Short circuit method of strain insulator string

Abstract

The invention relates to a short circuit method of a strain insulator string. The short circuit method of a strain insulator string is characterized by comprising the following steps that 1) a strain insulator string short circuit device is prepared; (2) the insulating telescopic rod is lifted by hand, and the insulator string fitting presses the sealing device and rotates downwards with the second screw as a rotating point; (3) when the insulator string fitting reaches the bottom of the U-shaped opening, the first screw rod of the sealing device returns to a left groove in a left upper fork plate of the fork tool; 4) the insulator string fitting leaves the U-shaped opening between the right part of the sealing device and the upper end of the right upper fork plate; the clamp of the personal security wire clamps the insulator string fitting to realize short circuit of the strain insulator string; the insulating telescopic rod is operated to separate the hook from the circular ring, and the insulating telescopic rod, the fork and the sealing device are retracted; and 5) after the work is finished, the insulating rope of the personal security wire is pulled, the clip of the personal security wire is separated from the insulator string hardware, and the personal security wire, the circular ring and the insulating connecting rope are withdrawn. When the method is used for short circuit of the insulator string, time and labor are saved.

Description

technical field [0001] The invention relates to a short-circuiting method for tension insulator strings. Background technique [0002] With the rapid development of the economy, the transmission lines are increasing day by day, and there are more and more crossing lines, which leads to more and more prominent problems of induced electricity on the power outage maintenance lines. In order to prevent induction electric injury, the State Grid Corporation of China's "Safety Work Regulations for Electric Power Construction (Part II: Lines)" stipulates: "Before the work of touching or approaching the wires, a personal security line must be hung up" "When crossing the non-stop line , the wires across both ends of the gear should be grounded, and the tension insulator strings should be short-circuited with conductors before the tension tower is hung up. [0003] At present, for the problem of induced electricity on the tension insulator strings, the original method is to short-circ...

Problems solved by technology

However, because the transmission tower is tall and the diameter of the aluminum wire is small, there is a risk that the operator will short-circuit
