摘　　要：提出一种提高隔离开关转换电流开合能力的方法,通过在主导电回路中加装并联辅助回路,使得转换电流的开合由并联辅助回路中的真空断路器进行,可大幅提高隔离开关的转换电流开合能力,满足特高压串补用旁路隔离开关的需要。该方法使得电弧密封在真空灭弧室内部,完全消除了电弧对外部设备产生的影响。基于该研究成果研制的特高压旁路隔离开关已通过型式试验验证,并成功应用于特高压工程。A method is proposed to improve transfer current switching capacity for bypass disconnectors by setting auxiliary circuit paralleled with main circuit. Because of switching by vacuum circuit breaker in auxiliary circuit, transfer current switching capacity of disconnectors can be improved significantly, and meet the demands of bypass disconnectors used for ultra high vohage（UHV） series compensation. Therefore arc can be enclosed in vacuum interrupters, the influence on external devices will be eliminated. The UHV bypass disconnectors, developed based on this research, has passed the type test, and has successfully applied in UHV project.
