Abstract

The invention relates to the technical field of power supplies, and discloses a single-phase precision alternating-current voltage stabilizer. The single-phase precision alternating-current voltage stabilizer aims to solve the problems that a voltage stabilizer in the prior art is unable to be adjusted precisely, and is not high in voltage-stabilization precision. The technical scheme of the single-phase precision alternating-current voltage stabilizer includes steps as below: the voltage stabilizer comprises an automatic control circuit and the like. The single-phase precision alternating-current voltage stabilizer is characterized by comprising an overlapping compensation transformer (DB), and the transformer (DB) comprises an iron core, an overlapping compensation coil (DB-1), and an overlapping excitation coil (DB-2) with more than one tap. A phase line input end (A), a compensation coil (BB-1), an overlapping compensation coil (DB-1), and a phase line output end (a) are connected in series sequentially. The overlapping excitation coil (DB-2) achieves changeable connection through being connected with a component (LY). The single-phase precision alternating-current voltage stabilizer has the advantages of improving output voltage stabilization precision greatly and the like.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a single-phase precision AC voltage stabilizer. Background technique [0002] Single-phase AC compensating voltage stabilizers in the prior art mainly include disc type and column type; in these two types of products, compensating transformers and voltage regulators are used. [0003] The compensation transformer includes a compensation coil and an excitation coil; wherein, the compensation coil is connected in series in the phase line. [0004] The input terminal of the voltage regulator is connected to the phase wire and the neutral wire; the phase wire is also commonly called the live wire, and the neutral wire is also commonly called the zero wire. The output terminal of the voltage regulator is connected to the excitation coil of the compensation transformer, that is to say: the carbon brush and other conductive contact parts slide on the copper wire or copper bar of...
