•性能特点
无刷无环起动器的工作原理是利用电动机在起动过程中,转子电流频率 fz 随转子转速升高而降低的关系 fz=f1×S,当转子转速由 0 上升到额定转速 Ne 时,转子电流频率则从 50Hz 平滑地降至1~3Hz。起动器阻抗 Zp=rp+jxp,其中铁损 rp的大小与频率的平方成正比,随着 fz 的降低,rp也随之下降,电抗 Xp=ωLP,同理,Xp 也减少。当起动结束后,sf1 很小,Zp 则降到很小甚至近似于零,因此电动机在起动时,既能限制起动电流,也能提高功率因数和增大起动转矩,是一种理想的起动装置。
•PERFORMANCE CHARACTERISTIC
The principle of starter is to use the current frequency of stator fz reduce when stator speed risingfz=f1xS, when the speed of stator rise 0 to rated speed ne, current frequency of stator from 50hz down to 1-3hz. of starter zp=rp+jxp, the size of iron loss rp is proportional to frequency square. with the reduction of fz, rp will go down, reactance xp=ωLp, xp will reduce. when the starting finish, sf1 is very small, zp will go down to nearly zero, so when starting, it not only limit the current, but also improve power factor and torque, which is an ideal starting equipment.
•安装与接线
与WZR无刷自控电机软起动器方式一致。
此电动机转子出头线有两种:即50KW以上的电动机转子有6个出头线(A-A、B-B、C-C),50KW以下的电动机转子只有3个出头线,本公司生产的无刷无环起动器也按功率大小,设有6个或3个接线柱。起动器装配完成后,将转子的出线接在起动器接线柱对应位置(对于有六根出线的电动机,应将同一相的两根导线,对称地接在起动器的两个接线柱上)即可,具体接线如下图所示。
•INSTALLATION AND **NNECTION
It is the same as WZR No Brush self-****olled motor soft starter.
There is 2 kind of out-head line of motor stator: 6 out-head line of more than 50KW motor stator(A-A、B-B、C-C). 3 out- head line of less than 50kw of stator. the starter also be desig** 6-3 binding post ac**rding to power. after finishing the installation, pls **nnect the line to **rresponding lo**ion of binding post.
