Abstract

The invention provides an insulator pollution flashover monitoring device and method. A photoelectric detector senses an ultraviolet analog signal and a blue light analog signal on an ultraviolet optical filter and a blue light optical filter respectively and sends the ultraviolet analog signal and the blue light analog signal to a main control circuit board; a signal acquisition unit in the maincontrol circuit board performs analog-to-digital conversion on an input ultraviolet analog signal and an input blue light analog signal to obtain a digital signal, and the digital signal is sent to asignal transmitting unit through a sending unit in the main control circuit board and sent to a background through the signal transmitting unit; and the background monitors a pollution flashover condition of the insulator at night according to the digital signal. Compared with the prior art, by using the technical scheme of the invention, the defects of manual regular inspection and inaccurate monitoring parameters can be avoided, the working efficiency is greatly improved, the labor intensity is reduced, comprehensive and real-time online monitoring is achieved, the monitoring cost is reduced, and the monitoring timeliness is improved.

Description

technical field [0001] The invention relates to the technical field of transmission line monitoring, in particular to an insulator pollution flashover monitoring device and method. Background technique [0002] With the rapid development of my country's economy, electricity has become an indispensable part of daily life and industrial production. In order to meet the growing demand for electricity, the total length of transmission lines and the span of power transmission are also increasing. Insulators on transmission towers, as a special insulation control, can play an important role in overhead transmission lines. [0003] However, due to the wide area of ​​transmission lines and complex geographical conditions, the number of tripping accidents of transmission lines caused by lightning strikes, heavy fog, and pollution flashovers is also increasing; among them, tower pollution flashovers, as one of the main accidents of transmission lines, have great impact on power system...
