Source device b1 puts into commencement of commercial operation, and now, u1 is responsible for monitoring the voltage of accumulator plant (namely between dc bus+m ,-m
Voltage).
When the accumulator battery voltage of the first accumulator power source apparatus b1 is less than setting value, first pair of built-in relay of u1
Time delay normally opened contact 11-12,13-14 action closes (delay time can adjust, 5～20 seconds), and conducting 2jc+, 2jc- vacuum connects
The coil dc24v electric power loop of tentaculum, 2jc+, 2jc- major loop closes, and the second accumulator power source apparatus b2 accesses+m ,-m direct current
Bus；Now two accumulator power source apparatus short time all access+m ,-m dc bus, due to connecing of 2# accumulator power source apparatus
Enter ,+m ,-m busbar voltage recovers normal.
After 2jc+, 2jc- closure, its auxiliary contact x3-x4 is closed at, the k1 actuating of relay, and its normally-closed contact 1-3 breaks
Open, 1jc+, 1jc- coil dc24v positive pole power-off, 1jc+, 1jc- major loop disconnect, the first accumulator power source apparatus b1 exit with+
The connection of m ,-m dc bus；When second couple of built-in relay normally open contact 13-14 of u1 closes, conducting indicator lamp (band ring sound
Function), indicator lamp is lighted and is sent alerting tone, notifies operations staff.
After operations staff investigates thoroughly problem, first press an2 button, reliable input the second accumulator power source apparatus, then press again
Lower an1 button, an1 releases self-locking, initial (disconnection) position of rebounding, and the first accumulator power source apparatus b1 safely and reliably exits fortune
OK, flame-proof type integrated power source apparatus are powered by the second accumulator power source apparatus b2.
Because the long-term parallel running of accumulator power source apparatus has an impact for service lifetime of accumulator, and safety in operation does not have
Secure；And the control device employed in the present invention in many set accumulator power source apparatus it is ensured that only a set of storage battery
Source device is powered to feeder equipment, and other a few set accumulator plants are in hot stand-by duty；So substantially prolongs this one
Change the back-up source power-on time of supply unit, beneficial to user, reasonable selection batteries quantity is needed according to scene.
