负荷开关技术参数表 /Load switch technical parameter table
负荷开关为油浸式、三相联动开关、弹簧操作机构;可带负荷分合闸操作,其分合速度与操作力大小无关,型式有二工位、四工位 T 型、四工位 V 型等可供选择。
Load switch for the oil-immersed, three-phase linkage switch, spring operating mechanism; with load sub-closing operation, the combined speed and
operating force has nothing to do with the type of two-station, four-station T-type, four Type and so on.
