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:
第一类: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,出炉辊道,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。冶金轧钢车间桥式吊车,除主钩外,平移机构上的电机,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,每小时600—1000次,升降后,升降台辊道,压下装置,拔钢机,轧机中辊。
三、结构及安装尺寸
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,在电机启动过程中,由于等值阻抗,随转子电流频率减小而自动下降,从而只需一级变阻就可把电动机平稳的启动起来.
变阻器实质是一个铁心,损耗特大的三相电抗器.它由数片山行钢板组成,每快钢板之间有气隙垫片的铁心及线圈两个部分组成.铁心采用了冷冲制成的山字型结构.
需方给提供电机数据和频敏变阻器的启动频率,我公司可给选配合适的频敏变阻器型号。
