Abstract
A vacuum oil filling system for a transformer comprises an overhead oil tank, a vacuum tank and a transformer needing vacuum oil filling. Finished oil is stored in the oil tank, a vacuumizing pipeline is arranged on the oil tank and connected with a vacuumizing device, a pipeline between the oil tank and the transformer is provided with an oil pump which is a volumetric oil delivery pump, and a pipeline between the oil pump and the transformer is provided with a flow meter. By pre-vacuumizing the oil tank, vacuum oil filling is realized, the oil flow velocity is controlled, foam and oil spill caused by bubbles formed by gradual volume expansion in the oil filling process are avoided.
Description
Technical field
The utility model relates to the transformer technology field, relates in particular to transformer production technology, a kind of transformer vacuum oil system.
Background technology
Transformer vacuum oil is in order to expel the bubble in the transformer oil effectively; Improve the insulation level of transformer; To getting together under the situation that potential difference is bigger between the formula coil turn, prevent to exist bubble to cause under the bigger situation of turn-to-turn potential difference especially, prevent to exist bubble to cause the breakdown between adjacent turns accident.Common transformer vacuum oil technology is as shown in Figure 1, comprises built on stilts oil tank 1, vacuum tank 2 and needs the transformer 3 of vacuum oil.During vacuum oil, produce oil whip in the oil tank of transformer, lather collapse causes fluid to splash, and causes the fuel tank top that oil stain is arranged, and is prone to cause the liquid level gauge misoperation that is placed in the transformer.Through analyzing reason be: in product oil gets into jar, during fuel tank, under high vacuum state, be dissolved in the minimum gas in the oil; Because pressure reduces; The volume formation bubble that expands gradually in the oiling process, and float to liquid level and break by the fuel tank bottom, thereby cause foam and fluid to spill; Oil flow velocity degree is bigger during oiling.Above-mentioned vacuum oil mode is that transformer product tank frame is put in a high position, and oil level is in a high position, carries out vacuum oil through vacuumizing with the level height difference, and controls oily flow velocity degree through valve, and oily flow velocity degree is wayward.
The utility model content
The utility model is the shortcoming to above-mentioned existence, and a kind of transformer vacuum oil system is provided, and can control oily flow velocity degree can be not too fast, avoided the phenomenon that causes foam and fluid to spill in the oiling process.
The technical scheme that technical problem adopted that the utility model solves is:
A kind of transformer vacuum oil system; Comprise oil tank, vacuum tank of making somebody a mere figurehead and the transformer that needs vacuum oil in a high position; Store product oil in the oil tank; It is characterized in that oil tank is provided with vacuum lead, vacuum lead is connected with vaccum-pumping equipment, and the pipeline between oil tank and the transformer is provided with oil pump.Carry out vacuum oil after built on stilts product oil taken out certain vacuum degree, just avoided in the oiling process volume formation bubble that expands gradually, the phenomenon that causes foam and fluid to spill.
During practical implementation, oil pump is the positive displacement oil transfer pump.Vacuum oil mode after the improvement is carried out vacuum oil to making somebody a mere figurehead after finished product is taken out predetermined vacuum level, and adopts positive displacement oil transfer pump control oil transportation speed, can accurately control oily flow velocity degree.
During practical implementation, the pipeline between oil pump and the transformer is provided with flowmeter.Adopted high precision flow, can be by volume or mass metrology, thus can be than the oil mass of using of accurate measurement transformer body.
The beneficial effect of the utility model is: the utility model carries out vacuum oil through after oil tank is carried out forvacuum, and controls oily flow velocity degree, has avoided in the oiling process volume formation bubble that expands gradually, the phenomenon that causes foam and fluid to spill.
Description of drawings
Below in conjunction with accompanying drawing and embodiment utility model is further specified.
Fig. 1 is the technological process principle schematic of prior art.
Fig. 2 is the technological process principle schematic of the utility model embodiment.
Among the figure: 1, oil tank 2, vacuum tank 3, transformer 4, vacuum lead 5, positive displacement oil transfer pump 6, high precision flow 7, valve.
Embodiment
In Fig. 2, a kind of transformer vacuum oil system comprises oil tank 1, vacuum tank 2 of making somebody a mere figurehead in a high position and the transformer 3 that needs vacuum oil; Store product oil in the oil tank 1,1 height that is put in 5m-7m of oil tank, oil level is in a high position; Oil tank 1 is provided with vacuum lead 4; Vacuum lead 4 is connected with vaccum-pumping equipment, and the pipeline between oil tank 1 and the transformer 3 is provided with positive displacement oil transfer pump 5 and high precision flow 6, and the pipeline between oil tank 1 and the positive displacement oil transfer pump 5 is provided with valve 7.
The vacuum oil mode of the utility model to the product oil that stores in the built on stilts product tank 1, is carried out vacuum oil after taking out predetermined vacuum level, and is adopted positive displacement oil transfer pump 5 control oil transportation speed, can accurately control oily flow velocity degree.Adopted high precision flow 6 in addition, thus can be than the oil mass of using of accurate measurement transformer body.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all should think the protection range that belongs to the utility model.
