Fixedly-installed rapid handling apparatus for distribution transformer main switch and method

Abstract

The invention relates to a fixedly-installed rapid handling apparatus for a distribution transformer main switch and a method. The rapid handling apparatus comprises a main busbar, static contact discs, moving contact discs, elastic clamps and an operating panel, wherein the main busbar adopts a rectangular structure, and consists of an upper sheet, a middle sheet and a lower sheet, wherein the upper sheet and the lower sheet are conductive copper sheets; the middle sheet adopts a PVC insulating material; the upper sheet and the lower sheet are equipped with bases used for mounting fast-acting fuses separately; four static contact discs are mounted via screws by the lower sheet on one end plane of the main busbar; the moving contact discs are mounted on the other end plane, corresponding to the static contact discs, of the main busbar; the elastic clamps are mounted between each pair of the moving contact discs and the static contact discs; the elastic clamps are connected with the moving contact discs and the static contact discs through bolts; spring shafts are symmetrically and vertically mounted on the outer end parts of the elastic clamps; and handles are mounted on the two end parts of the upper and lower spring shafts. The fixedly-installed rapid handling apparatus is high in universality, small in size, light in weight, convenient to carry, and can be applied to distribution transformer main switches of various specifications in fault handling; and after the distribution transformer main switch is replaced, the apparatus can be reused for other distribution transformer main switches for performing emergency fault handling.

Description

technical field [0001] The invention belongs to the technical field of electric power, and relates to an emergency treatment device for power distribution faults, in particular to a fixed fast treatment device and method for a main distribution switch. Background technique [0002] The main distribution switch is the main switch on the 0.4kV side of the distribution transformer. Because the internal structure and function of the main distribution switch are relatively complicated, and it works in a civil engineering station or a box-type station, it is affected by adverse factors such as high temperature, dust, and electromagnetic radiation. During the period of heavy load, the main body failure is very easy to occur, causing large-scale power outages. [0003] At present, for the failure of the main distribution switch body, it is generally handled by making temporary short-circuit cables on site or replacing the main distribution switch as a whole. To make temporary short...

AI Technical Summary

Problems solved by technology

To make temporary short-circuit cables on site, it is necessary to measure the distance between the mounting screw holes of the upper and lower busbars of the 0.4kV switchgear, cut off the cables on site, and make cable terminals. The production process is complicated and requires many experienced professionals on site to complete the production. , time-consuming and labor-intensive, and temporary short-circuit cables cannot be reused, resulting in a serious waste of materials

The other way is to replace the main switch as a whole, which has disadvantages such as manufacturers, models are varied, switch models are discontinued, spare parts are difficult to manage, and on-site replacement takes a long time.
