With the gradual development of smart grids, the requirements for the safe operation of power systems are becoming increasingly high. Low and high voltage distribution panels are important electrical equipment that make up smart grids, but during operation, abnormal phenomena such as joint heating and partial discharge of internal devices often occur, which can lead to accidents in severe cases. Currently, online temperature monitoring of distribution panels, partial discharge monitoring technology, and very early fire warning technology are widely used in the construction of smart grids.
