Introduction to the online temperature detection system of high-voltage switchgear of ZIGBEE technology High-voltage switchgear is a very important electrical equipment in the power system. Modern power systems have higher and higher requirements for power quality, and correspondingly, higher requirements for the reliability of high-voltage switchgear. With the development of the power grid and the improvement of equipment technology, 10, 35KV system switchgear has been widely used in the power grid. The internal overheating of the switchgear has become a common problem in the use of switchgear. Due to the airtightness of the switchgear body, in some areas with heavy loads, there is a problem of excessive temperature rise of the switchgear. Exceeding the temperature rise of the switchgear directly affects the safe and stable operation of the equipment. Moreover, the overheating problem is a constantly developing process. If it is not controlled, the degree of overheating will continue to increase, and it will have a great impact on the performance of the insulation parts and the life of the equipment. At present, for the switchgear used inside the power system, the equipment procurement procedures and technical policies are strictly followed to ensure that the switchgear connected to the network has passed the type test, especially the requirements for temperature rise are relatively strict. During operation, the load usually does not reach the full design capacity of the switchgear, and the temperature rise problem of the switchgear should not be very prominent, but the actual situation is not always the case. The actual temperature rise inside the switch cabinet, especially at the busbar connection and other locations, is usually always higher than the data measured in the type test.
