Automatic alarm device for lightning protection

Abstract

The invention belongs to the technical field of power equipment, and particularly relates to an automatic alarm device for lightning protection. The device comprises a main bracket, an auxiliary bracket, a connecting piece and a trigger box body which are symmetrically arranged. The connecting piece is arranged at the upper ends of the main bracket and the auxiliary bracket and is connected with the main bracket and the auxiliary bracket; and the trigger box body is arranged on the outer side of the main bracket and the outer side of the auxiliary bracket and connected with the connecting piece, an electronic component and a loudspeaker which are electrically connected with the lightning arrester are arranged in the trigger box body, and the problems that after an existing lightning arrester is used for a long time, after an internal valve block is aged, the capacity of recovering a high resistance is lost, especially in an outdoor severe environment, after the lightning arrester is broken down by lightning stroke, maintenance personnel cannot accurately judge the specific installation position of the lightning arrester, and the maintenance and recovery time of electric appliances is seriously influenced are solved.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and in particular relates to an automatic alarm device for lightning protection. Background technique [0002] Lightning protectors, also known as lightning arresters, surge protectors, surge protectors, overvoltage protectors, etc., mainly include power supply lightning protectors and signal lightning protectors. Lightning protectors prevent lightning strikes through modern electricity and other technologies. damage to the equipment in it. The lightning energy absorption in the arrester is mainly zinc oxide varistor and gas discharge tube. [0003] Zinc oxide arresters are arresters with good protection performance. Utilizing the good nonlinear volt-ampere characteristics of zinc oxide, the current flowing through the arrester at normal working voltage is extremely small; when the overvoltage acts, the resistance drops sharply, and the energy of the overvoltage is released to achiev...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides an automatic alarm device for lightning protection, which is used to solve the problem of losing the ability to restore high resistance after the internal valve plate of the existing lightning arrester has been used for a long time. , especially in the harsh outdoor environment, the lightning strike will cause the lightning arrester to be broken down, causing maintenance personnel to be unable to accurately determine the specific installation location of the lightning arrester, which seriously affects the recovery time of electrical maintenance
