A new design of optically controlled vacuum circuit breakers based on series-parallel structure is presented.In this design,one 126kV high-voltage circuit breaker is composed of three 40.5kV circuit breaker modules by voltage-sharing components.A tightly-coupled air 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 control signals are received and send byfiber optic.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.
