[0002] With the continuous development of the national economy and the increasing electricity consumption, low-voltage cabinets are becoming increasingly widely used. Since most electrical equipment and appliances are inductive loads, the grid not only supplies active power to the loads but also transmits reactive power. This reactive power increases line voltage drop, increases line losses, and reduces transformer output. Therefore, most domestic JP cabinets, distribution boxes, and low-voltage switchgear products require comprehensive functionality, one of which is reactive power compensation. To reduce line losses and increase transformer load capacity, cabinets generally include reactive power compensation.

[0003] Low-voltage reactive power compensation equipment primarily includes shunt capacitors and reactive power compensation controllers. Shunt capacitors are the primary reactive power compensation device, automatically adjusting their capacity based on system changes. Reactive power compensation controllers control the shunt capacitors, ensuring the system always operates at optimal reactive power levels.

[0004] At present, when the low-voltage reactive power control device is installed in a cabinet and in use, it has poor confidentiality and weak anti-interference ability, and is unable to detect the real-time temperature of the low-voltage reactive power control device in the cabinet, resulting in the inability to control the safe operating temperature of the low-voltage reactive power control device, and thus there is a risk of burning. Therefore, a new type of low-voltage reactive power control device is needed to improve the above problems. Utility Model Content

The filter 106 is connected to the circuit. According to the frequency difference between the signal and the interference signal, filters 106 with different performances can be used to suppress the interference signal and improve modularity. The filtering emitted by the filter 106 is an operation to filter out the frequency of a specific band in the signal, which can suppress and prevent the influence of the interference signal on the low-voltage reactive control device.

[0029] Among them, a working indicator light 202 is fixedly connected to the side of the thermostat 201, and a physical button 205 is provided on the side of the thermostat 201, and there are several physical buttons 205.
