Abstract

The utility model relates to a fully sealed bursa film type oil storing tank which is composed of an upper barrel body, a lower barrel body, sealing pads, a bursa film, a cover plate, a gas filtering box, an oil pouring and expelling joint, a gas collecting box, a filth collecting device, a vacuum butterfly valve, etc. The inner part of the lower barrel body is provided and separated with the sealing pad and the bursa film, the left lower part of the lower barrel body is provided with the filth collecting device, the right lower part of the lower barrel body is provided with the gas collecting box whose lower part is provided with the oil pouring and expelling joint, the left side of the gas collecting box is provided with the vacuum butterfly valve, the sealing pad is arranged between the upper barrel body and the lower barrel body and fixes the upper barrel body and the lower barrel body into integration. The utility model has the advantages of scientific idea, novel design, reliable performance, low cost, no leakage and no pollution.

Description

Hermetically sealed film oil conservator

The utility model relates to a kind of Fuel Tanking Unit of power transformer in the electromechanical industries.

At present, the oil conservator on the power transformer does not have desirable solution seepage way always in the domestic and international electromechanical industries.The use of transformer had spread all over the town and country the earth during electric power was carried now, use extremely extensive, oil conservator kind on the transformer is a lot, but it is most of because its project organization is unreasonable, there are some problems again in processes, the second-rate improper use of potted component, therefore oil leakage phenomenon is extremely serious, a large amount of wastes of oil plant had both been caused, use cost increases, and has polluted environment again, but also causes fire and other accidents easily, therefore, develop a kind of full envelope film oil conservator is new scientific research task anxious to be solved in the domestic and international electromechanical industries always.

The purpose of this utility model be exactly conceive the science novelty in order to provide a kind of, project organization is reasonable, processes is convenient, properties of product are reliable, cost is lower, do not produce oil leak, non-environmental-pollution and be not prone to the hermetically sealed film oil conservator of other danger.

The purpose of this utility model is achieved in that whole device is by upper barrel body, lower barrel body, sealing gasket, membrane vesicle, venting is chewed, support, connecting rod, cover plate, filter gas box, oil level gauge, glass plate, annotate oil outlet fitting, collector box, relay connector, dirt trap, drain plug, dividing plate, vacuum butterfly valve is formed, dividing plate is installed in lower barrel body, on dividing plate, add fixedly membrane vesicle of sealing gasket, at lower barrel body left surface dress drain plug, lower left quarter is installed dirt trap, at the lower barrel body right lower quadrant collector box is installed, at collector box right side glaze plate, the bottom dress is annotated oil outlet fitting, left side dress relay connector and vacuum butterfly valve, as a whole with fixing between upper barrel body and the lower barrel body, on upper barrel body, adorn cover plate, filter gas box, side charge of oil bit table is put gas and is chewed on membrane vesicle, on membrane vesicle and oil level gauge, adorn support respectively, load bar between two stands.Main points of the present utility model are its structural shape and operation principle.Its operation principle and using method are: oil conservator is used for 11 kilovolts and other transformer of higher level, in the transformer running, because variation of temperature, the volume of transformer oil also changes thereupon, oil-immersed type transformer must be in that soak under the full transformer oil condition just can safe operation, so volume increases when oily temperature rise, unnecessary oil enters Oil Tank by Buchholz relay, oil when oily temperature drop is low in the Oil Tank flows back to by Buchholz relay in the transformer replenishing the oil mass in the transformer, thereby has played the respiration of transformer.Because transformer oil is aging easily, oxidation, suction etc., so the generation of having adopted the cyst membrane structure to solve this type of problem fully as the Oil Tank of breathing owing to adopt multi-sealedly, guarantees that seepage does not take place Oil Tank.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is a structural representation of the present utility model.

With reference to accompanying drawing, whole device is by upper barrel body 2, lower barrel body 16, sealing gasket 15, membrane vesicle 1, venting chews 3, support 4, connecting rod 6, cover plate 5, filter gas box 7, oil level gauge 8, glass plate 9, annotate oil outlet fitting 10, collector box 11, relay connector 12, dirt trap 17, drain plug 18, dividing plate 14, vacuum butterfly valve 13 is formed, dividing plate 14 is installed in lower barrel body 16, on dividing plate 14, add fixedly membrane vesicle 1 of sealing gasket 15, at lower barrel body 16 left surfaces dress drain plug 18, lower left quarter is installed dirt trap 17, at lower barrel body 16 right lower quadrants collector box 11 is installed, at collector box 11 right side glaze plates 9, the bottom dress is annotated oil outlet fitting 10, left side dress relay connector 12 and vacuum butterfly valve 13, sealing gasket 15 is fixing as a whole with adding between upper barrel body 2 and the lower barrel body 16, dress cover plate 5 on upper barrel body 2, filter gas box 7, side charge of oil bit table 8, on membrane vesicle 1, put gas and chew 3, on membrane vesicle 1 and oil level gauge 8, adorn support 4 respectively, load bar 6 between two stands 4.

Hermetically sealed film oil conservater compared with prior art has design science, modern design, technology and closes Reason, dependable performance, cost be lower, do not produce seepage, the advantage such as pollution-free, will be widely used in electromechanics In the industry.
