摘要
以电磁式三极漏电断路器为例,从生产验证角度分析了零序电流互感器及执行脱扣环节的脱扣器的质量控制要点。并对零序电流互感嚣初级、次级匝数的最佳匹配进行了实例计算。
Taking electromagnetic three-pole residual circuit breaker as an example, this paper analyses quality control points of zero sequence current transformer and its tripping unit from point view of its production and gives out several example calculations on optimistic matching of primary and secondary turns of the zero sequence current transformer.
