Description

Technical field [0001] The invention relates to the technical field of lightning arrester remote monitoring, in particular to an intelligent transmission line lightning arrester action remote monitoring and precise positioning system. Background technique [0002] Overhead transmission lines are located in the wilderness, and the natural and geographical conditions are very complicated. Transmission lines and towers are prone to lightning strikes, which can cause large-scale power outages and cause major losses to the national economy and people’s lives. A reasonable lightning protection system design is to achieve prevention An important approach to mine disaster reduction: [0003] In actual operation, the gapless arrester counter will have resistive current passing under the operating voltage, and heat will be generated on the resistance valve slice, which will increase the temperature of the resistance valve slice. At the same time, due to the influence of environmental conditi...

AI Technical Summary

Problems solved by technology

[0003] In actual operation, a gapless arrester counter will have a resistive current passing under the operating voltage, and heat will be generated on the resistance valve plate, which will increase the temperature of the resistance valve plate. At the same time, due to the influence of environmental conditions, the valve plate of the arrester It will be affected by moisture and deteriorate, so that the resistive leakage current through the resistor sheet will increase under normal working conditions or the flashover voltage of the porcelain sleeve will decrease. Once an overvoltage occurs in the system, the current passing through the valve sheet in the arrester will increase rapidly, and The thermal capacity of the damaged valve plate is limited, which will cause thermal collapse of the arrester, and even cause the arrester to explode, so that the arrester loses its protective effect. Remotely monitor the number of actions of the arrester after being struck by lightning, and timely grasp the working status of the arrester after being struck by lightning. At the same time, accurately locate the line section where the arrester is struck by lightning to a certain tower, and understand the working status and action of the arrester in a timely manner.
