The development trend of lightning protection products and how to realize smart lightning protection in DL/T5408-2019 power plant and substation electronic information system 220/380V power supply surge protection configuration, installation and acceptance procedures, clarifying the installation in the PC section and MCC section Secondary surge protector, and has specific requirements for its parameters as follows:

With the development of the industry and market demand of surge protectors, from the perspective of product application, SPD has shown a trend of scene application customization and product size miniaturization; now and in the future, SPD is rapidly developing in the direction of intelligence, from faults From trip remote signaling, lightning counting, peak detection, waveform restoration, life prediction, grounding grid resistance monitoring, lightning warning, etc., lightning protection products are being integrated into the booming digital wave lightning protection terminals and smart lightning protection systems. , The intelligent lightning protection system is mainly composed of three parts: the equipment layer, the communication layer and the application layer. Based on electronic technology, network technology, information management technology, etc., it has the functions of remote monitoring and failure alarming of the working status of the lightning protection device. ——Quoted from "T/SLPA 000002.1-2021" (Lightning Protection Intelligent Online Monitoring System Part 1: General Provisions). The intelligent lightning protection system consists of three subsystems: lightning early warning system, lightning protection monitoring system and grounding resistance monitoring system. real-time monitoring. It can conduct in-depth analysis of the characteristics of lightning hazards in different regions and different industries, and then take corresponding protective measures to achieve economical and effective overall protection effects.

The intelligent lightning protection system developed by Anhui Jinli can use the Internet of Things technology to send the information (the amplitude of lightning current, the time and number of lightning strikes, the path of intrusion, the root cause of damage, etc.) The wireless communication method transmits the monitored information data to the monitoring center cloud platform. Then, the information is processed using algorithm simulation, big data mining analysis and other technologies. The user obtains the corresponding sound and light alarm information from the monitoring center through human-computer interaction, which provides a guarantee for the rapid implementation of protection and maintenance, so as to achieve an economical and effective overall protection effect.
