Abstract
The invention relates to a high-oil-level differential type leak detection device for an oil tank. The structure of the device is as follows: an oil storage tank is suspended and is connected with one end of an oil injection pipe and one end of an oil discharging pipe respectively; the other end of the oil injection pipe is connected with an oil pump; and the other end of the oil discharging pipe is connected with an oil outlet valve. According to the high-oil-level differential type leak detection device for the oil tank, by means of a high and low oil pressure differential principle, whether the oil tank of a transformer tank leaks oil or not can be detected accurately; a large number of experiments show that when the vertical height of the oil storage tank from the ground is 6 meters, the leak testing qualified rate can reach 100%, unexpected effect is acquired, long-time stable operation of the transformer oil tank is guaranteed, and the repairing and maintenance costs and the potential safety hazards are reduced.
Description
Technical field
The present invention relates to a kind of fuel tank leak-checking apparatus, relate in particular to a kind of high oil level drop height type fuel tank leak-checking apparatus for oil tank of transformer, belong to electric power application.
Background technology
Fuel tank seepage is one of FAQs of transformer, therefore how to avoid occurring such problem, and before transformer dispatches from the factory, it being solved is thoroughly a very important technical problem.The method of available technology adopting is that the whole trial assembly of transformer that will dispatch from the factory is complete, oiling is quiet puts 24 hours, check and have or not leak source, because internal oil pressure is little, before often existing transformer to dispatch from the factory, do not find seepage, but after actual motion, just have seepage situation to occur, not only repairing deals with very difficult, and there is very large potential safety hazard, cause puzzlement to normal power supply production run.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, for fundamentally solving Problem of Oil Leakage for Transformer Tank, utilize high-low-position oil principle of differential pressure, develop a kind of simple efficient high oil level drop height type fuel tank leak-checking apparatus, solved in prior art not problem accurately of oil tank of transformer leak detection.
Technical scheme of the present invention is as follows:
Fuel reserve tank hangs and arranges, and fuel reserve tank is connected with one end of oil fuel tube and one end of drain line respectively, and the other end of oil fuel tube connects oil pump, and the other end of drain line connects delivery valve.
Described fuel reserve tank is 6 meters apart from ground vertical height.
Described fuel reserve tank is provided with oil ga(u)ge.
Described oil fuel tube is connected with fuel reserve tank by screw thread with drain line.
The length that described oil fuel tube and drain line stretch into fuel reserve tank inside is less than the height of fuel reserve tank.
Described delivery valve is by flexible pipe connection transformer fuel tank.
Described delivery valve at least arranges one.
Advantageous effect of the present invention is as follows:
1, fuel reserve tank hangs and arranges, by high-low-position oil principle of differential pressure, can detect accurately whether leakage of oil of oil tank of transformer, and through a large amount of verification experimental verifications, fuel reserve tank, apart from 6 meters of ground vertical heights, can reach leak test qualification rate 100%, has obtained unexpected effect, guarantee oil tank of transformer operation steady in a long-term, reduced repairing maintenance cost and potential safety hazard.
2, oil fuel tube is connected with fuel reserve tank by screw thread with drain line, facilitates the replacing of oil pipe, uses flexibly.
3, the length that oil fuel tube and drain line stretch into fuel reserve tank inside is less than the height of fuel reserve tank, guaranteed oiling and drain the oil smooth and easy, and avoided fuel reserve tank inwall impurity to enter oil pipe.
4, delivery valve can arrange a plurality ofly, improves detection efficiency, saves cost.
Accompanying drawing explanation
Fig. 1 structural representation of the present invention.
In figure, 1, fuel reserve tank, 2, oil ga(u)ge, 3, drain line, 4, oil fuel tube, 5, delivery valve, 6, oil pump, h, fuel reserve tank bottom ground height.
Embodiment
The present invention, with reference to accompanying drawing, in conjunction with specific embodiments, is described in detail as follows.
Embodiment
Fuel reserve tank 1 hangs and arranges apart from 6 meters of ground vertical heights, fuel reserve tank 1 is connected with one end of drain line 3 with one end of oil fuel tube 4 respectively by screw thread, the other end of oil fuel tube 4 connects oil pump 6, and the length that oil fuel tube 4 and drain line 3 stretch into fuel reserve tank 1 inside is less than the height of fuel reserve tank.The other end of drain line 3 connects 3 delivery valves 5, and delivery valve 5 is connected with oil tank of transformer flange by flexible pipe.Described fuel reserve tank is provided with oil ga(u)ge 2.
During work, delivery valve branch road flexible pipe is connected to oil tank of transformer upper flange, opens oil switch, be filled with transformer oil, monitor after 24 hours, close oil switch, transformer is discharged after a small amount of oil, pulls down the branch road flexible pipe of connection, to detect oil tank of transformer leakage of oil situation.The present invention has thoroughly solved the problem of transformer oil box leakage, has guaranteed oil tank of transformer leak test reliability, and leak test oil pressure is stable, and constructing operation is simple and convenient.
