Standby automatic switch simulation breaker test apparatus

The utility model provides a standby automatic switch simulation breaker test apparatus, and relates to the technical field of substation support equipment. An opposite end of one end of a power-interruption delay normally-close contact of a first time relay (1TJ) is connected with one end of a first pair of normally-open contacts of a first contactor (1HJ), and the other end of the first pair of normally-open contacts of a first contactor (1HJ) is connected with one end of a normally-open contact of a third button (HA1), the anode of a first diode (V1) and one end of a coil of the first contactor (1HJ). One end of a normally-close contact of a first button (TA1) is connected with one end of a first pair of normally-open contacts of a second contactor (1KKJ), and the other end of the first pair of normally-open contacts of a second contactor (1KKJ) is connected with the cathode of the first diode (V1) and one end of a coil of the second contactor (1KKJ). According to the utility model, the test apparatus can
