Research on Abnormal Heating Alarm Technology of Conductor Strain Clamp Based on Thermal Steady State Principle

With the continuous development of domestic power grid construction, coupled with the serious air pollution in some areas, the transmission line has been put into operation for a long time, resulting in the increasing phenomenon of abnormal heating of the tension clamp of the transmission line, which not only affects the safe operation and reliability of the power grid, but also restricts the improvement of the carrying capacity of the transmission line. Therefore, this paper studies the abnormal heating state of strain clamp in transmission line, and proposes an abnormal heating alarm technology of strain clamp based on online monitoring technology and thermal stability principle.
