Abstract
The invention discloses a preloading method of a high-voltage and low-voltage insulation tube of a three-dimensional rolling iron core dry type transformer. The preloading method comprises the following steps that: firstly, a low-voltage coil is wound on an iron core; after the low-voltage coil wounding is completed, a polyester film is directly rolled into the insulating tube at the outer side of the low-voltage coiling, the lap joint part of the insulating tube is glued by high-temperature-resistance double faced adhesive tapes, and the relative fixation of the insulating tube and the low-voltage coiling is maintained; a high-voltage coil inner mold is arranged at the outer side of the insulating tube, and a high-voltage coiling is wound; and the mold filling is carried out after high and low voltage demolding, and the insulating tube is directly left between the high-voltage coil and the low-voltage coil, and the high-voltage and low-voltage insulation tube of the three-dimensional rolling iron core dry type transformer is obtained. The method has the advantages that the material of the ordinary dry type transformer insulating tube is adopted, the insulating tube is preloaded in the coil winding process, the work efficiency is greatly improved, and the production cost is saved.
Description
Technical field
The present invention relates to a kind of three-dimensional coil iron core dry-type transformer, the preassemble method of insulating cylinder between specifically a kind of three-dimensional coil iron core dry-type transformer high-low pressure.
Background technology
As a kind of novel distribution transformer, three-dimensional coil iron core dry-type transformer becomes a kind of trend of distribution transformer with its pair energy-saving advantages.But with respect to common dry-type transformer, its coil winding is accomplished on the iron core of sealing, and Fig. 1 is that three-dimensional coil iron core dry-type transformer coil winding is in sealing sketch map unshakable in one's determination.Among Fig. 1, the 11st, high-voltage coil and low-voltage coil, the 12nd, unshakable in one's determination.Insulating cylinder between the high-low pressure then must add after the whole moulding of coil again.Now three-dimensional volume iron core is done the manufacturer that becomes and is all adopted and make two semicircle insulating cylinders and add the main aperture roads, the interface that bonds again mode, the method efficient is low, insulating cylinder must be made specially, cost is higher.
