In order to solve the problem of the phase inconsistent protection of refusing action whensplit-phase breaker travelling in the middle and the auxiliary contact remaining correspondently in the middle state make phase inconsistent protection of refusing action, this paper proposes a new method for breaker inconsistent protection based on two-position relay. Auxiliary contact of breaker is switched in open and close loop for two-position relay, breaker auxiliary contacts are used to drive the two-position relay, and contacts of two-position relay are used to make a three phase inconsistent protection. This method can hold the state of breaker on and off state by itself, which overcomes the auxiliary contacts cannot close when the breaker travels in the middle state, and ensures action reliability of the phase inconsistent protection when breaker is in no-on and no-off state.
