3 相交流电机软启动

概览

传统技术下，3 相交流电机以星形配置启动，然后切换到三角形配置，以减少励磁涌流和机械应力，从而延长电机寿命。 然而，这种方法需要额外的布线，而且切换机制也较为复杂。 另一种方案则是在两相上采用相位角控制技术，通过将相位角从 360° 减小到 0°，实现电机的软启动（也可选择软停止）。 继电器用于在运行模式下旁路双向可控硅/晶闸管，从而消除损耗并提高效率。

系统优势：

  • 无需星形三角接线，从而简化了布线并降低了电机成本
  • 通过减少机械应力延长电机寿命
  • 显著降低励磁涌流，并可对其持续时间进行精确控制
  • 使用简单的电位器即可轻松进行参数调整
  • 可选配 RS-485 或 CAN 等总线接口进行控制
  • 提供可选的用户友好型 GUI（图形用户界面），支持智能手机蓝牙连接访问
