Description
Technical field
The utility model belongs to field of electronic devices, is specifically related to a kind of transformer framework and transformer thereof.
Background technology
Transformer is in electric equipment and radio-circuit, and transformer is commonly used for buck/boost, matched impedance, Secure isolation etc.In generator, be no matter coil movement by magnetic field or Movement in Magnetic Field by fixed coil, all can in coil induced potential, these two kinds of situations, the value of magnetic flux is all constant, but has variation with the magnetic flux quantity of coil intersecting chain, and this is the principle of mutual induction.Transformer is exactly that one utilizes undesirable mutual electromagnetic inductance to answer, voltage of transformation, the device of electric current and impedance.The most citation form of transformer, comprises the coil that two groups are wound with wire, and claims to unify in inductance mode each other.Along with the development of transformer industry, increasing enterprise enters transformer industry, also a lot of enterprise is had to show one's talent, the transformer far away that such as rings is firstly appeared and at the beginning of 21 century, is set up a specialty by joint share endeavour the research and development such as transformer, reactor, filter, manufacturer, has now become industry advanced technology leader few in number and pioneer through development in nearly ten years.Major product has: transformer series is (single-phase, three phase mains transformer, single-phase and 3-phase autotransformer, machine tool control transformer, starting compensator, energy-economic transformer, Scott Connection Transformer, three phase transformations are single-phase, single-phase change three-phase, the nonstandard transformers such as UPS transformer), (frequency converter inputs reactor series, out put reactor, DC flat-wave reactor, connection in series-parallel reactor, filter reactor, air core reactor etc.), filter series (the special input filter of frequency converter, output filter, sine wave filter) product extensively uses electric power, metallurgical, weaving, machinery, wind-powered electricity generation, the industries such as iron and steel, dark in client's favorable comment.When an alternating current (having a certain given frequency) flows in one of them group coil, the alternating voltage with same frequency will be induced in another group coil, and the voltage swing of induction depends on the degree of two coil couplings and magnetic interlinkage.The coil referring generally to connect AC power is referred to as primary winding; And be referred to as primary voltage across the voltage of this coil.May be greater than or less than primary voltage at the induced voltage of secondary coil, be determined by the turn ratio between primary winding and secondary coil.
The transformer framework being generally used for the electrical appliances such as adapter, charger, power transformer is generally divided into two kinds of structures, i.e. I-shaped structure and king's font structure.For the transformer framework of I-shaped structure, primary coil and secondary coil are successively wound in the groove of transformer framework, manufacturing process is comparatively complicated, just, general only by insulating paper separation between secondary coil, and for the transformer framework of king's font structure, just, secondary coil is wound in the two-layer up and down of transformer framework respectively, will by the shim of transformer framework, secondary coil separately, adopt insulating paper to separate compared with the transformer framework of I-shaped structure and there is better insulation effect, also be convenient to place simultaneously, secondary coil overhauls, but these two kinds of structures are due to just, secondary coil is all fixedly be wound on transformer framework, on production process, place, the winding of secondary coil need be carried out in two steps, not easily realize automation continuous productive process, simultaneously, by just, secondary coil is fixed on same transformer framework, just, when the arbitrary coil of secondary coil occurs that the reasons such as line fault need to change, can not change separately, just, secondary coil is scrapped simultaneously, add maintenance cost.
Therefore, need a kind of new technical scheme to solve the problem.
