Description
Technical field
The utility model relates to a kind of transformer, relates in particular to the good high pressure diecasting formula transformer of a kind of casing thermal diffusivity.
Background technology
Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, main member is primary coil, secondary coil and magnetic core, in electric equipment and radio-circuit, be commonly used for effects such as lifting voltage, matched impedance, safety isolation, the transformer the inside is a coil, flow through as electric current, will produce magnetic field, copper loss and iron loss are just arranged.Copper loss is meant the caused loss of transformer coil resistance.When electric current passes through coil resistance adstante febre, the loss with regard to changing heat energy into of a part of electric energy.Because coil generally all is entwined by the copper cash of tape insulation, therefore be called copper loss.
The iron loss of transformer comprises two aspects.The one, magnetic hysteresis loss, when alternating current when the transformer, its direction of the magnetic line of force and size by transformer silicon steel sheet change thereupon, make the mutual friction of silicon steel sheet interior molecules phase, emit heat energy, thus loss a part of electric energy, this is a magnetic hysteresis loss.Another is an eddy current loss, when transformer is worked, has the magnetic line of force to pass in the iron core, will produce induced current on the plane vertical with the magnetic line of force, forms circulation because this electric current has the closed-loop path of one's own, and becomes swirl shape, so be called eddy current.The existence of eddy current makes iron core heating, consumed energy.
Copper loss and iron loss have consumed extra electric energy in daily use, cause secondary side voltage not reach expection voltage, and the coil heat production causes current carrying capacity of conductor to reduce, and if things go on like this, will influence transformer's life span.
Summary of the invention
At above-mentioned defective, the utility model discloses a kind of high pressure diecasting formula transformer, it can effectively reduce copper loss and iron loss, thereby has solved the problem that the overheated transformer life that causes of coil shortens.
The utility model discloses a kind of high pressure diecasting formula transformer, it comprises coil unit, regulator and outlet terminal, it is characterized in that: described coil unit comprises iron core, high-tension coil, low-voltage coil and lead-in wire; Described outlet terminal is HV Terminal and low-voltage terminal.
The utility model also comprises a cooling device, and described cooling device is arranged on the transformer bottom.
The utility model high-tension coil comprises copper conductor, F grade resins layer, semiconductor layer, glass fiber mesh, external insulation protective layer.
Copper conductor described in the utility model uses the copper conductor of high-quality high conductivity, makes the coil inside Potential distribution even, and potential difference is little and form low partly discharge, improves the ability that coil life-span and withstand voltage are impacted.The resin of the F level that resin bed employing proof voltage height and tension stress are strong, and add SiO
2, improve resin heat conductivity and anti-flammability.Use glass fiber mesh to strengthen at the most inside and outside layer of coil, both guaranteed resin thickness, more coil tolerance short-circuit capacity is improved.
