5. one kind three inlet wires, one mother power distribution control system as described in claim 1, which is characterized in that busbar breaker has two
Secondary source switching and divide-shut brake function, physical circuit connection relation is：Control system further include including secondary power supply switching after
Electric appliance, mother closing time relay, busbar breaker signal extension intermediate relay and mother tripping intermediate relay；It is described
The coil of mother power transfer relay takes electricity on II sections of busbares, when II sections of busbares are charged, mother power transfer relay
Coil energized action, first pair of normally opened contact are closed, and mother control loop is charged；When I sections of busbares are charged, 4L1 takes electricity to pass through
Mother power transfer relay second makes normally-closed contact mother control loop charged；4th pair of normally opened contact of the first breaker
It connects the 4th pair of normally-closed contact of the second breaker, the 5th pair of normally-closed contact of the first breaker connects the 5th of the second breaker
To normally opened contact, it is above-mentioned connect respectively after it is in parallel again after connect with second pair of normally-closed contact of busbar breaker after access mother conjunction
On lock time relay coil, the first couple delay normally opened contact of mother closing time relay seals in the combined floodgate of busbar breaker
Circuit；It connects between mother closing time relay and mother closing circuit electrical interlocking contact；First power monitoring relay
The 5th pair of normally opened contact connect with the 5th pair of normally opened contact of second source supervisory relay after with busbar breaker the 3rd
It is accessed after connecting to normally opened contact on mother tripping intermediate relay coil, the first couple of mother tripping intermediate relay is normally opened to be touched
Point seals in the sub-gate circuit of busbar breaker.
