disassemble, assemble and maintain a power supply automatic conversion device is solved. Proposed now is the following scheme,the switching device comprises a circuit breaker case and a switching device body located in the circuit breaker case. A partition plate is fixedly mounted in the circuit breaker case; a circuit breaker is fixedly mounted on one side of the partition plate; an insulating box body is placed on the other side of the partition plate, the conversion device body is installed in the insulating box body, the insulating box body is movably installed in the circuit breaker case, two symmetrically-arranged positioning grooves are formed in the other side of the partition plate, two symmetrically-arranged positioning bases are f
