Pressure finger and contact finger assembly tool

Abstract

The invention relates to a pressure finger and contact finger assembly tool, which comprises a support frame with an open end, wherein the open end of the support frame is provided with connecting holes used for being connected with process holes in the end face of a GIL conductor through bolts. The pressure finger and contact finger assembly tool further comprises a push plate used for pushing acontact finger pressing ring and a telescopic mechanism used for driving the push plate to move in a reciprocating manner along an axial direction of the GIL conductor. Compared with an installation mode of clinging to the surface of the conductor, the pressure finger and contact finger assembly tool can prevent damages to the surface of the conductor to affect the insulation performance of the conductor. In addition, the pressure finger and contact finger assembly tool also has good alignment performance, thereby enabling the push plate to accurately pushing the contact finger pressing ring,and ensuring an elastic retaining ring to be not interfered in the installation; direct connection is carried out through the bolts, thereby not only being firm and reliable, but also being very convenient to disassemble; and more importantly, the tool can realize fast assembly of the elastic retaining ring through a simple structure, so that the assembly efficiency is significantly improved, andthe assembly safety is relatively high.

Description

technical field [0001] The invention relates to an assembly tool for pressing and contacting fingers. Background technique [0002] GIL refers to gas-insulated technology enclosed transmission lines. Since the successful development of GIL by the High Voltage Power Corporation of the United States and the Massachusetts Institute of Technology in the United States was put into commercial operation in 1972, GIL has been widely used worldwide. This ultra-high-voltage power transmission method has compact and flexible layout, large transmission capacity, effective electromagnetic shielding, reliable and safe operation, and provides an ideal choice for long-distance power transmission systems. [0003] The connection of the conductors at the adjacent two ends of the GIL pipeline busbar adopts the HM type pressure finger plug-in assembly. The contact elements are arranged at the bottom of the conductor socket, and the plugs of the adjacent conductors are silver-plated, and the poc...

AI Technical Summary

Problems solved by technology

Since the HM contact finger 13 adopts the pressure-contact structure of the spring 15, the pressure of the spring 15 is relatively high. If the elastic retaining ring 17 is to be smoothly installed into the retaining ring groove, the worker needs to press down the contact finger pressing ring 16 hard, and the operation process is quite difficult. , the assembly efficiency is extremely low, and a little carelessness may cause the elastic retaining ring 17 to pop out, endangering the safety of the operators
