| 三相交流电机类负载对电源相序和电压幅值都有严格要求，通过对当今电子市场上三相电源相序鉴别产品调查后发现：大多相序鉴别产品采用集成电路实现，且只能解决缺相、鉴别相序问题。但是，当三相正相序而某一相电压出现偏高或偏低时则无法判断而导致报警失败。由于集成电路不可避免地涉及输入信号幅值范围较小和电源电压要求稳定性高等问题，通过仿真软件Altium Designer设计出了一种由模拟分立元件组成的非线性相序鉴别电路，该电路能够较好地满足缺相、正逆相序鉴别和三相正相序但某相电压偏高或偏低时能够报警动作等需求，动作时间小于0.4 s，性能可靠，可广泛应用于冶金、石油、舰船等野外电气设备挂装或便携使用，具有一定的实用价值。 |

| Three phase AC motor type of equipment has stringent requirements on the phase sequence of power and voltage amplitude. By today's electronic market survey it is found that many phase sequence identification products have the problem that they can only solve the differential phase sequence and phase loss, but in case of positive phases with one phase voltage much higher or lower, the serious result can not be judged and alarm failure would occur. For integrated circuits inevitably involve issues of small input signal and power supply voltage range, Altium Designer simulation software is used to design an analog nonlinear circuit by discrete components. The system can meet the phase missing, phase sequence identification and if a phase voltage turns high or low then alarm action will be activated in less than 0.4 s. So this circuit is reliable and can be widely used in metallurgy, petroleum, marine and other outdoor mounted or portable electrical equipment with some practical values. |
