Abstract

The invention provides an anti-thunder insulator used for a bare wire. The anti-thunder insulator is a novel anti-thunder insulator with a fault indicating function and applied to a 10KV overhead bare wire. Matching use of an insulator body and a fault indicator is adopted; the insulator body comprises a gap; in a use process, when thunder-strike overvoltage occurs, the gap between copper sheets in the insulator is switched on immediately only if the amplitude of the overvoltage endangers operational safety of a system, so that the overvoltage is released to the ground through resistor discs; therefore, large-area power failure or occurrence of secondary accidents of the system caused by burn down of the wire due to overvoltage arc establishment can be avoided, so that safety operation of the system can be ensured; the anti-thunder insulator is simple in structure, good in use effect, has the characteristics of high economical efficiency and practicability, and is suitable for popularization and application; and in addition, the anti-thunder insulator is safe and reliable, and capable of greatly reducing operating time and difficulty, saving precious time for fault removal of a power system in time, effectively reducing waste of resources, and saving limited space of a working plane.

Description

technical field

[0001] The invention relates to the technical field of power transmission and protection equipment, in particular to a lightning protection insulator for bare wires. Background technique

[0002] In overhead distribution lines, bare conductors play a pivotal role in power distribution operation and are an essential part. With the passage of time, the bare overhead conductors are exposed to the air for a long time, and the surface of the bare conductors is partially oxidized to form an oxide layer, which makes the bare conductors partially insulated. network, lightning strike disconnection accidents and line tripping caused by lightning strikes. Therefore, it is of great significance to speed up the research on measures to prevent insulator flashover, disconnection and tripping caused by lightning strikes on bare conductors to ensure the safe and reliable operation of distribution networks.
