Abstract
A sealing technique for oil reservoir of transformer features that inertial gas (such as argon) under one atmosphere pressure is used to isolate oil from ambient atmosphere and gas bag. It has high sealing effect to prevent transformer oil from deteriorating or ageing.
Description
The following several seals style of the many now employings of transformer oil conservator (conservator):
1. through the directly logical atmosphere of respirator of band drier, some miniature transformers are not with the directly logical atmosphere of respirator.
2. adopt special colloid air bag to seal.
3. adopt the diaphragm seal technology.
Now in first kind of pattern of the most employings of the medium and small transformer oil conservator of labour.Subject matter is that the transformer oil in the oil conservator is directly to communicate with atmosphere basically, and transformer oil is deterioration easily, and may cause accident to take place.
Part transformer oil conservator adopts the seal style of band air bag, after the application several years transformer oil flash-point downward trend is arranged, and operating position is also not ideal enough, overhauls also cumbersome.
To some large and medium-sized transformer adopting diaphragm seal technology, seal point is many in recent years, wants complicated in the manufacturing, and oil level shows so not directly perceived, and its weak point is also arranged.
Here the oil conservator novel sealing technical scheme of Ti Chuing is different from above-mentioned three types.Can be referred to as inert gas capsule (barrier film) isolating seal device.Can guarantee fully that the oil of transformer oil conservator is isolated with atmosphere.And manufacturing technology is simple, uses to adjust all to make things convenient for.Also implement easily in the transformer Oil Tank transformation of labour for the scene especially, very favourable to preventing the transformer oil quality deterioration.
Attached technical scheme schematic diagram in the back [figure (). suitable capsule sealing; Figure (two). the suitable diaphragm seal that blocks], its principle is roughly similar with the capsule sealing, all is to utilize the breathing of capsule (barrier film) volume to be used for adapting to the variation of transformer oil conservator oil level.But this installs unique following technical characterstic:
1. the complete different transformer oil of capsule directly contact, and have prevented that capsule (barrier film) long period of soaking from producing the possibility of certain chemistry, physical change in transformer oil.
2. the utilization of this device charges into and approximates an atmospheric inert gas, makes transformer oil and atmosphere and capsule (barrier film) isolated fully, and is favourable to preventing oil quality deterioration.
3. the indication of the oil level of oil conservator can be accomplished demonstration directly perceived.
4. breather tank and capsule underlying, and assemble necessary table meter (monitoring the inert gas air gauge as adorning) and can in time find the situation whether capsule leaks gas by inspection hole.
5. whole oil conservator system sealing point significantly reduces, and the possibility of gas leak of the oil leakage also significantly reduces.Find capsule (barrier film) gas leakage even be in operation, do not have a power failure and also can in time change processing.Maintenance management brings great convenience to inspection travel.
6. long period of soaking is not in oil for air bag (barrier film), and the maintenance environmental condition is improved, and repairs easily, and also prolong relatively its useful life.It is so strict that the oil resistance of capsule (barrier film) is required also not resemble the capsule that is immersed in the oil.
7. unique a fly in the ointment is to have increased the breather tank that its volume is slightly larger than the capsule volume in addition, needs to increase the part investment.But the ratio that this part skill money accounts in the transformer investment is very little, comes than just more seeming insignificant with the security reliability of transformer.
8. as adopting figure (two) technical scheme, easy to process because of its diaphragm seal circle is garden shape, can fully guarantee good seal.
Claims (1)
- Apparatus of the present invention are transformer oil conservator (conservator) novel sealing technical scheme.It is characterized in that: utilize cross over pipe to link to each other with the special breather tank of a band seal capsule, and at the upper space of oil conservator and be attached thereto the capsule space that connects communicating pipe and inject the inert gas that approximates an atmospheric pressure, capsule (barrier film) is in shape shown in the accompanying drawing.Make in the oil conservator transformer oil fully and atmosphere and capsule (barrier film) isolated.Its unique technical characterstic is in the above-mentioned specification shown in the 1-8 bar.Above-mentioned characteristic feature is the claimed technical characterictic of the technical program.
