Problems solved by technology

The currently used insulating bracket cannot use a jack to transfer the force, so that the bolts fixing the insulator are under downward pressure without a jack. When using a jack, all the bolts on the fixing insulator must be loosened, which makes disassembly extremely inconvenient; The bolts on the inner side of the adjacent insulator do not have enough space for operation, thus making it difficult to replace the insulator
It is very unsafe to replace insulators

Abstract

The invention discloses a DC bus bar insulating support, which comprises insulators (2), wherein each group of the insulators are fixed between a lower support plate (1) and an upper support plate (3) through bolts (4); the lower support plate (1) is fixed on a lower support (8); a support (5) is fixed on the upper support plate (3); an upper support (10) is arranged above the support (5); secondsupport plates (9) having the same number as that of the insulators (2) are fixed below the upper support (10); and bolts (7) are connected on the second support plate (9) and are supported on the corresponding support (5). The DC bus bar insulating support has the advantages of scientific structure, convenient replacement of the insulators, and uniform pressure on the insulating support, and canovercome the disadvantages in the prior art.

Description

technical field [0001] The invention relates to a DC busbar, in particular to an insulating support for the DC busbar. Background technique [0002] In the non-ferrous electrolysis plant, after the rectifier transformer unit converts the alternating current into direct current, it is transmitted to the confluence bus through the DC branch bus, and then transmitted to the electrolysis workshop by the confluence bus. The branch busbar is welded on the confluence busbar, and the confluence busbar is welded section by section on site. The busbars installed outdoors use insulating brackets to support the busbars and insulate them. The insulating bracket is composed of supports such as insulators and channel steel. According to the actual operation, it is found that the insulator will be damaged after a period of time. The currently used insulating bracket cannot use a jack to transfer the force, so that the bolts fixing the insulator are under downward pressure without a jack....
