一、BP8Y系列频敏变阻器的用途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：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。二、BP8Y频敏变阻器型号意义三、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。四、BP8Y系列频敏变阻器外开形图及安装尺寸代号铁芯编号排数L1L2H1H2B1B21#BP8Y-104BP8Y-106BP8Y-108BP8Y-1101602301812211251511772032252512773038#BP8Y-804BP8Y-806BP8Y-808BP8Y-810BP8Y-8122303552152601221581942301663223583944304669#BP8Y-906BP8Y-908BP8Y-910BP8Y-912330510365410163209255301363409455506五、系列表根据电机规格，操作频繁程度不同，可在系列表中直接查出频敏变阻器规格。电阻器RT52-180L-6/5D电阻器RS52-250M2-8/5D电阻器RS52-250M2-8/4D电阻器RS54-280S-6/5P电阻器RS54-315M-10/8Y电阻器RY52-132M2-6/2B电阻器RT54-200L-8/1B电阻器RT52-132M2-6/1J电阻器RT52-160L-8/1J电阻器RT52-160L-6/1J电阻器RT54-160L-6/2电阻器RT54-160M1-6/1电阻器RT54-280M-8/3J电阻器RT54-225M-8/2B电阻器RS54-355M-10/9J电阻器RS54-280M-8/3J电阻器RS54-180L-8/1B电阻器RS54-225M-8/2B电阻器RZ54-280S-10/4电阻器RK52-160M2-6/1W电阻器RK52-160L-6/6电阻器RS54-225M-6/4Y电阻器JR-138-8电阻器RT54-225M-8/2Y电阻器RS54-315-6/15电阻器RS54-315S-8/9Y电阻器RT54-180L-6/3Y电阻器RS54-280M-10/5Y电阻器RT54-132M2-6/1F电阻器RQ54-280S-10/9电阻器RQ54-250M-10/9电阻器RS54-250M1-8/4J电阻器RT54-250M1-8/4D电阻器RT54-280M-8/6J电阻器RT54-180L-8/3电阻器RQ54-250M1-8/6J电阻器RT52-8/2B电阻器RT51-8/2B电阻器ZB2-27.6欧姆电阻器RS54-200L-6/4Y电阻器2P5-62-10/6Y电阻器RT42-8/2B电阻器RT54-200L-6/2D电阻器RT54-225M-8/2电阻器RQ52-200L-8/3J电阻器RS54-280S-8/5Y电阻器RT54-250M1-8/2Y电阻器RT52-132M1-6/1B(高架)电阻器RK54-200L-6/2电阻器RS54-280M-10/6电阻器RT52-112L-6/1B电阻器RT54-250M1-6/4J电阻器RT52-160L-8/2J电阻器RS54-250M-6/4电阻器RT34-225M-8/2电阻器RP54-225M-8/2电阻器RY52-180L-8/2电阻器RT52-8/2Y电阻器RT42-8/2Y电阻器RT52-160M1-6/2B电阻器RT51-8/2J电阻器RY54-225M-8/5Y电阻器RT03-4/1BC2电阻器RS54-280M-10/5电阻器RT52-160L-8/2B电阻器RT54-132M2-8/1B电阻器RT54-132M1-8/2B电阻器RT54-225M-8/1B电阻器ZK1-22-6/1B电阻器RT54-180L-8/2Y电阻器RT34-180L-8/2电阻器RT2Y2-250M1-8/2R电阻器RS54-250M2-8/5电阻器RS54-315M-8/12电阻器ZX15-75电阻器RP42-8/3电阻器RT42-8/3电阻器RT42-8/3B电阻器RT52-250M1-8/3Y电阻器RZ54-280S-8/3J电阻器RS54-315M-10/8电阻器RQ54-280S-10/8J电阻器RT54-250M1-6/4电阻器RK54-225M-8/2Y电阻器RT52-225M-6/3J电阻器RT54-200L-6/3Y电阻器RZ54-280S-10/4D电阻器RS6310/6D电阻器RT52-250M1-8/3D电阻器RQ54-225M-8/6J电阻器RS56-160L6/2B电阻器RS56-250M26/6Y电阻器RS56-250M8/5Y电阻器RS56-225M8/3Y电阻器RS56-200L8/3Y电阻器RT52-132M2-6/2B电阻器RT21-6/2B电阻器RY54-160M2-6/2B电阻器RT2Y4-160L-6/1B电阻器RT54-132M2-6/2电阻器RT52-250M-8/2J电阻器RZ54-280S-10/4Y电阻器RT54-160M1-6/3电阻器RZ54-280S-10/3电阻器RT12-6/2电阻器RQ54-250M-8/9D电阻器RQ54-280M-10/9D电阻器RT34-180L-8/2D电阻器RP56-225M-8/5电阻器RS56-355M-10/12电阻器RP56-225M-8/5J电阻器RT2Y2-112M-6/1B电阻器RP52-160L-6/2B电阻器RP52-132M2-6/1B电阻器RT41