Description

Technical Field

[0001] The utility model relates to a component of a busbar bridge for an electric power supply system, in particular to a cabinet top busbar bridge box capable of avoiding obstacles, and is suitable for avoiding small obstacles on the top of a room. Background Art

[0002] In power supply systems, the busbars at the low-voltage output end of the main transformer in the high-voltage room are often routed through the main transformer bushings on the wall between the high-voltage room and the distribution room, and then extended via a busbar bridge to the medium-voltage incoming switchgear in the distribution room. However, the busbar bridge may encounter small obstacles on the ceiling of the room where it passes, necessitating its construction to avoid these obstacles.

[0003] The Chinese patent No. CN219833331U previously applied for by the present applicant discloses a face-to-face busbar bridge for accommodating a Z-shaped copper busbar in the middle. The structure includes a first bridge pier, a first bridge box, an intermediate bridge box, a second bridge box, and a second bridge pier, wherein the first bridge pier and the second bridge pier are respectively mounted and fixed on the top inlet and outlet of a first medium-voltage switchgear and a second medium-voltage switchgear arranged face to face. The first bridge box and the second bridge box are respectively mounted and fixed on the top sides of the first bridge pier and the second bridge pier. The intermediate bridge box is mounted and fixed between the first bridge box and the second bridge box. The height of the second bridge pier is less than that of the first bridge pier. The side of the intermediate bridge box close to the first bridge box is connected and fixed to the lower side of the side inlet and outlet of the first bridge box. A turning bridge box is mounted and fixed on the busbar bridge between the side inlet and outlet of the first bridge box and the top inlet and outlet of the intermediate bridge box. The first bridge box and the intermediate bridge box can accommodate the bending part of the busbar copper busbar between the first and second medium-voltage switchgear to be bent in a Z shape through the turning bridge box. However, the obstacle avoidance structure of this solution is relatively complex, difficult to build, and expensive. The cost of avoiding small obstacles is too high, which affects the cost control of busbar bridge construction. Summary of the Invention

[0004] In order to overcome the problems of the existing technology in that the obstacle avoidance structure is complex, difficult to build and expensive, the purpose of the utility model is to provide an improved cabinet top busbar bridge box that can avoid obstacles, which can overcome the defects of the existing technology.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a cabinet top busbar bridge box that can avoid obstacles is a hollow box body connected to the busbar bridge and composed of a front side, a rear side, a left side, a right side, a top side and a bottom side, the left side and the right side are both open, and the front side, the rear side, the top side and the bottom side are respectively provided with a front side plate, a rear side plate, a top side plate and a bottom side plate, the top side plate is a sealing plate that is easy to open, and is characterized in that: an inner concave portion for accommodating obstacles is provided between the top side and the front side or the rear side, and the inner concave portion is composed of a left wall member, a right wall member, The bottom plate is composed of a bottom plate and a support rod, the left wall member and the right wall member are respectively connected and fixed on the left and right sides of the first recessed notch on the front side plate or the rear side plate, the support rod is connected and fixed between the inner ends of the left wall member and the right wall member, the bottom plate is provided with an inner wall surface bent upward, the bottom plate is connected and fixed between the bottom sides of the left wall member and the right wall member and its inner wall surface is connected and fixed on the support rod, the top side plate is provided with a second recessed notch, the edge of the second recessed notch is placed on the top side surfaces of the left wall member, the right wall member and the support rod.

[0006] The bottom plate of the above technical solution can be tilted from the inside to the outside, and the tilt angle can be 8-12 degrees, so that small obstacles can enter the inner recess.

[0007] The left wall member, the right wall member and the top side surface of the support rod described in the above technical solution can all be formed by bending sheets.

[0008] The top side panels described in the above technical solution can be divided into several blocks, and each top surface is provided with a handle for easy opening.

[0009] The front side panel, the rear side panel or the bottom side panel described in the above technical solution may be provided with front ventilation holes, rear ventilation holes or bottom ventilation holes respectively.

[0010] The beneficial effect of the present invention is that since an inner recess for accommodating obstacles is provided between the top side and the front side or the rear side, the inner recess is composed of a left wall member, a right wall member, a bottom plate and a support rod, the left wall member and the right wall member are respectively connected and fixed on the left and right sides of the first inner recess notch of the front side plate or the rear side plate, the support rod is connected and fixed between the inner ends of the left wall member and the right wall member, the bottom plate is provided with an inner wall surface bent upward, the bottom plate is connected and fixed between the bottom sides of the left wall member and the right wall member, and its inner wall surface is connected and fixed on the support rod, the top side plate is provided with a second inner recess notch, and the edge of the second inner recess notch is placed on the top side surfaces of the left wall member, the right wall member and the support rod, so when a small obstacle appears on the ceiling of the room and hinders the construction of the busbar bridge, the small obstacle can be accommodated by the inner recess of the bridge box, so that the small obstacle no longer hinders the normal construction of the busbar bridge, so that the busbar bridge for avoiding obstacles has a simple structure, is not difficult to build, has a low cost, and the cost of avoiding small obstacles is low.
