[0002] High-voltage ring main units are used in distribution stations and box-type substations in load centers such as urban residential areas, high-rise buildings, large public buildings, factories and enterprises. High-voltage ring main units are designed to improve power supply reliability and enable users to obtain power from two directions. The power supply network is usually connected in a ring shape. This power supply method is referred to as ring network power supply.

In this embodiment, when using the high-voltage ring network cabinet, according to the requirements of different distances of the mounting plate 8, the slider 10 slides in the slide rail 9 to drive the mounting plate 8 to move back and forth, thereby changing the distance of the mounting plate 8. When the mounting plate 8 moves to the specified distance, the second pin 12 is inserted into the second limiting holes 11 corresponding to the left and right sides of the ring network cabinet body 1 and the outer surfaces of the slide rail 9 and the slider 10. The ring network cabinet body 1, the slide rail 9 and the slider 10 are locked to achieve limiting. Therefore, when it is necessary to inspect the electrical components inside the ring network cabinet, the mounting plate 8 can be pulled out from the inside of the ring network cabinet for inspection, which expands the inspection space, facilitates the inspection of the electrical components, and improves the safety during the inspection process.

[0023] The outer surface of the bottom of the three mounting plates 8 is provided with a groove 16, and the two grooves 16 are centrally symmetrical about the center of the mounting plate 8. A universal joint 15 is provided inside the groove 16 near the outer surface of the cabinet door 2. A telescopic rod sleeve 17 is provided inside the groove 16. One end of the telescopic rod sleeve 17 is fixedly connected to the universal joint 15. A telescopic rod 21 is inserted into the telescopic rod sleeve 17.

Therefore, when it is necessary to inspect the electrical components inside the ring network cabinet, the mounting plate 8 can be pulled out from the inside of the ring network cabinet for inspection, which expands the inspection space, facilitates the inspection of the electrical components, and improves the safety during the inspection process.

[0029] When fixing the mounting plate 8, after pulling the telescopic rod 21 to the specified distance, the third pin 18 is inserted into the third limiting hole 19 corresponding to the outer surface of the telescopic rod 21 and the telescopic rod sleeve 17, and the telescopic rod sleeve 17 and the telescopic rod 21 are locked. At the same time, the universal joint 15 is rotated to rotate the telescopic rod 21 to the specified position. After the rotating shaft 13 rotates and drives the fixed block 4 to rotate to an angle that fits the insertion groove 16, the fixed block 4 is inserted into the fixed groove 14. At the same time, the first pin 6 is inserted into the left and right sides of the support block 5 and the first limiting holes 7 corresponding to the outer surface of the fixed block 4, and the fixed block 4 and the support block 5 are locked, thereby achieving the fixation of the telescopic rod 21.