-8/2D电阻器RK54-160M2-6/2B电阻器RZ54-250M1-8/3J电阻器RT54-250M-8/3电阻器RT54-200L-8/2电阻器RT54-180L-8/2电阻器RT54-200L-8/3Y电阻器RZ54-280M-8/4电阻器RK54-220L-8/2Y电阻器RS54-250M2-8/4Y电阻器RS54-355M-10/10Y电阻器RS54-315S-8/9J电阻器RS54-280M-8/6J电阻器RS54-250M2-6/6J电阻器RT54-200L-8/2J电阻器RZ62-10/3Y电阻器RZ52-8/2Y电阻器RT54-160L-8/2B电阻器RS54-250M2-6/6电阻器RT52-180L-8/1B电阻器RT52-225M-8/2Y电阻器RZ54-315M-10/6电阻器RS54-250M2-8/4R电阻器RK54-160L-6/2Y电阻器RK62-130M1-6/1B电阻器RT54-200L-6/3D电阻器RT54-200L-6/3J电阻器RT52-180L-6/2D电阻器ZX1-2/105电阻器RQ52-160L-6/2B电阻器RZ62-10/3电阻器RZ54-225M-8/3D电阻器RS54-250M1-8/4D电阻器RT42-8/2J电阻器Z-20电阻器RS52-250M1-6/4J电阻器RS52-250M1-8/4J电阻器RS52-280S-10/5J电阻器RT52-180L-8/2J电阻器RT52-200L-6/2J电阻器RY54-180L-6/4Y电阻器RT54-250M1-8/4J电阻器RS54-180L-8/2J电阻器RQ52-200L-8/3电阻器RS54-200L-8/3B电阻器RZ62-10/4Y电阻器RK54-280S-10/4J电阻器RF54-200L-8/3B电阻器RF54-200L-6/3D电阻器RF54-160M2-6/2B电阻器RZ54-280S-10/4J电阻器RSF54-355L2-10/15E电阻器RS54-280M-8/6Y电阻器RF54-400L1-10/20Y电阻器RF54-355L1-10/13J电阻器RY54-250M1-8/4Y电阻器RT54-200L-8/3J电阻器RT2Y2-200L-8/2Y电阻器RT2Y2-132M2-6/1B电阻器RS54-280M-8/6电阻器RT52-200L-8/3J电阻器RT2Y4-160M2-6/1B电阻器RT2Y2-160M2-6/1B电阻器RT22-6/1D电阻器RZ54-225M-8/3J电阻器RZ54-250M1-8/2电阻器ZX2-2/1.6电阻器RP54-250M-8/5电阻器RT2Y4-132M2-6/1B电阻器RT52-250M1-8/3J电阻器RT42-8/2电阻器RT54-225M-8/3D电阻器RT54-200L-8/2Y电阻器RS54-250M1-8/4Y电阻器RT54-250M1-8/4电阻器RS34-315M-10-6Y电阻器RT34-200L-8/2Y电阻器ZK1-12-6/1B电阻器RT63-10/6B电阻器RS61-10/3Y电阻器RT54-225M-8/3J电阻器RT54-160L-6/2J电阻器RK54-160L-6/2B电阻器RP52-200L-8/3电阻器RK54-160M1-6/1电阻器JZR-132M2/2B电阻器ZX15-753.6欧姆(6个元件)电阻器QZX27-1电阻器QZX13-1B电阻器QZX2-2电阻器QZX2-1电阻器QZX1-5(1/2)电阻器QZX1-4电阻器QZX1-3电阻器QZX1-2电阻器QZX1-1电阻器RP52-160M2-6/1B电阻器RP54-180L-8/3D电阻器RP54-250M1-8/5D电阻器RQ54-160L-6/2B电阻器RQ54-200L-6/5电阻器RQ54-180L-6/5电阻器RZ54-160L-6/2B电阻器RZ54-250M1-8/3Y电阻器RZ54-225M1-8/3电阻器RZ54-250M2-8/B电阻器RZ54-200L-6/4电阻器RZ54-180L-6/2电阻器RZ54-160M2-6/2B电阻器RZ54-160M1-6/1B电阻器RY52-225L-8/3电阻器RY52-160L-6/3B电阻器RY52-160M2-6/2B电阻器RY52-160M1-6/2B电阻器RY52-200L-6/4电阻器RY52-180L-6/3电阻器RY52-160L-6/2B电阻器RY52-160M2-6/1B电阻器RY52-160M1-6/1B电阻器RS56-280M-8/6Y电阻器RS54-335-10/10电阻器RS54-315M-8/12P电阻器RS54-315S-10/6P电阻器RS54-250M2-6/5电阻器RS54-200L-6/4电阻器RS54-180L-6/3电阻器RS54-160L-6/2B电阻器RS54-160M2-6/2B电阻器RS54-250M1-6/4J电阻器RS52-250M-8/4J电阻器RS52-280S-8/5D电阻器RS52-225M-6/4电阻器RS52-200L-6/3电阻器RS52-180L-6/3电阻器RS52-160L-6/2B电阻器RS52-160M2-6/1B电阻器RK54-180L-8/2J电阻器RK54-250M1-8/3电阻器RK54-225M-8/2电阻器RK54-180L-8/2电阻器RK54-160L-8/1B电阻器RK54-225M-6/3电阻器RK54-200L-6/3电阻器RK54-180L-6/2电阻器RK54-160L-6/1B电阻器RK54-160M2-6/1B电阻器
