Problems solved by technology

[0003] (1) The size of the existing busbar bridge is a specific value, and the size of the busbar bridge used in different projects is usually different, which leads to the need to measure the size of the busbar bridge on site for each batch of projects, which increases the installation cost. Reduced installation efficiency
[0004] (2) The processing technology is complicated, which not only increases the cost of welding, grinding and spraying, but also causes environmental pollution
[0005] (3) The weight of the busbar bridge after welding is heavy, and the busbar bridge needs to be installed on the top of the 2.2m high power distribution cabinet on site, which makes its installation extremely inconvenient

Embodiment 1

[0045] Such as Figure 1 to Figure 2 As shown, according to a preferred embodiment of the present invention, the low-voltage switchgear assembled telescopic bridge frame of the present invention includes a main bridge frame 1 and piers 2 arranged at both ends of the main bridge frame 1, wherein:

[0046] The main bridge frame 1 includes two first side plates 11 on both sides, a base plate 12 at the bottom and a first cover plate 13 at the top, and the pier 2 includes four second side plates 21 around and a second cover at the top plate 22.

[0047] Such as figure 2 , Figure 4 , Figure 9 with Figure 10As shown, the top and bottom of the first side panel 11 and the second side panel 21 respectively have a first folded edge 111, 211 vertically facing inward and a second vertical edge connected to the first folded edge 111, 211. Flange 112, 212. The two sides of the bottom plate 12 respectively have third folded edges 121 facing upwards, and the third folded edges 121 on...

Embodiment 2

[0088] The telescopic structure of the low-voltage complete switchgear assembled telescopic bridge frame of this embodiment is the same as that of Embodiment 1, the difference is that the assembled structure of the main bridge frame and the pier is different, specifically:

[0089] The two first side plates 11 and the bottom plate 12 of the main bridge frame 1 do not have bending edges, the thickness of the first side plates 11 is greater than the thickness of the screws, and the first side plates 11 are fixed by parts (such as bolt and nut assembly, screws) are directly fixed on the bottom plate 12, and the first cover plate 13 is directly fixed on the top end surface of the first side plate 11 through fixing parts (such as bolt and nut assemblies, screws) , so as to realize the assembled fixed connection.

[0090] The thickness of the second side plate 21 of the pier 2 is greater than the thickness of the screw, and the second cover plate 22 is directly fixed on the top end ...

Embodiment 3

[0093] The telescopic structure of the low-voltage complete switchgear assembled telescopic bridge frame of this embodiment is the same as that of Embodiment 1, the difference is that the assembled structure of the main bridge frame and the pier is different, specifically:

[0094] The main bridge frame 1 includes a frame with a square cross section, and a first side plate 11 , a bottom plate 12 and a first cover plate 13 fixed on the frame. The frame is composed of four longitudinal beams located at the four corners of the square in the horizontal length direction of the main bridge, and horizontal beams and vertical beams connecting the longitudinal beams. The first side plate 11, the bottom plate 12 and the second A cover plate 13 is directly fixed on the frame by a fixing member (such as a bolt and nut assembly, screw), so as to realize an assembled fixed connection.

[0095] The pier 2 includes a frame with a square cross section, four second side plates 21 and a second c...

Abstract

The invention provides an assembly type telescopic bridge-shaped tray of a low-voltage switchgear. The assembly type telescopic tray comprises a main bridge-shaped tray and piers at two ends of the main bridge-shaped tray. The main bridge-shaped tray comprises two first side plates at two sides, a bottom plate at the bottom, and a first cover plate at top. Each pier comprises four second side plates and a second cover plate at the top, wherein assembly type fixed connection is adopted. The ends of the first side plates at two ends of the main bridge-shaped tray are provided with two first waist holes. A first sealing plate is arranged outside the first side plate. One end of the first sealing plate is provided with two first circular holes. Furthermore fixing members are utilized for fixing. According to the assembly type telescopic bridge-shaped tray, the length of the bridge-shaped tray can be adjusted to a certain extent, thereby greatly reducing mounting cost and improving mounting efficiency. Furthermore the assembly type telescopic bridge-shaped tray has advantages of high convenience in mounting, and high structure stability.

Description

technical field [0001] The invention belongs to the field of high-voltage and low-voltage power distribution equipment, and in particular relates to a low-voltage switchgear assembly-type retractable bridge frame. Background technique [0002] In the power distribution equipment industry, the busbar bridge usually consists of a main bridge and bridge piers arranged at both ends of the main bridge, and the two bridge piers are respectively connected to two distribution boxes. In the prior art, the main bridge frame and bridge piers are usually made of cold-rolled plates through five processes: punching-bending-welding-grinding-electroplating, and channels for laying copper bars are formed inside. The bus bridge in the prior art has the following defects: [0003] (1) The size of the existing busbar bridge is a specific value, and the size of the busbar bridge used in different projects is usually different, which leads to the need to measure the size of the busbar bridge on ...
