DEVICE FOR CONTROLLING OR STABILISING SINGLE-PHASE OR THREE-PHASE VOLTAGE

摘要

FIELD: electricity.SUBSTANCE: invention relates to electrical engineering. The device for controlling or stabilising single-phase or three-phase voltage includes an actuating element in form of two series-connected step-down and step-up transformers, and a control unit. One part of the core of the step-down transformer and one part of the core of the step-up transformer are in form of one part of a core which is common for both cores and is configured for mechanical displacement relative the remaining fixed part of the cores, wherein the maximum cross-section of the inserted part of the core of the step-down transformer matches the minimum cross-section of the inserted part of the core of the step-up transformer, and the minimum cross-section of the inserted part of the step-down transformer matches the maximum cross-section of the inserted part of the step-up transformer.EFFECT: improved energy characteristics.2 dwg
