Description

Cabinet structure of a 12kV air-insulated armored switchgear

technical field

The utility model relates to the technical field of switch cabinets, in particular to a cabinet body structure of a 12kV air-insulated armored switch cabinet.

Background technique

In recent years, air-insulated metal-enclosed switchgear has been widely used in medium-voltage power transmission and distribution systems, and the design of the switchgear, especially the structural design, is the most basic and most important part. The traditional switchgear structure usually adopts a bottom plate. The front and rear cabinets of the switchgear cannot be assembled separately. less efficient. At the same time, as the cost of urban land continues to increase, the market has increasingly strong requirements for the miniaturization of switchgear products, and the traditional switchgear is bulky and gradually unable to meet the needs of users.

Utility model content

The purpose of this utility model is to provide a cabinet structure of a 12kV air-insulated armored switch cabinet to solve the above technical problems.

In order to achieve the above object, the utility model adopts the following technical solutions:

A cabinet structure of a 12kV air-insulated armored switchgear, including a front cabinet and a rear cabinet; the front cabinet includes an instrument room, a circuit breaker room, and a lower compartment from top to bottom; the rear cabinet includes a bus bar from top to bottom Room and cable room; the front cabinet and the rear cabinet are composed of separate cover plates and bases.

The front cabinet and the rear cabinet are connected by screws.

The base of the switchgear formed after the front cabinet and the rear cabinet are assembled is 1450mm long and 600mm wide.

The instrument room, circuit breaker room and lower compartment are separated by steel plates; the busbar room and cable room are separated by steel plates.

Compared with the prior art, the utility model has the following advantages: the cabinet structure of the utility model is completely metal armored, adopts a modular design, spliced and assembled structure, and the assembly process is simple, which is convenient for the factory to carry out large-scale production; at the same time, the occupied area is obvious Smaller than other similar products to meet the needs of users. The front and rear cabinets of the switch cabinet adopt modular design. The cabinet body is composed of two parts: the front cabinet and the rear cabinet. The front cabinet and the rear cabinet adopt separate cover plates and bottom plates, which are formed independently; The installation and commissioning are completed; the side plate column of the rear cabinet adopts a rivet nut structure, and the screws can be screwed in from the front cabinet to realize the assembly of the front and rear cabinets, thereby completing the installation of the entire switch cabinet; the connecting screws of the front and rear cabinets can also be removed from the front cabinet for maintenance and replacement. Remove the front cabinet.

Fig. 3 is the structural representation of the rear cabinet of the present utility model;

Fig. 4 is the side view of Fig. 3;

Fig. 5 is a schematic structural view of the cabinet body formed after the front cabinet and the rear cabinet of the utility model are assembled.

Detailed ways

The technical scheme of the utility model will be described in detail below in conjunction with the accompanying drawings.

Please refer to Figures 1 to 5, Figures 1 and 2 are the front cabinet structure, Figures 3 and 4 are the rear cabinet structure, and Figure 5 is the cabinet structure formed by splicing the front and rear cabinets.

As shown in Figure 1 and Figure 2, it includes instrument room 1, circuit breaker room 2 and lower compartment 3 from top to bottom; as shown in Figure 3 and Figure 4, it includes busbar room 4 and cable room from top to bottom 5. Among them, the front cabinet and the rear cabinet adopt separate cover plate and bottom plate, which are formed independently. Internal components can be installed and debugged in the front and rear cabinets respectively. The side column of the rear cabinet adopts a rivet nut structure, and the screws can be screwed in from the front cabinet to realize the assembly of the front and rear cabinets, thus completing the installation of the entire switch cabinet. During maintenance and replacement, the connecting screws of the front and rear cabinets can also be removed from the front cabinet, and the front cabinet can be removed separately.

Please refer to Figure 5, the size of the bottom plate of this switchgear is (width×depth, unit mm) 600×1450=0.87m ² , compared with the existing 1.2m ² cabinet, the floor area is reduced by about 30% , which greatly improves the land utilization rate and can be widely used in urban construction, especially in areas that are sensitive to the area occupied by switch cabinets.
