A New Shell Structure of Overvoltage Protector

Abstract

The invention discloses a novel overvoltage protector shell structure which includes a shell body and protective pads. The shell body includes an insulating layer, a heat insulation layer, a protective layer, and a light emitting layer. The insulating layer is made of double-layer epoxy resin. The protective layer includes a bumper pad and a metal net arranged on the surface of the bumper pad. A plurality of hole-shaped slots are arranged inside the bumper pad. A layer of waterproof film is arranged on the surface of the bumper pad. Raised blocks are arranged at the edge of the outer surface of the shell body. Each protective pad includes an arc section and a connecting section. A groove is arranged in the surface of each connecting section. The grooves and the raised blocks are clamped together. Each arc section wraps the corresponding connecting section, and the surfaces of the arc sections are polished. The device has good insulating and heat insulation performances, has a good surface buffering effect and a good anti-scratch role, is not easy to damage in transportation, and has a longer service life.

Description

technical field [0001] The invention relates to the technical field of power accessories, in particular to a novel shell structure of an overvoltage protector. Background technique [0002] When all electrical appliances are in use, it is best to avoid the grid voltage being too high or too low. Both industrial equipment and household appliances have a rated voltage, and the voltage range is usually specified as 170V-240V (you can see it on the nameplate or manual of the electrical equipment). If it exceeds this voltage, it will exceed the insulation strength and withstand voltage value of the electrical appliance, and the electrical appliance will heat up, break down, burn out or even catch fire. At present, due to the theft of neutral wires, equipment aging, technical failures, human failures, natural disasters, power outages, and power failures, etc., voltage instability, excessively high or low voltages have caused a large number of electrical appliances to be burned out...

AI Technical Summary

Problems solved by technology

At present, due to the theft of neutral wires, equipment aging, technical failures, human failures, natural disasters, power outages, and power failures, etc., voltage instability, excessively high or low voltages have caused a large number of electrical appliances to be burned out and burned out in large areas. People suffer heavy losses, there is no way to claim compensation, and things that waste people and money come one after another. Yimin overvoltage, overvoltage, and undervoltage protectors (also known as electrical protectors) should be added to prevent electrical fires and protect life and property; overvoltage Protectors are now widely used. When the overvoltage protector is in use or during handling, the surface and edges of the shell are easily damaged, which reduces the service life.
