Abstract
Description
図1は、実施の形態1に係る遮断装置の回路構成例を示す図である。図2は、実施の形態1における制御部の機能を実現するハードウェア構成の一例を示す図である。
(b)第1の避雷器であるユニット用避雷器41,42,43,44の制限電圧は、第2の避雷器である全点用避雷器6の制限電圧を遮断部8における各遮断ユニットの直列数で除した値の1.1倍から1.6倍までの範囲内にある。
1.1≦K≦1.6 …(2)
実施の形態1では、主遮断器21(Cb1)が先に遮断し、主遮断器22(Cb2)が遅れて遮断する場合を一例として説明した。実情的には、遅れて遮断する遮断器の方が、先に遮断する遮断器よりも遮断責務が厳しくなる場合がある。そこで、実施の形態2では、遅れて遮断する遮断器の遮断責務を緩和する実施の形態について説明する。
実施の形態1は、遮断部8を直流遮断用の遮断部として用いる実施の形態であった。実施の形態3では、遮断部8を交流遮断用の遮断部として用いる実施の形態について説明する。図13は、実施の形態1における遮断部を交流遮断用の遮断部として用いる実施の形態3に係る遮断装置の配置例を示す図である。
