一、概述
WHZD系列智能电子电动机保护器用于交流电源电压24-660V，频率50Hz或60Hz的供电电路中，与交流接交流接触器等开关组成电动机控制电路。用作于三相电动机的缺相、三相电流不平衡、过载的保护。当电动机的供电电路，二次回路出现缺相，三相电流不平衡、过载等故障时，保护器能及时切断负载的工作电源，从而可靠地保护电动机。本装置采用穿芯式电流取样电路，通过内置精密电压比较器控制，其输出端口采用无触点的固态式交流电子开关（检验开关的通断特性时不能用万用表的电阻档位进行测试）。
WHZD series smart protector applicable to an evectromotor is applicable tohe circuit with the alternating-current supply voltage 24-660V,Frequency 50Hz or 60Hz,combining the ACContactor and other switches to be an electromotor for controlling the circuit.It can be three-phrase electromotor’s lose phrase when threephrase alternating-current is unbalanceorov erlOAd protected.If the second circuit appears lose phraseor three phrase alternating-current is unbalance or overload while electromotor isworking,the protector will immediatelycut off the current supply.So it can protect the electromotor credibly.This equipment adopts the circuit withpunching cores’current,and controls the circuit with the inside nicety voltage comparator,and the output port is contactless solid AC electronic switch,(whichcan’t use multimeter resistance standard when xamineing the make-break capacity).
