Accompanying drawing explanation
Fig. 1 is the electrical block diagram of stand-by power supply of the present invention.
Fig. 2 is the circuit theory diagrams of power transfer device of the present invention.
Detailed description of the invention
The present invention will be further described with specific embodiment below in conjunction with the accompanying drawings.A kind of electrical installation of band stand-by power supply
Platform, including electrical test bench, main power source interface, stand-by power supply and power transfer device, main power source interface and stand-by power supply respectively
The supply port of testing stand it is connected to by power transfer device.
As it is shown in figure 1, the stand-by power supply of the present embodiment accumulator that includes being sequentially connected with, capacitor filter, high frequency are complete
Bridge inverter circuit, high frequency transformer, rectification circuit, capacitor filter, power frequency full bridge inverter and LC filter circuit.Electric power storage
Pond provides stable DC voltage V1, this DC voltage V1 to obtain voltage V2 through capacitor filtering, by V2 supply high frequency full-bridge inverting
Circuit, DC low-voltage inversion is high-frequency ac voltage V3 by this inverter circuit, and V3 supply high frequency transformer boost is obtained high frequency
Ac high-voltage V4, then by full-bridge rectification, finally give high direct voltage V5.High direct voltage V5 filters miscellaneous through capacitor filter
Ripple, it is thus achieved that high direct voltage V6, supplies power frequency full bridge inverter by high direct voltage V6, it is thus achieved that ac high-voltage V7, eventually through LC
Alternating voltage V8 needed for filter circuit acquisition.This stand-by power supply be provided that stable 220V, 50HZ alternating voltage and
300V DC source, output is stable, cheap.
Stand-by power supply provides alternating voltage and the 300V DC source of stable 220V, 50HZ, and output is stable.Accumulator
Be in charged state when main power source is normal, charge complete after be in holding state, just come into operation during main power source power-off.
As in figure 2 it is shown, the power transfer device of the present embodiment include being connected to main power source interface auxiliary reclay 1KC,
2KC, 3KC, and main power source controls loop and stand-by power supply controls loop；Main power source interface passes through chopper 1QF and main power source
Controlling loop and be connected to supply port N of testing stand, main power source controls moving together contact 2KC, the dynamic circuit connector that loop includes being sequentially connected with
Contact 3KC, dynamic circuit breaker auxiliary contact 2KM, contactor coil 1KM；Stand-by power supply controls loop by chopper 2QF and stand-by power supply
Being connected to supply port N of testing stand, stand-by power supply controls loop and includes being sequentially connected with dynamic circuit breaker auxiliary contact 1KM, break contact
1KC, 2KC, 3KC, contactor coil 2KM and main contact 2KM.
When there being stably normal power supply input, chopper 1QF, 2QF are in A.C. contactor 1KM main contacts and connect position
Put, by working power to user's normal power supply.Owing to auxiliary reclay 1KC, 2KC, 3KC are charged, therefore 2KC, 3KC moving together contact is closed
Closing, 1KC, 2KC, 3KC break contact disconnects, and therefore controls loop L1 → 2KC → 3KC → 2KM → 1KM → N charged, therefore contacts
Coil 1KM is charged for device, and dynamic circuit breaker auxiliary contact 1KM disconnects, contactor coil 2KM dead electricity, and dynamic circuit breaker auxiliary contact 2KM closes, standby
Power supply is in resting state.
When working power power-off suddenly for some reason, due to auxiliary reclay 1KC, 2KC, 3KC dead electricity, 2KC, 3KC dynamic circuit connector is touched
Point disconnects, and corresponding 1KC, 2KC, 3KC break contact closes, contactor coil 1KM dead electricity, and dynamic circuit breaker auxiliary contact 1KM closes, because of
It is charged that this controls loop L1 → 1KM → 1KC, 2KC, 3KC → 2KM → N, and therefore contact coil 2KM is charged, makes main contact 2KM close
Close, change stand-by power supply into and power.Simultaneously after contactor coil 2KM action, its dynamic circuit breaker auxiliary contact 2KM disconnects, and prevents catalyst
Coil 1KM maloperation, prevents paired running.
After working power is recovered, the charged action of auxiliary reclay 1KC, 2KC, 3KC, 2KC, 3KC moving together contact closes,
1KC, 2KC, 3KC break contact disconnects, contactor coil 2KM dead electricity action so that it is main contact 2KM disconnects, and stand-by power supply stops
To customer power supply, recover resting state.Dynamic circuit breaker auxiliary contact 2KM close, therefore control loop L1 → 2KC → 3KC → 2KM →
1KM → N is charged, and therefore contactor coil 1KM is charged, and dynamic circuit breaker auxiliary contact 1KM disconnects.
This stand-by power supply has automatic operation mode and manual work pattern, and automatic operation mode principle is explained as above, real
Now haul oneself willingly into runback, when external power supply occurs abnormal, be rapidly switched to stand-by power supply, use stand-by power supply to power, it is to avoid suddenly
The power-off damage to equipment.When surrounding does not has external reliable source of power, stand-by power supply can use manual mode, directly uses standby
Power supply is powered, it is ensured that equipment can run under power down mode equally.
The present embodiment also includes illuminator, and illuminator is connected to testing stand supply port.Illuminator shines for mobile
Bright lamp, including buckle and the support bar of the connection of lampshade, lamp socket, bulb and lamp socket, lamp socket outer surface has screw thread, table in lampshade
There are screw thread, lampshade and lamp socket spiral marking connection in face, and lamp socket is connect by screw with buckle and support bar, and bulb is arranged on lamp socket
On, movable illumination device, by support bar is internal and lower panels links to power supply, can be fixed on horizontal stroke by buckle by wire
On bar.Luminous lamp switch is on workbench front panel, and power supply is provided by main power source, is provided by stand-by power supply during main power source power-off.
Having rotation turning in the middle part of support bar, support bar has rotation turning, each turning can realize 360 degree as main cross bar junction
Rotate, realized the change of illumination direction by rotation.
For convenience of using, it is also possible to arrange hook on the table.The hook of the present embodiment has four and is evenly distributed in
Hanging on thing cross bar, each hook bearing strength is more than 25kg, and the base of hook is welded on extension thing cross bar, and the base of hook has rotation
Runner, it is achieved hook 360 degree of rotations along the z-axis direction, the convenient placement hung thing and fold aft hook.
