Power transformer fire extinguishing system and control method

Abstract

The invention relates to the technical field of fire-fighting equipment, in particular to a power transformer fire extinguishing system and a control method. The power transformer fire extinguishing system comprises an equipment protecting room, a fire extinguishing pipe network, multiple fire detectors, point spraying branch control pipe valves and weatherproof porous bundling nozzles; a gas cartridge set, a starting bottle set, a 3D boiling powder storage tank and a fire extinguishing controller are arranged in the equipment protecting room, and the fire extinguishing controller is provided with a multi-feature signal detector, an air speed detector and a reburning detection and alarm controller. The control method comprises the following steps of initialization, fire detection, alarm and fire extinguishment; the fire extinguishment comprises the steps of point fire extinguishing scheme generating, multi-point fire extinguishing scheme generating and full fire extinguishing scheme generating. According to the power transformer fire extinguishing system and the control method, the main pipe network is buried under a terrace, the safety is high, and the stable reliability of the fire extinguishing system is guaranteed; a point fire extinguishing scheme, a multi-point fire extinguishing scheme and a full fire extinguishing scheme are designed according to different fire types, and the fire extinguishing efficiency and the fire extinguishing effect are greatly improved.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a power transformer fire extinguishing system and a control method. Background technique [0002] At present, the fire-fighting measures for large-scale oil-immersed power transformers in China mainly use fixed fire-extinguishing systems such as water spray, foam spray, oil discharge and nitrogen injection, and auxiliary fire-fighting facilities such as sand boxes, sand buckets, hand-held and cart-type fire extinguishers. Although the dry powder fire extinguishing system has the advantages of high fire extinguishing efficiency, water saving, energy saving, cold protection, safety, and environmental protection, because the indoor transformer dry powder fire extinguishing system cannot properly solve the problem of cooling the high-temperature transformer oil and extinguishing the reburning fire, the outdoor transformer dry powder fire extinguishing system cannot be ...
