Description
Technical field
The utility model relate to a kind of power station, substation capacity more than 10MVA large oil immersed formula transformer and the fire-fighting device of similar charging power equipment.
Background technology
Transformer might be crossed high fault because of short circuit, oil temperature and cause the phenomenon of catching fire in running, is support equipment safety, and automatic fire extinguisher is installed on transformer.Extinguishing device commonly used is an oil draining nitrogen filling fire extinguishing device, and it is made up of FHC, fire detector, Buchholz relay, shutoff valve and control circuit; Nitrogen cylinder group and controlled oil extraction pipeline are arranged in the FHC; The nitrogen cylinder group connects the oil tank of transformer bottom by annotating the nitrogen loop, annotates on the nitrogen loop nitrogen injecting valua is installed; Controlled oil extraction pipeline is equipped with service valve and draining valve, and its end connects oil storage pool, and the other end is connected the top of oil tank of transformer by the oil extraction pipeline, on the oil extraction pipeline service valve is installed.When breaking down, the transformer temperature raises, and fire detector reaches operating temperature, sends signal and gives control circuit; Produce a large amount of gas simultaneously, Buchholz relay sends signal and gives control circuit simultaneously, draining valve in the FHC is opened and is carried out oil extraction, meanwhile, nitrogen in the nitrogen cylinder is entered by the transformer bottom by annotating the nitrogen loop, makes that bottom low temperature oil mixes temperature in the reduction fuel tank in the fuel tank with the top high temperature oil, make the surface oil temperature drop below burning-point, flame extinguishes automatically in the fuel tank.Because draining valve adopts mechanical weight to open, its opening speed is slow, and misoperation easily takes place, and needs hand reset, complex operation after the action.Nitrogen injecting valua needs manually opened, starts slowly, in case of emergency influences the rapid enforcement of fire-fighting work, and easily leaks gas.
Summary of the invention
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provides a kind of unlatching rapidly reliable, and can effectively prevent nitrogen leak, prevent from the to put out a fire oil draining nitrogen filling fire extinguishing device for transformer of misoperation.
For finishing above-mentioned purpose, technical solution of the present utility model is: a kind of oil draining nitrogen filling fire extinguishing device for transformer, and it comprises FHC, a plurality of fire detector, Buchholz relay, shutoff valve and control device; Nitrogen cylinder group and controlled oil extraction pipeline are arranged in the FHC; The nitrogen cylinder group connects the oil tank of transformer bottom by annotating the nitrogen loop, annotates on the nitrogen loop nitrogen injecting valua is installed; Controlled oil extraction pipeline is equipped with service valve and draining valve, and controlled oil extraction pipeline one end connects oil storage pool, and the other end is connected the top of oil tank of transformer by the oil extraction pipeline, on the oil extraction pipeline service valve is installed; The control end of a plurality of fire detectors, Buchholz relay and shutoff valve is connected control device by lead respectively; It is characterized in that: draining valve and nitrogen injecting valua are magnetic valve, and its control end connects control device by lead.
The ZCZP universaling electromagnetic valve that the above-mentioned described draining valve of the utility model is a high-temperature explosion-proof, nitrogen injecting valua is the ZCZP universaling electromagnetic valve.
Because draining valve of the present utility model and nitrogen injecting valua adopt magnetic valve, it directly controls its keying by control device, opens reliably rapidly, and can effectively prevent the leakage of nitrogen, the generation of the misoperation that prevents to put out a fire.Its fire extinguishing rapidly, has reliably been saved working strength of workers.
