Arc-proof stabbing gold tool for preventing aerial insulated wire being broken by lightning stroke

Abstract

The present invention provides an arc-tight puncture hardware fitting for preventing an overhead insulation wire from being damaged by lighting strike. The present invention includes an insulation layer for piercing the insulation wire, a piercing wire clip electrically contacting close to a conductor inside, a ground arc electrode electrically connected with the ground terminal of a line insulator, an arc-tight electrode electrically connected with the piercing wire clip, and an insulation cover without being sealed along the bottom. The present invention is characterized in that the arc-tight electrode electrically connected with the piercing wire clip adopts a two-way arc-tight electrode and is connected with the two sides of the piercing wire clip. Due to the two-way arc-tight electrode, the present invention alters defect of the original technology that the arc-tight puncture hardware fitting should be arranged on the load side in one-way use and on both sides of the insulator in two-way use. The present invention optimizes the shaped of the two-way arc-tight electrode into a dovetail structure or a vertical structure so as to make the operation of the arc-tight puncture hardware fitting safer, the installation more convenient and the use more economical under the two-way power supply mode. The arc-tight puncture hardware fitting provided with the present invention is convenient and quick to install, thus meeting the operational needs in the construction site.

Description

technical field [0001] The invention relates to an overhead power distribution line of a power system, in particular to an arc-resistant puncture fitting for preventing an overhead insulated wire from being broken by lightning, which is especially suitable for use on a 10KV overhead insulated wire. Background technique [0002] In order to reduce the failure of overhead distribution lines caused by external factors such as trees, birds, and snow, and improve the reliability of power supply, developed countries in the world have gradually adopted overhead insulated wires since the late 1960s. The power grid implements a pilot project of insulation transformation. In the 1990s, the promotion and application began. [0003] Compared with cables, insulated wires have obvious advantages of less investment and faster construction. However, the problem of lightning disconnection is very prominent. The principle of lightning disconnection of insulated wires is significantly diffe...

AI Technical Summary

Problems solved by technology

However, since the arc-resistant electrode set is a one-way arc-resistant electrode, it is only suitable for single-line installation

When facing double lines, the same protective fittings must be installed on both sides of the insulator, which not only causes the complexity of construction, but also causes too much waste of resources
