Description

technical field [0001] The invention relates to the technical field of thermistors, in particular to a polymer material for a ring network governance control device and a preparation method thereof. Background technique [0002] With the development of the power grid and the improvement of equipment technology, the ring network governance control device has been widely used in the power grid. Due to the abnormal temperature and humidity in the long-term operation of the ring network control device, it is very easy to cause potential safety hazards, thereby destroying the safe and reliable operation of the power grid. Therefore, it is very necessary to implement long-term effective monitoring for the temperature and humidity status and fault status of the ring network management control device, and timely alarm and rapid management and protection of abnormal conditions. In order to play the role of overcurrent or overtemperature protection, the use of polymer materials for r...
