Problems solved by technology

When the copper bar needs to be overhauled, due to the completion of the infrastructure project, it is no longer possible to pull the copper bar out of the high-voltage cabinet in the form of a whole piece due to the influence of indoor walls, communication cabinets, battery cabinets, etc.
When working on site, it is necessary to cut off the copper bar, and then pull it out from two adjacent switch cabinets in sections. When reinstalling, it is necessary to add a connecting plate to the fracture to fix it. The main problems: 1. Cut off the copper bar It is difficult to work at the time, and it is time-consuming and laborious to pull out; 2. The process of reconnecting and fixing the copper bars is also relatively complicated. If it is tight, it may generate heat, which will affect the safety of operation.

Embodiment 1

[0036] Such as figure 1 , figure 2 Shown: a high-voltage switchgear that is easy to install copper bars, including a switchgear body 1, the side wall of the switchgear body 1 is movably connected to the top plate, and the joint between the side wall and the top plate of the switchgear is provided with a square steel The manufactured inner hoop frame 10, the top plate is fastened on the inner hoop frame 10, the side wall of the switch cabinet is provided with a copper bar installation hole 2, and an insulating sleeve 8 is arranged in the installation hole 2, A gap 4 is opened on the upper side wall of the installation hole 2 and extends through the inner hoop frame 10 to form a copper outlet. The width of the gap 4 is slightly larger than the thickness of the copper bar 7, and a seal is arranged on the gap 4 , the sealing member is a splint 12 sandwiched between the inner and outer sides of the inner hoop frame 10 at the gaps. The splint 12 and the inner hoop frame 10 are pro...

Embodiment 2

[0038] Such as image 3 As shown: the difference between this embodiment and the first embodiment is that the sealing member is a splint 12 sandwiched between the two sides of the side wall where the gap 4 is opened, and the splint 12 on the outside of the side wall is a flat plate structure. The inner splint 12 is a Z-shaped structure with two right-angle folded surfaces, and the two are combined to form a structure that clamps the side wall and the inner hoop frame 10. The splint 12 and the side wall and the splint 12 and the inner hoop frame 10 are arranged Through the through holes of the bolts 13, the splint 12 is fixed on the side wall of the switchgear body 1 and the inner hoop frame 10 through the bolts 13.

Embodiment 3

[0040] Such as Figure 4 , Figure 5As shown, the difference between this embodiment and Embodiment 1 is that the sealing member is a U-shaped sealing plate 5, and corresponding bolt holes are provided between the sealing plate 5 and the side wall of the switch cabinet body 1 The slit 4 on the top surface of the inner hoop frame 10 is provided with a groove 11 matching the thickness and width of the sealing plate 5 to accommodate the horizontal surface of the sealing plate 5, so that the upper surface of the sealing plate 5 is in contact with the sealing plate 5 after it is installed. The upper surface of the inner hoop frame 10 is flush, the side of the sealing plate 5 in contact with the side wall of the switch cabinet body 1 is longer than the other side in contact with the inner hoop frame 10, and the longer side is in contact with the switch cabinet body 1 Bolt through holes corresponding to the side wall of the switchgear body 1, the sealing plate 5 clamps the inner hoo...

Abstract

The invention discloses a high-voltage switchgear for easy installation of copper bars, which comprises a switchgear body, a copper bar installation hole is arranged on the side wall of the switch cabinet, and a The gap, the width of the gap is slightly larger than the thickness of the copper bar, thus effectively realizing the operation of the copper bar through the gap when installing or overhauling and disassembling. The installation method is improved, the process is simple, the production cost is low, the raw materials are easy to obtain, and the operation is controllable Strong, easy installation and disassembly of copper bars, high efficiency. By making minor changes to the original high-voltage switchgear, the unnecessary trouble of cutting off the copper bars during maintenance and disassembly can be effectively avoided, and the efficiency of maintenance operations can be improved and the safety and reliability of the copper bars can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electric high-voltage switch cabinets, and in particular relates to a high-voltage switch cabinet convenient for installing copper bars and a copper bar installation method thereof. Background technique [0002] There are multiple high-voltage switch cabinets distributed in the high-voltage room of the substation, which are placed side by side in the high-voltage room. The copper bar above the switch cabinet extends to other switch cabinets through the insulating sleeve on the side wall of the switch cabinet. When the copper bar is installed for the first time, the entire copper bar is usually used to pass through the insulating sleeve on the side wall of the most edge high-voltage cabinet. enter. When the copper bar needs to be overhauled, due to the completion of the infrastructure project, the copper bar can no longer be pulled out of the high-voltage cabinet in the form of a whole piece due to the in...
