摘要
FIELD: electric engineering.;SUBSTANCE: invention relates to electrical engineering and can be used in power circuits of powerful electric arc gas heaters (plasmatrons) intended for operation on direct current. Power supply source of direct-current electric arc plasmatron connected to industrial alternating current network includes rectifier and ballast load stabilizing arcing discharge current. As a ballast load there used are inductance coils installed between phases of an industrial alternating current network and a rectifier, at that the inductance coils have a number of contacts with different values of inductive resistance for selection of operating current of the plasmatron.;EFFECT: technical result is simplification of design of power supply source of electric arc plasmatron providing minimization of active electric power losses.;1 cl, 2 dwg
