摘要

新的IEC 62271-100要求对被测断路器的容性开关能力进行广泛的证明。用于真空断路器。介质的介电性能主要取决于接触表面的状况，而接触表面的状况会受到冲击电流和负载断开电流的影响。为了详细研究这些依赖关系，并了解所研究的断流器的统计特性，建立了一个综合单相试验装置。根据预点火场强和接触冲程对结果进行了评价。应用于商业解决方案，以满足所需的标准等级C2。

Switching of capacitive currents

The new IEC 62271-100 requires an extensive proof of the capability of capacitive switching for a breaker under test. For vacuum circuit breakers. dielectric properties are mainly determined by the condition of the contact surfaces, which are modified by in-rush currents as well as load-breaking currents. A synthetic single-phase test device has been erected in order to investigate these dependencies in detail and to get knowledge of the statistical properties of the investigated interrupters. The results are evaluated with respect to pre-ignition field strengths and contact strokes. Application to commercial solutions are presented coping with the required standard class C2.
