Referring to Fig. 1, existing illustrate to transformer breather provided by the invention.Transformer breather, including for
Deposit the silica gel cylinder 1 of silicon particle, the upper lid 2 located at the upside of silica gel cylinder 1, the breathing disk 3 located at the downside of silica gel cylinder 1 and located at exhaling
The inner side lubricating cup 41 and outside lubricating cup 42 that are used to deposit transformer oil of the downside of sucker 3, it is characterised in that also include being fixed on exhaling
The extension lubricating cup 43 that is upside and being connected with inner side lubricating cup 41 of sucker 3 and it is used for support silicon located at extension lubricating cup 43 upside
The separation net 5 of micelle, separation net 5 are located at the inside of silica gel cylinder 1, and separation net 5 is set in distance with extension lubricating cup 43, extends lubricating cup
The area of 43 cross section is more than the area of the cross section of inner side lubricating cup 41.
The present apparatus in silica gel cylinder 1 by setting separation net 5 to deposit in silicon particle between lid 2 and separation net 5, in silicon
The fixed extension lubricating cup 43 connected with inner side lubricating cup 41, extension in cavity volume between the separation net 5 of the bottom of packing element 1 and breathing disk 3
Lubricating cup 43 functions simultaneously as the effect of spiracle, and prior art increase is compared in spiracle aperture, when the transformer oil oil level in lubricating cup
When the volume of rising and transformer oil exceedes the volume of inner side lubricating cup 41, transformer oil can be flowed into extension lubricating cup 43, and increase becomes
The flowing space of depressor oil, prevents transformer oil and silica gel contact stain, causes respirator function to fail, the height of separation net 5
More than extension lubricating cup 43 height, equally play prevent because hydraulic press oil raise splash and caused by silica gel pollute.
Extension lubricating cup 43 is formed in one with inner side lubricating cup 41.It can be split type or one to extend lubricating cup 43 and inner side lubricating cup 41
Body formula, the unlimited set-up mode processed of apparatus of the present invention.
The lubricating cup hole 31 for being used for lubricating cup 41 on the inside of fixed, aperture and the inner side lubricating cup 41 in lubricating cup hole 3 are provided with breathing disk 3
External diameter be adapted.Spiracle on present apparatus breathing disk 3 is the internal holes of the inner side lubricating cup 41 and extension lubricating cup 43 that are connected,
The aperture increases of spiracle compared with breathing the spiracle on disk 3 in the prior art, when the oil level of transformer oil steeply rises,
It will not can be realized including transformer oil because the situation for the transformer oil splash that oily channel size reduces suddenly and occurs, the present apparatus
Side lubricating cup 41 and the slow rising in extension lubricating cup 43.
The volume sum of inner side lubricating cup 41 and extension lubricating cup 43 is more than the volume of outside lubricating cup 42.To ensure transformer oil not
The outside of extension lubricating cup 43 can be flowed out, need to ensure that inner side lubricating cup 41 is more than the oil mass of transformer oil with extending the volume of lubricating cup 43, this
Device sets inner side lubricating cup 41, and reserve level is floated remaining with extending volume of the volume more than outside lubricating cup 43 of lubricating cup 43
Amount, fully ensure that transformer oil will not flow out outside extension lubricating cup 43.
Projection of the inner side lubricating cup 41 on breathing disk 3 falls into extension lubricating cup 43 within the projection on breathing disk 3.Extension oil
The bore of cup 41 need to be more than the bore of inner side lubricating cup 41, ensure transformer oil when entering extension 43 inside of lubricating cup, flowing is slow
It will not occur drastically to rock or raise to splash.
It is in back taper to extend lubricating cup 43, and the arrival end of extension lubricating cup 43 is fixedly connected on the upper end of inner side lubricating cup 41, extension
The flared end of lubricating cup 43 is directed upwards towards separation net 5.It can be column or this implementation that diameter is more than inner side lubricating cup 41 to extend lubricating cup 43
Back taper in example, the present apparatus are not limited to the form for extending lubricating cup 43.
Separation net 5 is in the taper of point upward, and screen pack 5, silica gel cylinder 1 form the accommodating chamber of storage silicon particle with upper lid 2.
Compared in the prior art, silicon particle is placed directly on breathing disk 3, and the separation net 5 in the present apparatus is certain higher than extension lubricating cup
Highly, fully ensure that transformer oil will not pollute silicon particle and the blocking of mesh will not be caused by transformer oil.
Separation net 5 is provided with some mesh for ventilating air, and the aperture of mesh is less than silicon particle diameter.
The snap joint for being used for connecting oil conservater is provided with the upper end of upper lid 2.In the prior art usually using ring flange with
The mode of rubber blanket carries out the connection and sealing of respirator and oil conservater, but rubber blanket aging can cause respirator poorly sealed
The problem of, ring flange corrosion not only results in the problem of poorly sealed, also results in the problem of respirator can not dismount；The present apparatus
Using the connected mode of snap joint, sealing is tight, and the connectivity problem caused by corrosion will not occur.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
