| Abstract: | This paper explored the contradictions caused between single switching operating device and double indendent operating circuit which were generally used in smart substation 220 V circuit, and the design of some subsidiary circuit which needs to be improved. The paper also discussed how to improve the block reclosing and fault total signal circuit, and proposed a couple of solutions. The verification was given. It will benefit reducing potential risks in the future design and construction of substation. |
