 流电源转换器能线路电抗器用于电枢（DCS 50xB）和磁场DCF 50xB）电源
当晶闸管功率转换器运行时，线路换相期间电压短路
一个晶闸管连接到另一个。此操作会产生电压电源中的浸渍（公共耦合点）。对于将电源转换器系统连接至电源，
可以应用以下配置之一：关于功率转换器：表（2.6/1）中列出的线路电抗器-已分配给机组标称电流
-与变频器的电压分类无关；在某些变频器类型中，同一线路扼流圈是线路电压高达690 V-基于占空比-可用于DCS 500B和DCF 500B转换器配置A
使用功率转换器时，需要小阻抗以确保减震器的正确性能环行线路电抗器可用于满足
这个小阻抗要求。
因此，该值不得低于1%uk（相对短路电压）。
不应超过英国的10%由于相当大的电压降
然后发生。配置B如果必须满足特殊要求
PCC（标准如EN 61 800-3，
同一线路上的直流和交流驱动器等），
必须应用不同的标准选择线路电抗器。这些要求通常被定义为电压降标称电源电压的百分比。
ZLine和ZLR构成总串联阻抗安装。线路阻抗和线路电抗器阻抗决定了连接点的电压降。在这种情况下
阻抗约为4%的线路扼流圈有经常使用。配置C如果使用隔离变压器
可以符合配置B的特定连接条件，而无需使用额外的线路电抗器。这个配置A中描述的条件
届时也会感到满意，因为英国
>1%。配置C1如果两个或多个转换器应由一个提供变压器的终配置取决于
正在使用的驱动器数量及其电源容量。必须使用基于
换向扼流圈，如果驱动系统包括转换器的（C1、C2、A5、A6、，答7）。如果只有两个
A7型转换器涉及无换向扼流圈因为
这些转换器的设计适合于那条线路
Line reactorsfor armature (DCS 50xB) and field
(DCF 50xB) supplyWhen thyristor power converters operate, the line
voltage is short-circuited during commutation from
one thyristor to the next. This operation causes voltage
dips in the mains (point of common coupling). For the
connection of a power converter system to the mains,
one of the following configurations can be applied:With reference to the power converter:The line reactors listed in table (2.6/1)
- have been allocated to the units nominal current
- are independent of converter's voltage classification; at some converter types the same line choke is
used up to 690 V line voltage
- are based on a duty cycle- can be used for DCS 500B as well as for DCF 500Bconverters
Configuration AWhen using the power converter, a minimum of impedance is required to ensure proper performance of the snubber
circuit. A line reactor can be used to meet
this minimum impedance requirement.The value must therefore not drop below 1% uk (relative short circuit voltage).
It should not exceed 10% uk, due toconsiderable voltage drops which would
then occur.Configuration BIf special requirements have to be met at
the PCC (standards like EN 61 800-3,
DC and AC drives at the same line, etc),
different criteria must be applied for
selecting a line reactor. These requirements are often defined as a voltage dipin percent of the nominal supply voltage.
The combined impedance of ZLine andZLR constitute the total series impedance
of the installation. The ratio between theline impedance and the line reactor impedance determines the voltage dip at the connecting point. In such
cases line chokes with an impedance around 4% are
often used.
Configuration CIf an isolation transformer is used, it ispossible to comply with certain connecting conditions per Configuration B without using an additional line reactor. The
condition described in Configuration Awill then likewise be satisfied, since the uk
is >1 %.Configuration C1
If 2 or more converters should be supplied by one
transformer the final configuration depends on the
number of drives in use and their power capability.
Configuration A or B has to be used which are based on
commutation chokes, if the drive system consists of any
of the converters
