Description
Technical field
The present invention relates to a kind of transformer, particularly relate to the heterogeneous self coupling phase-shifting rectifier transformer of using in a kind of high voltage frequency conversion system.
Background technology
Growing along with energy resource consumption, power-saving technology is more and more subject to the attention of various countries, and increasing high voltage converter is widely used; High voltage converter can be realized the stepless time adjustment of high-voltage motor, to improve industrial products quality and energy savings, reduce costs and have great significance.
Because the secondary side winding of polyphase windings phase shifting transformer exists phase difference each other, realize input multiplex, can eliminate thus the pollution to electrical network of harmonic wave that the each unit of frequency converter produces, be the important component part that high voltage converter becomes " green " power electronic product.
In high voltage converter rectification circuit in order to obtain good output voltage wave, generally need to adopt the rectifier system of multiple input, need two even more rectification modules above in parallel, as shown in Figure 1, rectification module 1 is connected with transformer A and B respectively with 2, at the right side of rectification module output loading required voltage.
If the output impedance of transformer A, B is inconsistent, in the time of rectification module 1 and 2 work, between module 1 and 2, will produce electrical potential difference, cause having current flowing to form circulation between module 1 and 2, increase rectifying device overheated risk of burning occurs; In order to make not produce circulation between rectification module 1 and 2, the problem that needs solution is that the secondary side output impedance of requirement transformer A and B is completely equal.
The solution generally adopting is at present to carry out primary side phase shift at transformer A and B, and secondary side only need to be placed output winding, does not need to place phase shift winding again; The secondary side of such two transformers just can be made same winding mode to meet two requirements that Circuit Fault on Secondary Transformer output impedance is equal.The weak point of above solution is the transformer that needs two platform independent, takies valuable installing space, and manufacturing cost can corresponding increase.
Summary of the invention
The object of this invention is to provide a kind of heterogeneous self coupling phase-shifting rectifier transformer, its volume is little, simple in structure, and the impedance of secondary outlet side equates.
For solving the problems of the technologies described above, heterogeneous self coupling phase-shifting rectifier transformer of the present invention, comprise first side winding and secondary side output winding, described first side winding and secondary side output winding form self coupling loop, and, in described first side winding, be connected with phase shift winding, the coil of described secondary side output winding be in the same way and around.
Further, the number of phases of described heterogeneous self coupling phase-shifting rectifier transformer is 3 phases.
Adopt technique scheme, beneficial effect of the present invention is: heterogeneous self coupling phase-shifting rectifier transformer small volume of the present invention, and simple in structure, and the impedance of secondary outlet side equates.

Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figures 2 and 3, the present embodiment is a kind of heterogeneous self coupling phase-shifting rectifier transformer, and it is a three-phase transformer, and three-phase is respectively A phase, B phase and C phase.Every first side winding and secondary side output winding that includes mutually, described first side winding forms self coupling loop with secondary side output winding, is connected with phase shift winding in described first side winding, the coil that described secondary side is exported winding be in the same way and around.
Secondary side output winding is used and the mode of the division of having mercy on combines two transformers in prior art, because second siding ring be in the same way and around, so two groups of secondary side ports of transformer (port one, 2,3 and port 4,5,6) output impedance is completely equal.Can at utmost reduce the asymmetry of secondary side output impedance, thereby improve the stability of commutation system.Because secondary side output winding has been split into two groups of ports, so the half that the power output of every group of port is gross power.
In use, first side winding connects 3 phase AC voltages to this heterogeneous self coupling phase-shifting rectifier transformer, and the port one, 2,3 of secondary side is connected with rectification module 1, and port 4,5,6 is connected with rectification module 2.Two rectification modules are load supplying jointly.
The above embodiment has only expressed embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
