The invention relates to a ring network switch having a nuclear phase function. According to a structure of the ring network switch, a terminal of the ring network switch is connected with a live-line display I and a live-line display II, nuclear phase terminal ports of the live-line display I and the live-line display II are respectively connected with a voltage determination monitoring module, and an output end of the voltage determination monitoring module is connected with an opening/closing lock coil of the ring network switch. The ring network switch has high reliability, detects three-phase line through sensors of the live-line displays, has properties of obvious direction, high sensitivity and safe and reliable performance; the ring network switch reduces cost, the monitoring module directly determines detection signals of the sensors, an operator has no need to make a field test, so manpower and material cost is reduced, operation is simple and convenient, safety is high; and the ring network switch
