蓝河电气DDX1短路电流限制器南海某油田群扩容项目中正确开断

Date： 2018-07-27
Views: 20

 我公司生产制造的一台短路电流限制器（下文简称限流器）于2012年9月23日在中海油（中国）有限公司湛江分公司南海某油田群扩容项目中投入运行。2018年5月28日凌晨6点左右，因线路短路故障，故障电流超过了限流器的电子控制器的整定值（故障录波系统能查到故障时的电流值），限流器快速动作，限制短路电流并开断，使电气设备免遭遇短路电流峰值的冲击而损坏。

限流器安装至今6年有余，仍能安全可靠动作，达到了设计要求，限制系统短路电流到开关设备的遮断容量之下，保护了电气系统设备的安全，得到了用户的肯定和表扬。
