Description
Technical field
The present invention relates to a kind of transformer, more particularly to a kind of kelvin effect Scott transformers.
Background technology
Under prior art, for transformer used in kelvin effect electromagnetic induction cable, it is in order to export times over electricity
The single-phase alternating current of source frequency, typically using multi-pole coils carry out transformation, but this multi-pole coils its output alternating current meeting
Change with the unstable of supply voltage, so as to influence its output end alternating current using the unstable of equipment work, cause to use
On potential safety hazard；Applied to the dedicated transformer of skin-effect electric heating cable, its when voltage pulsation occurs for power network,
Easily because current imbalance breaks down, in turn result in cable and used the problem of upper so that cable heat tracing effect is poor.
The content of the invention
The present invention is in order to make up the deficiencies in the prior art, there is provided a kind of kelvin effect simple in construction, safe to use
Scott transformers.
The present invention is achieved through the following technical solutions：
A kind of kelvin effect Scott transformers, kelvin effect Scott transformers are made up of 2 single-phase transformers, horizontal positioned
Transformer is main transformer, and the transformer being disposed vertically is terraced transformer, and main transformer high-pressure side is respectively terminal A and end up and down
Sub- S, terraced step-up side or so is respectively terminal C and terminal B, and terminal S is connected with terminal B and terminal C midpoint, the A,
B and C3 terminal connect U0 three phase networks, it is described from three-phase-vice-side winding of two-phase translation-angle 2 be respectively a phases and b phases.
The distance between the kelvin effect Scott transformers, described AB, AC and BC of the present invention are equal, distance AS=/ 2*AB.
The kelvin effect Scott transformers of the present invention, the iron core of the kelvin effect Scott transformers is single or twin-core
Structure.
The beneficial effects of the invention are as follows：
The kelvin effect Scott transformers of the present invention, due to contact of the low-pressure side two-phase without electricity, therefore aspergillus ficuum；High-pressure side electricity
Stream is three-phase symmetrical system, can be changed into two-phase power supply with three phase mains.
Brief description of the drawings
The invention will be further described below in conjunction with the accompanying drawings.

Device is squeezed, be stated as positioned at other elements or feature " under " element will be located into other elements or feature " on ".Cause
This, exemplary term " under " both upper and lower orientation can be included.
Accompanying drawing is a kind of specific embodiment of the invention.The embodiment kelvin effect Scott transformers, kelvin effect
Scott transformers are made up of 2 single-phase transformers, and horizontal positioned transformer is main transformer 1, and the transformer being disposed vertically is
Terraced transformer 2, the high-pressure side of main transformer 1 are respectively that terminal A and terminal S, the terraced high-pressure side of transformer 2 or so is respectively terminal up and down
C and terminal B, terminal S are connected with terminal B and terminal C midpoint, described from the three-phase-vice-side winding of two-phase translation-angle 2 difference
For a phases and b phases, A, B, C3 terminals connect U0 three phase networks, and ABC is equilateral triangle, center line AS distances be equal to the length of side/2, in
Property point x be connected and take notice of with y, primary side Ia=Ib=Ic three-phase currents are balances when Ua=Ub in operation, Ia=Ib；First winding BC
Rated voltage be U0, AS rated voltage is U0*/2.
The specific implementation to the present invention is described in detail above, but is intended only as an example, and the present invention is not
Specific implementation case described above is limited to, the equivalent modifications carried out to the present invention are also within protection scope of the present invention.
