Through the technical scheme, the horizontal movement of the position of the steel rope 540 can be realized so as to adapt to the extension or shortening of the bridge body, and the steel rope 540 is always kept vertical so as to ensure that the lifting effect of the bridge body is more stable.

In addition, as shown in fig. 4 and 5, the bus bar bridge for the switchgear further includes a bus bar connection assembly 700, and the bus bar connection assembly 700 includes an intermediate conductive plate 710, a first clamping plate 720, a second clamping plate 730, a first bolt 750, a third nut 760, a second bolt 780, and a fourth nut 790.

The number of the first clamping plates 720 is 2, 2 first clamping plates 720 are parallel to each other and are opposite, and 2 first clamping plates 720 are simultaneously connected to one side of the middle conductive plate 710; the number of the second clamping plates 730 is 2, 2 second clamping plates 730 are parallel to each other and are opposite to each other, and 2 second clamping plates 730 are simultaneously connected to the other side of the intermediate conductive plate 710; any one of the first clamping plates 720 is parallel to any one of the second clamping plates 730. Any one of the first clamping plates 720 is parallel to the intermediate conductive plate 710; when mounted, the intermediate conductive plate 710 is vertically connected to the upper surface of the insulating layer, i.e., the intermediate conductive plate 710 is vertically disposed.

One of the first clamping plates 720 is provided with 2 first long holes 740, the 2 first long holes 740 are respectively close to two side edges of the first clamping plate 720, the 2 first long holes 740 are parallel to each other, and the extending direction of the 2 first long holes 740 is consistent with the connecting line direction between the first clamping plate 720 and the second clamping plate 730.

The other first clamping plate 720 is also provided with 2 first long holes 740, and the upper first long hole 740 on the other first clamping plate 720 is just opposite to the upper first long hole 740 on one first clamping plate 720; the first long hole 740 on the lower side of the other first clamping plate 720 is directly opposite to the first long hole 740 on the lower side of the one first clamping plate 720.

One of the second clamping plates 730 is provided with 2 second long holes 770, the 2 second long holes 770 are respectively close to two side edges of the second clamping plate 730, the 2 second long holes 770 are parallel to each other, and the extending direction of the 2 second long holes 770 is consistent with the connecting line direction between the first clamping plate 720 and the second clamping plate 730.

The other second clamping plate 730 is also provided with 2 second long holes 770, and the upper second long hole 770 on the other second clamping plate 730 is just opposite to the upper second long hole 770 on one second clamping plate 730; the second long hole 770 of the lower side of the other second clamping plate 730 is directly opposite to the second long hole 770 of the lower side of the one second clamping plate 730.

First bolts 750 and third nuts 760 are provided between the 2 first long holes 740 of the first clamp plate 720, which are opposite, and second bolts 780 and fourth nuts 790 are provided between the 2 second long holes 770 of the second clamp plate 730, which are opposite.

The intermediate conductive plate 710, the first clamping plate 720 and the second clamping plate 730 are made of conductive material (preferably copper).

Through the technical scheme, the length of the bus bar 800 can be extended or shortened, specifically, when the bus bar 800 is used, the bus bar 800 is divided into two sections, one section is used for connecting one switch cabinet 100, and the other section is used for connecting another switch cabinet 100; the bus bar segment 800 is embedded in the middle of the 2 first clamping plates 720, is in contact with the 2 first clamping plates 720 in a fitting manner, and is clamped and fixed through a first bolt 750 and a third nut 760; the other bus bar segment 800 is embedded in the middle of the 2 second clamping plates 730, is in fit contact with the 2 second clamping plates 730, and is clamped and fixed by the second bolts 780 and the fourth nuts 790. When the bus bar 800 needs to be extended or shortened, the length of one bus bar 800 embedded into 2 first clamping plates 720 is only required to be adjusted, and the length of the other bus bar 800 embedded into 2 second clamping plates 730 is also adjusted, so that the whole length of the bus bar 800 can be extended or shortened.

Through making the length that the generating line was arranged 800 can extend or shorten, no longer need process generating line row 800 once more according to the distance between the installation on-the-spot cubical switchboard 100 promptly, can directly install labour saving and time saving has still saved the expense, has promoted the work efficiency of installation.

In addition, the first side plate 210, the second side plate 220, the third side plate 230, the fourth side plate 240, the fifth side plate 410, the sixth side plate 420, the seventh side plate 430 and the eighth side plate 440 are all made of galvanized stainless steel. The galvanized stainless steel has good durability and corrosion resistance.
