Wet power frequency rain test device of composite insulator

Abstract

The invention relates to a wet power frequency rain test device of a composite insulator. The wet power frequency rain test device comprises: a rain unit, wherein the rain unit comprises a rain base,a vertically arranged rain rod is installed on the rain base, a spray nozzle is further installed on the rain rod, and the tail end of the spray nozzle is connected with a rain test box through a spray hose; and a supporting unit disposed beside the rain unit, wherein the supporting unit comprises a supporting base, a pair of vertically arranged insulator supporting columns is installed at the upper end of the supporting base, a supporting flange is further connected to the top end of each insulator supporting column, the two supporting flanges cooperate to realize the supporting of a composite insulator to be tested, and a pair of limiting bolts is further installed at the top ends of adjacent sides of the two supporting flanges. The wet power frequency rain test device provided by the invention has the advantages that, by using the cooperation between the rain unit and the supporting unit, a rainfall weather can be well simulated, and the composite insulator is under the rain, so that the performance of the composite insulator after the rain can be conveniently detected.

Description

Technical field [0001] The invention relates to the field of composite insulator testing, in particular to a wet power frequency rain test device for composite insulators. Background technique [0002] As a new generation of insulator products, composite insulators usually consist of a core rod, a silicone sheath wrapped around the core rod, an umbrella group, and hardware at both ends. Composite insulators are a special insulation control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used for telegraph poles. With the development of science and technology, a lot of disk-shaped insulators are hung on one end of the high-voltage wire connection tower. It is used to increase the creepage distance. It is usually made of glass or ceramic. Called an insulator. Insulators play two basic roles in overhead transmission lines, namely supporting wires and preventing current from returning to the ground. These two roles must be ...
