drawation数据
Sinamics G120p机柜units and the associated system
components are rated for an ambient temperature of 40 °C
(104°F)和安装高度最多1000 m(3281 ft)
海平面。
在> 40°C(104°F)的环境温度下,输出电流
must be reduced. Ambient temperatures above 50 °C (122 °F)
不允许。
At installation altitudes > 1000 m (3281 ft) above sea level, it
must be taken into account that the air pressure, and therefore
air density, decreases as the height increases. As a conse-
征服,冷却效率和绝缘能力
air also decrease.
Due to the reduced cooling efficiency, it is necessary, on the one
hand, to reduce the ambient temperature, and on the other
手,通过减少转换器机柜单元的热量损失
the output current.
As additional measure for installation altitudes from 2000 m
(6562 ft)最多4000 m(13123 ft),隔离变压器为
required in order to reduce transient overvoltages according to
EN 60664-1。
Automatic adjustment of pulse frequency for converter cabinet
框架尺寸GX的单元开始
In the factory setting, the drive starts with a pulse frequency of
4 kHz并自动降低脉冲频率至AS-
加载时社交所需的频率。当负载解除
creases, the pulse frequency is increased automatically up to
4kHz. The values of the rated current apply to a pulse frequency
of 2 kHz and an ambient temperature of 40 °C (104 °F) and are
reached at any time by the automatic adaptation of the output
pulse frequency.
