Abstract
The invention relates to the field of lightning protection, and discloses an on-line monitoring system for an arrester. The on-line monitoring system comprises an arrester on-line monitor installed in the field and monitoring and management analysis software of a monitoring center. The arrester online monitor is installed in the field, monitors the leakage current of an arrester in real time through a sampling sensor, and transmits to the monitoring center through an RS485 network. The monitoring center is responsible for receiving the real-time monitoring value of the arrester on-line monitor through the RS485 network to realize the functions of real-time display of arrester status parameters, historical data recording and contrast analysis, early warning and alarm, running status recording of the whole process, report printing and parameter setting. The invention realizes the unmanned on-line monitoring of zinc oxide arrester equipment of a substation, and judges the running safety status of the arrester more accurately and effectively by monitoring the resistive current or the whole current.
