Novel 66kv disconnector contact-finger assembling device

Abstract

The invention provides a Novel 66kv disconnector contact-finger assembling device. The structure of the device is as follows: two angular plates (respectively provided with a clamp plate) are connected with an assembled bar (rotatablely fixed by an upper rotating handle and a lower rotating handle) by a connecting plate and a combined fixed screw, and a contact-finger clamp groove is formed between the clamp plate and the angular plate; the upper part of the assembled bar is rotatablely connected with a clamping angular plate by a rotating-bar nut, and the clamping angular plate is rotatablely connected with a fastening screw handle, one side of the clamping angular plate is connected with a rotating bar, and an end of the rotating bar is transversely provided with a rotary handle. When being used for carrying out assembling, disassembling and maintenance on disconnector contact-fingers, the device disclosed by the invention has the characteristics of time conservation, labor conservation, convenience, quickness, and no damage on the structures and appearances of the disconnector contact-fingers; and the assembling quality is ensured, the damage on components is reduced, and the occurrence probability of safety accidents is completely eradicated, therefore, the device is suitable to be used as a special tool on a mechanism for carrying out maintenance on disconnector contact-fingers in the power field.

Description

technical field [0001] The invention provides a switchgear maintenance tool in the field of electric power transmission, in particular a 66 kV novel knife switch finger assembly device. Background technique [0002] In recent years, the structure of the contact finger of the 66 kV switch has been improved, which is more reasonable and reliable, but it is more difficult to overhaul. For example, the contact finger of the knife switch has a symmetrical "double bow" shape, and is fixed on the contact finger seat by 5 pairs of contact fingers, 5 pressure springs, and a spring limit module. When assembling and overhauling the touch fingers, the touch fingers and the configured springs are mainly disassembled by hand and simple tools. After all the touch fingers are disassembled, the spring limit module will naturally slide down, which is relatively easy; but it is difficult to assemble after the overhaul is completed, because the five pressure springs It is very strong, and asse...

AI Technical Summary

Problems solved by technology

Since the maintenance time of a group of knife switches is fixed, in order to ensure that the power transmission time is not delayed, the work progress will be rushed due to lack of manpower, thereby reducing the quality of maintenance and burying hidden dangers in construction

[0004] Normally, three people are required to cooperate in the assembly of the contact finger. Using a screwdriver and hand hammer to disassemble will cause certain damage to the contact finger assembly; it is still very cumbersome and laborious to install.

After overhaul, it was found that there were scratches on various parts, changes in the linear arrangement of the contacts, damage to the spring, and damage to the spring limit module
