Novel horizontal-type high-voltage insulator protection device

Abstract

A novel horizontal-type high-voltage insulator protection device belongs to the field of high-voltage circuit protection and is used for solving the problem of arc generation by a high-voltage line insulator and large power transmission loss due to rainwater. The protection device comprises an upper half protection mechanism, a conical protection cover, and multiple groups of rain shading assemblies, wherein the upper half protection mechanism is used for protecting an upper half part, the front end and the rear end of an insulator, the conical protection cover is arranged at the root of the rear end of the insulator, a wire of the insulator is arranged in the conical protection cover, and the multiple groups of rain shading assemblies are arranged at the lower half part of the insulator and are used for protecting the lower half part of the insulator. By the protection device, the insulator can be effectively prevented from being in contact with rainwater, two poles of the insulator are protected from being moistened by rain, a blue arc discharge phenomenon at the root of the high-voltage line insulator is avoided, a high-voltage line insulator is prevented from being broken down, and a device fault is prevented. The protection device has the advantages of simplicity in structure, time and labor saving and long service lifetime, and is simple and convenient to install, the insulation capability of an important suspension point of a high-voltage line is stronger, thus, the fault frequency of high-level voltage running circuit is effectively reduced, and the operation time under high strength is reduced.

Description

technical field [0001] The invention belongs to the technical field of high-voltage line protection, and in particular relates to a new horizontal high-voltage insulator protection device. Background technique [0002] At present, most of the high-voltage lines in operation in the world are 220KVA and 66KVA. In rainy days, the surface between the two stages of high-voltage line insulators will be wet by rain, and the insulation effect is not obvious. At night, there will be weak blue arc discharge at the root of high-voltage line insulators, which is easy Insulators of high-voltage lines are broken down, causing equipment failure. Therefore, line inspectors need to conduct regular inspections, especially irresistible severe freezing rain will cause high-voltage wires to be blown by discharge arcs or iron towers to tilt. Once damaged high-voltage line insulators are found, they must be repaired. Replace it in time, otherwise it will cause immeasurable and serious losses. [...
