Abstract
A transformer fire extinguisher which can prevent false operations is provided, which belongs to the technical field of Fire Fighting Equipment and is used for solving the false operation problems of a transformer fire extinguisher. The technical proposal is: the utility model comprised a box body, a nitrogen cylinder, a nitrogen injecting tube, an oil-discharge butterfly valve, a ball valve and a linking, wherein the ball valve is arranged in the nitrogen injecting tube, and one end of the linking is connected with the swing link of the oil-discharge butterfly valve, while the other end is connected with the handle of the ball valve. By the catenation of the ball valves, the utility model can prevent effectively nitrogen from coming into the oil tank of the transformer and causing false operations of the transformer and abnormal power failure; while in case of fire, the utility model can allow the ball valve to be linked with the oil-discharge butterfly valve quickly, and perform normal fire-extinguishing operation by injecting nitrogen and ensure the operating security of the transformer.
Description
Technical field
The utility model relates to a kind of can preventing and belongs to the fire-fighting equipment technical field because of nitrogen leaks the transformer extinguishing device that causes misoperation.
Background technology
Therefore transformer might must equip automatic fire extinguisher because the high fault phenomenon of catching fire is crossed in short circuit, oil temperature in running.Extinguishing device commonly used comprises transformer oil extraction-nitrogen filling fire extinguishing device, and this device becomes low-pressure nitrogen by pressure-reducing valve with high pressure nitrogen, annotates the people then and puts out a fire in transformer.Find in actual use; firing-fighting medium nitrogen in transformer oil extraction-nitrogen filling fire extinguishing device also can leak in the oil tank of transformer, can cause tripping operation after the Buchholz relay in the protected device monitors, and makes transformer out of service; cause power outage, influenced the normal operation of productive life.
Summary of the invention
The utility model is used to provide a kind of and can effectively stops nitrogen to enter oil tank of transformer, prevents the transformer extinguishing device of transformer oil extraction-nitrogen filling fire extinguishing device misoperation.
The technical scheme that addresses the above problem is:
A kind of transformer extinguishing device that prevents misoperation, it comprises casing, nitrogen cylinder, notes nitrogen pipeline, oil extraction butterfly valve, its improvements are, it also is provided with ball valve, connecting rod, wherein, ball valve is installed in to be annotated in the nitrogen pipeline, and connecting rod one end is connected with the fork of oil extraction butterfly valve, and the other end is connected with the handle of ball valve.
The above-mentioned transformer extinguishing device that prevents misoperation, it also is provided with a safety valve, and safety valve is connected in the pipeline of the notes nitrogen pipeline between ball valve and the nitrogen cylinder.
The utility model can under normal circumstances enter oil tank of transformer by the chain nitrogen that prevents effectively of ball valve, thereby causes the transformer misoperation, causes improper power outage; And under the situation of catching fire, it can allow the interlock of ball valve and oil extraction butterfly valve, enforcement annotate nitrogen fire extinguishing action normally again rapidly, guarantees the security of operation of transformer.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Each mark is as follows among the figure: casing 1, nitrogen cylinder 2, notes nitrogen pipeline 3, oil extraction butterfly valve 4, ball valve 5, connecting rod 6, safety valve 7, oil extraction pipeline observation tube 8.
The specific embodiment
Show among the figure that the utility model is by casing 1, nitrogen cylinder 2, notes nitrogen pipeline 3, oil extraction butterfly valve 4, ball valve 5 and connecting rod 6 are formed.Compare with general transformer oil extraction-nitrogen filling fire extinguishing device, ball valve 5 and connecting rod 6 have been increased, ball valve 5 is installed in to be annotated in the nitrogen pipeline 3, connecting rod 6 one ends are connected with the fork of oil extraction butterfly valve 4, the other end is connected with the handle of ball valve 5, and ball valve 5 is realized chain being synchronized with the movement with oil extraction butterfly valve 4 by connecting rod 6.
Under the situation of transformer operate as normal; ball valve 5 is to be in closed condition; nitrogen in the nitrogen cylinder 3 can not advance in the fuel tank of people's transformer by annotating nitrogen pipeline 3, has avoided influencing the normal operation of transformer because the nitrogen that leaks causes the protection equipment for transformer misoperation.
When the transformer breaking out of fire, when manually fire extinguishing startup or self-extinguishing start, the downward dextrorotation of the fork of oil extraction butterfly valve 4 turn 90 degrees, open oil extraction butterfly valve 4, open by connecting rod 6 simultaneously and annotate ball valve 5 in the nitrogen pipeline 3, make that the later pipeline of notes nitrogen pipeline 3 pressure-reducing valves is unimpeded, possess the condition of filling nitrogen, nitrogen cylinder 2 was opened after electric detonator was ignited after 20 seconds, and nitrogen enters oil tank of transformer by ball valve 5 and puts out a fire.
The utility model has also been installed a safety valve 7 on the tube wall of annotating nitrogen pipeline 3, if the nitrogen of nitrogen cylinder 2 has micro-leakage, nitrogen will discharge (under authorized pressure) by safety valve 7, switch to outside the pipeline, guarantee the safe operation of transformer.
Whether oil circuit has the seepage phenomenon under the transformer running status in order to observe, and oil extraction pipeline observation tube 8 also has been installed on the oil extraction pipeline, makes operating personnel can understand the ruuning situation of oil extraction pipeline at any time.
