摘要
本文介绍三相交流电相序的逻辑判别方法及实用电路。它较传统的模拟判别方法逻辑分明、判断准确、功耗甚微,并可以直接驱动相序执行机构。它不仅可判别相序,而且可以实现相序锁定、恒相序输出等有关相序控制。
This pape presents logical decision method of three AC phase sequence and practical circuit It is clear logical correct judgement and very low in power dissipation compared with the conventional analogy method and can directly drive executive mechanism of phase sequence.It not only distinguishes phase sequence but also achieves phase sequence lock constant phase sequeuce output and with relation to phase sequeace control. Therefore it has a certain practical meaning in production ,practice
