Brand-new detector for surge protector

Abstract

The invention relates to a brand-new detector for a surge protector, which is characterized in that: a photosensitive device (2) builds a model and analyzes optical energy signals through the acquired optical energy signals (namely the optical energy signals emitted by a surge suppression device unit (1) when a lightning stroke current flows through) to acquire energy of the lightning stroke current and the state of the surge suppression device unit (1) per se. The device mainly comprises the surge suppression device unit (1), the photosensitive device (2) and an alarm terminal (3). The detector provides a simple and reliable detection scheme for detection and alarm of the surge protector. The detector has the advantages of repeated use and long service life.

Description

technical field [0001] The invention relates to a brand-new detection device of a surge protector. technical background [0002] Lightning is a special weather phenomenon caused by the discharge of cloud in the air. Lightning is an important cause of damage to electronic equipment, which threatens the safe and stable operation of electronic information systems in various fields such as construction, railways, civil aviation, communications, industrial control, and military. 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. Surge protectors have been widely used in various fields and play an important role in lightning protection. The quality of its state directly affects its lightning protection effect, thus bringing hidden dangers to the safety of the protected equipment. Therefore, it is very important to detect and alarm the state o...

AI Technical Summary

Problems solved by technology

The problems of taking the above measures are: 1. The alarm unit can only detect the good and bad states of the surge suppression device, and can only output a kind of parameter, but the state in the process of damage and the cause of the damage are all different. Not sure; 2. The alarm unit is driven by the tripping device in the surge protector, and the alarm signal can only be output when the device is damaged, and it cannot be restored, and the alarm cannot be repeatedly detected; 3. The deterioration of the surge suppression device may not necessarily cause group damage The energy that makes the tripping device act, the alarm unit cannot output an alarm; 4. The energy and time of the lightning current cannot be analyzed through the output signal of the alarm unit
