UHV transmission line tension insulator string access connection device and usage method

Abstract

UHV transmission line tension insulator string entry and exit operation connection device, including a flexible body, a first connector, a second connector, and a tightener. The flexible body includes two first strip parts and a second strip part with the same length part, the ends of the two first strips are connected at the same point with the ends of the second strip to form a Y shape; the end of the first strip away from the second strip is connected to the connecting seat of the first connector One end is connected and the first bar-shaped part is perpendicular to the U-shaped connector, and the end of the second bar-shaped part away from the first bar-shaped part is connected to the connecting part of the second connector, and the tightener is arranged on the second bar-shaped part Adjust the overall length of the second bar. The advantage is that it solves the problem that the gap between the two strings of insulators on the transmission line is too large and it is difficult to carry out related operations. The connection device is light in weight, reasonable in structural design, simple and convenient in installation and operation, reduces the labor intensity of operators on the tower, and improves work efficiency.

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
