摘　　要：采用向冲灰池直接加酸的方法，在冲灰管线正常运行的工况下，清洗冲灰管线内的灰垢，取得了满意效果，并对这种清洗工艺的技术特点进行分析讨论。The paper presents “S Injection Method”, a new principle for selection and positioning of faulty line, by which the singl phase to ground fault on the overhead line system with small current neutral grounding and CT on two phases can be detected. The paper also introduces the study on type TY 01,02, the general purposed device for single phase to ground fault line selection and positioning protection on a small current neutral grounding system based on this principle.
