Abstract
The present invention relates to the insulating method of magnet coil, more particularly to a kind of insulating method of super strip conductor coil.The present invention first carries out spacer insulator using interlayer of the insulation film in coil, then the coil to carrying out spacer insulator does dipping lacquer processing, takes bubble removing technique during dipping lacquer, ensures that the inside air bubble that may be present of coil excludes completely.
Description
Technical field
The present invention relates to the insulating method of magnet coil.A kind of more particularly to insulating method of super strip conductor coil.
Background technology
Magnet coil is the important component of motor and power transformer, and the quality of coil performance directly affects equipment
The heat-sinking capability and copper factor of coil greatly improved in performance, the application of super strip conductor coil（Or window utilization rate）；
The key technology of super strip conductor coil molding is to have overturned the technique that conventional coil uses insulated conductor coiling, is used
Nonisulated oxygen-free copper material is processed into after coil carries out insulation processing again, and the method for now coil insulation processing becomes coil processing
Validity key；
A kind of very simple method of the insulating method for super strip conductor coil that the present invention is announced, efficiently solves puzzlement
The technical barrier of industry.
The content of the invention
A kind of insulating method of super strip conductor coil involved in the present invention employs the lackering method of dipping lacquer；Shaping is completed
In the shape of a spiral, the number of plies is identical with the number of turn of corresponding conventional coil for super strip conductor coil afterwards, each layer of super strip conductor coil
Wire cross-section area is equal --- S1=S2 ...=Sn；
It is helical form after coil molding, it is unworkable, this hair that coil, which is carried out insulation processing to commonly use traditional technique and method,
It is bright that spacer insulator is first carried out using interlayer of the insulation film in coil, then the coil to carrying out spacer insulator does dipping lacquer processing,
Bubble removing technique is taken during dipping lacquer, ensures that the inside air bubble that may be present of coil excludes completely；
Insulation film is the film that can ensure good electrical insulating property, and this film, which has, is higher than 1010Ω cm resistivity,
Typically PET film, polyester film, Kapton, mica paper, Kapton, polyethylene film, poly- inclined difluoro second
Combination more than one or both of alkene film, polytetrafluoroethylene film；
Insulated paint used in dip-coating can be traditional secondary insulation paint immersion coating or with the addition of micro-nano thermal conductive ceramic powder
Heat conductive insulating paint.
