Abstract
The utility model discloses a dry type transformer with an insulating wrapping wire, comprising an insulating wire which comprises a wire inner layer and an insulating wire outer layer. The wire inner layer is a polyester film layer. With adoption of the scheme, the insulating strength is increased, local discharge is decreased and the wrapped insulation is reduced in weight. The volume is reduced so that the cost of the transformer and electrical energy loss are reduced with better technical effects.
Description
Technical field
The utility model relates to a kind of transformer, relates in particular to the dry-type transformer of a kind of material savings, easy recovery.
Background technology
Transformer is the device that a kind of principle of utilizing electromagnetic induction changes alternating voltage, and its main member is primary coil, secondary coil and iron core (magnetic core).In electric equipment and radio-circuit, up-down voltage, the matched impedance done commonly used, safety isolation etc.
The function of transformer mainly contains: voltage transformation; Current transformation, impedance conversion; Isolate; Voltage stabilizing (magnetic saturation transformer); Autotransformer; High-tension transformers (dry type and oil immersed type) etc., the core configuration that transformer is commonly used generally has E type and C sections core, XED type, ED type CD type.
Most transformer all has fixing iron core, is wound with once the coil with secondary on it.Based on the high magnetic conductivity of iron material, most of magnetic flux is confined in the iron core, and therefore, two groups of coils can obtain the magnetic coupling of suitable high level by this.In some transformers, the two closely combines coil and iron core, and once almost the coil ratio with the two is identical with the ratio of secondary voltage for it.Therefore, the turn ratio of transformer can be used as generally that transformer boosts or the reference index of step-down.The function with step-down because this boosts; Make transformer become the important adjunct of one of modern power industry system, promote transmission voltage make long-distance transmit electric power more economical, as for step-down transformer; It makes the diversification more of power operation aspect; Can say so, not have transformer, modern industry can't reach the present situation of present development in fact.
But present a lot of transformers often do not reach client's particular requirement when in use, and this has brought certain challenge part also for the research and development and the design of transformer.
Summary of the invention
The utility model provides a kind of transformer of new structure to the shortcoming of existing transformer, and said transformer has insulating bag and pricks lead, and then reduces the cost of transformer and the loss of electric energy.
The utility model solves the problems of the technologies described above technical scheme such as the following description of being adopted:
A kind of dry-type transformer that has insulation wrapping lead comprises, insulated conductor, said insulated conductor comprise insulated conductor internal layer and insulated conductor skin, and wherein, said insulated conductor internal layer is by laminated polyester film.
Further, preferred construction is that said insulated conductor skin is the glass fiber layer.
The utility model can make the dielectric strength increase after having taked such scheme, partial discharge reduces, and the insulation weight of wrapping reduces, and the volume minimizing reaches the cost of reduction transformer and the reduction of electric energy loss, has better technical effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is carried out detailed description, so that the above-mentioned advantage of the utility model is clearer and more definite.
Fig. 1 is the sketch map of the transformer coil of the utility model dry-type transformer;
Fig. 2 is the conductor cross-section figure of the transformer coil of the utility model dry-type transformer.
Embodiment
Come the utility model is described below in conjunction with accompanying drawing and specific embodiment.
Fig. 1 is the sketch map of the transformer coil of the utility model dry-type transformer.
Fig. 2 is the conductor cross-section figure of the transformer coil of the utility model dry-type transformer.
As depicted in figs. 1 and 2, said transformer comprises transformer high-voltage coil, and said transformer coil comprises insulated conductor 1.
Wherein, said insulated conductor comprises insulated conductor internal layer 2 and insulated conductor skin 3, and; Said insulated conductor internal layer 2 is laminated polyester films of being processed by the polyester film material; The thickness of this laminated polyester film is 0.11 millimeter, and wherein, lead 1 is arranged between two insulating barriers.
Wherein, said insulated conductor outer 3 is glass fiber layers of being processed by the glass fiber material, and the thickness of this glass fiber layer is 0.26 millimeter.
The utility model can make the dielectric strength increase after having taked such scheme, partial discharge reduces, and the insulation weight of wrapping reduces, and the volume minimizing reaches the cost of reduction transformer and the reduction of electric energy loss, has better technical effect.
It should be noted that; Above-mentioned specific embodiment only is exemplary; Under the above-mentioned instruction of the utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improve or distortion drops in the protection range of the utility model.
It will be understood by those skilled in the art that top specific descriptions just in order to explain the purpose of the utility model, are not to be used to limit the utility model.The protection range of the utility model is limited claim and equivalent thereof.
