摘　　要：双确认高压交流隔离开关,通过对敞开式隔离开关低电位传动部位增加分合闸判别的姿态传感器,形成分合闸第一判据,操动机构内辅助开关分合闸信号形成第二判据,组成双确认信号,通过远方控制敞开式隔离开关进行分合闸操作,形成两路非同源信号共同来判别敞开式隔离开关是否分合到位。以GW4-126敞开式隔离开关为例,详细介绍双确认系统、双确认高压交流隔离开关的技术性能及参数要求。Double confirmation High-voltage alternating-current disconnectors, through the attitude sensor that increases the opening and closing discrimination of the open-type isolating switch low-potential transmission part, forming the first criterion of opening and closing, and the auxiliary switch opening and closing signal in the operating mechanism forms a second criterion. The double confirmation signal is formed, and the open and close switch is remotely controlled to perform the opening and closing operation, and two non-homologous signals are formed together to determine whether the open isolation switch is in place. Taking the GW4-126 open isolation switch as an example , the technical performance and parameter requirements of the double confirmation system and the double confirmation High-voltage alternating-current disconnectors were introduced.
