An automatic alarm device for lightning protection

Abstract

The invention belongs to the technical field of electric power equipment, and in particular relates to an automatic alarm device for lightning protection, which includes a symmetrically arranged main bracket, an auxiliary bracket, a connecting piece and a trigger box, and the connecting piece is arranged on the main bracket and the auxiliary bracket. The upper end of the trigger box is connected with the main support and the auxiliary support. The trigger box is arranged on the outside of the main support and the auxiliary support and connected with the connecting piece. The inside of the trigger box is provided with an electronic device electrically connected to the arrester. Components and loudspeakers, the present invention solves the problem that the existing lightning arrester loses the ability to restore high resistance after the internal valve plate ages after being used for a long time, especially in outdoor harsh environments, lightning strikes will cause the lightning arrester to be broken down, As a result, maintenance personnel cannot accurately determine the specific installation location of the arrester, which seriously affects the recovery time of electrical maintenance.

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...
