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
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

[0030] Discuss the specific implementation mode below in conjunction with accompanying drawing and embodiment

[0031] like Figure 1-3 , 1 is an infrared detection unit, 2 is a signal conversion transmission unit, 3 is a data analysis unit, 4 is a surge suppression device, 5 is a transmission line, 6 is a surge protector, 7 is a dedicated network or the Internet, and 9 is a transmission path.

[0032] The invention relates to a device capable of realizing online detection of a surge protector. The data analysis unit 3 establishes a relationship model between the infrared characteristic of the surge suppressing device of the surge protector, the magnitude and characteristics of the surge current, and the damage degree of the surge protector to realize the detection of the surge suppressing device of the surge protector. Infrared characteristics to judge the state of the surge current and the damage of the surge suppression device.

[0033] When a current flows through the su...

Abstract

The invention relates to an online detection device of a surge protective device, belonging to the field of lightning surge protection. The device comprises an infrared detection unit (1), a signal conversion and transmission unit (2) and a data analysis unit (3), wherein the receiving direction of the infrared detection unit (1) faces a surge suppressing device (4); the infrared detection unit (1) is connected with the signal conversion and transmission unit (2) by a transmission line (5); and the signal conversion and transmission unit (2) is connected with the data analysis unit (3). The device has high detection precision and is sensitive in reaction and realizes remote processing and network sharing of the detection information.

Description

technical field [0001] The invention belongs to the field of electric power equipment, and more specifically, belongs to the field of lightning surge protection equipment. technical background [0002] 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 the surge protector is ...
