150-F317NBD150-F317NBD150-F317NBD软启动器(软启动器)是一种集电机软起动、软停车、轻载节能和多种保护功能于一体的新颖电机控制装置,国外称为SoftStarter。软启动器采用三相反并联晶闸管作为调压器,将其接入电源和电动机定子之间。这种电路如三相全控桥式整流电路。使用软启动器启动电动机时,晶闸管的输出电压逐渐增加,电动机逐渐加速,直到晶闸管全导通,电动机工作在额定电压的机械特性上,实现平滑启动,降低启动电流,避免启动过流跳闸。待电机达到额定转数时,启动过程结束,软启动器自动用旁路接触器取代已完成任务的晶闸管,为电动机正常运转提供额定电压,以降低晶闸管的热损耗,延长软启动器的使用寿命,提高其工作效率,又使电网避免了谐波污染。软启动器同时还提供软停车功能,软停车与软启动过程相反,电压逐渐降低,转数逐渐下降到零,避免自由停车引起的转矩冲击。41391-454-01-B1FX41391-454-01-D1BX41391-454-01-D1CX41391-454-01-D1DX41391-454-01-S1FX41391-454-02-D2BX41391-454-02-S2FX41391-454-05-S1FZ41391-801-0141391-801-0241391-801-0341391-801-0541391-803-02150-F108NBD150-F108NBDB150-F108NBDD150-F108NBR150-F108NZD150-F1250NBA150-F1250NBE150-F1250NBEB150-F1250NZA150-F135FBD150-F135NBD150-F135NBDB150-F135NBDD150-F135NBR150-F135NBRD150-F135NZD150-F135NZDB150-F201FBD150-F201NBD150-F201NBDB150-F201NBDD150-F201NBR150-F201NBRB150-F201NBRD150-F201NCD150-F201NCDB150-F201NZD150-F251FAD150-F251FBD150-F251NBD150-F251NBDB150-F251NBDD150-F251NBR150-F251NCD150-F251NCDB150-F251NZD150-F25NBD150-F25NBDB150-F25NBR150-F317FBD150-F317FBD-20E-NB-UL)
