Focussing on the current sharing process of the paralleled circuit breakers with a high coupled split reactor(HCSR),we put forward the expressions of imbalance current of simply paralleled circuit breakers and the paralleled circuit breakers with HCSR.Conclusions could be drawn that the current limiting reactor and coupling coefficient of HCSR and the arc resistance of the circuit breakers were main factors that affected the current sharing results.In order to prove the onclusions above,the simulation models of HCSR and vacuum/SF6circuit breakers were established to simulate the current sharing of paralleled circuit breakers,and a synthetic circuit test of paralleled circuit breakers was also conducted.The simulation and test results are consistent with the analysis conclusions.The research results give a principle to choose the parameters of HCSR under different types of circuit breakers,and can be used to guide the design of paralleled circuit breakers with HCSR.
