Description
Technical field
The utility model belongs to transformer breather technical field, especially relates to a kind of self-sealing bitubular transformer and exhales
Haustorium.
Background technology
Respirator is one attached safety guard of transformer, be installation for transformer air chamber exchanged with ambient atmos must
Through barrier, inside is filled with adsorbent such as silica gel-type activated alumina.Respirator mainly has two aspect functions：One is to make transformation
Air and extraneous UNICOM in device device body.During transformer station high-voltage side bus, heating oil volume expansion breathes out internal gas；Transformer cools, oil
Volume contraction, sucks extraneous air, and retainer body inner and outer air pressure is equal.Two are absorbed by the built-in adsorbent drier of respirator
Air moisture；Humid air is prevented to be directly entered conservator, reduction or destruction oil-insulation intensity.When under transformer temperature reduction oil level
Drop, transformer sucks gas by respirator, and gas first passes through oil sealing, the i.e. lubricating cup equipped with transformer oil.Oil sealing filters out sky
Dust impurity in gas, becomes clean gas.
Because respirator is typically exposed to outdoor, running environment is severe；By long-play, occur silica gel deliquescence and become
Color, it is therefore desirable to replacing processing irregularly is carried out to the silica gel in respirator.
At present, substation field is changed respirator silica gel and carried out by following flow：Grave gas protection is disabled to scheduling application；
Respirator is pulled down from connecting leg；Connecting leg end banding is prevented into transformer resorption air with plastic cloth；Change respirator interior
Silica gel；Remove the plastic cloth for being enclosed in connecting leg end；Respirator is installed；Application scheduling input grave gas protection.
Grave gas protection is for reflecting the various failures of inside transformer and acting on the important guarantor of circuit breaker trip rapidly
Shield.Its principle is：During power transformer interior fault, tank internal pressure steeply rises, and big gauging stream pours into installation for transformer, weight
Now oil flows flow velocity for protection measurement, and circuit breaker trip is acted on when more than setting valve.
When changing respirator silica gel, in order to prevent conservator resorption air, it is necessary to which connecting leg is temporarily blocked.Become during this period
Depressor internal pressure can not keep balance with ambient atmosphere pressure, if not disabling grave gas protection, be arranged when removing connecting leg closure
Shi Shi, it is more likely that cause inside transformer pressure to discharge suddenly, causes grave gas false protection, and consequence is hardly imaginable.
However, the reliability of tranformer protection can be reduced by exiting grave gas protection.Once there is power transformer interior fault change
Depressor can not trip in time, can expand accident impact scope.Therefore, maximum in existing replacing respirator silica gel flow the drawbacks of, is just
It is that must disable grave gas protection.
Scheduling approval must be obtained due to disabling grave gas protection, many operation maintenance personnels are operated against regulations, i.e., to follow the line of least resistance
Connecting leg is not blocked after removing respirator, keep oil tank of transformer internal and external pressure balance in order to avoid disabling grave gas protection.This
Plant way extremely inadvisable, because all having installed capsule or barrier film inside even many installation for transformer, farthest subtract
Lack the contact area of transformer oil and air, but either capsule or barrier film are impossible to definitely tight, the not company of closure
Pipe can cause the quality serious deterioration of transformer oil.
In addition, respirator connecting leg directly can connect with air for some time during existing transformer breather changes silica gel
It is logical, the performance of transformer oil can be being influenceed to a certain degree.
Therefore being needed badly among prior art wants a kind of new technical scheme to solve this problem.
Utility model content
Technical problem to be solved in the utility model is：A kind of self-sealing bitubular transformer breather is provided to be used for solving
There is potential safety hazard in terms of grave gas protection when changing respirator silica gel in transformer breather of the prior art；Prior art
In transformer breather respirator connecting leg can for some time directly and atmosphere during silica gel is changed, can be certain
The technical problems such as the performance of degree influence transformer oil.
Self-sealing bitubular transformer breather includes respirator connecting leg flange, three connecting pipes, self-styled valve, dead lock, silicon
Glue tank and oil sealing cup, one end of the respirator connecting leg flange is fixedly connected with respirator connecting leg, respirator connecting leg flange it is another
One end is fixedly connected with a port of three connecting pipes；Two other port of three connecting pipe is arranged on the interior of dead lock
Portion, two ports of three connecting pipe are connected with silica gel tank respectively；The oil sealing cup is fixedly mounted on the bottom of silica gel tank.
The quantity of the silica gel tank is two.
The quantity of the oil sealing cup is two.
By above-mentioned design, the utility model can bring following beneficial effect：
1st, the utility model is designed using the double respirator silica gel tanks of the bitubular, and the silica gel in two silica gel tanks is changed successively.When
When removing one of silica gel tank, another silica gel tank normal work, it is not necessary to by whole respirator connecting legs block, from without
Grave gas protection is disabled with regard to respirator silica gel can be changed；Safe operation without influenceing transformer；
2nd, silica gel tank connects self-styled valve, when removing silica gel tank, valve automatic plugging, is exhaled in Renewal process removing
Will likely will not resorption air with the respirator connecting leg self-closed that contact of the external world, respirator connecting leg while haustorium, it is ensured that change
Depressor conservator will not resorption air；
3rd, realize that two silica gel tanks can not be while remove, when removing one of silica gel tank using dead lock, dead lock
Can be stuck by another silica gel tank, it is ensured that do not result in whole respirator connecting legs and block, so as to ensure inside and outside oil tank of transformer
Pressure balance.
