Problems solved by technology

[0002] Under the existing technology, for the transformer used in the skin effect electromagnetic induction cable, in order to output single-phase alternating current several times higher than the power supply frequency, multi-stage coils are generally used for voltage transformation, but the alternating current output by such multi-stage coils will be It changes with the instability of the power supply voltage, which affects the instability of the AC power equipment at the output end, resulting in safety hazards in use; the special transformer applied to the skin effect electric heating cable, when the voltage fluctuation of the grid occurs , it is easy to break down due to current imbalance, which will cause problems in the use of cables, making the heating effect of cables poor

Embodiment Construction

[0012] For ease of description, spatially relative terms such as "upper," "lower," "left," and "right" may be used herein to describe the relationship of one element or feature relative to another element or feature shown in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an orientation of above and below.

[0013] Accompanying drawing is a kind of specific embodiment of the present invention. In this embodiment, the skin-effect Scott transformer is composed of two single-phase transformers. The horizontally placed transformer is the main transformer 1, and the vertically placed transformer is the ladder...

Abstract

The invention discloses a Scott transformer with a skin effect. The Scott transformer with the skin effect consists of two single-phase transformers, the horizontally placed transformer is a main transformer, and the vertically placed transformer is a gradation transformer; a terminal A and a terminal S are arranged at the upper end and the lower end of a high voltage end of the main transformer respectively; a terminal C and a terminal B are arranged at the left end and the right end of a high voltage end of the gradation transformer respectively; the terminal S is connected with the midpointbetween the terminal B and the terminal C; the three terminals such as the terminal A, the terminal B and the terminal C are connected to a three-phase power grid U0; and an a phase and a b phase arearranged on two secondary side windings from the angle of three-phase to two-phase inversion respectively. According to the Scott transformer with the skin effect disclosed by the invention, the Scott transformer is free of circulation due to the fact that two phases on a low voltage side are free of electrical relation; and current on a high voltage side is a three-phase symmetrical system, a three-phase power supply can become into a two-phase power supply.

Description

technical field [0001] The invention relates to a transformer, in particular to a skin effect Scott transformer. Background technique [0002] Under the existing technology, for the transformer used in the skin effect electromagnetic induction cable, in order to output single-phase alternating current several times higher than the power supply frequency, multi-stage coils are generally used for voltage transformation, but the alternating current output by such multi-stage coils will be It changes with the instability of the power supply voltage, which affects the instability of the AC power equipment at the output end, resulting in safety hazards in use; the special transformer applied to the skin effect electric heating cable, when the voltage fluctuation of the grid occurs , It is easy to fail due to current imbalance, which will cause problems in the use of cables, making the heating effect of cables poor. Contents of the invention [0003] In order to make up for the ...
