Problems solved by technology

[0003] In the actual use of existing power transformers, when the voltage needs to be adjusted, it is necessary to change the gear connected to the secondary coil. During the process of changing the connection gear, the contacts are prone to sparks, and at the same time The existing power transformers have fixed adjustable gears when adjusting the voltage, and cannot steplessly adjust the voltage

Abstract

The invention relates to the technical field of transformers, and discloses a contactless stepless transformer, which comprises a magnetic silicon steel sheet iron core, a fixed winding reel, a rotarywinding reel A, a rotary winding reel B and an insulating fixing block. The left side and the right side of the magnetic silicon steel sheet iron core are vertically sleeved with the fixed winding reel and the rotary winding reel B correspondingly, the upper end and the lower end of the middle of the inner side of the magnetic silicon steel sheet iron core are fixedly provided with a fixed columnB and a fixed column A through bolts correspondingly, and the outer wall of the fixed column A and the outer wall of the fixed column B are vertically sleeved with the rotary winding reel A. In the actual use process, the number of turns of the coil C on the outer wall of the rotary winding reel B can be changed at will; and the change process of the number of turns of the coil C is smooth and stable, so that the device can realize stepless voltage transformation, the voltage can be smoothly and stably changed, and the conditions of large voltage fluctuation and high possibility of causing electric sparks in the voltage regulation process of the conventional transformer are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a non-contact stepless transformer. Background technique [0002] A power transformer is a static electrical device that is used to change an alternating voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. When the primary winding is supplied with alternating current Alternating magnetic flux is generated, and the alternating magnetic flux induces an AC electromotive force in the secondary winding through the magnetic conduction of the iron core. The level of the secondary induced electromotive force is related to the number of turns of the primary and secondary windings. That is, the voltage is proportional to the number of turns. [0003] In the actual use of existing power transformers, when the voltage needs to be adjusted, it is necessary to change the gear connected to the secondary coil. During the ...
