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 completely 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 of lightning current and time cannot be analyzed and processed by special 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

specific Embodiment approach

[0031] Describe specific implementation below in conjunction with accompanying drawing and embodiment theory

[0032] refer to Figure 1-3 As shown, 1 is the magnetic induction 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 loop, and 8 is the private network or Internet, 9 is a transmission path.

[0033] The online detection device of the surge protector of the present invention includes a magnetic induction unit (1), a signal conversion transmission unit (2) and a data analysis unit (3), the magnetic induction unit (1) and the surge suppression device (4 ) is installed close to the loop, the magnetic induction unit (1) is connected to the signal conversion and transmission unit (2) through the transmission line (5), and the signal conversion and transmission unit (2) is connected to the data analysis unit (3).

[0034] The signal con...

Embodiment approach

[0038]There is another embodiment: the transmission form between the signal conversion transmission unit (2) and the data analysis unit (3) is not limited to the bus form, according to the actual situation, it can also be transmitted in a multi-wire mode, and it is particularly emphasized that: two They can also be connected through the network, that is, the converted digital signal is transmitted to any computer that can be connected to the network through the network. The digital signal can not only be collected in time, but also can be analyzed and processed by the computer running software. The results are obtained, thereby realizing remote information processing and sharing.

[0039] Not only that, the present invention can realize that a signal conversion and transmission unit (2) can simultaneously process the information sent by a plurality of magnetic induction units (1), which helps to improve the efficiency of signal conversion and transmission; and a data analysis u...

The online detection device of the SPD comprises a magnetic induction unit (1), a signal conversion and transmission unit (2) and a data analysis unit (3), wherein the magnetic induction unit (1) is mounted close to a loop (7) of a surge suppression device (4), and the signal conversion and transmission unit (2) is connected with the magnetic induction unit (1) through a transmission line (5) and also connected with the data analysis unit (3). The invention has the advantages of high detection accuracy and sensitive reaction and realizes remote processing and network sharing of detection information.

Description

technical field [0001] The invention 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 protector is a device that "sacrifices oneself to protect others". When t...
