Abstract
The utility model provides an exhaust device of an oil filling pipeline, relating to a gas exhaust device used in vacuum oil filling of a large oil immersed type transformer. The exhaust device consists of an oil pipe (1) and an exhaust pipe (2) which are communicated with each other, a valve (3) is arranged at the tail end of the exhaust pipe (2), connecting flanges are arranged at two ends of the oil pipe (1) and are respectively connected with an oil filling valve and an oil outlet pipe of an oil filter, the oil filling valve is closed, transformer oil enables gas in the pipeline to be exhausted through the oil pipe (1) and the exhaust pipe (2), and then the valve (3) is closed, the oil filling valve is opened, and then oil is filled in a transformer, so as to effectively solve the problem that pipeline gas enters the transformer and improve the oil filling efficiency.
Description
Technical field
The utility model relates to a kind of exhaust apparatus of oiling pipeline, the air scavenge device that uses when being specially a kind of large oil immersed formula transformer vacuum oil.
Background technology
At present, large oil immersed formula transformer is after assembling is finished, need vacuum oil, transformer oil generally enters transformer through behind the oil filter, but has a drawback on this oiling pipeline, and oil filter to the gas in the pipeline between the oiling transformer valve can't be discharged, to directly enter transformer inside, increase the weight of burden and the workload of transformer vacuum pumping, improved production cost to a certain extent, and influenced production efficiency with power-equipment.
Summary of the invention
The purpose of this utility model is exactly that the convenient tubes rows device of air of getting rid of gas in a kind of oil-filled transformer oiling process will be provided.
A kind of oiling pipeline exhaust apparatus, it comprises oil pipe, blast pipe composition, and blast pipe is communicated with oil pipe, and the blast pipe end is provided with valve, and the oil pipe two ends are provided with adpting flange, connect with fuel feeding valve, oil filter flowline respectively.
Described blast pipe and oil pipe junction are arranged on nearly fuel feeding valve end, so that gas is extruded completely in the pipeline, do not stay remnants.
Oiling pipeline exhaust apparatus also comprises oil storage box, and oil storage box is communicated with the valve of blast pipe.
Operation principle of the present utility model is: vacuumize before filling procedure begins carrying out transformer, close fuel feeding valve, open exhaust valve, transformer oil enters oil pipe through the oil filter pipeline, when arriving fuel feeding valve, the transformer oil break-in enters blast pipe, and the trapped gas in the pipeline is extruded by blast pipe, when exhaust valve is fuel-displaced, show that pipeline gas discharges, collect the transformer oil of discharging, close exhaust valve by oil storage box, open fuel feeding valve, transformer is carried out oiling get final product.
The beneficial effects of the utility model are: by the control of valve, the trapped gas in the pipeline is got rid of by blast pipe, effectively solved the drawback that pipeline gas enters transformer, improved the efficient that transformer vacuumizes oiling.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram.
Embodiment
Oiling pipeline exhaust apparatus as shown in Figure 1, it is arranged between oiling transformer pipeline fuel feeding valve and the oil filter, it comprises oil pipe 1, blast pipe 2 compositions, blast pipe 2 is communicated with oil pipe 1, blast pipe 2 ends are provided with valve 3, oil pipe 1 two ends are provided with adpting flange, and oil pipe 1 connects with fuel feeding valve and oil filter flowline respectively by adpting flange.
Described blast pipe 2 is arranged on nearly fuel feeding valve end with oil pipe 1 junction, so that gas is extruded completely in the pipeline, does not stay remnants.
Oiling pipeline exhaust apparatus also comprises oil storage box, and oil storage box is communicated with the valve 3 of blast pipe.
Operation principle of the present utility model is: vacuumize before filling procedure begins carrying out transformer, close fuel feeding valve, open exhaust valve 3, transformer oil enters oil pipe 1 through the oil filter pipeline, when arriving fuel feeding valve, the transformer oil break-in enters blast pipe 2, trapped gas in the pipeline is extruded by blast pipe 2, when exhaust valve 3 is fuel-displaced, show that pipeline gas discharges, collect the transformer oil of discharging, close exhaust valve 3 by oil storage box, open fuel feeding valve, transformer is carried out oiling get final product.
