励磁涌流抑制器在海上石油平台的应用

Application of Inrush Suppression in Offshore Oil Platform

励磁涌流影响着海上石油平台电力系统的安全稳定运行。由于其引发的保护误动作、开关跳闸、电网冲击等,一直是电气人员很关注的问题。本文分析了励磁涌流产生的原因,在给变压器施压时通过控制磁路不饱和来抑制励磁涌流。采取的抑制策略是控制开关分合闸时刻在施加电压的同一初相位,保证合闸形成的偏磁抵消分闸后存在剩磁。

Inrush current impact on the safe and stable operation of power systems for offshore oil platforms.Because of the protection of their initiation malfunction switch tripping,power shock,It has been very concerned about the problem electrician.This article analyzes the causes of inrush current generated,when the transformer pressure by controlling the magnetic circuit is not saturated to suppress the magnetizing inrush,the suppression strategy is to take points off control switch in the same time in the early phase of the applied voltage,to ensure the presence of residual magnetism magnetic bias offset opening formed after closing.
