摘    要:介绍了微机备用电源自投装置的基本要求和实现条件,重点对近几年来我公司110kV及以下变电站的几起常见进线备自投现场运行中发生的主供电源永久性故障,备自投拒动;受电侧断路器偷跳,备自投拒动;受电侧断路器跳闸,检母线无压失败;一次接线方式影响备自投正确动作等典型事故进行了分析,总结分析了造成这些事故或不正常情形发生的原因,提出了对现有备自投装置的一些改进意见,并结合实践提出了在运行、检修及调试过程中应该重点注意的主要问题。经现场实践表明,上述经验和方法具备一定的参考价值。

关 键 词:微机  备自投  运行  事故  检修  调试  逻辑

Abstract:In the paper the basic requirements and achieving conditions of digital spare power automatic switch devices are introduced,focusing on the electric breaker rejecting action on the main Power permanent fault,electric breaker trips without order,electric breaker tripps while checking busbar's voltage failurly,the methods of main line influence movement exactly on digital spare power automatic switch devices. above actions for the typical faults are analyzed. the causes of the typical faults or normal circumstances are also analyzed. some improvements are introduced. the main problems during maintenance and debugging process should focus on . The field practice shows that these experience and methods have some reference values.
Keywords:microcomputer  reserve power automatic connection device  operation  accident  maintanence  debugging  logic
