BP8Y频敏变阻器
一、用途
BP8Y频敏变阻器实质上是一种无触点电磁元件,相当于一个等值阻抗,在电动机起动过程中,由于等值阻抗,随转子电流频率减小而自动下降,从而只需一级变阻器就可把电动机平稳的起动起来。
BP8Y频敏变阻器的工作条件:
依据操作的频繁程度不同,可分为三类:
**类:稍频繁,每小时100-400次,机械车间的桥式吊车上除主钩外,平移机钩上的电机,出米辊道,拉钢机等,大多数刚起动就断电。
第二类:较频繁,每小时400-600次。冶金轧钢四间桥式吊车,除主钩外,平移机钩上的电机,轧机前后工作辊道,延伸辊道等,大多数刚起动就断电。
第三类:频繁操作,第小时600-1000次,升降后,升降台辊道,压下装置,拔钢机,轧机中辊。

三、BP8Y频敏变阻器结构及安装尺寸
BP8Y频敏变阻器实质是一个铁芯,损耗特大的三相电抗器。它由数片山形钢板叠合而成,每块钢板之间有气隙垫片的铁芯及线圈两个主要部分组成。铁芯采用冷冲制成的山字型结构。
结构及安装尺寸见上图。
