长北中央处理厂电机远控系统防雷改造应用

Application of Lightning-protection Reform of the Motor Remote Control in Changbei Central Processing Plant

针对长北中央处理厂ABB的电机远控系统INSUM,由于设计缺陷而易遭受雷击而造成INSUM系统崩溃,进而导致INSUM系统所控电机发生失效的故障情况,提出了加装光电隔离及浪涌保护的解决方案,从根本上消除了雷击的影响,提高了系统的稳定性,保证整套系统的可靠运行,减少了人工操作及巡检次数,消除了现场安全隐患,确保了天然气生产正常进行。

For ABB motor remote control system INSUM in changbei central processing plant, INSUM system elue to design faultiness and lighting stroke leads to breakdown and then leads to INSUM system controlled by the motor to lose efficacy. Put forward a overcoming plan to add photoelectric isolation and surge protection, eliminate lightning stroke effect from the foundation, increase the system stability, ensure safe operation for the complefe system, reduce frequency of manual operation, eliminate hidden trouble in safety for site and ensure nomal aperation for natural gas production.
