Anti-thunder hard composite insulator with protective housing, electroscope ground ring and waterproof mechanism

Abstract

An anti-thunder hard composite insulator with a protective housing, an electroscope ground ring and a waterproof mechanism comprises an insulator body which is composed of an insulating rod and a plurality of composite rubber waterproof discs connected to the insulating rod. The insulating rod is composed of a metal core rod and an insulating layer arranged on the surface of the middle of the insulating rod, and the insulating layer of the insulating rod and the composite rubber waterproof discs are of an integrated structure; a jointing clamp is arranged at the top end of the insulator body;the side face of the jointing clamp is connected with the electroscope ground ring through a connecting arm; the jointing clamp and the joint of the electroscope ground ring and the jointing clamp areboth installed in the protective housing; the insulating layer and the composite rubber waterproof discs are made of a hard insulating material; and the insulating rod waterproof mechanism is arranged on the upper portion of the insulating rod. The anti-thunder hard composite insulator has the advantages that the insulating rod waterproof mechanism completely eradicates the possibility that waterenters the space between the top end of the insulating layer and the metal core rod to cause electricity leakage, and therefore the reliability of the insulator is improved; and the waterproof discsmade of the hard material effectively prevent the insulator from being pecked by birds, and therefore the service life of the insulator is prolonged.

Description

technical field [0001] The invention relates to an insulator, in particular to a lightning protection rigid composite insulator with a safety cover, an electrical inspection grounding ring and a waterproof mechanism, which is used for supporting power transmission lines. Background technique [0002] The insulating rod of the insulator used in the power transmission line is composed of a metal core rod and an insulating layer on the surface of the middle part, and the insulating layer is integrated with a composite rubber waterproof disc. The gap between the top of the insulating layer on the surface of the metal mandrel and the interface between the metal mandrel is prone to water ingress, resulting in a decrease in insulation performance and corrosion of the metal mandrel, posing a potential safety hazard. In addition, the rubber waterproof disk is often damaged by birds (such as crows), which affects the performance and service life of the insulator. Contents of the inv...
