Novel detection device for protector for surge

Abstract

The invention relates to a novel detection device of a surge protector, which utilizes the nature of temperature switch action when the temperature changes for carrying out the state detection of a surge suppressor by utilizing the reaction of a temperature switch group to the temperature change of the surge suppressor, thus replacing a common mode of adopting a trip device to drive a microswitchfor carrying out alarming. The novel detection device of the surge protector mainly consists of the temperature switch group (2), an alarming terminal (3) and the like. The device can carry out detection alarming to the real-time state of the surge suppressor, namely, when a thunder stroke occurs to or a fault current passes through the surge suppressor, the novel detection device carries out real-time state detection, can detects the source and the magnitude of the current as well as the damaged condition of the devices by establishing a model for analyzing fault reasons, has strong recoverability, can carry out repeated detection and can realize detection alarming by circuits.

Description

technical field [0001] The invention relates to a novel detection device of a surge protector. Background technique [0002] 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 the surge protector directly affects its lightning protection effect, and brings hidden dangers to the safety of the protected equipment. This requires the protection of surge protectors. Routine maintenance of surge protectors, that is, real-time detection of the status of surge prote...

AI Technical Summary

Problems solved by technology

The problems of adopting 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 one parameter, but the state in the damage process 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. 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 generate enough energy to make the tripping device operate, and the alarm unit cannot perform alarm output

4. The energy and time of the lightning current cannot be analyzed through the output signal of the alarm unit
