摘　　要：某公司输煤母线采用MFC2000型快切装置,在事故情况下,只能进行单向快切,即主用切换至备用。当6 kV输煤母线需要由备用电源供电时,快切装置的事故切换功能失去作用。当该备用电源故障时,6 kV输煤母线不能及时转由工作电源供电。为此,文章介绍了厂用电快切装置双向事故切换的改造过程。A company's coal transportation bus adopts MFC2000 type fast switching device.In the event of an accident,it can only perform one-way fast switching,that is,the main switch to the standby.When the 6 kV coal transmission bus needs to be powered by a backup power source,the accidental switching function of the fast switching device loses its effect.When the standby power supply fails,the 6 kV coal transmission bus cannot be transferred to the working power supply in time.To this end,the transformation process of the two-way accident switching of the factory electrical fast switching device was introduced.
