Problems solved by technology

[0002] When the traditional three-phase power frequency transformer is rectified by the silicon controlled rectifier, the stable range of the output current is not wide. When the mains voltage drops to 360V, the output current begins to drop, and the output current cannot be stabilized very well.

Abstract

The invention relates to a three-phase wide-voltage power-frequency transformer structure, which includes an iron core on which a primary winding and a secondary winding are mounted, and the primary winding is composed of an upper first primary winding, an upper second primary winding, an upper third primary winding and an upper third primary winding. The lower first primary winding, the lower second primary winding, and the lower third primary winding. The upper first primary winding is located above the upper first secondary winding, the upper second primary winding is located above the upper second secondary winding, and the upper third primary winding is located above the upper third secondary winding. The lower first primary winding is located below the lower first secondary winding, the lower second primary winding is located below the lower second secondary winding, and the lower third primary winding is located below the lower third secondary winding. The structure of the three-phase wide-voltage power-frequency transformer of the present invention stabilizes the output current and is capable of stabilizing the output current in the range of three-phase 320V-440V alternating current.

Description

technical field [0001] The invention relates to a three-phase wide voltage power frequency transformer structure. Background technique [0002] When the traditional three-phase power frequency transformer is rectified by silicon controlled rectifiers, the stable range of output current is not wide. When the mains voltage drops to 360V, the output current starts to drop, and the output current cannot be stabilized well. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a three-phase wide-voltage power frequency transformer structure capable of stabilizing the output current within the range of three-phase 320V-440V AC. [0004] The technical solution adopted by the present invention to solve the technical problem is: a three-phase wide voltage power frequency transformer structure, including an iron core, a skeleton, a bracket, and a terminal post, the iron core is equi...
