Abstract

The invention relates to a power transmission lead wire temperature detection method, a power transmission lead wire maximum current carrying capacity detection method and a system thereof. Temperature values of different layers of an overhead power transmission lead wire can be accurately obtained under different current carrying capacities and meteorological conditions by detecting and calculating difference of the radial temperature of the overhead power transmission lead wire; the stability of safe operation of a power transmission line can be improved, the current carrying capacity of an overhead power transmission line is improved and the transmission capability of the overhead power transmission line is improved; the dynamic capacity increase of the power transmission lead wire can be achieved; in addition, an extra temperature measuring device does not need to be mounted on the power transmission line; the temperature of the whole power transmission lead wire can be monitored; the monitoring equipment investment is greatly reduced.

Description

Technical field [0001] The invention relates to the technical field of power transmission and distribution, in particular to a method and system for detecting the temperature of a transmission wire, and a method and system for detecting the maximum current carrying capacity of a transmission wire. Background technique [0002] With the continuous and rapid development of the national economy, the industrial and residential electricity consumption has increased sharply, and the problem of insufficient power transmission capacity of the grid at the peak of electricity consumption has become increasingly serious. Especially in the summer peak period of power consumption, some local power departments use power cuts to alleviate the problem of power supply and demand, which greatly affects people's daily life and industrial production. From the perspective of sustainable development and economics, in order to improve the transmission capacity of overhead transmission lines, in additio...
