Description

A kind of transformer oil storage of readily identified oil level

Technical field

The utility model relates to the safety guard of power transformer, especially a kind of transformer of readily identified oil level Oil conservater is suitable for vertical external oil storage case for transformer.

Background technique

Currently, capsule-type or diaphragm type in existing transformer oil storage, since its material capability is bad or adhesive technology It is unqualified, the phenomenon that causing bonding not tight enough, frequent occurrence aging cracking, transformer oil quality deterioration and leakage of oil can be generated. And existing wavy metal sealed Oil Tank, it is found by operative practice in the past few years, there is also many more outstanding Problem.Oily vertical structure oil conservater in such as, metal bellows is longitudinal movement, certainly exists in ripple closure and does not participate in benefit The region of bypassed oil (account for about total compensation rate 14% or more) repaid；Also, because of the oil for installing constant weight in its ripple, it is easy to cause gold Belong to bellows deformation, bulge, spalling when serious.These problems will have a direct impact on the operational safety of transformer.And the outer horizontal knot of oil Structure oil conservater, metal bellows are transverse movements.It is uneven because being pressurized, it is also easy to happen catching phenomenon, gas relay is caused to miss Movement.And increasing guide wheel can be such that region of bypassed oil increases, and oil level instruction has error, have an effect on its compensating action brought into normal play, Hidden danger is brought to the safe operation of power transformer.

Summary of the invention

The purpose of the utility model is to provide a kind of transformer oil storages of readily identified oil level, solve traditional transformer Outer oil oil conservater fuel quantity compensator setting is unreasonable, and region of bypassed oil is excessive, and metal bellows is easy to damage, and oil level is not easy to accurately identify The problem of, structure design is more reasonable, can increase compensation rate, fuel-economizing, oil level instruction is more intuitive, obvious, accurate, further Improve the reliability of oil conservater safe operation.

The technical scheme adopted by the utility model is the device includes with sealing cabinet lid, bottom of cabinet disk, cabinet body and assembling Rectangular box FlexbleJoint in it, FlexbleJoint upper sealing plate are fixed in cabinet body, the periphery of sealing plate under FlexbleJoint Directive wheel along the longitudinal movement of cabinet body inner wall is set, and bottom of cabinet disk is provided with oil transportation mouth and oiling for connecting oil tank of transformer Mouthful, have technical point that the FlexbleJoint upper sealing plate is packaged on the annular seal flange of cabinet body upper inside wall, it will be in cabinet body It is divided into upper chamber and lower chambers, cabinet body is provided with exhaust pipe and respiratory siphon, and exhaust pipe upper port is connected to outside cabinet body, exhaust pipe Lower port passes through annular sealing flanges and is connected to lower chambers；Respiratory siphon upper port is connected to upper chamber, and breathing infratubal port is pierced by bottom of cabinet Disk；FlexbleJoint upper sealing plate is provided with the compensator venthole of connection upper chamber and FlexbleJoint inner cavity chamber, respiratory siphon Upper port is connected to compensator venthole by upper chamber；Sealing plate, which is provided with, under the FlexbleJoint stretches to cabinet body wall oil level sight window Oil level indicating arm, oil level indicating arm front end, which has, adjustably adjusts bar, adjusts boom end and has strong magnetic idler wheel, breaks away outside oil level sight window Slot is provided with the magnetic instruction terminal with strong magnetic idler wheel magnetic suck.

The magnetic instruction terminal is with the outer magnetic rollers for applying chromatograph.

The good effect that the utility model has is: due to the utility model oil conservater combine existing transformer with it is vertical outside The advantages of oily oil conservater, for its there are the shortcomings that redesigned, compensator venthole is close by upper chamber and cabinet body The respiratory siphon sealed on flange forms connection, breathes outside infratubal port sealing-in bottom of cabinet, upper chamber can be made to be connected to outside air；In Cabinet body, the venthole of the other end and the sealing flange on cabinet body top are stretched out in sealing-in exhaust pipe on the close flange of cabinet body, exhaust pipe one end Fixed sealing-in, formation are connected to lower chambers, lower chambers can be made to be connected to outside air, keep structure more reasonable；Lower sealing plate is set The oil level indicating arm set, which has to adjustably adjust bar, strong magnetic idler wheel and side chute magnetism is arranged outside oil level sight window, indicates terminal, Can make magnetic instruction terminal and the holding of the resistance of strong magnetic idler wheel customer service oil synchronize move up and down, be easy to Observation personnel and directly observe Monitoring guarantees equipment safety operation, so the design of its structure is more reasonable, not only increases compensation rate but also thoroughly eliminates existing The operational safety of power transformer is influenced present on similar oil storage cabinet, really realizes the anti-corrosion protection to transformer oil, Oil level instruction reaches intuitive, hence it is evident that accurately further increases the reliability of equipment safety operation.
