Description

A kind of novel transformer explosive fire accident fire extinguishing system

Technical field

It the utility model is related to fire-fighting equipment technical field, especially oil-immersed power transformer fire extinguishing system.

Background technology

In recent years, the power equipment gone into operation with the last round of power construction peak period in China subsequently enters upgrading Phase, because Accident of Transformer caused by ageing equipment and loss has increased trend.On July 10th, 2015, city of Yunnan Province 500kV becomes single-phase main transformer bushing and serious explosive fire accident occurs, and is analyzed by the scene of the accident, transformer fire extinguishing system pipe network The sleeve pipe damage blown up, can not be used, Transformer Bushing Overhaul flange blows up that 50m is remote, and transformer oil crosses fire wall splash Arrive with adjacent single-phase transformer, because the transformer high-voltage bushing position of the blast is special, adjacent transformers are arrived in splash Oil mass is less, otherwise most probably causes adjacent transformers working fire；On June 18th, 2016, southern Xi'an City 330KV transformer stations because Equipment fault causes 3 transformers to recur fire.Cause of fire is due to that cable duct catches fire and caused, and fire is initially spread to After a nearest main transformer, because active fire measure failure causes the condition of a fire to continue to spread to adjacent main transformer and distribution Device place, and trigger remaining two main transformer in succession slight on fire from explosion, accident causes Xi'an that of short duration, large area occurs Have a power failure.

Found after being analyzed by fire cases, water spray, the dry powder that current domestic large oil immersed power transformer uses Spraying, dry powder, oil draining nitrogen filling fire extinguishing device can only put out a fire to save life and property light transformer microburst fire, the transformer moderate that can not put out a fire to save life and property, serious Explosive fire accident.Existing fire extinguishing system is primarily present problem：1) Explosion of Transformer fire is usually formed sprawling outside transformer, held Continuous resume combustion fire and it is internal continue resume combustion fire, at present transformer fire extinguishing system be only provided with water spray, dry powder, dry powder or A kind of fire extinguishing system such as person's oil draining nitrogen filling, the Explosion of Transformer fire that can not put out a fire to save life and property simultaneously, the outer fire of interior fire；2) transformer oil splash stream Drop down scope and exceed transformer fire extinguishing system protection domain, can not put out a fire to save life and property more than the spreading of fire extinguishing system scope, continue resume combustion fire； 3) existing transformer fire extinguishing system warning device can not be accurately positioned to fire position, and whole shower nozzles blindly once spray simultaneously Fire extinguishing is penetrated, no fire position spray fire extinguishing agent is excessive, and fire extinguishing keypoint part fire extinguishing injection protection is inadequate；4) warning device is once reported Alert, extinguishing chemical once sprays, and can not put out a fire to save life and property resume combustion fire, fire extinguishing failure；5) pipe network explosion-protection equipment is not provided with, pipe network quilt of putting out a fire The damage failure of Explosion of Transformer part；6) external environmental factors such as wind speed, rainfall are not considered, have a strong impact on extinguishing effect；7) it is existing It may cause electrical equipment pollution flashover problem with the presence of powder extinguishing system dry powder dust；Nitrogen filling fire extinguishing device exist numerous malfunctions, Tripping problem；There is drought and water shortage in existing other transformer fire extinguishing systems, high and cold refrigerated environment condition can not be used or used Difficult problem.

Therefore, in the case of transformer fire accident caused by power equipment aging and loss is substantially increased, one is developed It is extremely urgent important thing to cover effective Explosion of Transformer fire fire extinguishing system.
