Abstract

The invention provides an on-load regulated capacity transformer, and particularly relates to the field of power accessories. According to the on-load regulated capacity transformer provided by an embodiment of the invention, two ends of a common capacity-adjustable circuit transformer bank are connected to second circuit transformer banks in parallel; when the capacity is required to be adjusted, the second circuit transformer banks replace a first circuit transformer bank, or the first circuit transformer bank and the second circuit transformer banks bear load together; the first circuit transformer bank can also stop working thoroughly, when the capacity of the first circuit transformer bank is adjusted, the first circuit transformer bank can be shut down, the capacity of the first circuit transformer bank can be adjusted in a powerless environment or under the condition of small load, the specification of an on-load switch is not required to be limited, and the capacity can be adjusted via any mature on-load switches.

Description

technical field [0001] The invention relates to the field of power accessories, in particular to an on-load capacity regulating transformer. Background technique [0002] Transformers use the principle of mutual inductance. The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. [0003] High-power transformers are commonly used in the field of long-distance power transmission. Usually, after the power plant generates electricity, a step-up transformer (multi-stage step-up) is used to increase the voltage of the electric energy. Amplitudes that can be used. The original transformer achieves step-up and step-down through current mutual inductance through different turns r...

AI Technical Summary

Problems solved by technology

The technical scheme of no-load capacity regulating transformer proposed in the 1980s required the power-off operation of the distribution transformer and the operation process was cumbersome, so that the no-load capacity regulating transformer basically could not play an energy-saving role in actual use.
