罗克韦尔AB电抗器；
Allen-Bradley reactors rated 45 Amps (fundamental) and below are supplied with an integral-
mounted terminal block.
Reactors rated from 55 to 160 Amps (fundamental) are supplied with box lugs. Reactors rated 200
to 400 Amps
(fundamental) are supplied with front facing copper tabs for cable connections. Above 400 Amps
(fundamental), side
facing copper tabs are used for cable connections. The ‘3R’ and ‘3RA’ designations for the
1321 line reactors indicate the
following: 3R = Open Enclosure Line Reactor and 3RA = NEMA 1 Enclosure Line Reactor.

1321反射波减少(RWR)装置
反射波现象的描述
驱动器的逆变部分不产生正弦电压，而是由直流产生的一系列
电压脉冲
公共汽车。这些脉冲沿着电机电缆传到马达，然后反射回驱动器。反射是
依赖于驱动输出电压、电
缆特性、电缆长度和电机阻抗的上升时间。如果
电压反射与另一个脉冲相结合，峰值电压可能处于破坏性的
水平。一个IGBT
驱动输出可能反映了两倍(2 pu或每单位)直流母线电压的波瞬态电压应力
自己的输出线。多
个驱动输出线在一个管道或金属托盘进一步增加输出线电压应力
在多驱动器输出线之间的接触。驱动# 1可能
有一个(+)2 pu的压力，同时驱动器2可以同时
有(-)2 pu应力。

Applying Allen-Bradley Line Reactors
At the Input of the Drive
At the input of a drive, line reactors help protect against surges or spikes on the
incoming power lines and help reduce harmonic distortion.
At the Output of the Drive
In long motor lead applications, Allen-Bradley load reactors located between the
drive and motor help reduce dv/dt and motor terminal peak voltages. The use of
a load reactor also helps protect the drive from surge currents caused by rapid
changes in the load.
With Multiple Drives
Multiple drives on a common power line should each have their own line
reactor. Individual line reactors provide filtering between each drive to help
reduce any crosstalk while providing optimum surge protection for each drive.
With Multiple Motors
When more than one motor is controlled by a single drive, a single line reactor
can typically be used between the drive and all the motors. Size the line reactor
based on the total motor/load horsepower.
With Single-Phase Input
A three-phase reactor can be used for single-phase applications by routing each
of the two input power conductors to the outside two coils, and leaving the
center coil disconnected. The sum of the inductance of the two coils is the total
inductance applied to the circuit. Contact Rockwell Automation Technical
Support for assistance in specifying the proper reactor.
