Description
Technical Field

Background
With the rapid development of national economy, the scale of the power grid is rapidly enlarged, and the operational reliability of the power transformation equipment faces more severe examination. The oil-immersed power transformer is the core of a transformer substation, and once a fire disaster occurs, the power grid of the whole area is paralyzed, the reliability and the safety of power supply are seriously damaged, and the social influence and the damage are extremely large. The existing fire extinguishing equipment suitable for the large oil immersed transformer mainly comprises a water spray fire extinguishing system, a synthetic foam spray fire extinguishing device, an oil discharge and nitrogen charging fire extinguishing device and a water mist fire extinguishing device.
(1) Water-spray fire suppression system: the fire extinguishing medium is water; the device mainly comprises a fire pool, a water supply pump set, a deluge valve, a pipe network, a water mist spray head and the like. The fire extinguishing apparatus extinguishes fire by a fire extinguishing mechanism of surface cooling, suffocation and emulsification by generating water spray. Due to the reasons of low fire extinguishing efficiency, large water consumption, long fire extinguishing time, large occupied area of facilities such as a fire-fighting water pump room, a fire-fighting water pool and the like, the method is not suitable for the environment of an outdoor transformer substation, has the problems of serious corrosion of pipelines and valves, high maintenance cost and the like, and is difficult to keep the fire extinguishing equipment in a perfect servo state.
(2) Synthetic foam spray extinguishing device: the fire extinguishing medium is foam premixed liquid and mainly comprises a foam premixed liquid storage tank, a nitrogen driving bottle, a nitrogen starting bottle, a pressure reducer, a control valve, a pipe network and a water mist spray head. When the device is used, the foam and the water need to be premixed firstly and then stored in the foam premix liquid storage tank, the quality guarantee period is short (the replacement is needed in 2 years), the maintenance cost is high, and the storage amount of the stored foam premix liquid can only be sprayed for 10 min; after the spraying, the foam premixed liquid and the nitrogen are required to be refilled, uninterrupted fire protection cannot be achieved, continuous subsequent cooling or fire extinguishing measures cannot be carried out, and the problem of re-combustion is easily caused.
(3) Oil discharge and nitrogen charge fire extinguishing apparatus: the fire extinguishing medium is nitrogen and mainly comprises a fire extinguishing cabinet, a nitrogen injection pipeline, an oil discharge pipeline, a detector, a pressure controller and a stop valve. The fire-extinguishing cabinet comprises a nitrogen cylinder, a pressure reducer, a nitrogen release valve, an exhaust valve, a one-way valve, a quick oil discharge valve and the like. The device's nitrogen device is annotated to oil extraction and transformer body are directly connected, and the easy corrosion of pipeline, seepage cause device malfunction and transformer trouble easily, therefore the operational risk is big, and can not put out the outside conflagration of transformer after catching a fire.
(4) Water mist fire extinguishing device: the fire extinguishing medium is water and mainly comprises a water tank, a water supply pump set, a partition control valve, a pipe network, a fine water mist spray head and the like. The diameter of the fine water mist is very small, so that the fine water mist is easily blown away by airflow, the wind resistance is poor, the fine water mist is not suitable for outdoor oil-immersed power transformers, and the fire extinguishing time is long.
