逻辑控制可逆系统的安全换向与静态参数设置

Safe Conversion and Stalie Parameter Setting of Logie Controlled Convertible System

本文分析了逻辑无环流可逆系统在空载运行时逻辑控制器误动作的原因，得出了某些静态参数设置与正反两组晶闸管整流器安全换向的关系，并在某厂龙门刨床晶闸管可逆系统调试中得到了证实。

In this paper,the couse of false trip of logic conrroller in logic controlled no cirrulating current convertible system on running no-load is analysed.The relationbetween some static parameter setting and safe conversion of two thyristors is obtained,and it has been proofed in the regulalion of thyristor-fed convertible system of shappingmachine in a factory.
