Abstract
The utility model discloses a primary-secondary independent switching transformer comprising a primary side bobbin which a primary coil is independently wound on and a secondary side bobbin which a secondary coil is independently wound on. The primary side bobbin and the secondary side bobbin are fixed together through a magnetic core. The bobbins include the primary side bobbin and the secondary side bobbin, the primary side bobbin is used for full-automatic high-speed winding of coils, and winding speed is increased and winding uniformity can be guaranteed; the coil can be wound on the secondary bobbin with no need for coating with nonwoven or adhesive tapes, coil windings can be insulated just by using cotton-covered wires, and inter-turn badness is prevented accordingly; the EE type magnetic core is less prone to deformation, cracking or the like than the EFD type magnetic core, and yield of products is increased accordingly.
Description
Technical field
The utility model relates to a kind of primary and secondary self switch transformer, belongs to field transformer.
Background technology
EE type transformer framework draws the monolithic devices skeletons that adopt more at present, high-power transformer also will ensure the safety distance of primary and secondary and magnetic core simultaneously, need to add shell protects, and for ensureing safety requirement, product generally all needs to wrap nonwoven adhesive tape, between winding, wrap insulating tape, efficiency is low little, and consistency is poor.
Utility model content
Utility model object: the utility model proposes a kind of primary and secondary self switch transformer, saved the operation of bag nonwoven adhesive tape or layer insulation adhesive tape.
Technical scheme: the technical solution adopted in the utility model is a kind of primary and secondary self switch transformer, comprise the primary side skeleton of coiling primary coil respectively, and the primary side skeleton of coiling secondary coil, magnetic core is fixed together primary side skeleton and primary side skeleton.
Preferably, described magnetic core is made up of two " E " sections magnets.
Preferably, described primary side skeleton is provided with the first wing plate.Described primary side skeleton is also provided with the second wing plate.
Beneficial effect: skeleton is divided into primary side skeleton and primary side skeleton by the utility model, primary side skeleton can wind the line with high-speed full-automatic, raising speed and can ensure coiling consistency; The coiling of primary side skeleton does not need to wrap nonwoven, encapsulate band, only adopts cotton covered wire just can ensure the insulation between coil windings, thereby prevents that turn-to-turn is bad; EE type magnetic core is not easy distortion, cracking etc. compared with EFD type magnetic core, thereby improves the qualification rate of product.
