Power transmission line lightning arrester

Abstract

The invention provides a lightning arrester of a power transmission line. The lightning arrester of the power transmission line comprises a lightning arrester, wherein a lightning stroke signal acquisition unit is arranged in a grounding loop of the lightning arrester in series, the lightning stroke signal acquisition unit comprises a current sensor, the current sensor is connected with an MCU through an integrator and an A / D signal converter, the MCU is connected with a lightning stroke signal detection unit, and the lightning stroke signal detection unit is connected with a signal receivingend. The lightning arrester of the power transmission line has the characteristics of long-distance wireless transmission, no maintenance, no need of battery replacement and the like, remote information transmission and monitoring of lightning counting of the power transmission line can be realized, tower climbing for checking a mechanical lightning counter is avoided, operation and maintenance efficiency of the power transmission line is greatly improved, labor intensity of operation and maintenance personnel of the power transmission line is greatly reduced, a large amount of manpower and material resources are saved, and operation and maintenance cost of the line is saved.

Description

technical field [0001] The invention relates to the technical field of lightning arresters, in particular to a transmission circuit lightning arrester. Background technique [0002] High-voltage transmission lines are the backbone grid of my country's power grid. Due to the high voltage level and long transmission distance, there are many places where transmission line towers are installed, the area is large, and the distance is long. The workload of line maintenance has greatly increased. Although the "Electricity Safety Operation Regulations" has made corresponding regulations on the safe operating environment, scope of activities, operating procedures and actions of the operators, in the actual inspection process, the operators are often unable to complete the tasks efficiently and comprehensively due to the heavy inspection tasks. Schedule inspections. Therefore, it is necessary to reduce the intensity of inspection work through technical means, improve the inspection e...

Problems solved by technology

[0005] Aiming at the technical problem that the current mechanical lightning counter and lightning arrester are installed on the line tower together, it is necessary for line inspectors to regularly check and record the number of lightning strikes marked by the counter, which consumes a lot of manpower and material resources and is very inconvenient. The present invention proposes a transmission circuit lightning arrester
