频敏变阻器是一种有特结构的新型无触点元件。其外部结构与三相电抗器相似,即有三个铁芯柱和三个绕组组成,三个绕组接成星形,并通过滑环和电刷与绕线式电动机三相转子绕组相接。所谓频敏,就是对频率敏感。其实,频敏电阻器就是一组电感器,利用自感,对频率高的电压阻抗大,频率低的电压阻抗小。
当绕线转子式电机刚起动时,转子尚未转动,定子绕组产生的旋转磁场高速旋转,转子绕组相对高速切割磁场,产生频率高幅度也高的感生电压,转子回路的频敏电阻器呈现高阻抗,降低起动电流;转子旋转起来以后,随着转差率的降低,转子绕组切割磁场的相对速度降低,转子感生电压频率及幅度也降低;频敏电阻器呈现低阻抗;起动完成后,转差率接近于0,转子感生电压频率亦接近于0,频敏电阻器阻抗接近于0,相当于短接转子绕组(实际使用时电机启动完成后直接切除),电机正常运转。BP1-204/16003 频敏变阻器,BP1-204/12504 频敏变阻器,BP1-204/10005 频敏变阻器,
