Electroplating or electrolysis DC supply - has separately locatable voltage regulating unit and bath current unit

摘要

Electroplating or electrolysis d.c. supply arrangements are claimed, in which a variable output alternating voltage is adjusted by a regulator (regulating transformer or thyristor regulator) forming the a.c. side and is fed to the current transformer of the d.c. side. In one arrangement, the regulator is designed and located as a separate regulating unit, the current transformer and its rectifying diodes are designed and located as a separate bath current unit, and medium voltage lines are connected between the regulating unit output and the bath current unit input for power transmission. USE/ADVANTAGE - The d.c. supplies are useful for electroplating and other electrolytic (e.g. metal electrowinning) processes. The rectifying arrangement is divided into two separate and separately locatable units (i.e. the regulating unit and the bath current unit) so that the bath current unit can be located at the electrolysis cell where it takes up less space and allows short busbars or cables to be used.
