摘　　要：串补平台存在较多的电容元件,且其面积较大,相对于500k V母线,串补对地电容较大,在非等电位拉合刀闸时,产生的电弧强度远比普通500k V非等电位拉合刀闸产生的电弧大。在实际运行中也出现过多次保护退出,保护误动等现象。本论文通过对分合刀闸进行分类,区分等电位与非等电位拉合刀闸的区别。并对实际干扰情况进行分析,对增加高频滤波电容的作用进行分析。针对现有端子箱的技术标准,与特殊情况下屏蔽需求,提出修改端子箱标准的意见。针对现有装置接地方式进行分析,并提出改进意见。对现二次电缆的屏蔽方式进行分析,提出改造意见。为串补平台的抗干扰提出建设性意见。There are many series compensation capacitor element on the platform, and the platform is larger than the 500kV bus. The capacitance to ground is larger too. In the equipotential close breaker, the arc intensity than the ordinary 500kV of equipotential pull us and produce big arc breaker. In actual operation, there have been many times to protect exit, protection malfunction and so on. This paper through to the breaker points or the classify, distinguish with the equipotential bonding breaker close the difference. And analyze the actual interference, proposed in view of the terminal box of shielding requirements, device grounding method and other improvements, for series compensation platform of anti-jamming solution is put forward.
