摘要
阐述了消弧装置的工作原理,介绍了消弧装置的三种补偿方式及其对电网运行状态的影响。以一起因消弧装置与电网电容串联谐振导致系统电压异常的案例,给出了消弧装置串联谐振案例的分析诊断方法,分析了导致电压异常的原因,并提出改进建议,避免类似电压异常故障再次发生。
The paper expounded the working principle of arc extinguishing device. Introduction was made to three kinds of compensation modes of arc extinguishing device and their influence on running condition of power grid. Taking a case of abnormal system voltage caused by the arc extinguishing device and capacitance series resonance of power grid for example, this paper gave the analysis and diagnosis methods of arc extinguishing device series resonance case and analyzed the reason of abnormal system voltage, raising some improved suggestions to avoid the similar faults of abnormal system voltage happening again.
