4). 直流电抗器
功率为的驱动器需要直流电抗器
大于EV2000-4T0750G，适用于其
功率低于EV2000-4T0750P，可选。
在下列条件下，应使用直流电抗器
减少交流电源对驱动器的影响，并
保护驱动器并抑制高阶
谐波。
（1） 如果电容器箱用于无功功率
补偿或SCR负载共享相同的AC
与驱动器一起供电，SCR引起的谐波
接通或断开时的负载或电容器箱
可能损坏驱动器的输入整流电路；
（2） 当三相交流电源的不平衡率
驱动力大于3%；
（3） 如果要求驱动器的输入功率因数为：
大于0.93；
（4） 当大容量变压器连接到
驱动器的输入电流可能会损坏
整流电路。通常，如果输入交流电源
驱动器的容量大于550KVA，或者如果输入AC
电源容量是驱动器的10倍，直流
反应器需要连接到驱动器。
（5） 输入交流线路电抗器
如果功率失真，应使用线性电抗器

驱动因素。
6） 输出交流线路电抗器
当从驱动器到电机的电缆长于
80m多股电缆和交流线路电抗器

（9） 安全地面
由于驱动器内部存在泄漏电流，因此
安全，驱动器和电机都应接地，
接地电阻应小于10Ω. 这个
地线应尽可能短。请参阅

0300P1 are respectively the RT16 Series 63A and 80A
products of Xi'an Fusegear Manufacture Company.
4). DC reactor
DC reactor is required for the drive whose power is
greater than EV2000-4T0750G, for the drive whose
power is lower than EV2000-4T0750P, it is optional.
Under following conditions, a DC reactor should be used
to reduce the impact of AC supply to the drive and to
protect the drive and suppress the high-order
harmonics.
(1) If a capacitor tank used for reactive power
compensation or a SCR load shares the same AC
supply with the drive, the harmonics caused by the SCR
load or the capacitor tank when it is switched on or off
may damage the drive’s input rectifying circuit;
(2) When the unbalance rate of 3-phase AC supply of
the drive is greater than 3%;
(3) If the input power factor of the drive is required to be
greater than 0.93;
(4) When a large capacity transformer is connected to
the drive, the input current of the drive may damage the
rectifying circuit. Generally, if the input AC supply
capacity of the drive is above 550KVA, or if the input AC
supply capacity is 10 times that of the drive, a DC
reactor is required to connect to the drive.
(5) Input AC Line Reactor
A line reactor should be used if the distortion of power
network is severe or the input current harmonic level is
high even after a DC reactor has been connected to the
drive. It can also be used to improve the AC input power
factor of the drive.
6) Output AC Line Reactor
When the cables from the drive to motor are longer than
80m, multi-stranded cables and an AC line reactor
should be used to suppress the high frequency
harmonics. Thus, the motor insulation is protected
against heat due to harmonics, leakage current is
reduced and the drive will not trip frequently.
(7) Input EMI filter
An EMI filter can be used to suppress the high
frequency noise generated by the drive’s power cables.
(8) Output EMI filter
An EMI filter can be used to suppress the drive’s output
noise and leakage current of cables.
(9) Safety ground
Since there is leakage current inside the drive, to ensue
safety, both the drive and the motor should be grounded,
the grounding resistance should be less than 10Ω. The
ground wire should be as short as possible. Please refer
to the section of the earth wire in Tab
