摘要
分析了主流的调匝式和可控硅调谐式自动跟踪类型消弧线圈测量系统电容电流的原理,结合同一配电网两台自动跟踪消弧线圈运行时电网等效电路模型的理论推导,提出了在不同情况下装置测量电网对地容抗的修正计算公式,在两台自动调谐消弧线圈运行于同一配电网情况下,推荐两台消弧线圈的选型方案.
The paper analyzes the measurement fundamental of two types of arc suppression coils, combining principal understanding in electrocircuit model of operation in the same power system. Then, the advanced formula for measuring the grounding current of these two types of arc eliminating coils in different condition is suggested, and the precepts are provided to be chosen when two arc suppression coils operate in the same power system.
