摘要
针对WKBC I型四合一微机控制台在运行过程中发生拒动的现象,从跳闸控制电路原理上进行了深入的剖析,找到了故障原因所在,提出了一套可行的解决方案。从根本上解决了原控制电路设计所存在的问题,提高了装置的可靠性,并对原装置在现场运行过程中出现的异常情况进行了合理解释。
A feasible scheme to WKBC I four in one microcomputer control table of miss trip is presented and deeply analysed in this paper from the aspect of the principle of control circuit. The schemes not only solve the problem in maloperation but also improve the reliability of the device and give logical explaination to some unconventionality phenomena in real work.
