Abstract
The utility model relates to a primary and secondary coupling structure for a transformer. The coupling structure comprises an iron core of a transformer, a primary coil and a secondary coil, wherein the secondary coil is wound on the iron core, and gaps are reserved among each circle of the secondary coil; and the primary coil is uniformly wound on the gaps of the secondary coil. By adopting the primary and secondary coupling mode of the transformer, the energy loss can be greatly reduced, the power supply utilization ratio can be improved, and the defect that no-load current is increased by adopting a winding mode that the primary coil is wound on the iron core and subjected to insulation treatment, and the secondary coil is wound on the primary coil in the prior art can be overcome. The manufacture method provided by the utility model can be widely applied to a plurality of welding machines, such as WSM inverted direct current pulse argon arc welding.
Description
Technical field
The utility model relates to a kind of coupled structure, particularly relates to the alternately rich primary and secondary coupled structure of transformer on iron core of a kind of primary coil and secondary coil.
Background technology
In electric welding machine,, all be unable to do without main transformer, and main transformer is divided into primary and secondary no matter be direct current or inversion.Voltage produces magnetic field through elementary on iron core, and secondaryly through magnetic field the generation secondary voltage is arranged.Therefore, the elementary and secondary degree of coupling of transformer has determined the loss size of transformer, and it is good more to be coupled, and eddy current loss is more little, improves the utilance of electric energy so greatly.
Present transformer all is that elder generation's coiling on iron core is elementary, carries out insulation processing then, and coiling is secondary on elementary at last.
The utility model content
To the problems referred to above, the main purpose of the utility model is to provide a kind of primary coil and secondary coil the alternately rich primary and secondary coupled structure of transformer on iron core.
The utility model solves above-mentioned technical problem through following technical proposals: the primary and secondary coupled structure of a kind of transformer; Said coupled structure comprises iron core, primary coil and the secondary coil of transformer; Said secondary coil is on iron core; Leave the gap between every circle of said secondary coil, said primary coil is uniformly on the gap of secondary coil.
In the practical implementation example of the utility model, the width range in said gap is: 1-10cm.
In a practical implementation example of the utility model, the width in said gap is: 5cm.
The positive progressive effect of the utility model is: the primary and secondary coupled structure of the transformer that the utility model provides has the following advantages: adopt the transformer primary and secondary coupled modes of the utility model can reduce energy loss greatly; Improve the utilance of power supply; It is elementary to have overcome elder generation's coiling on iron core in the past; Carry out insulation processing then, the last defective that the secondary this rich system mode of coiling causes no-load current to increase easily on elementary.Such manufacture method that the utility model provides is widely used in a lot of welding machines, in WSM inversion direct current pulsed argon arc welding etc.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to specify the technical scheme of the utility model.
Fig. 1 is the structural representation of the utility model; As shown in Figure 1, the utility model comprises iron core 1, primary coil 2 and the secondary coil 3 of transformer, and secondary coil 3 is on unshakable in one's determination 1; Leave gap 4 between every circle of secondary coil 3, primary coil 2 is uniformly on the gap 4 of secondary coil 3.In the practical implementation example of the utility model, the width range in gap 4 is: 1-10cm, the width in gap 4 are preferably width and are: 5cm.In the utilization process of reality, the width in gap 4 decides according to the needs width of the primary coil 2 of coiling.
Adopt the transformer primary and secondary coupled modes of the utility model can reduce energy loss greatly; Improve the utilance of power supply; It is elementary to have overcome elder generation's coiling on iron core in the past; Carry out insulation processing then, the last defective that the secondary this rich system mode of coiling causes no-load current to increase easily on elementary.Such manufacture method that the utility model provides is widely used in a lot of welding machines, in WSM inversion direct current pulsed argon arc welding etc.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection range to be defined by appending claims and equivalent thereof.
