Insulator dirt detecting method and device

Abstract

The invention belongs to the technical field of electric power insulating equipment detection, and particularly relates to an insulator dirt detecting method and device. The method comprises the steps that the relational expression among the antenna temperature, the environment temperature, the atmosphere humidity, the equivalent salt density and the equivalent dust density is established; the antenna temperature, the environment temperature and the atmosphere humidity are detected and substituted into the relational expression; double circulation increasing with the iterative step being eta 1 is carried out on the equivalent salt density and the equivalent dust density, and the minimum mean square error between the antenna temperature and the antenna temperature output through formula iteration is calculated; precise double circulation iteration with the iterative step being eta 1 / 10 is carried out, and when the error is minimal, the final equivalent salt density and the final equivalent dust density are obtained. The device comprises a microwave radiometer, a temperature sensor, a humidity sensor, a central processing unit, a memorizer, a display screen, operation buttons, a battery, a signal line and a power line. The insulator dirt degree is online detected in a non-contact mode, and the insulator dirt detecting method and device have the advantages of being high in precision, fast in detection, convenient to use and the like.

Description

technical field [0001] The invention belongs to the technical field of electric insulation equipment detection, and in particular relates to an insulator pollution detection method and device. Background technique [0002] In the power system, the pollution level of the insulators can be judged by detecting the pollution of the working insulators, so as to determine the time for cleaning the pollution, and reasonably arrange power outage maintenance. Timely and accurate determination of the pollution status of the insulators is of great help to reduce the impact of pollution flashover . Excessive insulator pollution testing will lead to frequent power outages and affect economic benefits, while too little testing may cause pollution flashovers, resulting in power outages, which in turn affect people's lives and business production. [0003] The artificial pollution detection methods currently used generally have the problems of complex equipment, cumbersome operation proced...
