[0002] The development of the power system will be towards high voltage and large capacity. The transmission capacity of the equipment will continue to increase, and the problem of temperature rise of electrical equipment that troubles the operation of power plants will become more prominent. Due to the limited means of fault testing of high-voltage electrical equipment, it is more difficult to find the temperature exceeding the limit in the switch box and the closed bus. As the temperature rise time increases, the temperature exceeding the limit will increase the degree of oxidation due to heat, which may cause major accidents such as burning of the busbar, contact, contact plate damage, power outage, etc.

[0003] Existing electrical contact temperature monitoring equipment, such as wireless temperature sensors, usually use tape to fix the sensor probe on the circuit breaker contact when using the temperature sensor to measure the temperature of the circuit breaker contact. Therefore, when the probe is subsequently inspected, it takes time to untie the tape before it can be inspected.

[0004] Therefore, it is necessary to provide a new high-voltage self-collecting electric contact temperature measuring device to solve the above-mentioned technical problems. Utility Model Content
