摘　　要：高压熔断器是用于6～10kV输电线路和变压器的短路保护。重点分析了RW4-10/200型户外跌落式熔断器在性能上不够稳定,且无法避免三相不平衡和非全相运行,易发生湿闪、过热等现象。详细讨论了用压气式负荷开关来代替RW4-10/200型户外跌落式熔断器的可行性。The pa pe r mainly analyses the non-stability performance,discharge caused by mois-ture ,super-heat,and the cause of electric-network three-phase unbalance as well as the non-three-phase operation when the RW4-10/200lapse fuse is in operation.Furthermore,it discusses in details about the feasibility of adopti ng the compressed-air load switch to replace the RW4-10/200outdoor-lap se fuse.

关 键 词：运行 高压跌落式熔断器 压气式负荷开关 熔断
