Problems solved by technology

When overhauling the busbars in the switchgear, a grounding trolley is usually used to ground the busbars to protect the safety of technicians using electricity. However, the grounding trolley is completely exposed on the ground in the high-voltage room area, and the handling is time-consuming and laborious, posing safety hazards
[0003] In order to solve this problem, the existing storage device includes a cabinet door and a cabinet body. This device is used for fixed-point storage of grounding trolleys. The cabinet door is set on the cabinet body. However, after the cabinet door is opened, the cabinet door is likely to rub against the field equipment. Collision, resulting in door damage and equipment failure, increasing maintenance costs
Another existing storage device includes a cabinet body and a door curtain. The cabinet body is provided with a curtain shaft for hanging the door curtain to reduce the entry of dust, but the door curtain cannot completely block the entry of dust, and the grounding trolley is inside the cabinet. When stored for a long time, once the wiring contacts of the grounding trolley are covered with dust, it will cause poor contact of the power line and affect the safe operation of the equipment

Embodiment 1

[0037] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0038] Such as Figure 1-Figure 4 As shown, this embodiment provides a grounding trolley vertical cabinet. When the busbar of the substation is overhauled, the grounding trolley vertical cabinet is usually equipped in the high voltage room area, which is used for fixed-point storage of the grounding trolley and provides convenience for handling the grounding trolley. However, in the prior art, the cabinet door is arranged on the cabinet body. When the cabinet door is opened, it takes up space and is prone to friction and collision with field equipment and personnel. Safe operation of equipment.

[0039] In order to solve this problem, specifically, the grounded trolley vertical cabinet includes a base 1 , a protective cover 2 and a baffle 3 . The grounding trolley is placed on the base 1. The base...

Embodiment 2

[0051] Such as Figure 6 As shown, this embodiment provides a grounded trolley vertical cabinet, and on the basis of the first embodiment, the grounded trolley vertical cabinet also includes a storage box 8 . Specifically, the storage box 8 is arranged at the lower end of the base 1, and is used for storing commonly used identification cards, tools and parts, etc. The storage box 8 includes a box body 81 and a drawer 82, and the box body 81 is fixedly arranged on the base 1. One side of the body 81 is provided with an inlet and outlet, and the drawer 82 can be accommodated in the inside of the box body 81 through the inlet and outlet, and is slidably connected to the box body 81. The intervals in the vertical direction are set to play the role of classification.

[0052] Further, the storage box 8 also includes a moving slide rail and a fixed slide rail. Specifically, the number of moving slide rails is two, and the two moving slide rails are threadedly connected to both sid...

Abstract

The invention belongs to the technical field of electrical safety, and discloses a grounding trolley vertical cabinet which comprises a base, a protective cover and a baffle. The base is used for supporting the grounding trolley, the protective cover is arranged on the base, the protective cover is provided with a sliding groove and a containing cavity used for containing the grounding trolley, an opening is formed in one side of the containing cavity, the protective cover and the baffle form a closed space, and the dustproof effect is good. A rotating part is arranged on the baffle and located in the sliding groove, and the baffle can rotate relative to the protective cover through the rotating part so that the baffle can have an opening position and a closing position. When the baffle is located at the closing position, the baffle shields the opening, and a closed dust-free environment is provided for the grounding trolley. When the baffle is located at the opening position, the baffle opens the opening, the baffle can slide in the length direction of the sliding groove through the rotating piece and is used for storing and taking the grounding trolley, the baffle can be hidden and stored, the space utilization rate is increased, and the baffle is prevented from colliding with the grounding trolley.

Description

technical field [0001] The invention relates to the technical field of electrical safety, in particular to a grounded trolley vertical cabinet. Background technique [0002] In the process of power generation, transmission, distribution and power conversion in the power system, the substation needs to use switchgear equipment to control and protect the electrical equipment. When overhauling the busbars in the switchgear, a grounding trolley is usually used to ground the busbars to protect the safety of technicians using electricity. However, the grounding trolley is completely exposed on the ground in the high-voltage room area, and the handling is time-consuming and laborious, posing safety hazards. [0003] In order to solve this problem, the existing storage device includes a cabinet door and a cabinet body. This device is used for fixed-point storage of grounding trolleys. The cabinet door is set on the cabinet body. However, after the cabinet door is opened, the cabinet...
