摘要
南海某平台的中压配电系统采用了新型Synchro Teq MV励磁涌流抑制器,集成安装在中压控制段上。原有的中压控制柜往往对中压变压器进行直接分合闸控制。由于变压器自身的电感效应,在启动时会产生很大的励磁涌流,造成保护装置误动作。本文介绍的新型励磁涌流抑制器可以控制断路器分合闸角度,以最大限度地消除励磁涌流,保证用电质量。
The SynchroTeq MV inrush restrainable device is used in the medium voltage power system of a platform in the South China Sea,which is mounted in the medium voltage control cabinet. The medium voltage control cabinet was often used for direct switching control of medium voltage transformers in the past time. When the medium voltage transformer starts up,it will produce a large inrush current which will cause the protection device to operate by mistake due to inductance of the transformer. The new inrush restrainable device can control the cutting-phase and entering-phase of the circuit breaker,so as to maximum eliminates the inrush current and ensures the power quality.
