Abstract
The invention relates to an insulation bandaging process of an electric motor winding lead wire connector. The insulation bandaging process of the electric motor winding lead wire connector comprises a silicon rubber insulation mud filling, a sealant filling and an insulation bandaging. The silicon rubber insulation mud is used for filling groove steps produced through welding and overlap joint after welding the lead wire connector, and then the sealant is used for strengthening filling, bare parts without insulating layers in a welding area are wholly outer packed by half folding a self-adhesion type silicon rubber tape and a double glass mica powder center rubber tape 5446-2 three times, and half folding a polyester heat contraction band one time. Through the insulation bandaging process, the insulation bandaging process of the electric motor winding lead wire connector enables the electric motor winding lead wire connector welding position to be good in integral insulation property and waterproof property, capable of avoiding insulation weak spots and suitable for insulation bandaging of the electric motor winding lead wire connector.
Description
Technical field
The present invention relates to motor manufacturing technology, particularly a kind of insulating wrapping technique of electric machine winding lead wire joint.
Background technology
The electric machine winding lead wire joint carries out insulating wrapping to exposed part after welding, often have following problem: there is the insulation weak spot in the welding position behind insulating wrapping, the integral waterproofing poor-performing, and this will bring certain hidden danger of quality to product.
In the prior art, application number is 200710017004.0 Chinese invention patent shielding and the insulating treatment method of place " a kind of transformer coil lift one's head ", application number is 201110202284.9 Chinese invention patent " insulation manufacturing method for wind driven generator ", application number is 201110352379.9 Chinese invention patent " a kind of method for molding end nose part insulators of stator coil of generator ", application number is that the prior aries such as Chinese invention patent " inductive coil insulating treatment of vacuum furnace " of 200610161594.X have all been done certain improvement to the method that relates to insulation, but all can not solve the rear technical problem that has the insulation weak spot of electric machine winding lead wire welding.Therefore, how to realize that electric machine winding lead wire joint insulation property behind insulating wrapping are good, water resistance well becomes the problem that needs solve.
Summary of the invention
Technical problem to be solved by this invention provides a kind of insulating wrapping technique that can realize the electric machine winding lead wire joint that electric machine winding lead wire splice insulation function admirable, water resistance are good, and it can solve there is the weak spot that insulate afterwards in the electric machine winding lead wire joint that exists in the prior art in welding technical problem.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
Described motor winding draws the insulating wrapping technique of joint, comprises the steps:
(1) silicon rubber insulation mud is filled: after finishing lead wire joint welding cleaning, use silicon rubber insulation mud to be filled in the groove ladder place that welded lap produces;
(2) sealant is filled: after silicon rubber insulation mud is filled, re-use sealant zone, cable joint and the former outsourcing insulating regions of lead wire joint between lead wire joint and the cable insulation are filled;
(3) insulating wrapping: do not have the exposed position of insulating barrier whole with adhesive tape half lap 3 times, 1 outsourcing of polyester shrink belt half lap in self-adhering-type silicone rubber belt 1/3 stacked package 2 times, the two glass mica powder welding region.
The limit bound edge is evenly brushed quick-drying paint in the insulating wrapping process on insulating barrier, and the complete one deck insulation of every bag is all at this surface of insulating layer brushing quick-drying paint, and electricity consumption dries up quick-drying paint behind every one deck brushing quick-drying paint.
Described groove ladder place comprises: cable joint and cable bare conductor groove and cable joint and lead wire joint overlap joint groove.Described groove ladder place filled silicon rubber insulation mud does not exceed the joint plane and seamlessly transits.
Adhesive tape is 5446-2 in the described pair of glass mica powder.
Adopt above-mentioned insulating wrapping technique, can make the welding position integral insulation function admirable of electric machine winding lead wire joint, water resistance is good, avoids occurring the insulation weak spot.
Description of drawings
Fig. 1 is process chart of the present invention;
Fig. 2 is schematic diagram of the invention process.
Embodiment
The present invention is described further below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the insulating wrapping technique of described electric machine winding lead wire joint comprises that silicon rubber insulation mud is filled, sealant is filled, insulating wrapping.
The first, silicon rubber insulation mud is filled: after finishing cable joint 1 welding, the positions such as crimp segment 3 to welding position, cable joint and cable are cleared up, and cut the groove ladder that proper amount of silicon rubber-covered mud is filled in following two places welded lap generation: cable joint 1 overlaps groove with cable 2 bare conductor grooves and cable joint 1 with the lead wire joint, require above two places filled silicon rubber insulation mud can not exceed the joint plane, should seamlessly transit simultaneously in order to avoid lap position is blocked up behind follow-up insulating wrapping.
The second, sealant is filled: after adopting silicon rubber insulation mud to fill, re-use sealant zone, cable joint 1 between lead wire joint and cable 2 insulation are filled with the former outsourcing insulating regions of lead wire joint.
Three, insulating wrapping: do not have the exposed position of insulating barrier whole with self-adhering-type silicone rubber belt 1/3 stacked package 2 times welding region.After the silicone rubber belt wrapping was finished, adhesive tape 5446-2 half lap was 3 times in the two glass mica powders of wrapping position usefulness.After the mica tape wrapping is finished, in 1 outsourcing of polyester shrink belt half lap of wrapping position.
Insulating wrapping process limit bound edge is evenly brushed quick-drying paint on insulating barrier, the complete one deck insulation of every bag all need to be at this surface of insulating layer brushing quick-drying paint.Must use hair dryer to dry up quick-drying paint behind every one deck brushing quick-drying paint.
Adopt above-mentioned insulating wrapping technique, can make the welding position integral insulation function admirable of electric machine winding lead wire joint, water resistance is good, avoids occurring the insulation weak spot.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all be included within protection scope of the present invention.
