[0023] Example: see figure 1 .
[0024] An energy-saving control system for a heating device, which includes: a sampling module, a switching device, and a control system, wherein the sampling module is used to collect voltage signals and current signals output by three-phase electricity; the switching device is used to switch the external output of three-phase electricity The control system receives the voltage and current signals collected by the sampling module, and controls the switching device to work according to the voltage and current signals, so that the load of the output three-phase electricity is balanced.
[0025] In this technical solution, the voltage and current signals input to the load are collected through the sampling module, and the sampling module can use a transformer; when the load of the three-phase electricity is unbalanced, there are differences in the current and voltage of the three-phase electricity. At this time, through The switching device redi...
