Title:
PHASE ANGLE ADVANCE POWER-SAVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/011257
Kind Code:
A1
Abstract:
Disclosed in the present invention is a phase angle advance power-saving device connected in series at a low voltage end of a transformer of a power system. The phase angle advance power-saving device consists of oriented silicon steel sheets and copper coils; the copper coils are connected in series in each phase, and are wound around the oriented silicon steel sheets; each phase of copper coils have two groups of independent coils; one group is forward coils-high impedance value used for generating a positive magnetic field; the other group is reverse coils-low impedance value used for generating a reversing magnetic field; the forward coils are divided into three sections (or more) by using a tapping mode; and positive magnetic fields of different intensities are generated by different impedance values of various sections. The present invention can decrease energy consumption, reduce probability of burned device and false operation, and achieve better power saving effect.
