A phases bus-bar and the N rows of the first electric power system, and the second power supply system are connected respectively in the both ends of the 3rd branch road and the 4th branch road
A phases bus-bar and the N row of system, therefore, there is voltage at the 3rd branch road both ends, and the first main switch QF1 is powered, and its normally-closed contact is by electric current
Adhesive effect and disconnects, i.e. C1 and C2 both ends disconnection, the coil ends A 3 and A4 for making second contactor KM3 do not have voltage, make
The main contacts (the second branch road) of second contactor disconnects, meanwhile, the normally-closed contact of second contactor is also acted on without adhesive, A1
Normally off is remained with A2 both ends, makes first contactor KM1 coil both ends B3 and B4 have voltage, to ensure the first contact
Device KM1 main contact is constantly in closure state, and tie point turns on, now, tie point and secondary returning in primary circuit
The 3rd branch road conducting in road, by the first electric power system powering load.
(3) when the first main switch QF1 is disconnected, and the second main switch QF2 is closed, i.e., powered using the second electric power system, by
A phases bus-bar and the N rows of the first electric power system, and the second power supply system are connected respectively in the both ends of the 3rd branch road and the 4th branch road
A phases bus-bar and the N row of system, therefore, there is voltage at the 4th branch road both ends, and first contactor KM1 coil both ends B3 and B4 are all the time
There is no voltage, its normally-closed contact is constantly in closure state, i.e. B1 and B2 conductings in the 4th branch road, meanwhile, in tie point
First contactor KM1 main contacts be also off all the time.Because the first main switch QF1 disconnects, its normally-closed contact does not have
There is adhesive, therefore, C1 and C2 in the 4th branch road are constantly in conducting state, now, second contactor KM2 coil
There is voltage at A3 and A4 both ends, adhesive second contactor KM2 normally-closed contact, disconnect the A1 in the 3rd branch road and A2, meanwhile, the
The main contact of two contactors is constantly in closure state, the conducting of the second branch road, now, the second branch road in primary circuit and secondary
The 4th branch road conducting in loop, by the second electric power system powering load.
(4) moment switched in the first main switch QF1 and the second main switch QF2, normally closed due to first contactor KM1 are touched
The coordinated signals of this two groups of normally-closed contacts of point B1 and B2, second contactor KM2 normally-closed contact A1 and A2, even if ensure that in electricity
The moment of source switching is also not present two electric power systems and gives electric situation simultaneously, i.e. any time has and only one group of electric power system
Power supply.
Control of power supply system circuit provided by the utility model, by by the main switch of one of electric power system and contact
The normally-closed contact series connection of device, accesses the control loop of another electric power system, and by the contactor of another electric power system
The mode that normally-closed contact is connected with the coil of the contactor of first electric power system, it can ensure that either two sets of electric power systems are same
When work, or only wherein the work of a set of electric power system when, all only a set of electric power system gives the illumination system of whole low-pressure chamber
Even load of uniting provides voltage, ensure that low pressure room lighting, the security and continuity of control loop electricity consumption, also contributes to simultaneously
Solve a set of electric power system power taking, and when electric power system does not work, the limitation that illuminator even load can paralyse, meanwhile,
Help solve the problems, such as that two sets of illuminator costs of design are high, further, be also beneficial to realize that illumination and the unified of distribution are controlled
System, has been effectively ensured the stability of electric power system.
