Description
Technical field
The utility model relates to the on-line automatic gas and oil separating plant of a kind of oil-filled transformer, is applicable to online Oil-gas Separation in the transformer oil dissolved gas on-line monitoring system.
Background technology
Routine Test Lab transformer oil dissolved gas chromatography experiment must be carried out this link of the degassing in the oil earlier, promptly extract the oil sample of certain volume from on-the-spot transformer, get back to and utilize special degasser that gas is spun off from transformer oil in the laboratory earlier, could analyze experiment gas.
Patent ZL92240649.9 oil-filled transformer automatic deaerating device purposes is to remove the transformer oil dissolved gas, and the gas that device takes off directly enters atmosphere and do not collect, and can not use as gas sampling for the gas analysis test.
The gas penetrant of the Oil-gas Separation mechanism in patent ZL1266988A dissolved gas on-line intelligence monitoring, diagnosing method and the device is mainly by gas-permeable membrane be clipped in a film left side, the stiffening plate of right both sides constitutes, when Oil-gas Separation mechanism is installed in the transformer, during lower position, permeable membrane in the Oil-gas Separation mechanism will bear certain pressure, stiffening plate in the mechanism is played a supporting role to ventilated membrane, its side must closely pasted ventilated membrane, the ventilated membrane that is used for the Oil-gas Separation effect is generally comparatively soft, because the existence of rigid material stiffening plate is arranged, sealing between ventilated membrane edge and the Oil-gas Separation mechanism goes wrong when mounted easily, the oil impregnate phenomenon often occurs between ventilated membrane edge and the Oil-gas Separation mechanism.Stiffening plate is in order there to be diameter 5mm through hole above ventilating in addition, when there is oil pressure the outside, to bear bigger pressure than other parts on the ventilated membrane in the through hole scope, after installation, must cause the distortion of ventilated membrane, time has been grown easy destruction film, thereby influences the service life of ventilated membrane.
Adopt vavuum pump degassing mode automatic deaerating device in the past, can not preserve the gas sample, bulky.Adopt the Oil-gas Separation film device employing ventilated membrane of ventilated membrane degassing mode and the mounting means that stiffening plate is close in the past, thereby ventilated membrane easy deformation reduction of service life, the oil impregnate phenomenon does not with great difficulty appear in the film edge sealing, adopt separate type ventilated membrane mounting means in addition, the thickness of film is very limited, make the device degassing efficiency not high, the gas and oil equilibration time is longer.
Summary of the invention
Technical problem: the purpose of this utility model provides the on-line automatic gas and oil separating plant of a kind of oil-filled transformer, the degassing must be by manually carrying out in the solution past transformer oil, and the problem of the oil dissolved gas of can not extracting online, automatically, has continuously particularly solved requisite on-line automatic Oil-gas Separation link in the transformer oil dissolved gas on-line monitoring system.
Technical scheme: the utility model solves the technical scheme that its technical problem adopts and is: gas-permeable membrane and original stiffening plate are processed as one, make composite membrane, simultaneously the through-hole aperture that is used to breathe freely in the stiffening plate of band micropore is dwindled, increase the microporosity on the unit are, improve gas infiltration efficient.
Its concrete structure is: this device is by composite membrane, hollow base, closing cap on the air chamber, the stiffening plate of band micropore is formed, ventilative rete is compound with the metal reinforcement plate of band micropore to be one, form composite membrane, this composite membrane is embedded on the interior step of the interior hollow base of hollow base, closing cap and hollow base match on the air chamber, bulge loop on the air chamber on the closing cap embeds in the interior step of the interior hollow base of hollow base, and be pressed on the composite membrane, form the infiltration air chamber by the space between the closing cap on composite membrane and the air chamber, the top of closing cap also is provided with the gas collecting mouth on air chamber, is connected and fixed by hold-down screw between the closing cap on hollow base and the air chamber.
Beneficial effect: the beneficial effects of the utility model are, the degassing must be by manually carrying out in the past transformer oil, when laboratory will carry out the Gas in Oil of Transformer analysis, must be by the professional to the on-the-spot transformer oil of fetching certain volume earlier of transformer operation, get back to behind the laboratory with being kept in certain airtight container after the specialized equipment degassing, again gas is extracted from container and inject analytical instrument and test.The present invention makes transformer oil this link that outgases can't help manually to finish, the on-line automatic gas and oil separating plant oil dissolved gas of can extracting online, automatically, continuously.In the time will carrying out the Gas in Oil of Transformer analytical test, the gas sample that can directly extract in the separator is tested, and outgases without manually-operated.
In now more and more transformer oil dissolved gas on-line monitoring systems that use, degassing link must be finished and can not be with manually controlling automatically in the oil.On-line automatic gas and oil separating plant has just solved such problem, and the gas automatic sampling module of on-line monitoring system on the gas outlet termination of handle assembly can be implemented in requisite gas automatic deaerating and sample introduction link in the line monitoring system.
Compare with former vavuum pump degassing mode automatic deaerating device, can not preserve the gas sample and can not do the problem that analytical test is used thereby the utility model has solved vavuum pump degassing mode automatic deaerating device.Compare with the Oil-gas Separation film device that adopted ventilated membrane degassing mode in the past; the utility model adopts the composite membrane mounting means; the stiffening plate and the integrated processing of ventilated membrane of band micropore; solve ventilated membrane and stiffening plate and be installed separately the easy oil impregnate problem in edge; the stiffening plate through hole of the band micropore in the composite membrane is littler with comparing the aperture in the past simultaneously; when suitable gas molecule sees through ventilated membrane is played better support and protective effect, solved the problem that the ventilated membrane distortion damages easily.Ventilated membrane in the composite membrane is compared with independent ventilated membrane of past in addition, very thin thickness, and microporosity improves, and gas infiltration efficient is significantly improved.After tested, the online gas and oil separating plant that adopts the stiffening plate of independent ventilated membrane and diameter phi 5mm band micropore to cooperate realization is installed gas in 48 hours air chambers of 25 ℃ of needs reaches balance.Adopt this to be suitable for novel device under same experiment condition, the gas balance time shortens to 10 hours.
