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
Electric machine winding lead wire joint carries out insulating wrapping to exposed part after welding, often there is following problem: welding position exists insulation weak spot after insulating wrapping, and integral waterproofing poor-performing, this brings certain hidden danger of quality by product.
In prior art, application number be 200710017004.0 Chinese invention patent " a kind of transformer coil lift one's head place shielding and insulating treatment method ", application number is the Chinese invention patent " insulation manufacturing method for wind driven generator " of 201110202284.9, application number is the Chinese invention patent " a kind of method for molding end nose part insulators of stator coil of generator " of 201110352379.9, application number is that the prior aries such as the Chinese invention patent " inductive coil insulating treatment of vacuum furnace " of 200610161594.X have all done certain improvement to the method relating to insulation, but there is the technical problem of insulation weak spot after all can not solving electric machine winding lead wire welding.Therefore, how to realize electric machine winding lead wire joint excellent insulating property, water resistance after insulating wrapping and well become a problem needing to solve.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of insulating wrapping technique that can realize the good electric machine winding lead wire joint of electric machine winding lead wire splice insulation function admirable, water resistance, and it can solve the technical problem that the electric machine winding lead wire joint existed in prior art exists insulation weak spot after welding.
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 completing the cleaning of lead wire weld, uses silicon rubber insulation mud to be filled in the groove ladder place of welded lap generation;
(2) sealant is filled: silicon rubber insulation mud re-uses sealant and fills the former outsourcing insulating regions of region, cable joint and lead wire joint between lead wire joint and cable insulation after filling;
(3) insulating wrapping: welding region is not had adhesive tape half lap 3 times, 1 outsourcing of polyester shrink belt half lap in exposed position entirety self-adhering-type silicone rubber belt 1/3 stacked package 2 times of insulating barrier, two glass mica powder.
Bound edge even brush quick-drying paint on the insulating layer in limit in insulating wrapping process, often wrapped one deck insulation all at this surface of insulating layer brushing quick-drying paint, after every one deck brushing quick-drying paint, electricity consumption dries up quick-drying paint.
Described groove ladder place comprises: cable joint and cable bare conductor groove and cable joint and lead wire overlapping splice groove.Described groove ladder place filled silicon rubber insulation mud does not exceed joint plane and seamlessly transits.
In described pair of glass mica powder, adhesive tape is 5446-2.
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 insulation weak spot.
Accompanying drawing explanation
Fig. 1 is process chart of the present invention;
Fig. 2 is schematic diagram of the invention process.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
As depicted in figs. 1 and 2, the insulating wrapping technique of described electric machine winding lead wire joint comprises the filling of silicon rubber insulation mud, sealant is filled, insulating wrapping.
The first, silicon rubber insulation mud is filled: after completing cable joint 1 welding, the positions such as the crimp segment 3 of welding position, cable joint and cable are cleared up, and cut proper amount of silicon rubber-covered mud and be filled in the groove ladder that following two places welded lap produce: cable joint 1 and cable 2 bare conductor groove and cable joint 1 and lead wire overlapping splice groove, require that above two place's filled silicon rubber insulation mud can not exceed joint plane, should seamlessly transit in order to avoid lap position is blocked up after follow-up insulating wrapping simultaneously.
The second, sealant is filled: after adopting silicon rubber insulation mud to fill, re-use sealant lead wire joint and cable 2 are insulated between region, cable joint 1 and the former outsourcing insulating regions of lead wire joint fill.
Three, insulating wrapping: exposed position entirety self-adhering-type silicone rubber belt 1/3 stacked package 2 times welding region not being had insulating barrier.After silicone rubber belt has been wrapped up, wrapping up position adhesive tape 5446-2 half lap in two glass mica powder 3 times.After mica tape has been wrapped up, in wrapping position polyester shrink belt half lap 1 outsourcing.
Insulating wrapping process limit bound edge is even brush quick-drying paint on the insulating layer, and often having wrapped one deck insulation all needs at this surface of insulating layer brushing quick-drying paint.Hair dryer must be used after every one deck brushing quick-drying paint to dry up 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 insulation weak spot.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, 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 amendment done, equivalent replacement, improvement etc., be all included within protection scope of the present invention.
