[0002] In the power system, during the entire transmission process from power plants to power transmission and transformation equipment, and to end-user electrical appliances, there are a large number of variable temperatures that need to be detected and warned. The connection parts of high-voltage equipment such as bus connection points, various switches, For circuit breakers, main transformer bushing clamps, high-voltage cable joints, etc., due to climate change, material aging, corrosion, looseness, etc., it is easy to cause poor contact and increase contact resistance. High, resulting in overheating, causing insulation aging, resulting in breakdown and short circuit, easy to burn out the equipment, and even caused a fire and explosion of the equipment in serious cases. Dynamic tracking and monitoring of the operating status of these temperature rise fault points can not only prevent and eliminate such accidents It can also provide an important decision-making basis for power system safety and reliability analysis and scientific scheduling, which can improve the reliability of the energy system, ensure the continuity of power supply, shorten the time of fault power outages, and realize real-time monitoring of equipment status; therefore, providing An online monitoring device for electrical junction temperature based on wireless sensor network with high flexibility, fast and accurate monitoring is very necessary
