CURRENT REGULATING DEVICE FOR HEAVY-POWER CONVERTER SUBSTATION Russian patent published in 2005 - IPC

FIELD: electrical engineering; current regulation systems for aluminum-industry heavy-power converter substations.

SUBSTANCE: proposed device noted for high working capacity as a whole at varying input parameters and incorporating provision for multiple increase in current regulation precision has three-phase booster transformer, phase-shifting transformer, reactance components constituting three-phase resonance-tuned reactor and three single-phase capacitor units, load, three-phase autotransformer, and supply mains; in addition, at least one voltage selector switch may be introduced in device and at least one of autotransformer windings may incorporate regulation sections; moreover, at least one three-phase controlled reactor may be introduced in device and autotransformer may be provided with additional winding.

EFFECT: enlarged functional capabilities, reduced size and mass of device.
