Vegetables oil after extraction deacidification adds in retort I 22 from vegetables oil filling tube II 24; Then water-bath I 21 heating in water bath distillations, evacuator I 23 extracts a small amount of extraction agent and the moisture that is slightly soluble in vegetables oil simultaneously.
3) mix insulation oil preparation facilities 3 is prepared mix insulation oil
Vegetables oil after purification adds in mixing tank 31 from vegetables oil filling tube III 34, and mineral oil adds in mixing tank 31 from mineral oil filling tube 33, oxidation inhibitor can be dissolved in a small amount of mineral oil simultaneously, adds together mixing tank 31; Then turn on agitator II 32 stirs, and vegetables oil obtains mix insulation oil after fully mixing with mineral oil.
4) mix insulation oil distilation device 4 purification mix insulation oil
Mix insulation oil adds in retort II 42 from mix insulation oil filling tube I 44; Then water-bath II 41 heating in water bath distillations, evacuator II 43 extracts in mix insulation oil simultaneously a small amount of steam and extraction agent.
5) the mix insulation oil after purifying is squeezed into the 5 interior sealings of mix insulation oil seal container by mix insulation oil vomit pipe II 45 and is preserved.
The vegetables oil using in the present invention can be selected rapeseed oil, sunflower seed oil, olive wet goods, preferably olive oil; Mineral oil can be selected the transformer oil of the multiple trade mark.
Take industrial sweet oil (chemical pure) and 25# transformer oil is raw material, the dehydrated alcohol of solvent selection 99.7%, sweet oil mixes with the volume ratio of 20:80 with mineral oil, and added the antioxidant (T501 and L06 respectively account for 0.3%) of mass percent 0.6%, the mix insulation oil leading indicator of production is as follows:
The parameters of the mix insulation oil that the present invention produces all meets the requirement of transformer oil technological standard GB 2536-90; Between 20 ℃～90 ℃, this oily kinematic viscosity and mineral oil are almost equal; In 30～106Hz range of frequency, this oily relative permittivity remains constant substantially, and more bigger than the relative permittivity of mineral oil; This oily frequency breakdown voltage (58kV) is far above mineral oil (35kV); Its biological degradability is obviously better than mineral oil.
In order to verify the antiageing effect of mix insulation oil, two groups of mineral oil-paper insulation samples and mixing oil-paper insulation sample are placed in respectively to 90 ℃, 110 ℃ ageing ovens, carry out the accelerating thermal aging test of 184 days by a definite date, and by certain time interval, parameter measurement is carried out in sampling.Test-results is as follows: the insulation paper polymerization degree in mix insulation oil of the present invention is apparently higher than the insulation paper polymerization degree (approximately exceeding 150-170) in mineral oil; The furfural content producing in mix insulation oil is lower than furfural content in mineral oil; The speed of the low molecular acid content in mix insulation oil-paper insulation system and generation low molecular acid is all significantly less than mineral oil-paper insulation system.Many-sided characteristic shows that the anti-aging mix insulation insulation paper oily and its infuse that the present invention produces has dual resistance of aging, i.e. the mix insulation oil that the present invention produces has the aging effect of good inhibition insulation paper.
In sum, the present invention can be on a large scale, mix insulation oil is produced in enormous quantities, serialization, realized the suitability for industrialized production of mix insulation oil, and the mix insulation oil flash point of producing is high, antioxidative stabilizer is strong, also can suppress the aging of transformer insulating paper, there is transformer oil and the anti-aging effect of oil-paper insulation system doubling simultaneously.
Finally explanation is, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although by with reference to the preferred embodiments of the present invention, invention has been described, but those of ordinary skill in the art is to be understood that, can to it, make various changes in the form and details, and not depart from the spirit and scope of the present invention that appended claims limits.
