Tension lightning arrester protective cover

Abstract

The invention discloses a tension lightning arrester protective cover. The tension lightning arrester protective cover comprises a cover body with a hollow internal, an upper end part and a lower endpart of the cover body are a first cover body end part opening and a second cover body end part opening communicating with each other; a first holding part and a second holding part are arranged on the cover body; a side-cut opening is arranged at one side, opposite to the first holding part, on the cover body and from the first cover body end part opening and the second cover body end part opening; and seal connecting end plates are arranged at two sides of the side-cut opening. The tension lightning arrester protective cover disclosed by the invention is mainly used for a power transmissionand distribution electric system and used for protecting a discharge part on the tension lightning arrester, thereby playing effective protection effect on the discharge part on the tension lightningarrester; the discharge part between the discharge electrode on the tension lightning arrester and the connected connecting bolt and a lower electrode and the connected ball stud can be protected frombeing damaged by external severe environment, the effect of further protecting the lightning arrester is achieved, the fault rate is lowered, and the maintenance workload is reduced,

Description

technical field [0001] The invention belongs to the technical field of power transmission and distribution power equipment, and in particular relates to a shield for a tension arrester. Background technique [0002] With the continuous lengthening of power distribution network lines and the popularization of insulation design, the disconnection accidents caused by lightning damage are prominent, and the statistics of insulator breakdown accidents continue to rise, which has seriously threatened the safe operation of distribution network lines. Surge arrester is a protective device connected in parallel to electrical equipment. As a gap device artificially installed on the line or equipment, it is in an isolated and insulated state under normal operating voltage. Under overvoltage, the gap device is broken down and grounded to discharge and reduce voltage. , so as to protect the insulation of the line or equipment under overvoltage, which is sometimes called an overvoltage pr...

AI Technical Summary

Problems solved by technology

At present, the protective measures for the discharge part of the existing arrester are not in place, and no special protective measures are provided, which will easily cause the discharge part to be damaged by the external harsh environment, resulting in an increase in the failure rate of the arrester; therefore, it is urgent It is necessary to develop a protective device for the discharge part of the arrester
