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

[0033] Discuss the specific implementation mode below in conjunction with accompanying drawing and embodiment

[0034] refer to Figure 1-3 As shown, 1 is the photometry unit, 2 is the signal conversion and transmission unit, 3 is the data analysis unit, 4 is the surge suppression device, 5 is the transmission line, 6 is the surge protector shell, 7 is the light emitting device, and 8 is the dedicated A network or the Internet, 9 is a transmission path, and 10 is an energy coupling unit.

[0035] Install the surge suppression device (4) and photometry unit (1) in the surge protector shell. When a lightning surge current passes through the surge suppression device (4), the light-emitting device connected in series with the surge suppression device or through the energy coupling unit will emit light, which can be easily detected by the photometry unit, and the signal passes through The signal conversion and transmission unit (2) transmits it to the data analysis unit (3), and ...

Abstract

The invention relates to a detection device in the field of lightning surge protection. The device comprises a photometry unit (1), a signal conversion and transmission unit (2) and a data analysis unit (3). A surge protective device comprises a surge suppressing device (4) and a light-emitting device (7). The photometry unit (1) is installed in the irradiation range of the light-emitting device (7). The photometry unit (1) is connected with the signal conversion and transmission unit (2) by a transmission line (5). 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 devices. 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 ...
