ABSTRACT:
A bushing temperature controller includes a transformer3which supplies a main current I1to the bushing2for accommodating molten glass, and regulation current supply units7and8which are adapted to supply regulation currents I2and I3either in phase with the main current I1or in phase inverted to the main current I1to a portion of a region to which the transformer3applies the current. Thus, the temperature control of partial regions2aand2cin the region to which the current is applied can be performed in a wide temperature range.
