[0002] The high-voltage circuit breaker refers to a high-voltage electrical appliance used for cutting off or connecting a load or a fault circuit with a rated voltage of 3kV or above. The high-voltage circuit breaker may generate heat at the contact arm and other connecting parts due to reasons such as oxidation, dirt, aging of the equipment, and poor contact between the moving and static contacts. At present, power maintenance personnel usually install temperature sensors on the surface of the high-voltage circuit breaker contact arm to monitor the temperature in real time.

[0003] The prior art discloses a high-voltage circuit breaker temperature measuring device (authorized publication number CN220819244U), and the annular fastener further includes an upper annular plate and a lower annular plate.
