关于操作高压电机的一般注意事项
如果通过驱动,高压电机可以产生电压
the load as a result of the inherent plant or system principle. The
该电压的幅度基本上取决于速度和
the type of excitation of the high-voltage motor. The following
must be noted in order to ensure that the converter power unit
safely and reliably operates while the high-voltage motor is
rotating:
•
For permanent-magnet synchronous motors, options
L49
(转换器输出处的禁用接地开关)和
L52
(转换器输出处的断路器)必须
是选择。
•
用于感应电机和单独激发同步
电机,如果电机由负载驱动,则选项
L49
和
L51 / L52
(取决于特定的申请)应该
是
选择。
Operation of Siemens high-voltage motors
A sine-wave filter is not required between the Siemens high-
电压电机H-Compact,H-Compact Plus,H-Modyn和
special motors for e.g. marine, rolling mill and high-speed
应用程序和SINAMICS GM150和SINAMICS SM150
转换器。驱动器的可靠运行确保了
以下措施:
•
The MICALASTIC VPI insulation system is optimally suited for
转换器操作中发生的电压应力。
•
从中喂养时的高压电机的保护概念
converters involves two insulating bearings to avoid damag-
ing bearing currents. Further, shaft grounding is absolutely
必要的使电动机可以在电动机上建立电压
轴相对于地面。轴是接地的
using a rotary pulse encoder with integrated grounding track
在非驱动端或使用单独的接地刷
the motor drive end. In the first case, an insulated coupling
must be used. This is because as a result of the shaft ground-
ing at the non-drive end, circulating currents can flow through
驱动的负荷。在第二种情况下,旋转脉冲编码器
必须安装在非驱动端,使其绝缘;
不需要绝缘耦合

Minimum motor rated frequency:
•
SINAMICS GM150在IGBT版本和
SINAMICS SM150 in IGBT version:
20 Hz.
•
Sinamics Gm150在IGCT版本中
SINAMICS SM150 in IGCT version:
- 8.5 Hz,输出电压为3.3 kV
-5.。0 Hz for a reduced voltage of 3.15 kV
笔记:
请联系您的区域西门子销售伙伴
不同数据的情况。
笔记
:
For motors with rated frequency of less than 8.5 Hz, a reduced
voltage of 3.15 kV should always be selected.
