Abstract

The present invention provides a manufacturing method of transformer by simply engaging the each separate layers of insulation paper to simplify manufacturing transformer process. The method includes the following steps: inserting the transformer coil unit (230) into the inner of E-type core (210), fixing I-type core (220) by welding or engaging on it, engaging the bracket for using to install other equipments to E-type core (210) or I-type core (220), and coating insulation paper (240) on both sides of the longitudinal direction of the transformer coil unit (230) in order to insulate between the transformer coil unit (230) and E-type core, said insulation paper (240) disposed corona-resistance but correspondingly not scribe resistance mica (242), and integrated engaging polyaromatic amide (244) which is not corona-resistance but scribe resistance compared with mica (242) on the two sides of said mica with adhesive.

Description

The manufacture method of transformer

Technical field

The present invention relates to transformer, specifically, relate to the manufacture method that when being assembled into transformer coil unit on the iron core, makes the transformer that insulate between them.

Background technology

As shown in Figure 1, usually, high-tension transformer 100 is devices that are used to produce high pressure that the magnetic amplifier of microwave oven etc. needs the equipment of high pressure to be suitable for.One-level coil and the turn ratio secondary coil bigger than this one-level coil is set respectively on the E core 110 of this high-tension transformer 100, and in the bottom of E core 110 the fixing I sections heart 120, be fixed for being installed to carriage on other equipment in the welding of the bottom of the I sections heart 120.At this moment, on the one-level coil, fixedly be applied in the power input terminal of alternating current, and connect the high-tension bus-bar that is connected with load in the end of secondary coil, thereby can be with the high voltage transfer that produces by the mutual inductance effect between one-level coil and the secondary coil to load.

As mentioned above, in transformer 100,, then, can on secondary coil, induce high-tension electricity according to the turn ratio of one-level coil and secondary coil if apply commercial voltage to the one-level coil.

Especially, on described secondary coil, induce the high voltage more than the 2000V, thus between each coil and each iron core by insulating paper by electric insulation.

As shown in Figure 3, described insulating paper 140 constitutes by three layers, wherein, uses anti-corona in the centre but the mica 142 of non-scratch-resistant, and use not anti-corona but the Nomex (nomex) 144 of scratch-resistant, thereby overlayed on the transformer coil unit with complementary relationship on the two sides of this mica 142.

But, because described insulating paper 140 is covered on the transformer coil unit layer by layer discretely successively, so there is the problem that transaction capabilities descends when making transformer.

Summary of the invention

The present invention makes in order to address the above problem, and its purpose is to provide a kind of manufacture method of transformer, and this method engages simply by the insulating paper with each layer separation, can simplify the manufacture process of transformer.

The present invention to achieve the above object; A kind of manufacture method of transformer is provided; The method comprises following process: the inside that the transformer coil unit that coiling is formed inserts E core; Fix the I iron-core by welding or mould assembly thereon; To be attached to E core or I iron-core be used to the carriage that is installed on other equipment; And for described transformer coil unit and E core are insulated mutually; Coating insulating paper on the two sides of the length direction of described transformer coil unit; The method is characterized in that

Described insulating paper disposes mica therebetween, the anti-high-voltage corona that produces down in high pressure of this mica, but the not anti-scraping that when handling, takes place, and the two sides at this mica engages Nomex integratedly by binding liquid, this Nomex is compared relatively anti-inadequately corona with mica, but the anti-scraping that when handling, takes place.

The invention effect

The present invention is layed onto mica on the transformer coil unit to engage the all-in-one-piece state with Nomex, and therefore, with first lining Nomex and cover thereon after the mica, the process in the past that covers Nomex is more thereon compared, and can reduce process number.And, can solve most of on job behavior is the overwrite procedure of the insulating paper of handwork, the position of the insulating paper that produces in the process of mica and Nomex of promptly being covered respectively moves, and the problem of the defective insulation that causes thus and insulating paper breakage etc., and because the minimizing of worker ordinal number and can improve transaction capabilities and productivity ratio.

Embodiment

Below, based on accompanying drawing embodiments of the present invention are described.

As shown in Figure 2, transformer has the transformer coil unit 230 of reeling and forming, and on the both sides of the length direction of this transformer coil unit 230, be coated with insulating paper 240, this insulating paper 240 is used for when this transformer coil unit 230 is inserted into the inside of E core 210, and transformer coil unit 230, E core 210 and E core 210 and the contact portion of the I sections heart 220 are insulated.

As shown in Figure 4, insulating paper 240 constitutes by three layers, wherein, form the mica 242 of the corona of the anti-high heat that under high pressure, produces in the centre, and engage Nomex 244 by binding liquid on the two sides of this mica 242, this Nomex 244 is compared relatively anti-inadequately corona with mica 242, thus but easily processing of scratch-resistant.That is, insulating paper 240 have with the mica 242 of anti-thermal loss in corona with engage the complementary structure that forms because of tractable Nomex 244 such as scratch-resistants.

As mentioned above, additionally be ready in advance engage the insulating paper 240 that Nomex 244 constitutes one with the manufacturing of transformer coil unit 230 by two sides at mica 242, and in the previous stage that transformer coil unit 230 is inserted in the iron core, the described insulating paper 240 that is covered is so that upper surface, lower surface and the side of its parcel transformer coil unit 230.Afterwards, use adhesive tape etc. that insulating paper 240 is fixed on the transformer coil unit 230.

Claims

1. the manufacture method of a transformer, comprise following process: the inside that the transformer coil unit that coiling is formed inserts E core, fix the I sections heart by welding or mould assembly thereon, carriage on other equipment be will be used to be installed to and E core or I sections will be attached in the heart, and for described transformer coil unit is insulated mutually with E core, the insulating paper that is covered on the two sides of the length direction of described transformer coil unit the method is characterized in that

Described insulating paper disposes mica therebetween, the anti-high-voltage corona that produces down in high pressure of this mica but the not anti-scraping that when handling, takes place, and the two sides at this mica engages Nomex integratedly by binding liquid, this Nomex is compared relatively anti-inadequately corona with mica, but the anti-scraping that when handling, takes place.
