[0001] The utility model relates to the technical field of temperature control alarm, in particular to a temperature control alarm device for preventing unit temperature from jumping. Background Art

[0002] High-voltage distribution cabinet refers to an electrical product with a voltage level of 3.6kV to 550kV, which plays the role of switching, controlling or protecting in power generation, transmission, distribution, power conversion and consumption of power systems. It mainly includes high-voltage circuit breakers, high-voltage disconnectors and earthing switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and high-voltage switch cabinets.

[0003] Most high-voltage distribution cabinet units need to monitor temperature. After the monitoring instruments are installed in the cabinet units, the temperature monitoring instruments of the units are inconvenient to remove and maintain due to the installation location and long-term use, which may cause changes in the monitoring data. Therefore, they need to be improved. In addition, the connecting wires are at the rear end of the unit and may be accidentally touched and broken, so they also need to be processed.
