Problems solved by technology

The problems of this method are: 1. The deterioration or damage of the surge suppression device may not generate enough energy to make the tripping device operate. At this time, the alarm unit cannot output the alarm.
2. The alarm signal may be output only when the device is damaged, which cannot be predicted in advance; the state during the damage process and the cause of the damage cannot be determined; 3. It is not suitable for signal surge protectors; 4. The energy and time of lightning current Analytical processing is not yet possible with dedicated equipment
Its defect is that the temperature switch cannot accurately and timely reflect the temperature change of the surge suppression device, so the temperature information that can be used for judgment is not sufficient and direct

Embodiment Construction

[0020] Discuss the specific implementation mode below in conjunction with accompanying drawing and embodiment

[0021] The surge protector is mainly composed of a surge suppression device (1), a photometric unit (2), a signal conversion and transmission unit (3), and a casing (4). When the surge suppression device (1) flows through the current, it will emit light , the photometric unit (2) installed on the surge suppression device (1) can detect the optical signal, and transmit the information to the signal conversion and transmission unit (3), the signal conversion and transmission unit (3) includes A / D conversion circuit and digital signal transmission circuit, the signal conversion and transmission unit (3) receives the signal output by the photometry unit (2), after signal conversion, transmits to the external device through the detection output terminal (5) on the casing (4). The signal conversion and transmission unit (3), the surge suppression device (1), and the photom...

Abstract

The invention relates to a surge protective device, belonging to the field of lightning protection. The surge protective device mainly comprises a surge suppressing device (1), a photometry unit (2), a signal conversion and transmission unit (3) and a shell (4), wherein the surge suppressing device (1) and the photometry unit (2) are installed in the shell (4); the photometry unit (2) is connected with the signal conversion and transmission unit (3); and the signal conversion and transmission unit (3) is connected to external equipment and can know the real-time state of the surge suppressing device (1). The device has wide application range and high reliability, is sensitive in detection, can detect the lightning surge flowing through the surge suppressing device (1) and deterioration or damage conditions of the surge suppressing device in real time so as to replace and maintain the surge suppressing device in advance and enhances the reliability of the equipment.

Description

technical field [0001] The invention belongs to the field of lightning surge protection equipment. technical background [0002] Lightning is a special weather phenomenon caused by the discharge of charged clouds in the air. Lightning is an important cause of damage to electronic equipment, and it threatens the security of electronic information systems in various fields such as construction, railways, civil aviation, communications, industrial control, and military affairs. Surge protectors are protective devices mainly used to suppress lightning surges. 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. At present, all regions and industries invest huge sums of money every year to purchase and install surge protectors in large quantities. But in essence, the surge protector is a device that "sacrifices oneself to protect others". When...
