Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage switch cabinets, and in particular to a high-voltage switch cabinet with a convenient grounding structure. Background Art

[0002] The main function of the switchgear is to open and close, control and protect electrical equipment during the power generation, transmission, distribution and energy conversion of the power system. High-voltage switchgear refers to the switchgear used for power generation, transmission, distribution, energy conversion and consumption in the power system to play the role of opening and closing, control or protection;

[0003] Most of the existing high-voltage switchgear is grounded using external grounding equipment, which requires secondary installation during use, is less convenient to use and less convenient for subsequent maintenance. For this reason, we propose a high-voltage switchgear with a convenient grounding structure.

[0004] The utility model with Chinese patent application number CN202220655653.3 discloses a high-voltage switch cabinet with a convenient grounding structure, which relates to the technical field of high-voltage switch cabinets, including a switch cabinet body, a plurality of grounding grooves are evenly opened at the bottom of the inner body of the switch cabinet body, and a grounding frame is arranged on the upper surface of the grounding grooves, and the grounding frame is fixedly connected to the inner bottom of the switch cabinet body, a plurality of reinforcing ribs are fixedly connected to the bottom of the switch cabinet body near the grounding grooves, a top cover is snap-connected to the upper surface of the switch cabinet body, a back plate is plug-connected to the rear surface of the switch cabinet body, a sealing frame is arranged on the top of the back plate, reinforcing rods are symmetrically fixedly connected to the inner surface of the switch cabinet body, and a password cabinet is fixedly connected to the front surface of the switch cabinet body near the bottom. The utility model has a plurality of grounding grooves at the bottom of the switch cabinet body, and grounding is performed by cooperating with the grounding grooves with the ground wire. At the same time, a grounding frame is arranged to limit the movement of the ground wire, and reinforcing ribs are arranged at the bottom of the high-voltage switch cabinet to increase the stability of the device support.

[0005] However, it can be learned from the drawings in its specification that the bottom of the high-voltage distribution cabinet body is grounded through the cooperation of the grounding groove and the mounting frame. However, when the high-voltage distribution cabinet body is placed, the bottom of the high-voltage distribution cabinet body is flat, which makes it inconvenient to move and adjust the position of the high-voltage distribution cabinet body, and it is inconvenient to make the grounding groove correspond to the grounding position of the ground wire, affecting the connection effect.

[0011] Furthermore, a through hole is provided at the top of the limiting frame, a small hole is provided at one side of the limiting frame, and a limiting plate is fixedly connected to the front side of the placement box.

[0012] Furthermore, two stabilizing rods are fixedly connected to the top of the lifting plate, and the stabilizing rods pass through the middle of the fixed plate and are slidably connected to the fixed plate.

[0013] Furthermore, the heights of the rotating wheel and the connecting plate are smaller than the height of the protective frame, and the mounting frame corresponds to the grounding groove one by one.

[0014] Furthermore, the input end of the liquid pump is connected to the inner cavity of the liquid tank, and the output end of the liquid pump is connected to the liquid inlet pipes of the two hydraulic push rods through a three-way pipe.

Moreover, the protective frame and the sealing frame are fitted with the ground, which can improve the sealing performance of the bottom of the high-voltage distribution cabinet body and the ground, avoid contact between liquid and the ground wire due to water accumulation on the ground, and play a protective role.

[0017] 2. The utility model can also prevent dust from entering the interior of the high-voltage distribution cabinet body through the dustproof plate, and facilitate heat dissipation. The placement box is limited by a limit frame, and dry particles are placed inside the placement box to prevent moisture from entering the interior of the high-voltage distribution cabinet body. The stability of the up and down movement of the lifting plate can be improved by the stabilizer bar, and the sealing frame can be conveniently limited and placed through the card slot to improve the stability of the placement of the sealing frame.
