Wiring tool for withstand voltage test of suspension-type porcelain insulator

Abstract

The invention belongs to the technical field of the withstand voltage test of a suspension-type porcelain insulator, and specifically relates to a wiring tool for the withstand voltage test of the suspension-type porcelain insulator. The tool is characterized in that the tool comprises a plurality of vase-shaped wire holders and a wire holder connecting line; the bottom of each vase-shaped wire holder is connected with the wire holder connecting line through a wire connecting rod; the opening directions of the plurality of vase-shaped wire holders are the same; the vase-shaped wire holders are U-shaped metal plates, wherein the central parts of the vase-shaped wire holders are shaped like a belly; and springs are respectively connected between the bottoms of the left and right side plates of the U-shaped metal plates in a fixed manner. The tool meets the requirements of safety specification, and also can improve work efficiency.

Description

technical field [0001] The invention belongs to the technical field of pressure test of suspended porcelain bottles, and in particular relates to a wiring tool for pressure test of suspended porcelain bottles. Background technique [0002] like figure 1 As shown, the entire string of hanging porcelain bottles is made of a single piece of hanging porcelain bottle mechanically clamped. Each single piece of porcelain bottle needs to undergo a pressure test before it is put into use. The regulations stipulate that the pressure test value of each piece of porcelain bottle is 60kV . In order to save time and improve efficiency in the test, test brackets are usually used to support (such as figure 1 As shown, that is, multiple strings of hanging porcelain bottles are hung on the test bracket), and short-circuited with metal wires, and multiple strings of porcelain bottles are tested at the same time. In the previous pressure test of suspended porcelain bottles, the test bracket ...

AI Technical Summary

Problems solved by technology

[0003] The problems therein are: (1) poor safety and reliability: the traditional test wiring method is temporarily built at the work site, and the connection between each suspension porcelain bottle uses many wires, which are not standardized, and often fail due to the weak connection of the wires. Scattering, safe distance cannot be guaranteed and discharge phenomenon occurs

(2) Long time-consuming: It can be seen from the statistical summary of the suspension porcelain bottle pressure test work that the suspension porcelain bottle pressure test has a large workload and takes a long time; There are many wires, it is troublesome to replace the wiring, and because the wires are not in firm contact, multiple connections are required, etc., which takes a lot of time; the main factor affecting the test time is the long time to remove the wiring, followed by weak wiring or too close wire spacing The time spent on re-wiring is directly related to the rudimentary test wiring tools, so the rudimentary test wiring method is the key factor causing long working hours
