Problems solved by technology

However, the current design of similar carbon brush contact auto-coupling AC voltage regulators on the market is that the wire diameters of the entire wire wrap winding from 0 to h are equal in thickness.
This will waste a lot of copper wires and increase product cost

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 2 , 3 As shown, the present invention provides a carbon brush contact type self-coupling AC voltage regulator based on segmented variable cross-section windings, including a winding 1 and a ring core 2, and the winding 1 (wire) is divided into multiple sections , the cross-sectional area of ​​each section is different; the winding 1 is wound on the annular iron core 2, and an insulating gasket 3 corresponding to each section and having a different thickness is arranged between the winding 1 and the annular iron core 2. The outer edge of the winding 1 is at the same distance from the center line of the ring core 2 .

[0022] Theoretically, the entire winding wire should use a wire with a gradually changing wire diameter, and wind it on the iron core to form a wire package. The wire diameter change is uniform an...

Abstract

The invention provides a carbon brush contact-type self-coupling-type AC (alternating current) voltage regulator based on segmented variable cross-section windings. The carbon brush contact-type self-coupling-type AC voltage regulator based on segmented variable cross-section windings comprises windings and annular iron cores; the windings are divided into a plurality of sections, and the cross-section areas of the sections are different; the windings are arranged on the annular iron cores; insulation gaskets which correspond to the sections and are different in thickness are arranged between the windings and the annular iron core; and the outer edges of the windings and the central line distances of the annular iron cores are equal. Due to adoption of the carbon brush contact-type self-coupling-type AC voltage regulator based on segmented variable cross-section windings, copper material is saved and the cost is lowered.

Description

technical field [0001] The invention belongs to the field of voltage regulators, and in particular relates to a carbon brush contact-type self-coupling AC voltage regulator based on segmented variable cross-section windings. Background technique [0002] The schematic diagram of the carbon brush contact self-coupling AC voltage regulator is as follows: figure 1 shown, enter U I Connect to both ends of 0-220V (or 0-110V), connect the output between 0-sliding contact K, and adjust the position of the carbon brush sliding contact K to adjust the output voltage. The principle of voltage regulation is: the input takes 220V as an example, when the position of the sliding contact moves to a position lower than 220V, the output voltage is lower than 220V; when the position of the sliding contact moves to a position higher than 220V, the output voltage is higher than 220V . That is, adjust the position of the sliding contact according to the need to obtain the required output vol...
