低压电动机防晃电模块的类型及参数设置

Type and parameter setting of anti-interference module for low voltage motor

供电网电压瞬间波动会造成电压瞬间降低,使正常工作且吸合的交流接触器释放,引起用电设备停机。低压电动机防晃电措施采用电动机综保防晃电再启动功能和安装防晃电模块,用来避免晃电引起运行设备停机。针对防晃电模块的类型和功能,文中分析了防晃电模块在分类、选型及应用中的注意事项,有助于掌握设备的性能、保障设备平稳运行。

The instantaneous fluctuation of the voltage in the power supply network will cause the instantaneous decrease of the voltage, release the AC contactor which works normally and actuates, and cause the shutdown of the electric equipment. The antiinterference measures of low-voltage motor adopt comprehensive protection of motor and anti-interference restart function and install anti-interference module to avoid the power interference causing the shutdown of operating equipment. Aiming at the types and functions of anti- interference module, this paper analyzed the matters needing attention in the classification, selection and application of anti- interference module, which is helpful to grasp the performance of equipment and ensure the smooth operation of equipment.
