摘　　要：2007年06月01日贵广直流肇庆换流站阀冷系统的一次切换过程中,本应保持合位的两处小开关意外跳开,造成阀冷主泵及主泵电源失去冗余。分析了该异常现象的成因,指出贵广直流肇庆换流站阀冷系统切换控制当前存在的缺陷,讨论了相应可采用的解决措施,并对实际采用的解决方案进行了说明。During one switching course of Zhaoqing Converter Station＇s valve cooling system, two switches that should have been kept closed tripped by accident which made the valve cooling system lose its redundancy. The paper analyses the reason that caused the abnormal phenomenon and points out the living defects of the valve cooling system＇s switching control. Also, it discusses the available ways that can solve the problem and introduces the way that is actually adopted.
