Relay contactor control system of learning requires new thinking

Based on years of teaching experience, summed up some of the teaching methods, for your reference. Reasonable guidance, solid foundation is the first step, a good start is half the battle. Because relay contactor control system requires a new way of  mcb circuit breaker  learn: no longer concerned by the control circuit consisting of electrical voltage, current, and turned attention to the control circuit consisting of electrical, if the operation  mcb circuit breaker , the resulting control effect, so first we have to take the students have mastered the circuit theory, the use of  circuit breakers , guiding students imperceptibly transform ways of thinking, with its knowledge of the circuit has been mastered from the main building physical circuit, the basic control, so that when students do not know feel in control system design process in person perception.
