Ultra-high-voltage transmission line strain insulator string entering and exiting operation connecting device and use method

Abstract

The invention discloses an ultra-high-voltage transmission line strain insulator string entering and exiting operation connecting device which comprises a flexible body, a first connector, a second connector and a tightener. The flexible body comprises two first bar portions with the same length and a second bar portion, the tail ends of the two first bar portions are connected with the tail end of the second bar portion in a common-point manner to form a Y shape, one end of each first bar portion deviating from the second bar portion is connected with one end of a connecting seat of the first connector, the first bar portions are perpendicular to a U-shaped connector, one end of the second bar portion deviating from the first bar portions is connected with a connecting portion of the second connector, and the tightener is arranged on the second bar portion to adjust the overall length of the second bar portion. The connecting device has the advantages that the problem of difficulty in performing related operation due to excessive gaps between two insulator strings of a transmission line is solved, the connecting device is light in weight, reasonable in structural design and simple and convenient to mount and operate, the labor intensity of operators on towers is relieved, and working efficiency is improved.

Description

technical field [0001] The invention relates to a maintenance tool for tension insulator strings, in particular to a connection device for connecting tension insulator strings in and out of UHV transmission lines and a method for using the same. Background technique [0002] The tension insulator string of the UHV transmission line is composed of two strings of insulators connected in parallel, and the gap between the insulators is 60cm, 80cm, 100cm, etc., resulting in the following problems during the operation: [0003] 1. Usually, to replace a single-piece insulator, the operator sits on another string of insulators to carry out work, but the operator is limited by the length of the arm and torso and cannot carry out the installation and replacement work at all; currently, lapping tools are used to lap the two strings of insulators , the operator sits on the lapping tool to operate, and the operator cannot maintain balance and cannot exert force normally during the entire...

Problems solved by technology

[0003] 1. Usually, to replace a single-piece insulator, the operator sits on another string of insulators to carry out work, but the operator is limited by the length of the arm and torso and cannot carry out the installation and replacement work at all; currently, lapping tools are used to lap the two strings of insulators , the operator sits on the lapping tool to operate, and the operator cannot maintain balance and cannot exert force normally during the entire operation; it is precisely because of the large gap between the insulators that it is difficult to complete the work of replacing a single piece of insulator, and it is difficult to complete the work during the operation There are great security risks in the process;

[0004] 2. In the process of cleaning the entire string of insulators, due to the large gap between the insulators, the operator can only ride on a string of insulators to carry out the cleaning operation. The operation intensity is high and the cleaning is also difficult, and the phenomenon of unqualified cleaning quality and rework often occurs
