The feeding table 31 and the test bench 1 are both provided with a plurality of feeding rollers 11. The feeding rollers 11 are used to transport the test base 2 to move. In specific implementation, before conducting the experiment, the circuit breaker needs to be installed on the support frame 21, the circuit breaker is connected to the support frame 21 by rotation, and then the test base 2 is placed on the feeding table 31. The motor drives each feeding roller 11 to rotate and transport the test base 2 toward the test bench 1, thereby completing the feeding of the circuit breaker. The test bench 1 is composed of a combination of insulating material and non-insulating material, so it should be kept away from the test bench 1 during the experiment.

[0039] like Figure 1 and Figure 2As shown, the feeding mechanism 3 further includes an offset adjusting seat 32. The offset adjusting seat 32 is slidably connected to the detection table 1 and driven by a cylinder.

A pushing member 33 is also provided on the offset adjusting seat 32, and the pushing member 33 is used to push the offset adjusting member 321 to move towards the detection base 2. In specific implementation, the offset adjusting seat 32 moves along the length direction of the detection table 1 and is driven by a cylinder. The driving member 322 uses two cylinders. The two cylinders push the driving member 322 from two directions so that the offset adjusting member 321 can rotate along a square trajectory. During adjustment, the detection base 2 can be accurately aligned by the extrusion of the offset adjusting member 321. The pushing member 33 also uses a cylinder, and the offset adjusting member 321 is integrally installed on the pushing member 33, so it can be entirely pushed out by the pushing member 33.

The output shaft of the speed reducer 42 can be传动连接 with the circuit breaker to drive the mechanical energy of the circuit breaker to flip. The sensor 43 uses a proximity switch, and a convex block is provided on the output shaft of the speed reducer 42. When the convex block approaches the sensor 43, the circuit breaker can just flip 180 degrees for subsequent detection.

[0041] As Figure 3 and Figure 5 shown, a control mechanism 5 is also provided beside the detection table 1. The control mechanism 5 can be electrically connected to the flipping mechanism 4 and the circuit breaker. The control mechanism 5 is used to supply power to the flipping mechanism 4, and the control mechanism 5 can also detect and switch the opening and closing of the circuit breaker.

The other mating socket 22 is electrically connected to the circuit breaker and detects and controls the opening and closing of the circuit breaker after being electrically connected to the control connector 521. In specific implementation, both control connectors 521 are connected to the power supply and can supply power to the corresponding mating sockets 22. When connected, the motor 41 can be controlled to flip the circuit breaker, and at the same time, the opening and closing of the circuit breaker can be detected and switched.

[0042] As It should be noted that the "传动连接" in the original text is not a standard English expression.

When high and low voltage electricity needs to be connected, it is connected through the insulators 611 on both sides. When connected, the insulator 611 is aligned with the copper sheet connector on the circuit breaker to complete the power connection.

Install the circuit breaker in advance and feed the detection base 2 into the detection table 1 through the feeding mechanism 3; b.

[0047] Working principle: Embodiment 2

[0048] The main difference between the second embodiment and the first embodiment is that the bottom of the detection platform 1 of the second embodiment is further provided with a grounding protection cover 8, which completely wraps the bottom of the detection platform 1. The grounding protection cover 8 is integrally arranged with the connecting piece in the first embodiment. When grounding is required, the overall grounding can be achieved by contacting the grounding rod 71. A plurality of positioning rods 81 are arranged in the grounding protection cover 8, and the positioning rods 81 are all rotatably connected to the grounding protection cover 8, and the positioning rods 81 are all transmission connected to the feed roller 11.
