摘要： An interlock apparatus of a ring main unit is provided. The interlock apparatus of the ring main unit may change a rotational motion of the shaft included in the circuit breaker to a rectilinear motion, and thus, the insertion hole may be opened or closed according to a closed or cutoff state of the circuit breaker. Accordingly, in the closed state of the circuit breaker, the control of a state of the disconnector is prevented.
