Lightning arrester online monitoring system

Monitoring significance

Metal oxide zinc arrester is a key equipment in power equipment. The resistive current on the arrester is an important indicator to measure the insulation level of the arrester. Real time online monitoring of the full current, resistive current, capacitive current, lightning strike frequency, and lightning strike time of the lightning arrester can achieve real-time monitoring of the insulation condition of high-voltage electrical equipment; At the same time, by analyzing monitoring data, potential faults of metal oxide zinc lightning arresters can be detected in a timely manner and important data basis can be provided for condition based maintenance, providing a strong and reliable guarantee for the safe, reliable, stable, and economical operation of the power system. Reliable equipment insulation information and scientific maintenance basis can be provided for operation and maintenance personnel, thereby reducing the occurrence of accidents, extending maintenance intervals, reducing the frequency and time of power outage maintenance, improving equipment utilization and overall economic benefits.

Lightning arrester online monitoring system

By adopting advanced hierarchical distributed structure, applying bus control technology and modular design principles, the anti-interference performance, measurement accuracy and stability of the system have been greatly improved, meeting the practical requirements of industrial sites. The expert diagnostic system of * is also used to scientifically analyze and diagnose the collected data, which facilitates timely and convenient understanding and mastery of the health status of substation equipment.

By monitoring the full current, resistive current, capacitive current, lightning strike frequency, and lightning strike time of the lightning arrester in real time, analyzing and fitting the monitored data, and combining it with the on-site working conditions, problems such as ceramic bushing leakage current or insulation rod leakage current increase caused by pollution or internal moisture of the lightning arrester can be detected in a timely manner to avoid accidents.
