Description
Technical field [0001] The invention relates to a low-voltage power distribution cabinet in a power supply system, in particular to a low-voltage power distribution cabinet fire alarm protection device and a temperature detection method with reliable work, high intelligence and long service life. Background technique [0002] As we all know, low-voltage power distribution cabinets are commonly used low-voltage power distribution equipment in power supply systems. During use, they are mainly for accidents such as overload, short circuit, leakage, and aging caused by fires. At present, whether in the market or in the existing In the publication technology of the literature, some devices with alarm function are more or less recorded, but these devices do not have protective functions, especially they do not have the functions of intelligent power-off and intelligent fire extinguishing, resulting in fires that cannot be controlled and eliminated in time. This leads to casualties and ...
