Abstract

This article presents the service life analysis of surge protection device that uses a Raspberry Pi to manage data for equipment in an intelligent ground monitoring system. The system analyzes and validates the service life of surge protection devices (SPDs) based on the number of lightning strikes and the magnitude of current flowing through them. The system uses RS485 format data transmission to store information on a cloud database and uses SCADA software to display the status of the equipment in the system. The system also uses AC Class II SPDs for AC power and SPD DC Class II for DC power to estimate the service life of SPDs, enabling planning of operation, maintenance and enhancement of lightning protection performance and reliability. The article presents an evaluation of the service life of a SPD by analyzing the results of the relationship between the number of times and the magnitude of current flowing through it and compares it with data obtained from the SPD test according to the IEC 61643-11 standard.
电涌保护装置寿命分析与监测
本文介绍了在智能地面监测系统中使用树莓派管理设备数据的浪涌保护装置的使用寿命分析。系统根据雷击次数和通过雷击的电流大小来分析和验证防雷器的使用寿命。系统采用RS485格式数据传输,将信息存储在云数据库中,并使用SCADA软件显示系统中设备的状态。交流电源采用交流II类防雷SPD,直流电源采用防雷DC II类防雷SPD,可预估防雷SPD的使用寿命,便于规划操作维护,提高防雷性能和可靠性。本文通过分析通过SPD的次数与电流大小的关系,对SPD的使用寿命进行了评价,并与根据IEC 61643-11标准进行的SPD试验数据进行了比较。
