Description

For recharging oil device and the oil supplement method thereof of Full-enclosed oil-immersed transformer
Technical field
The present invention relates to the recharging oil device for Full-enclosed oil-immersed transformer and oil supplement method thereof.
Background technology
Current Full-enclosed oil-immersed transformer adopts vacuum oil technique substantially, for preventing overflowing due to oiling overfill in vacuum chamber, the fuel head of general oiling can not exceed case lid height, but level height h2 in Full-enclosed oil-immersed transformer oil fuel tube 2 requires must higher than the height h1(of the high voltage porcelain bushing 7 of Full-enclosed oil-immersed transformer 1 as shown in Figure 1), otherwise operationally may there is flashover due to bushing 7 inner oil shortage in transformer; In bushing 7, there is flashover, make again to be full of transformer oil in oil fuel tube 2 simultaneously, therefore under atmospheric pressure must carry out repairing operation to oil fuel tube.
The method of current repairing: as shown in Figure 1, a conical hopper is plugged the suitable for reading of oil fuel tube 2, with oil can oiling at a slow speed in funnel (accelerate and can affect air spilling or excessive spilling), because the internal diameter of oil fuel tube only has 28 ~ 30mm, the oil level height in oil fuel tube cannot be seen clearly by naked eyes at all, even the oil fuel tube 2 of band form is also careful cautiously, often can cause and not be added to target oil level or oil level too much (exceeding target oil level) and overflow (height that target oil level is the oil level in our actual desired oil fuel tube), do case lid 8 is all oil.Secondly, the drawback also existed is; Under atmospheric pressure refuel and have bubble generation unavoidably, could discharge after this bubble needs the long period, the discharge of bubble causes again the decline of the oil level in oil fuel tube, need the operation of repairing again, the weak point of above-mentioned existence, causes the inefficiency that repairing operates, wastes time and energy.
Summary of the invention
The technical problem to be solved in the present invention is, when providing a kind of oil fuel tube to Full-enclosed oil-immersed transformer to carry out repairing, accurately the oil level in oil fuel tube can be adjusted to target oil level, spilling can not be caused because oil level is too high, the recharging oil device for Full-enclosed oil-immersed transformer of transformer box cover of making dirty simultaneously.
For solving the problems of the technologies described above, technical scheme provided by the invention is: a kind of recharging oil device for Full-enclosed oil-immersed transformer, and it comprises the taper priming funnel assembly sealed in the oil fuel tube inserting Full-enclosed oil-immersed transformer and with oil fuel tube; Described taper priming funnel assembly is provided with oil filler; Described taper priming funnel assembly is provided with for the oil level in oil fuel tube being adjusted to target oil level and unnecessary oil plant being discharged to from oil fuel tube the overflow mechanism in the oil reclamation device that Full-enclosed oil-immersed transformer is provided with.
Preferred as one, described overflow mechanism comprises inverted U-shaped pipe; Described U-shaped pipe comprises one end and is located at the other end in taper priming funnel assembly and passes arc overflow pipe outside taper priming funnel assembly, pass discharger that one end outside taper priming funnel assembly is communicated with arc overflow pipe and being located at of being communicated with the arc overflow pipe other end overflows into pipe in oil fuel tube; Wherein, the oil plant overflowing into pipe described in overflows into the top that port is positioned at the oil plant spilling port of discharger; The oil plant of described discharger overflows the top that port is positioned at oil reclamation device.
Preferred as one, described arc overflow pipe is located at the bottom of nearly taper priming funnel assembly.
Preferred as one, described arc overflow pipe is the body that metal material is made.
Preferred as one, the outer wall of described arc overflow pipe is fixed with the inwall of the through hole that confession arc overflow pipe on taper priming funnel assembly passes and seals.
Preferred as one, it also comprises blast pipe; The air inlet port of described blast pipe is arranged in oil fuel tube, and the air inlet port of blast pipe overflows into port higher than the oil plant overflowing into pipe; The air discharge port of described blast pipe passes taper priming funnel assembly and is in communication with the outside.
