Problems solved by technology

Therefore, when the electrode air gap becomes smaller, the insulation is not enough under ice-covered and rainy conditions, which affects normal power communication; when the electrode air gap becomes larger, the air gap cannot be effectively broken down by lightning strikes, and the safety of the transmission line cannot be protected.

Abstract

The invention discloses a ground wire composite insulator with an electrode positioning structure. Positioning pin holes are arranged on outer walls of two ends of a ground wire composite insulator hardware fitting. Two ends of the ground wire composite insulator hardware fitting are provided with electrode clamping hoops, and an inner side of each electrode clamping hoop is provided with a pin which is connected to and cooperated with the corresponding positioning pin hole. The pin of each electrode clamping hoop is inserted into each positioning pin hole of the composite insulator hardware fitting, and each electrode clamping hoop is fastened to an end portion of the composite insulator hardware fitting through a bolt and a nut. The ground wire composite insulator with the electrode positioning structure of the invention can ensure stability of an electrode air gap. The stability of power communication is ensured and a lightning stroke failure rate of a power transmission line is reduced.

Description

technical field [0001] The invention relates to a ground wire composite insulator, in particular to a ground wire composite insulator with an electrode positioning structure. Background technique [0002] Ground wire composite insulator is a kind of insulator used for insulation and lightning protection of communication lines on transmission lines. It is installed on the lightning protection line of transmission lines. The lightning protection line is also called ground wire, which is usually used for power communication. During normal operation, the insulator insulates the lightning conductor and the iron tower to ensure smooth power communication. When encountering a lightning strike, the lightning falls on the lightning protection line, and the lightning overvoltage breaks down the air gap between the two arcing electrodes on the ground wire insulator, and the strong lightning current is introduced into the earth through the iron tower, thereby protecting the normal opera...
