Abstract

The invention relates to the high-voltage power supply field, particularly to a high-voltage electricity saving system. A high-voltage input terminal is connected in series with a three-dimensional rolling-iron-core auto transformer; an output terminal of the three-dimensional rolling-iron-core auto transformer is a multi-tap voltage regulator exciting winding provided with a plurality of gears; each gear output is connected with a switch; and each switch is connected with a control chip. With the mutual balancing effect of three phases of the three-dimensional rolling iron core in terms of magnetic potentials, voltages transmitted to electrical equipment can be balanced and stabilized, thereby achieving an objective of power saving. Meanwhile, different gears are selected and thus different voltages are outputted, so that the electrical appliance can work with a minimum proper voltage and thus the energy is saved effectively. Moreover, because of series connection of the three-dimensional rolling-iron-core auto transformer, the stability and filtering of the system are enhanced and the power factor of the system is improved.

Description

technical field [0001] The invention relates to the field of high-voltage power supply, in particular to a high-voltage power-saving system. Background technique [0002] High-voltage electricity consumption is very common in daily life. How to effectively save electricity is a matter worth considering. At present, electricity saving is generally used in the low-voltage field, and it is rarely used in the high-voltage field. Contents of the invention [0003] The technical problem to be solved by the invention is: how to effectively save high-voltage power consumption. [0004] The technical solution adopted in the present invention is: a high-voltage power-saving system, a three-dimensional wound core autotransformer connected in series at the high-voltage input end, and the output end of the three-dimensional wound iron core autotransformer is an excitation winding of a multi-tap voltage regulator. The excitation winding of the tap voltage regulator has multiple gears, ...
