海缆铺设装置中升压变压器的合闸过电流问题

On the Switching-on Overcurrent of Step-up Transformer abord Cable-Laying Ship

在为胜利油田研制海底电缆铺设装置过程中 ,曾发生升压变压器合闸时过电流跳闸问题。作者分析了产生这巨大励磁涌流的原因 ,后经采取有效措施解决了这一实际问题。

In the process of developing submarine cable laying installation for Shengli Oil Field,a certain problem has occurred with overcurrent tripping during switching on of step up transformer.In this paper the causes of huge excitation current are analysed and the effective measures taken to resolve this problem are also presented.
