Abstract

The invention relates to the technical field of insulators, and in particular, relates to an insulator capable of adjusting a discharge gap, wherein the insulator comprises a steel cap, a ceramic piece, a steel pin, an upper electrode, a lower electrode and an insulating part; the steel cap is arranged at the top of the ceramic piece; the upper electrode is connected with the steel cap; the steel pin is arranged at the bottom of the ceramic piece; the lower electrode is connected with the steel pin, and the lower electrode is separated from the upper electrode by a certain distance; and the first end of the insulating part is in sliding connection with the upper electrode, and the second end of the insulating part is detachably connected with the lower electrode. The technical problem that the discharge gap is difficult to adjust 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 with an adjustable discharge gap. 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. During installation, according to different regions, different lines and different natural environments, the discharge gap must have different gap requirements. The existing ground wire insulators cannot adjust the discharge gap or it is difficult to adjust the discharge gap, and cannot meet the requirements of d...
