| Lightning arrester is one of the important power equipment in power system.Its function is to limit the overvoltage below a certain amplitude when the system is in crisis such as various types of overvoltages(generators,transformers,transformers,transformers,etc.).Ensure safe operation of power equipment.The protection of good characteristics,is widely used in the power grid,thermal damage,transient overvoltage impact factors of arrester internal moisture will lead to damage of arrester or explosion.Therefore,in order to ensure the safe operation of the power system of metal oxide arrester on-line monitoring in real time to understand the running state.Discover abnormal phenomenon of lightning arrester and accidents is very necessary.This paper is about the actual situation of Xingtai power supply company arrester online monitoring,for lack of measurement,adopt the analysis of two kinds of measurement methods of arrester online monitoring: the absolute and relative measurements to improve equipment reliability,reduce labor costs,ensure the safe and reliable operation of the equipment.Firstly,analysis principle and calculation method lightning arrester online monitoring,followed by the introduction of two ways of detecting arrester online monitoring.Again through data analysis,proposed to use two kinds of monitoring methods,and ultimately determine how to use two methods to improve equipment availability of service. |
