Problems solved by technology

The advantage of the simulated wire method is that the principle is relatively simple and easy to operate, but there are some problems in the simulated wire measurement method. First, the ice thickness measured on the simulated wire is usually different from the ice thickness on the actual running wire; During the ice work, the icing on the simulated wire cannot be removed at the same time, resulting in the failure of the wire icing monitoring function

Abstract

The invention relates to an OPGW icing thickness measuring method and a measuring device thereof. The method comprises the following steps: (1) monitoring icing condition of OPGW ground lines in a real-time manner; (2) when the thickness of the ice on the OPGW ground lines is beyond the alert thickness, de-icing alert information is sent out; (3) establishing a de-icing circuit according to the de-icing alert information; (4) carrying out de-icing operation according to the de-icing circuit; (5) monitoring and collecting de-icing temperature and progress of the OPGW ground lines; and (6) when the icing fall-off degree of the OPGW ground lines meets the requirements, de-icing operation is stopped. The technical proposal of the method and the device provided by the invention enables icing continuous measurement of the OPGW.

Description

[0001] Technical field: [0002] The invention relates to the technical field of on-line monitoring of electric power system transmission and transformation, and more particularly relates to a method for measuring the thickness of an OPGW ice coating and a measuring device thereof. [0003] Background technique: [0004] At present, the icing monitoring of transmission lines mainly relies on manual inspection. The areas where high-voltage and ultra-high-voltage transmission lines are distributed have complex terrain and harsh environments, making line inspection work very difficult. Restricted by factors such as sensor technology, communication technology, power supply and anti-interference technology, the development of online ice monitoring technology is very slow. At home and abroad, the weather station for automatic detection of ice and snow on conductors, the automatic detection and forecasting system for ice and snow on conductors, the load measurement and data acquisitio...
