Chinese Professional Secondary Surge Arrester - Intelligent Surge – Leihao

Surge protective device, suitable for 50 / 60Hz AC, rated voltage of 220 V to 380 V power supply system, for indirect lightning and direct lightning impact or other transient overvoltage surge protection, suitable for family residential, tertiary industry and industrial field surge protection requirements.

Intelligent Surge

There is no uniform definition of intelligent SPD at home and abroad, but the concept of intelligent SPD has been recognized by R&D designers and users in practice. Intelligent SPD should have the following four basic characteristics:
① Surge protection function and safety performance;
② Monitoring function of operating parameters;
③ Fault alarm and failure prediction function;
④ Communication and networking functions.

Intelligent SPD realizes lightning current monitoring, which can monitor parameters such as lightning peak current and lightning times of tower in real time.

With the organic combination of intelligent surge protector and NB-IoT wireless module, many problems in substation intelligent lightning monitoring will be solved easily.

With the development of smart cities, the wide application of new technologies such as Internet of Things, cloud computing and the next generation Internet, intelligent SPD based on NB-IoT technology is increasingly becoming an important weapon for the communication industry to ensure the security of network operation. Monitoring, controlling and managing the lightning protection system of communication stations will be the only way to improve the management level of communication networks. The application research of NB-IoT will strongly promote the industry innovation of intelligent surge protector and promote the progress of new technology.
