| Abstract: | A heat relay is designed on the basis of single chip PIC16F876. It firstly measures the value of three phase currents, then uses the control algorithm to imitate its characters of heat memory and antitime limit, finally realizes protection for motor when occuring over loading three phase imbalance or lose phase. The showpiece is proved to be reliable; it is good in real time performance, and easy to realize. |
