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.
At present, the physical quantity of the electromotive force generated by lightning surge has not been used in the detection data. It can be said that the state information of the surge protection device using the electrodynamic method is a blank

Abstract

The invention relates to a detection device of a surge protector, comprising pressure sensors, pressure deformation devices, detection circuits and a receiving device, wherein the pressure deformation devices are arranged between the pressure sensors and the surge protector to be detected; the detection circuits are arranged between the pressure sensors and the receiving device; and the pressure sensors acquire the information of the surge protector to be detected which is acquired by the pressure deformation devices and transmit the information to the receiving device via the detection circuits. The device is convenient to install, has high detection precision and sensitive response and can effectively reduce the fault points.

Description

technical field [0001] The invention relates to the field of electric power equipment, in particular to the field of lightning surge protection 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 damage includes short circuit (including freewhee...
