Low-voltage power distribution cabinet fire alarm protection device and temperature detection method

Abstract

The invention relates to a low-voltage power distribution cabinet fire alarm protection device and a temperature detection method. The low-voltage power distribution cabinet fire alarm protection device comprises a cabinet body, a control box, a cabinet door, a light alarm, a sound alarm, a support, a fire extinguishing device, a temperature sensor and a central processor. The low-voltage power distribution cabinet fire alarm protection device is characterized in that the cabinet door is installed on the cabinet body through a door shaft; the top part of the cabinet body is provided with bus holes; the cabinet body is internally provided with a plurality of partition space structures formed by spacing boards, and each partition space structure is internally provided with a smog sensor, a contactor, a mounting frame and a connector; the cabinet body is further internally provided with mounting boards, and the mounting frame is installed on the mounting boards; and a power supply input wire and a power supply output wire are respectively connected with an input end and an output end of the contactor. The low-voltage power distribution cabinet fire alarm protection device is capable of realizing the purposes of intelligent temperature detection, intelligent fire detection, intelligent power cutting and intelligent fire extinguishing, the service lifetime of a low-voltage power distribution cabinet is prolonged, a fire is avoided, the application of the low-voltage power distribution cabinet is wider, and the low-voltage power distribution cabinet fire alarm protection device is suitable for market popularization and is good in economic benefit.

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 temperature detection method with reliable operation, 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 aimed at accidents such as overload, short circuit, leakage, and aging. In the disclosed technologies of the literature, some devices with alarm functions are more or less recorded, but these devices do not have protective functions, especially do not have the functions of intelligent power-off and intelligent fire extinguishing, resulting in fires that cannot be controlled and eliminated in time. resulting in personal injury and property damage. [0003] Through search and comparison...
