The copper plate 2 is in contact with the sliding seat 14. When the measurement is completed and the sliding seat 14 is released, it will be restored to its initial position by the elastic action of the connecting spring 18. The outer wall of the sliding seat 14 is elastically connected with a measuring contact 16 through a reset spring 15. The measuring contact 16 is slidably connected to the inner wall of the sliding seat 14. The measuring contact 16 is electrically connected to the measuring device 8. Through the contact between the measuring contact 16 and the copper busbar 2, the measured value is electrically transmitted to the inside of the measuring device 8 and displayed on the display screen on its surface. One end of the reset spring 15 is fixedly connected to the inner side wall of the measuring contact 16, and the other end of the reset spring 15 is fixedly connected to the outer wall of the sliding seat 14. When it is necessary to perform insulation measurement on a certain group of copper busbars 2 separately, the measuring contact 16 at its current position is pressed to move it inside the sliding seat 14. After the measurement is completed, the measuring contact 16 is released and it will be restored to its initial position by the elastic action of the reset spring 15.

[0025] Furthermore, a handle 17 is fixedly connected to the outer wall of the sliding seat 14, and the sliding seat 14 can be controlled by the handle 17 to move on the inner wall of the cabinet door 7, so that the three groups of measuring contacts 16 can be moved and measured synchronously at the same time. Three groups of copper bars 2 are fixedly connected to the inner side wall of the cabinet 1, and cables 3 are fixedly installed on the surface of the copper bars 2. The surface of the copper bars 2 is fixed to the surface of the cables 3 by bolts, and the end of the cables 3 away from the copper bars 2 is fixedly connected to the motor 4. Four groups of mounting seats 5 are fixedly connected to the outer side wall of the cabinet 1. The inner wall of the mounting seat 5 is provided with two groups of upper and lower through holes, and the block 13 is plugged into the through holes. The plugging between the two can firmly fix the cabinet 1 and the fixed seat 6 together. The inner wall of the mounting seat 5 is slidably connected with the fixed seat 6, and the bottom end of the fixed seat 6 is provided with an external thread.

At this time, the cabinet 1 is manually supported to make the through holes of the four groups of mounting seats 5 on its outer wall contact with the outer wall of the fixing seat 6. When the through holes of the mounting seat 5 move on the outer wall of the fixing seat 6, the inclined surfaces of the two groups of blocks 13 on the inner wall of the fixing seat 6 are squeezed, allowing them to move inward on the inner wall of the fixing seat 6. When the through holes on the inner wall of the mounting seat 5 move to the blocks 13, the sliding rods 11 fixedly connected with the two groups of blocks 13 are pushed outward by the elastic action of the limit springs 12, and plugged into the through holes at the current position of the mounting seat 5, thereby firmly fixing the cabinet 1 on the surface of the fixing seat 6.

[0027] At the same time, when it is necessary to measure the insulation of the three groups of copper busbars 2, the handle 17 can be grasped to press the entire group of sliding seats 14 to move on the inner wall of the cabinet door 7. At the same time, the three groups of measuring contacts 16 will synchronously follow its movement to contact the copper busbar 2, so that the measured value can be displayed through the measuring device 8. When the measurement is completed, the handle 17 is released, and the sliding seat 14 is elastically acted upon by the connecting spring 18 to restore it to its initial position. Alternatively, a single group of measuring contacts 16 can be pressed to move on the inner wall of the sliding seat 14 to contact the copper busbar 2. When the measurement is completed, the measuring contacts 16 are released and are elastically acted upon by the reset spring 15 to restore them to their initial position.
