谁知道请问fn2负荷开关安装方法

你心若移动我怎能联通 08-07 03:01

1．负荷开关的主闸*和辅助闸*(或灭弧触头)的动作顺序应该是：舍阐时，灭弧触头先闭合，主闸*后闭合；分闸时，主闸*先断开，灭孤烛头后断开。 2．负荷开关分闸后，闸*张开的距离应符合*厂的要求。如达不到要求时，可变更*作拉杆在扇形板上的位置，或改变拉杆的长度，使其符合要求． 3．调整分合闸机构时，应先慢分慢合。合闸时应使灭弧触头正好插入灭弧装置的喷嘴内，不应碰撞喷嘴，以免将喷嘴碰坏，否则应处理． 4．如安装带有熔断器的负荷开关，安装前应检查熔断器的额定电流是否与设计相符。熔断器的两端罩(端环或端帽)应封焊牢固，端帽不应活动，否则应更换。RNl型高压熔断器系用瓷管做成的，安装时应小心谨慎，不要碰坏，熔断管应紧密地插入钳口内。

负荷开关：是具有简单的灭弧装置，可以带负荷分，合电路的控制电器。能通断一定的负荷电流和过负荷电流，但不能断开短路电流，必须与高压熔断器串联使用，借助熔断器来切除短路电流。断路器：它能在负荷情况下接通和断开电路，当系统产生短路故障时，能迅速切断短路电流。它还能在保护装置的作用下自动切除短路故障。总的来说: 断路器一般用于需要经常断开的地方，负荷开关一般用于不需要经常开断的地方。希望我的回答对你有所帮助！
