摘　　要：换流站的交流滤波器投入过程当中会产生较大的涌流以及过电压现象,严重影响着相关元器件的使用寿命。不同开距下的高压断路器的关合时间以及预击穿时间存在差异。要解决交流滤波器合闸涌流及过电压,就必须研究带电投入交流滤波器的特殊工况下,残余电压、合闸相角以及合闸涌流之间的关系。文章通过分析合闸涌流产生的原理,明确影响合闸涌流及过电压的因素,探索抑制合闸涌流及过电压的具体方案。In the process of the AC filter of the converter station will produce large surge and overvoltage,which will seriously affect the service life of related components.The closing time and the pre-foundation of the high-voltage circuit device under different open distances are different by time.In order to solve the relationship between the ac filter closing surge and overvoltage must be charged into the AC filter under special working conditions,electric residual voltage,closing phase Angle and closing surge.By analyzing the principle of closing surge,the factors affecting the closing surge and overvoltage are clarified,and then the specific scheme of inhibiting the closing surge and overvoltage is explored.
