In spring, as the temperature rises and humidity increases, the charge distribution in the atmosphere becomes more complex, and lightning activity gradually increases. Especially in some lightning-frequent areas, transmission lines are more vulnerable to the threat of lightning strikes. Lightning strikes may not only lead to line tripping and equipment damage, but also cause serious accidents such as fire, posing a serious threat to the safe and stable operation of the power grid.
Spring lightning hazard investigation is an important work of grid operation and maintenance, in order to improve the management efficiency of transmission line lightning arrester, to ensure the safe and stable operation of transmission lines in the thunderstorm season, our company gives Transmission line lightning arrester online monitoring device response program.
Core functions of transmission line surge arrester online monitoring device DX-WPS100-BL
1, real-time monitoring: real-time monitoring of lightning arrester leakage current, resistive current, the number of actions and time and other key parameters, so as to reflect the health of the lightning arrester;
2、Intelligent analysis and early warning: with data intelligent analysis function, through the system built-in AI algorithm, the monitoring data is automatically analyzed and compared with the historical data, once the abnormal situation is found, such as the leakage current exceeds the standard or the number of lightning arrester action is abnormal, the alarm will be raised immediately;
3、Wireless remote transmission: through GPRS/GSM and other wireless communication technologies, the monitoring data will be uploaded to the background in real time, the abnormal state automatically triggers an alarm, the operation and maintenance personnel can check the status of the equipment at any time through the background, say goodbye to manual climbing tower inspection.
4, self-powered: the use of lightning arrester itself leakage current power supply, without external power supply, while the use of intelligent SOC control, safety and energy saving, able to adapt to harsh environments, to ensure that the system runs reliably for a long time.
technical requirement
1. Withstand 4/10 μs inrush current: >100 kA
2, withstand 2ms square wave inrush current: >1000 A
3、Acting current：8/20μs inrush current 50A
4, lightning arrester warning leakage current: 1mA
Application effects
Transmission line surge arrester online monitoring deviceCan realize the leakage current, resistive current, and action number and time of multiple arrester arrester on the line intelligent perception, convenient operation and maintenance personnel to accurately and timely grasp of the state of the arrester. The application of the device can not only effectively avoid lightning arrester damage, failure, etc. caused by line lightning tripping accident, but also to solve the operation personnel need to daily to the scene for cumbersome transcription as well as the annual thunderstorm season before the charged detection workload. In addition, through the early monitoring and diagnosis of lightning arrester failure, can predict the life of the equipment, pre-judge the risk of failure, and improve the automation level of transmission line lightning arrester management.
