    同时,石油化工行业的特点本身就是大通量、满负荷的连续运转,因而对电机设备的可靠性和稳定性要求极高,一旦发生事故,必须马上查找故障原因并及时消除,以保证及时恢复生产。锦化化工集团过去一直采用热继电器作为电动机的过载保护和控制元件,但由于元件质量和工艺的限制,已无法满足日益发展的工艺自动化的要求。为此,我们经过多年尝试和反复实践,最终选择了一种新型的电动机智能保护器(简称为电机保护器),作为电动机的保护元件,并取得了一定的使用经验。特别是我们在锦化新建的8万吨离子膜烧碱改造工程、12万吨离子膜烧碱工程、8万吨聚氯乙烯工程、8万吨环氧丙烷和5万吨粒碱等国家重点工程建设过程中,通过在低压配电系统使用了1600多台电机保护器,不但有效的保障了电机的安全运行、彻底取代了热继电器,而且利用先进的通讯技术,实现了部分电机控制的自动化,并取得了显著的经济效益,因此,下面就电动机保护器的工程应用作以简单介绍。
