DEVICE FOR ELECTRIC HEATING OF THE ANODES IN HIGH-VOLTAGE MERCURY-ARC RECTIFIERS

摘要

Device for electric heating of the anodes in high-voltage mercury-arc rectifiers, used in bridge converters of d.c. substations each bridge arm contains series-connected rectifiers, each having an anode reactor, an individual isolating auxiliary-power transformer and a built-in electric anode heater; the latter draws its power from the individual isolating transformer of an adjacent rectifier in the same phase, the cathode of which is at the same potential as the anode being heated, and said reactor has an additional isolated winding which connects said heaters to one of the wires of the individual isolating transformers while the other wire is one of the power buses.
