Based on the comparison of advantages and disadvantages of several representative arc extinguishing apparatus. a new type magnetic valve arc extinguishing apparatus is introduced in this paper. The results of theoreticaI analysis and field testing show that the new type arc extinguishing apparatus can overcome the shortcomings of traditional ones and can provide a quick. accurate and optimal compensation to capacitive current in single-phase earth fault. It has important practical value and application prospect.
