The bottom sides of the insulating movable slide plate 5 are slidably connected to the movable guide rails 6 through sliders, and the bottom of the insulating movable slide plate 5 is connected to the movable driving member 4. An opening is provided at one end of the mounting frame 3, and a mounting groove 7 is detachably installed at one end of the insulating movable slide plate 5. An adjusting mechanism 8 is provided inside the mounting groove 7, and a strip insulating push plate 9 is symmetrically and movably provided on the front side of the mounting groove 7, and the strip insulating push plate 9 is connected to the adjusting mechanism 8. Auxiliary insulating push plates 10 are symmetrically provided on the top of the insulating movable slide plate 5 near one end of the mounting groove 7. The installation slot body 7 of the utility model can be connected to the insulating movable slide plate 5 for use according to needs. When the auxiliary insulating push plate 10 can meet the opening operation of the switch cabinet busbar and the line side partition inside the high-voltage switch cabinet, the installation slot body 7 can be removed, and the switch cabinet busbar and the line side partition can be opened only by the auxiliary insulating push plate 10; when the switch cabinet busbar and the line side partition cannot be opened by the two auxiliary insulating push plates 10 in fixed positions, the installation slot body 7 can be connected to the insulating movable slide plate 5 for use. At this time, the position of the two strip insulating push plates 9 can be adjusted by using the adjustment mechanism 8, and then the two strip insulating push plates 9 can be used to open the switch cabinet busbar and the line side partition, thereby improving the flexibility of use of the structure of the utility model.

[0022] When the high-voltage electrical test trolley of the utility model is used, the electrical test trolley body 1 is moved to a position aligned with the trolley chamber of the high-voltage switch cabinet, and then the adjustable platform 2 is adjusted so that the insulating movable slide plate 5 on the adjustable platform 2 is in a state that it can be smoothly pushed into the trolley chamber of the high-voltage switch cabinet, and the position of the strip insulating push plate 9 is adjusted by the adjusting mechanism 8 according to the position of the busbar and line side partition of the switch cabinet, and then the insulating movable slide plate 5 is driven by the mobile driving member 4 to move to the inside of the trolley chamber of the high-voltage switch cabinet, so that the busbar and line side partition of the switch cabinet are pushed open by the strip insulating push plate 9 or the auxiliary insulating push plate 10, so that the partition is opened, the static contact is visible to the naked eye, and the personnel are easy to operate. The operator can operate by standing 2 meters away from the switch cabinet, which increases the safety distance between the personnel and the live body, eliminates the collaborative operation of two people, avoids cross operation, and increases the operation efficiency. The high-voltage electrical test operation no longer requires the cooperation of two people.

The upper end of the moving seat 402 is connected to the bottom of the insulating moving slide 5. One end of the driving screw 401 extends out of the front of the mounting frame 3 and is provided with a first knob 403. The driving screw 401 is driven to rotate by rotating the first knob 403, so that the insulating moving slide 5 connected to the driving screw 401 through the moving seat 402 moves under the guidance of the moving guide rail 6.

[0026] A connecting piece 12 is symmetrically provided on one side of the installation slot 7, and a connecting groove 13 is symmetrically provided on one end of the insulating movable slide plate 5. The connecting piece 12 is adapted to the connecting groove 13, and the connecting piece 12 is connected to the connecting groove 13 by a connecting bolt 14. The above arrangement can realize the overall disassembly of the installation slot 7 and the structure thereon.
