[0022] Working principle: when in use, install the circuit breaker to be tested on the clamping seat 17, and then rotate the handle 18. The handle 18 drives the bidirectional threaded rod 16 to rotate. While the bidirectional threaded rod 16 rotates, the clamping plate 15 moves in opposite directions. The clamping plate 15 clamps the circuit breaker. Then the first motor 11 drives the screw rod 12 to rotate. When the mounting seat 10 moves to the lower position of the hot air pipe 9, the first motor 11 stops moving at this time, and the wires inside the wire storage box 8 are connected to the circuit breaker. Then the hot air blower 3 works, and the hot air is transported to the circuit breaker through the hot air pipe 9. At this time, the circuit breaker can be tested with hot air. After the test is completed, the guide is released, and the first motor 11 then rotates.

Reconnect the wire to the circuit breaker, and the second motor 24 drives the eccentric wheel 23 to rotate. While the eccentric wheel 23 rotates, a force is applied to the guide wheel 22. The guide wheel 22 drives the top rod 20 to reciprocate up and down. The top rod 20 continuously applies a force to the clamp seat 17, and the clamp seat 17 reciprocates on the transmission seat 14, thereby simulating vibration. In this process, the cooperation between the first motor 11, the screw rod 12 and the mounting seat 10 increases the automation level of the device. The cooperation between the hot air blower 3, the hot air pipe 9 and the heater 7 enables the device to simulate a high temperature environment and test the operating status of the circuit breaker in a high temperature environment. The cooperation between the second motor 24, the eccentric wheel 23, the guide wheel 22 and the top rod 20 can simulate the use of the circuit breaker under vibration, thereby increasing the comprehensive testing capability of the device.
