产品详情资料

 并允许操作员在电机运行时调整电机磁场电流。这为SFC型励磁机提供了便利，无需关闭电机，也无需在励磁变压器的几个分接头之间移动电缆。励磁电流调节励磁电流调节器模块还采用手动电位计调节励磁电流。然而，调节器提供闭环控制，以便自动调整VFC DC输出，以保持手动电位计设置的设定点磁场电流。此功能允许操作员将磁场设置为所需的磁场电流一次。然后调节励磁电流，以补偿由于励磁绕组加热或系统电压波动引起的励磁电阻变化。同步电机的主要无功功率贡献与励磁电流水平有关。如果希望在所有轴负载条件下大化同步电机的主导无功功率，请将励磁电流设置为尽可能高的值，而不超过其铭牌额定值。励磁电流调节是大化无功功率的理想选择，因为它允许操作员将励磁电流设置得非常接近额定值，而不必担心电流“爬行”on the door and allows an operator to adjust the motor field current while the motor is running. This provides the convenience over the SFC type exciter of not having to shut down the motor and physically move cables between several taps on the exciter transformer. Field Current Regulation The field current regulator module also employs a manual potentiometer for adjustment of the field current. However, the regulator provides a closed loop control so that the VFC DC output is automatically adjusted to maintain the set-point field current as set by the manual potentiometer. This feature allows the operator to set the field one time at a desired field current. The field current will then be regulated to compensate for field resistance changes due to field winding heating or system voltage fluctuations. The leading reactive power contribution of a synchronous motor is related to the level of field current. If it is desired to maximize the contribution of leading reactive power from the synchronous motor at all shaft loading conditions, set the field current as high as possible without exceeding its nameplate rating. Field current regulation is the ideal choice for maximizing the leading reactive power because it allows the operator to set the field current very close to rated and not worry about the current “creeping”
