Abstract

The invention discloses a dynamic monitoring method for the lightning resistance level of a power transmission line tower. The method uses sensors to obtain parameters related to the lightning resistance level of the tower, and transmits the relevant parameters to the monitoring center through wired or wireless communication means. The monitoring center calculates the The real-time lightning resistance level of the transmission line is dynamically monitored and early-warned.

Description

technical field [0001] The invention relates to a dynamic monitoring method for the lightning resistance level of a power transmission line pole tower, which relates to the combination of data collection, data transmission and a line lightning resistance level model. Background technique [0002] At present, to solve the comprehensive lightning protection of power generation, transmission, transformation and distribution systems, in addition to adopting the current advanced lightning protection technology at home and abroad, reducing the grounding resistance of the grounding device at key points in the system can reduce lightning strike faults to a certain extent, but not completely Eliminate lightning strike failures. The invention establishes a relationship model between grounding resistance, soil water content and other factors and the lightning resistance level of the line, realizes dynamic monitoring of the lightning resistance level of the line, and timely finds towers...
