微机备用电源自投装置现场运行分析

Analysis of microcomputer emergency power supply turns oneself in intall

介绍了微机备用电源自投装置的基本要求和实现条件,重点对近几年来某供电公司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。

Introduced the microcomputer emergency power supply turns oneself in the installment basic request and the realization condition, key prepares to in the last few years our company 110 kV and following transformer substation several common coils in turns oneself in the supply power source permanent breakdown which in the scene movement occurs, prepares turns oneself in resists to move; Is stolen the electricity side circuit breaker jumps, prepares turns oneself in resists to move; The electricity side circuit breaker trip, is examined the generatrix not to press the defeat; A wiring way influence prepared turns oneself in the correct movement and so on the typical accident to carry on the analysis, summarized analyzes has created the reason which these accidents or not the normal situation occurred, proposed to existing prepared turns oneself in the installment some improvement opinion, and unified the practice to propose in the movement, the overhaul and the debugging process should the key attention main question. Indicated after the scene practice that, above experience and the method have certain reference value.
