Abstract：Integrated disconnecting circuit-breaker used in a half-circuit breaker wiring can simplify the conventional wiring design of a half-circuit breaker. It cancels either side or side of circuit breaker isolation switch. After reliability assessment analysis, the simplified wiring method of retaining the bus side isolation switch and canceling the line side one is determined. It basically simplifies the system wiring. It brings a new concept to the design and operation maintenance of substion.
