摘　　要：笔者提出一种基于模块化真空断路器串并联结构的大容量高压断路器,该断路器通过均压组件将3个40.5 kV断路器模块串联成126 kV高压断路器,同时通过紧耦合空心电抗器对断路器模块并联,实现自动均流和限流功能。并对串并联模块化断路器设计的可行性进行研究试验,主要包括对设备的绝缘试验、均流和限流试验、开断试验、机械操作试验进行考核验证。对试验数据进行分析和整理,验证了串并联模块化断路器设计的可行性与合理性。This paper presents a new design of large-capacity high-voltage breakers base on series-parallel structure vacuum circuit breakers. In this design, 126 kV high-voltage circuit breakers is composed of d0.5 kV circuit breakers module by capacitance, a tightly-coupled reactor which has a small consumption in normal working state is adopted to connect with two paralleled breakers. This combination can effectively achieve the function of automatically current-sharing and current-limiting. The working principle of the design is verified through research tests. Including the insulation testing, paralleled and limiting current testing, break testing,verify the operation of machinery, and analysis of test data.
