Problems solved by technology

[0004] However, the measurement technology using temperature and stress sensors in the prior art has poor spatial resolution and usually only provides the equivalent ice thickness measurement in a single file or even within the length of the tensile section, which has certain application limitations. The measurement results It is also not accurate enough, which is not conducive to accurate assessment of line risks by operation and maintenance personnel

Description

technical field [0001] Embodiments of the present invention relate to power electronics technology, and in particular to a system and method for measuring equivalent ice thickness. Background technique [0002] In the power system, the icing on the transmission line is one of the important factors affecting the operation of the line. The operation and maintenance department needs to grasp the icing situation of the line in time to take appropriate measures. If the severity of icing is known by manual measurement of simulated wires or on-site observation, there will be problems such as huge manpower consumption and environmental hazards. [0003] In the prior art, there are remote equivalent ice thickness measurement technologies based on distributed optical fiber temperature sensors or stress sensors. It has the advantages of wide measurement range, no labor consumption, and strong theoretical basis. [0004] However, the measurement technology using temperature and stress...
