网电压就会上升。在这种情况下,异步电动机将变成异步发电机,负载的机械能将转换为电能并反馈给变频器。但当上述馈电能量过t there may be high induced voltage present on the floating non-earthed end. However, there is a benefit in the fact that there will be no circulating current in the cable which improves the cable's ampere rating. This i 额定流量。由于流体具有动量和一定程度的可压缩性,流量的急剧变化将导致管道中的压力过压或过高的冲击,以及“气蚀”。压力
