If phase current is less than max-thresholds, S8 is thened follow the steps, sets minimum current threshold value, judges that phase current is less than most
Low current threshold value thens follow the steps S9, issues enabling signal.In this way, detecting one or more phase currents in three phase currents
There is the too small situation of current value, then it represents that the electric heating products occurred on the circuitry phase where the too small phase current of current value occur
Open circuit fault needs to start new spare electric heating products and puts into the circuitry phase for electric heating products failure occur.
Preferably, by being equipped with a control switch, positive reason between each spare electric heating products and terminal device
