FMR231-AAGNJEA2AA经济实用，特价处理，批发库存，X爆料！
隔离开关功能：FMR231-AAGNJEA2AA
1.用于隔离电源，将高压检修设备与带电设备断开，使其间有一明显可看见的断开点。
2.隔离开关与断路器配合，按系统运行方式的需要进行倒闸操作，以改变系统运行接线方式。
3.用以接通或断开小电流电路。
隔离开关主要作用：FMR231-AAGNJEA2AA
1)分闸后，建立可靠的绝缘间隙，将需要检修的设备或线路与电源用一个明显断开点隔开，以保证检修人员和设备的安全。
2)根据运行需要，换接线路。
3)可用来分、合线路中的小电流，如套管、母线、连接头、短电缆的充电电流，开关均压电容的电容电流，双母线换接时的环流以及电压互感器的励磁电流等。
4)根据不同结构类型的具体情况，可用来分、合一定容量变压器的空载励磁电流。
隔离开关特点：FMR231-AAGNJEA2AA
1.在电气设备检修时，提供一个电气间隔，并且是一个明显可见的断开点，用以保障维护人员的人身安全。
2.隔离开关不能带负荷操作：不能带额定负荷或大负荷操作，不能分、合负荷电流和短路电流，但是有灭弧室的可以带小负荷及空载线路操作。
3.一般送电操作时：先合隔离开关，后合断路器或负荷类开关；断电操作时：先断开断路器或负荷类开关，后断开隔离开关。
4.选用时和其它的电气设备相同，其额定电压、额定电流、动稳定电流、热稳定电流等都必须符合使用场合的需要。
