摘要
厂用电6 kV/10 kV系统安全可靠切换是一些发电机重要辅机正常工作的前提。以MFC2000-6型厂用电快切装置为例,叙述了快切装置各种切换方式在实际生产中的应用和存在的问题,对MFC2000系列快切装置典型切换失败的事故进行了探讨,并结合生产实际提出了防范措施,以期为同类电厂在厂用电快切装置应用方面提供借鉴。
The safe and reliable switching of plant electricity 6 kV/10 kV system is the premise of normal operation of some important auxiliary generators.Taking the plant electricity quick-switching device in Type MFC2000-6 plant as an example,the application and existing problems of various switching modes of quick switching device in practical production are expounded.The typical switching failure of the quick-switching device of MFC2000 series is discussed,and prevention measures are put forward combined with the actual production,so as to provide reference for similar power plants in the application of plant electricity quick switching device.
