Abstract

The compressed air foam water mist fire extinguishing system for the urban fusion type transformer substation cable trench comprises a fire monitoring device, a fire alarm controller, a main controller, a compressed air foam water mist device, a partition control valve and a fire extinguishing nozzle, the fire monitoring device is used for collecting fire information in a cable trench of an urban integrated transformer substation and sending the fire information to the fire alarm controller, and the fire alarm controller judges whether a fire occurs or not according to the fire information collected by the fire monitoring device and sends fire alarm information to the main controller. After receiving fire alarm information, the main controller controls the compressed air foam water mist device to generate foam water mist fire extinguishing liquid, and meanwhile, controls the partition control valve of a fire area to be opened; the foam water mist fire extinguishing liquid is sprayed into a cable trench of an urban fusion type transformer substation through a fire extinguishing nozzle in a fire area for fire extinguishing. The fire extinguishing liquid is accurately mixed and provided in real time, a fire area is rapidly covered, and rapid fire extinguishing is achieved.

Description

technical field [0001] The invention relates to a compressed air foam fine water mist fire extinguishing system for a cable trench of an urban integration type substation, and belongs to the technical field of fire protection for the cable trench of an urban integration type substation. Background technique [0002] In view of the difficulty in planning and construction of urban substations, three types of urban integration substations, "environmentally integrated substations", "adjacent integrated substations" and "embedded integrated substations", have been proposed to promote the integrated development of power grids and cities. Promote the coordinated and integrated development of substations and urban buildings, transmission lines and urban utility tunnels. [0003] The cable runs safely during normal operation, but when it is under overload, short circuit, local overheating and other fault conditions and under the action of external heat, it will cause the insulation r...
