5.5.10在运行位置上的隔离插头能耐受短路冲击电流,并保证接触良好,隔离插头符合SD201规定。

5.6联锁装置
5.6.1断路器手车只有在断开/试验位置或工作位置时,合上推进机构提手,断路器才能进行合分操作,而且在断路器合闸后,手车的推进机构无法操作,防止带
负荷推拉断路器手车;
5.6.2只有当断路器退至断开/试验位置,手车才能从柜体拉出;
5.6.3仅当接地开关处在分闸时,断路器手车才能从断开/试验位置运动至工作位置,仅当断路器手车处于断开/试验位置时,接地开关才能合闸操作,这样实现了防止带电误合接地开关处于闭合状态时关合断路器。

5.6.4接地开关处于分闸状态时,电缆室门无法打开,防止了误入带电间隔;而电缆门打开后,接地开关不能分闸。

5.6.5断路器手车处于试验或工作位置而没有控制电压时,仅能手动分闸而不能合闸;
5.6.6断路器手车在工作位置时,二次插头被锁定不能拔除。
