Abstract

The invention relates to the technical field of insulators, and in particular, relates to an insulator which comprises an insulator body, an upper electrode and a lower electrode; the insulator body comprises a steel cap, a ceramic piece and a steel pin; the steel cap is arranged at the top of the ceramic piece, and the steel cap is provided with a mounting plate; the upper electrode and the mounting plate are connected through a first bolt and a first nut; the first bolt is sleeved with a limiting sleeve piece; the limiting sleeve piece is arranged between the mounting plate and the upper electrode in an abutting manner; the steel pin is arranged at the bottom of the ceramic piece; and the lower electrode is connected with the steel pin, and the lower electrode and the upper electrode are spaced by a certain distance. According to the invention, the technical problem that the consistency of discharge gaps of a whole line cannot be ensured due to the difference of installation habits and operation errors of different personnel in the prior art is effectively solved.

Description

technical field [0001] The present application relates to the technical field of insulators, in particular to an insulator. Background technique [0002] The ground wire insulator is used to support the ground wire in the overhead line. When the line is in normal operation, the ground wire is insulated from the ground terminal; when the ground wire is struck by lightning and the voltage exceeds the specified value, the gap discharges, and the ground wire conducts with the ground terminal through the gap. , It plays a vital role in ensuring the normal operation of overhead transmission lines and providing high-quality power services. However, at present, the discharge gap distance of the ground wire insulator is quite different due to the installation habits and operation errors of different personnel, that is, it is difficult to ensure the consistency of the discharge gap of the entire line after the installation is completed; During the process, due to wind swing, vibratio...
