The invention provides a method for quickly adjusting the heat flux of a platinum channel and improving power-supply efficiency, which solves the technical problems that: because of incapability of accurately calculating transformer parameters caused by a relatively high loop current in the prior art, more transformer specifications are needed; the designed direct electric heating gear is a little big; and the electric energy utilization rate is a little low. The adopted technical scheme comprises the following steps of: dividing the adaptive transformer in each zone into two types of three-specification structure designs, namely, type A and type B according to the whole design requirements of the platinum channel, outputting adaptive power of each zone by adjusting in a range of between 60 and 90 percent of full load of the transformer according to the design requirements of each zone of the platinum channel, and allowing the full load of the transformer in the range of between 60 and 90 percent to output by means of the matched specification of the adaptive transformer, the combined adjustment technological parameter change of transformation or the electrical heating load ageing. The method of the invention avoids the technical problem that the electrical parameters of platinum load cannot be precisely calculated because of the overhigh loop current, and as the output voltage can be adjusted randomly and precisely, the method solves the problem of low electric energy utilization rate.
