Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to a conductor temperature measurement method and device for a detachable cable connector. Background technique [0002] During the operation of the distribution network, poor electrical contact or overload and overload current heating will cause operating accidents, damage cable connectors, cables, and even burn connected electrical equipment, causing major losses. Separable connectors are commonly used components for electrical connection of power equipment. In the cable connection, they play the role of insulation, sealing, and equalizing the uneven electric field at the joint. For the electrical connection between power equipment and cables with a voltage level of 10kV-35kV, the high voltage breakdown resistance of the separable connector is required to be high. If the separable connector breaks down, it will affect the safe operation of the grid system, and even cause the ...
