technical field

The invention relates to the technical field of power transmission and distribution, in particular to a device and method for adjusting the position of a non-contact overvoltage monitor.

Background technique

my country implements the strategy of power transmission from west to east, and the power transmission system with UHV as the backbone transmits the power from the power center to the load center over a long distance and with a large capacity. In the process of power transmission, the higher the voltage level, the more prominent the contradiction between the safe operation of the line and the hazard of lightning. Online monitoring of transmission line overvoltage is of great significance for obtaining real transmission line overvoltage data, analyzing overvoltage accidents, improving grid insulation coordination, improving lightning protection measures for overhead lines, and ensuring safe operation of power systems.

Overvoltage detection is generally divided into two types: contact type and non-contact type. Contact monitoring is to install a capacitive voltage divider in the substation or on the line. Due to the high cost of installing a capacitive voltage divider and the increase in the workload of operation and maintenance, if an insulation fault occurs, it will increase the risk of system operation. Therefore, it is best to use non-contact monitoring for overvoltage monitoring of transmission lines. Existing non-contact overvoltage monitors are generally fixedly installed on poles and towers to accurately collect overvoltage signals of transmission lines by making the overvoltage monitoring sensor and transmission line diversion line reach the optimal monitoring angle.
