Abstract
The present invention relates to a kind of high oil level drop height type fuel tank leak-checking apparatus, and its structure is, 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.The present invention is by high-low-position oil principle of differential pressure, oil tank of transformer whether leakage of oil can be detected accurately, and through a large amount of verification experimental verifications, fuel reserve tank is apart from ground vertical height 6 meters, leak test qualification rate 100% can be reached, achieve unexpected effect, ensure that oil tank of transformer long-term stability is run, decrease repairing maintenance cost and potential safety hazard.
Description
Technical field
The present invention relates to a kind of fuel tank leak-checking apparatus, particularly relate 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 it being solved thoroughly before transformer dispatches from the factory is a very important technical problem.The method adopted in prior art is that the transformer whole trial assembly that will dispatch from the factory is complete, oiling is quiet puts 24 hours, check with or without leak source, because internal oil pressure is little, often exist before transformer dispatches from the factory and do not find seepage, but just have leakage scenarios to occur after actual motion, 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, a kind of simple efficient high oil level drop height type fuel tank leak-checking apparatus of development, to solve in prior art oil tank of transformer leak detection not problem accurately.
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, oil tank of transformer whether leakage of oil can be detected accurately, and through a large amount of verification experimental verifications, fuel reserve tank, apart from ground vertical height 6 meters, can reach leak test qualification rate 100%, achieve unexpected effect, ensure that oil tank of transformer long-term stability is run, decrease 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, ensure that oiling and drain the oil smooth and easy, and avoid fuel reserve tank inwall impurity and enter oil pipe.
4, delivery valve can arrange multiple, improves detection efficiency, saves cost.

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, ground height bottom h, fuel reserve tank.
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 apart from ground vertical height 6 meters and arranges, fuel reserve tank 1 is connected with one end of oil fuel tube 4 and one end of drain line 3 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 by flexible pipe and oil tank of transformer Flange joint.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, after a small amount of oil discharged by transformer, pull down the branch road flexible pipe of connection, to detect oil tank of transformer leakage of oil situation.The present invention thoroughly solves the problem of transformer oil box leakage, ensure that oil tank of transformer leak test reliability, and leak test oil pressure is stablized, and constructing operation is simple and convenient.
