Intelligent protection module for surge protector

Abstract

The invention relates to an intelligent protection module for a surge protector, which mainly comprises a measurement and control unit (1) and a back-up protection unit (2). The measurement and control unit (1) and the back-up protection unit (2) are connected through a conducting wire and are arranged in the same shell (3). The intelligent protection module has the functions of acquiring, processing, controlling and communicating information of the surge protector. The measurement and control unit (1) can be set according to characteristic parameters of the surge protector and protected circuits to make the back-up protection unit (2) do controllable action. When the surge protector has short circuit, the back-up protection unit (2) acts to make the surge protector separated from the circuits in time and achieve the effect of short-circuit protection.

Description

technical field [0001] The invention relates to an intelligent protection module of a surge protector, which belongs to the technical field of surge protection for electronic and electrical equipment. technical background [0002] Lightning and the line surge caused by it and the line surge caused by other reasons are important reasons for the aging and damage of electrical and electronic equipment. Installing surge protectors on metal lines such as power lines, signal lines, and control lines connected to electronic equipment is one of the important measures for lightning protection. In this technical field, an important problem currently exists is that while the surge protector is protecting the equipment, its own components will gradually deteriorate until they are completely damaged, or they will be directly damaged under excessive surge impact, or cause The switch-type surge protection device produces freewheeling; for the power surge protector, its damage or cause dam...

AI Technical Summary

Problems solved by technology

In this technical field, an important problem currently exists is that while the surge protector is protecting the equipment, its own components will gradually deteriorate until they are completely damaged, or they will be directly damaged under excessive surge impact, or cause The switch-type surge protection device produces freewheeling; for the power surge protector, its damage or cause damage includes short circuit (including freewheeling, hereinafter omitted) and leakage current increase causing heating; for signal surge protector, The damage phenomenon is generally the increase of the impedance of the surge protector to signal transmission and the short circuit of the surge protector.

[0004] The above solutions still have the following problems: the selection of circuit breaker or fuse parameters conflicts with the requirements of power distribution protection, and cannot meet the requirements of selective coordination of power distribution protection

Obviously, because there is no better technical solution, it is helpless to generally use fuses or circuit breakers as the short-circuit protection of surge protectors in the surge protection industry.
