Circuit breaker test equipment capable of automatically switching alternating current and direct current

The utility model provides a breaker test device capable of automatically switching alternating current and direct current, which relates to the field of test devices and comprises a direct current power supply, an alternating current power supply, a test device and a switching mechanism. The driving cylinder can push the two conductive blocks to move back and forth between the first terminal connected with the direct current power supply and the second terminal connected with the alternating current, and the two conductive blocks are moved to contact the first terminal and the second terminal, so that alternating current and direct current are output to test equipment, namely the alternating current and direct current are switched to be input to the circuit breaker. Compared with an existing mode that different alternating current and direct current inputs are switched by manually fixing a cable through a bolt, rapid switching can be achieved, the testing efficiency is improved, and manpower resources are sa
