[0002] With the continuous development of the power system, the low-voltage distribution control box plays a vital role in power distribution. However, due to long-term operation and high ambient temperature, the low-voltage distribution control box is prone to overheating, affecting its normal operation and even causing safety accidents. At present, a temperature detector is installed inside the low-voltage distribution control box, which can monitor the temperature inside the control box in real time and issue an early warning when the temperature exceeds the preset threshold.
