Fire monitoring and fire extinguishing system of electrical cabinet

Abstract

The invention discloses a fire monitoring and fire extinguishing system of an electrical cabinet. The fire monitoring and fire extinguishing system comprises a fire detection system for detecting fireinformation in the electrical cabinet; a fire extinguishing alarm controller used for receiving the fire information sent by the fire detection system; a fire extinguishing device, which includes anaerosol fire extinguishing device and an alarm, and is used for carrying out fire extinguishing and alarming by receiving a control signal sent by a fire extinguishing alarm controller according to the fire information; and a master control system used for receiving environmental information and alarm information in the electrical cabinet sent by the fire extinguishing alarm controller, and informing relevant personnel of giving an alarm. According to the fire monitoring and fire extinguishing system of the electrical cabinet provided by the invention, a smoke sensor, a temperature sensing sensor, a flame detector and a temperature sensing cable are used for detecting the fire in the electrical cabinet; an S-shaped aerosol automatic fire extinguishing device is adopted, which has the advantages of chemical and physical fire extinguishing modes, and the advantages of being high in fire extinguishing efficiency, low in toxicity, small in size, no pollution to the environment and the like, only needs to be stored under normal pressure, and simple in construction and maintenance.

Description

technical field [0001] The invention relates to the field of electrical fire fighting, in particular to a fire monitoring and fire extinguishing system for an electrical cabinet. Background technique [0002] The safety and reliability of the power supply system in coal mine production are very high. Once a fire occurs in the electrical cabinet or power supply cable, it will cause great safety hazards to the personnel or equipment in the mine, and large-scale accidents such as property loss or casualties will inevitably occur. , Therefore, the requirements for the fire extinguishing system are very high. [0003] Mine substation mainly includes substation and cable trench. At present, water spray fire extinguishing system, traditional gas fire extinguishing system and mobile fire extinguishing system are mainly used. These fire extinguishing systems cannot meet the fire extinguishing requirements of fire extinguishing room and cable room, and mine The substation room is com...
