Abstract
The invention relates to a winding insulation cardboard tube and a production process thereof, as well as an oil immersion drum for the production process. The production process comprises the following steps of: firstly, putting the prepared cardboard cylinder into the oil immersion drum for oil immersion for 3 hours; secondly, taking out and draining the cardboard tube from the oil immersion drum; and finally, packaging the drained cardboard tube by using a plastic cloth and a sealing band and vertically storing the drained cardboard tube in an insulated drying room. Since the winding insulation cardboard tube provided by the invention is subjected to the oil immersion treatment, so that not only can the insulation property of the transformer be effectively improved, but the short-circuit resistance of the transformer can be enhanced, and the dielectric and electromechanical property can be improved.
Description
Technical field
The present invention relates to a kind of winding insulation cardboard cylinder and production technology thereof, belong to transformer parts technical field.
Background technology
At present, when the transformer coiling, the use of insulation cardboard cylinder can effectively increase mechanical strength, cuts off the conduction foot bridge, has improved the transformer anti-short circuit capability, prevents winding deformation.Though exterior loop receives coil when short circuit is tensile stress, and paper web has been arranged, coil circularity is better relatively, can reduce the probability that coil damages, and has the coil of insulation cardboard cylinder guaranteed near internal coil diameter side oil duct size.Because cellulose has very strong affinity to water, the water absorbing capacity of paper web is more much bigger than oil, and the moisture that is made in the initial stage oil that puts into operation at transformer will have a process that in paper, shifts; The content of moisture in paper become hundred times greater than the content in oil, and because the water absorbing capacity of this paper web is strong, waterproof ability reduces; Therefore yielding; And the existence of moisture and in oilpaper uneven distribution can have a strong impact on transformer operation, thereby make the paper web easy of crack, it is too many that dielectric constant differs; Non-uniform electric has strengthened breakdown strength and creepage distance.
Summary of the invention
The present invention is directed to the deficiency of the problems referred to above, propose a kind ofly to improve transformer insulated property, can strengthen transformer anti-short circuit capability winding insulation cardboard cylinder and production technology thereof and be used for the immersion oil bucket of this technology.
The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of winding insulation cardboard cylinder, and this winding insulation cardboard cylinder is used for Transformer Winding, and said winding insulation cardboard cylinder is the cardboard cylinder of handling through immersion oil.
A kind of production technology that is used to produce above-mentioned said winding insulation cardboard cylinder may further comprise the steps: the first step, splendid attire insulating oil in the immersion oil bucket; In second step, the cardboard cylinder of having made was put under the immersion oil bucket pasta immersion oil 3 hours; The 3rd step, cardboard cylinder is taken out from the immersion oil bucket, drain; The 4th step, the cardboard cylinder that drains is sealed with Polypropylence Sheet and sealing tape, erect and leave in the insulation drying room.
Further: be placed with silicon particle in the said insulating oil.
A kind of immersion oil bucket that is used for winding insulation cardboard cylinder production technology comprises chassis, bucket wall, and said bucket wall is arranged on the chassis; Said bucket wall lower end is provided with gate valve; And bucket wall upper end is provided with hanger, and said bucket wall top is provided with flange, and this flange is used to prevent a barrel wall distortion.
Further: also comprise base, said chassis is arranged on the base.
Again further: also comprise suspender, said suspender comprises two orthogonal channel-section steels of dividing equally, and the two ends of arbitrary channel-section steel in these two channel-section steels are respectively arranged with suspension hook.
Winding insulation cardboard cylinder of the present invention and production technology thereof are compared prior art, have following beneficial effect: because the winding insulation cardboard cylinder is handled through immersion oil; Therefore can effectively improve transformer insulated performance; Strengthen the anti-short circuit capability of transformer, and improve dielectric and electricapparatus performance, the winding insulation cardboard cylinder can not ftracture and can not be out of shape simultaneously; Because the molten outlet capacity of insulating oil is lower, water absorption rate has substantial degradation in transformer making and running.Owing to the cardboard cylinder that drains is sealed with Polypropylence Sheet and sealing tape, erect and leave in the insulation drying room, so the winding insulation cardboard cylinder can be prevented the distortion of making moist.Because insulating oil can absorb airborne water, and silicon particle is put into insulating oil, this silicon particle can absorb water effectively, therefore can reduce the content of insulation W/O, has guaranteed the immersion oil effect of winding insulation cardboard cylinder.
