Frame-type circuit breakers require performance testing (such as withstand voltage testing) before shipment. Conventional technology requires that when two types of frame-type circuit breakers are produced, the workshop must be equipped with at least two withstand voltage testing devices to accommodate both types. These two devices require considerable installation space and increase equipment investment. Utility Model Content

[0024] The structure of a withstand voltage detection device for a frame circuit breaker in an embodiment of the utility model is as follows Figures 1 to 7As shown, it includes a withstand voltage detection module 2 mounted on a main frame 1, a lifting drive device 3 arranged at the lower front of the withstand voltage detection module 2, and a conveyor line 4 arranged along the left and right directions for conveying the frame circuit breaker passing above the lifting drive device 3. The lifting drive device 3 is used to drive the frame circuit breaker to move upward and away from the conveyor line 4. The withstand voltage detection module 2 includes a mounting frame 21 and contact modules 22 arranged in two rows on the mounting frame 21. Each contact module 22 includes a contact 221; the mounting frame 21 is suitable for being driven by a first driving mechanism 23 to move in the front and rear directions and by a second driving mechanism 24 to move in the up and down directions. All contact modules 22 are adjustable in position relative to the mounting frame 21 in the up and down directions, and some or all of the contact modules 22 are adjustable in position relative to the mounting frame 21 in the left and right directions so that all contacts 221 correspond to the conductive plates on the frame circuit breaker. With the above-mentioned structure in this embodiment, during operation, the frame circuit breaker moves to the top of the lifting drive device 3 through the conveyor line 4, and then is driven to rise by the lifting drive device 3. The withstand voltage detection module 2 is driven by the first drive mechanism 23 and the second drive mechanism 24 to move to a position corresponding to the frame circuit breaker, and is connected by docking the contact modules 22 with the conductive plates on the frame circuit breaker. At least part of the contact modules 22 can be adjusted in the left and right directions and the up and down directions relative to the mounting frame 21. By adjusting the position of the contact module 22 to correspond to the conductive plates on the frame circuit breakers of corresponding specifications, it can adapt to the detection of different types of frame circuit breakers. In this way, withstand voltage testing of frame circuit breakers of two specifications is achieved on the same device. Compared with using two detection devices, its installation occupies less space, the equipment investment is small, and it has better applicability.

[0025] As a specific implementation method of this embodiment, the main frame 1 is provided with an installation slide 5 which can be moved up and down, and the second driving mechanism 24 is installed on the main frame 1, and is used to drive the installation slide 5 to move up and down relative to the main frame 1. The installation frame 21 can be moved forward and backward and is set on the installation slide 5. The first driving mechanism 23 is installed on the slide 5, and is used to drive the installation frame 21 to move forward and backward relative to the installation slide 5. The first driving mechanism 23 cooperates with the second driving mechanism 24 to drive the pressure resistance detection module 2 to move in the up and down directions and the front and back directions.

[0026] The lifting drive device 3 in the embodiment includes a support bracket 31 for supporting the frame circuit breaker and a third drive mechanism 32 for driving the support bracket 31 to move up and down. When the support bracket 31 is driven upward by the third drive cylinder 32, the frame circuit breaker is pushed upward to a certain height.

[0027] In this embodiment, a support plate 41 for placing a frame circuit breaker is supported on the conveyor line 4, and the support plate 41 can slide along the length direction of the conveyor line 4, and the frame circuit breaker is placed on the support plate 41, and then the support plate 41 is driven to drive the frame circuit breaker to move above the lifting drive device 3, so that the lifting drive device 3 can drive it to rise. Furthermore, a positioning hole is provided on the support plate 41, and a positioning column 311 suitable for cooperating with the positioning hole is provided on the support bracket 31. When the third driving mechanism 32 drives the support bracket 31 to rise, the positioning column 311 cooperates with the positioning hole, so that the support plate 41 can be effectively positioned on the support bracket 31.

[0028] In this embodiment, the first driving mechanism 23 , the second driving mechanism 24 and the third driving mechanism 32 all adopt cylinders.

[0029] For further information, see Figures 6 to 8 As shown, the contact module 22 in this embodiment also includes a mounting base 222 and a connecting rod 223. The connecting rod 223 can move in the front-to-back direction and a spring 224 is provided between the connecting rod 223 and the mounting base 222 to provide a forward elastic force for the connecting rod 223. The contact 221 is fixed to the front end of the connecting rod 223. The connecting rod 223 is connected to the circuit on the device to form a contact for electrical connection. Under the elastic force of the spring 224, the contact 221 can elastically abut against the conductive plate on the frame circuit breaker and maintain a good electrical connection.

[0030] In this embodiment, the up and down and left and right movements of the contact modules 22 relative to the mounting frame 21 are driven by the adjusting cylinder 25. The adjustment cylinder 25 is extended and retracted to drive the position of each contact module 22 to change, thereby adapting to the detection of frame circuit breakers of different specifications.
