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

[0029] Discuss the specific implementation mode below in conjunction with accompanying drawing and embodiment

[0030] Such as Figure 1-3 , 1 is the temperature measurement unit, 2 is the signal conversion transmission unit, 3 is the data analysis unit, 4 is the surge suppression device, 5 is the transmission line, 6 is the surge protector, 7 is the private network or the Internet, and 9 is the transmission path .

[0031] The invention relates to a device capable of realizing online detection of a surge protector. The data analysis unit 3 establishes the relationship model between the temperature-time curve of the surge suppressor device of the surge protector, the magnitude and characteristics of the surge current, and the damage degree of the surge protector, and detects the surge suppressor device of the surge protector. The temperature-time curve can be used to judge the state of the surge current and the damage degree of the surge suppression device.

Abstract

The invention relates to a device belonging to the lightning protection field, which comprises a temperature measuring device (1), a signal conversion transmission unit (2) and a data analysis unit (3). The temperature measuring device (1) is mounted on or outside to a surge suppressor (4) and is connected with the signal conversion transmission unit (2) through a transmission line (5), and the signal conversion transmission unit (2) is connected with the data analysis unit (3). The invention has the advantages of high detection precision and sensitive reaction, and can realize network sharing of remote information handling and inspection.

Description

technical field [0001] The invention belongs to the field of lightning surge protection in the field of electrical and electronic 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 subjected to lightning surge cu...
