摘　　要：依据相关技术规范要求,通过对变电站隔离开关开断状态下其两侧电压值的对比计算分析,揭示了等电位操作实质是变电站隔离开关在开断后、合闸前,其两侧所存在的电压,不会影响用该隔离开关安全转换电流的操作。通过隔离开关安全隔离故障断路器的实例,进一步说明深刻理解、灵活运用等电位操作机理的重要性。According to the related technical specifications, through the calculation on both sides of the substation disconnectors in breaking state ,the essence of equipotential operation is exposed. The essence is that the both sides voltage value of disconnectors after breaking and before closing don＇t affect switching current safely. By the example of using disconnectors to isolate circuit breaker,the importance of profound understanding and flexible use of equipotential operation mechanism be description profoundly.
