Abstract

The invention provides a tapped self-coupling AC voltage regulator based on a sectional winding with variable cross sections. The tapped self-coupling AC voltage regulator based on the sectional winding with the variable cross sections comprises the winding, the winding is a winding with a plurality of taps, and winding is divided into a plurality of sections by the plurality of taps, and the cross sectional area of every section is different. The tapped self-coupling AC voltage regulator can be a manual operated type, namely, the output end of the tapped self-coupling AC voltage regulator is connected to one tap of the winding through a voltage regulating tap switch; the tapped self-coupling AC voltage regulator can also be an electronic type, namely, the tapped self-coupling AC voltage regulator further comprises a key circuit, a main control circuit, a driving circuit and a plurality of relays; the key circuit is connected with the main control circuit, the main control circuit is connected with the driving circuit, and the driving circuit is connected with the plurality of relays; the plurality of relays are respectively connected with the plurality of taps of the winding and are used for controlling the connection and the disconnection of the taps; and the normally open contacts of the plurality of relays are connected together. By utilizing the tapped self-coupling AC voltage regulator based on the sectional winding with the variable cross sections, the copper material is saved and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of voltage regulators, and in particular relates to a tap-type self-coupling AC voltage regulator based on segmented variable-section windings. Background technique [0002] The schematic diagram of the tapped self-coupling AC voltage regulator is as follows: figure 1 shown, enter U I Connect to both ends of 0-220V, output U O Connect to one of the voltage regulator pack taps (1-8) via a voltage regulating tap changer. For example, when the tap changer is connected to tap 5, the output U O It is equal to 250V; different voltage outputs will be obtained when the tap changer is connected to different taps. However, the diameter of the entire wire wrap winding from 0 to h of the similar tapped auto-coupling AC voltage regulator design on the market is equal in thickness. This will waste a lot of copper wires and increase product costs. Contents of the invention [0003] The present invention provides a tapped se...
