The right end of the 302 horizontal arc groove in top of backup power source operating mechanism mounting rack, the top of the actuating rod 304 pass through hinged
Pin acts to the right in the sliding slot of action link rod 306, drives action link rod 306 for counterclockwise rotation, so that action link rod
The rotation square shaft 308 on 306 tops rotates in an anti-clockwise direction, thus drive rotation square shaft 308 on moving contact move downward and with
The static contact of lower part closes a floodgate, and after in-place closing, the backup power source on the backup power source rotation square shaft 308 acts stop member 309
It opens the auxiliary switch 307 in left side and powers off electromagnet, contact pressure can give action link rod 306 after being closed a floodgate due to backup power source
One reaction force is rotated clockwise action link rod 306, due to swivel pin on backup power source operating mechanism mounting rack 302
3031 position-limiting action, so that actuating rod 304 can not be rotated clockwise and being automatically locked at closing position makes standby electricity
The combined floodgate in source is in stable combined floodgate hold mode；
As shown in Figure 2 and Figure 3, after the intelligent controller of double power supply automatic transfer switch provides common power supply sub-gate signal,
The opening coil of common power supply conversion of electromagnetic iron obtains electric, conversion of electromagnetic iron actuating strut 103 is released, by common power supply conversion of electromagnetic
Iron actuating strut 104 is pushed out to the left end that swivel pin 1031 is in the common 102 horizontal arc groove in top of power operation mechanism mounting rack,
103 upper end of actuating rod acts to the left simultaneously, and the rotation square shaft 108 on 106 top of actuating strut is forced to turn clockwise
It is dynamic, so that the moving contact on rotation square shaft 108 be driven to move upwards and the static contact separating brake with lower part, when separating brake in place after, institute
The common power supply movement stop member on common power supply rotation square shaft stated opens the auxiliary switch of side and makes common power supply conversion electricity
Magnet power-off, after commonly using power supply separating brake in place, so that common power supply rotation square shaft 108 is relative in movement strut 105 and strut
The effect of compressed spring produces torque counterclockwise, at this time due to swivel pin 1031 on common power operation mechanism mounting rack 102
Position-limiting action so that common power supply action link rod 106 can not rotate counterclockwise and being automatically locked at open position makes common electricity
Source is in stable separating brake hold mode, no matter in this way, they can be in stabilization when dual power supply is in combined floodgate or open position
Self-sustaining state, while mechanism may be implemented close a floodgate when increase contact pressure, so that dual power supply is born bigger tolerance in short-term
The time of electric current and longer KA Rms, when separating brake, can increase clearance between open contacts, be conducive to dual power supply disjunction switching current
When arc extinguishing so that the dual power supply of this structure have excellent electric property, substantially increase the job stability of dual power supply.
Simultaneously as the effect of interlocking connecting rod, when common power supply is in combined floodgate situation, backup power source cannot close a floodgate, and work as backup power source
When in combined floodgate situation, common power supply cannot close a floodgate, and ensure that the case where dual power supply is not in two road power supply short circuit, this pair electricity
Source has the function of common power supply and backup power source separating brake simultaneously, the maintenance powered off in favor of user to loaded line and guarantor
It supports.
The common power supply close a floodgate and the switching motion principle of backup power source separating brake with it is upper identical.
It should be understood that above-described embodiment is merely examples for clearly illustrating the present invention, and it is not
Restriction to embodiment can also be made on the basis of the above description for those of ordinary skill in the art
Other various forms of variations or variation, there is no necessity and possibility to exhaust all the enbodiments, and is thus extended
Obvious changes or variations out still in the protection scope of the utility model among.
