Automatic fire extinguishing system and fire extinguishing method for electrical cabinet of railway vehicle

Abstract

An automatic fire extinguishing system for an electrical cabinet of a railway vehicle is mainly formed by sequentially connecting high-pressure water mist equipment, smoke and fire alarm equipment anddata processing equipment. The smoke and fire alarm equipment detects the smoke and fire condition in the electrical cabinet in real time and sends data to the data processing equipment. The data processing equipment receives the data sent by the smoke and fire alarm equipment, whether a fire disaster happens in the electrical cabinet or not is judged, meanwhile, when a fire disaster happens, thehigh-pressure water mist equipment is started to achieve automatic fire extinguishing, the high-pressure water mist equipment sprays high-pressure water mist when the fire disaster happens, and the fire disaster of electrical elements and cables in the electrical cabinet is extinguished. The system is simple in fire extinguishing method, and the automatic fire extinguishing function of the electrical cabinet is achieved; fire extinguishing can be completed under the condition of not destroying the performance of the electrical elements and the cables in the electrical cabinet; sufficient evacuation time and clear escape routes can be provided for travelers, and secondary disasters happening after the fire disaster can be avoided; and when the fire disaster happens, sufficient preparationtime can be provided for train maintenance personnel to carry out self-rescue after the fire disaster.

Description

technical field [0001] The invention belongs to the field of high-pressure fine water mist fire extinguishing, and relates to an automatic fire extinguishing system and a fire extinguishing method for an electric cabinet of a rail vehicle. Background technique [0002] At present, electrical cabinets equipped with various electrical components (contactors, relays, air switches, etc.) and cables are widely used on rail vehicles. The safety of electrical cabinets directly determines the safe use of rail vehicles. At present, smoke and fire alarm equipment is installed in the electrical cabinet. When the electrical components or cables in the electrical cabinet are on fire due to aging, overload, etc., the smoke and fire alarm equipment will issue a smoke and fire alarm. The electrical cabinet is used to extinguish the fire, which will inevitably cause irreversible damage to all electrical equipment and cables in the electrical cabinet, especially the insulation properties of e...

[0002] At present, electrical cabinets equipped with various electrical components (contactors, relays, air switches, etc.) and cables are widely used on rail vehicles. The safety of electrical cabinets directly determines the safe use of rail vehicles. At present, smoke and fire alarm equipment is installed in the electrical cabinet. When the electrical components or cables in the electrical cabinet are on fire due to aging, overload, etc., the smoke and fire alarm equipment will issue a smoke and fire alarm. The electrical cabinet is used to extinguish the fire, which will inevitably cause irreversible damage to all electrical equipment and cables in the electrical cabinet, especially the insulation properties of electrical components and cables. It will cause serious panic and cause the expansion of disasters
