Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described.Following examples are only used for clearly illustrating this
The technical scheme of utility model, and protection domain of the present utility model can not be limited with this.
As shown in figure 1, concrete operating principle is as follows:
The switching principle of generator operation state:Mains failure, now first, second and third air switch 1,2,3 is closure
, generator operation, B, C that the pull-in winding of fourth, fifth, six A.C. contactors 7,8,9 is directly connected to electromotor are alternate, because
This fourth, fifth, six A.C. contactor 7,8,9 works(Normally closed auxiliary contact disconnects), export end subscriber and use generator power supply, generate electricity
Machine power in the case of as the pull-in winding of first, second and third A.C. contactor 4,5,6 is by fourth, fifth, six ac contactors
The normally closed auxiliary contact of device 7,8,9 is connected to B, C phase of civil power, thus be responsible for connection civil power in first, second and third ac contactor
Device 4,5,6 can not possibly work.After the power transmission of city power recovery, A, B, C three-phase is electrically connected to the input of the first A.C. contactor 4,
Such as 1,2 feet of the first time delay relay of figure 11 have been connected in B, C phase by connecting electric wire, the first time delay relay 11
Work, trigger are clocked(Setting delay time 60 seconds), while B phase power supplys are connected to the 8 of the first time delay relay 11
Foot, and the 6 feet connection of the inside normally-closed contact by the first time delay relay 11 and the first time delay relay 11, the
7 feet of the 6 feet connection first circulation control time relay 10 of one time delay relay 11, first circulation control time relay
The 2 feet connection zero line of device 10 is arranged, and now the 2-7 feet of first circulation control time relay 10 are connected 220V electricity and make first circulation control
The time relay processed 10 is also worked simultaneously, beginning of clocking(Setting starts adhesive after 45 seconds, work was discharged after 3 seconds, delay working
The purpose of 45 seconds is to consider that line failure is unstable, is not tripped within 30 seconds substantially it can be assumed that civil power is normal), after 45 seconds, 10 inhale
Close 3 seconds, 6 feet and 8 feet connect shutdown relay by internal normally opened contact, shutdown relay work connects shutdown electric magnet sending out
Motor stops working, fourth, fifth, six A.C. contactors, 7,8,9 pull-in winding dead electricity after electromotor is flame-out, and fourth, fifth, six exchanges connect
Tentaculum 7,8,9 quits work, and normally-closed contact closure has connected the pull-in winding power supply of first, second and third A.C. contactor 4,5,6,
First, second and third A.C. contactor 4,5,6 works, and city is electrically connected to outfan, and now user begins to use civil power, civil power
After 60 seconds, 11 action of the first time delay relay, internal 6 foot and 8 feet disconnect electricity, have cut off first circulation control time relay
The power supply of device 10, first circulation control time relay 10 lose power supply and quit work.Civil power working condition is entered now.
Generator operation state is priority status, the starter-generator in the case where civil power does not have a power failure, and the system will be from
It is dynamic to be switched to generator powered state, at this moment if it is desired to using civil power, after electromotor need to being closed or air switch being left behind again
Close.
The switching principle of civil power working condition:Now electromotor is in halted state, when mains failure, first, second and third
A.C. contactor 4,5,6, first circulation control time relay 10, the first time delay relay 11 are due to pull-in winding dead electricity
And quit work, the normally-closed contact of the 3rd A.C. contactor 6 is connected, when manual/auto permutator is in closure state, the
1,2 feet of two time delay relays 13 have connected 24 volts of unidirectional currents, and the time delay of clocking of the second time delay relay 13 starts(If
Fix time 20 seconds), while second circulation control time relay 12 is by 8 feet and 6 inside the second time delay relay 13
Foot normally-closed contact has also been connected 24 volts of unidirectional currents and has been started working(After setting second circulation control time relay 12 connects unidirectional current
Beginning action in 15 seconds, 3 seconds movement times), second circulation control time relay 12 is internal in having connected for 3 seconds for action
6th, 8 foot, so as to connect the pull-in winding of starting relay, starting relay works 3 seconds, drives 3 seconds starter-generators of motor
Work starts to generate electricity, fourth, fifth, six A.C. contactors, 7,8,9 adhesive after electromotor normal power generation, and fourth, fifth, six exchanges connect
The normally-closed contact of tentaculum 7,8,9 disconnects the pull-in winding power supply for having cut off first, second and third A.C. contactor 4,5,6, first and second,
City can not possibly be electrically connected to outfan by three A.C. contactors 4,5,6, and user begins to use generator powered.After 20 seconds, second prolongs
When 13 action of the time relay, cut off the power supply of second circulation control time relay 12, second circulation control time relay
12 dead electricity of device quits work, now into generator powered state.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, some improvement and deformation can also be made, these change
Enter and deform also to should be regarded as protection domain of the present utility model.
