Description of drawings
Fig. 1 is a circuit connection diagram of the present utility model.
Number in the figure is as follows: general supply 1, civil power incoming line 2, acoustic-optic alarm 3, UPS are to the normally open contact KM-1 of load output 4, general supply circuit breaker Q F1, UPS output circuit breaker Q F2, civil power circuit breaker Q F3, UPS output contactor KM, city electric contactor KM1, UPS fault detect auxiliary relay KA, UPS output contactor KM, the normally closed interlock KA-1 of the normally closed interlock KM1-1 of city electric contactor KM1, normally open contact KM1-2, normally open contact KM1-3, UPS fault detect auxiliary relay KA
Embodiment
Show among the figure, the utility model is that general supply circuit breaker Q F1, UPS output circuit breaker Q F2 has been installed respectively in the front and back end of ups power, and introduced standby civil power incoming line 2, the input of civil power incoming line 2 has civil power circuit breaker Q F3, and the output of civil power incoming line 2 is connected on the rear end of UPS output circuit breaker Q F2.Be parallel with UPS fault detect auxiliary relay KA at the UPS output, in the civil power incoming line, be parallel with UPS output contactor KM, city electric contactor KM1.The normally closed interlock of above-mentioned these relays and contactor, normally open contact are connected on respectively in UPS outlet line and the civil power incoming line.
Below in conjunction with function of the present utility model structure of the present utility model is elaborated.
Automatic switchover civil power powering load when this device can be realized the UPS fault, and maintenance the time can not stop load and withdraws from the function that ups power overhauls fully.
1.UPS unit state during operate as normal:
Connect general supply circuit breaker Q F1, ups power gets; Connect UPS output circuit breaker Q F2 again, UPS fault detect auxiliary relay KA coil gets electric, and its normally-closed contact KA-1 disconnects, and city's electric contactor KM1 coil must not; Connect civil power circuit breaker Q F3, UPS output contactor KM coil gets, its normally open contact KM-1 closure, load is normally exported power supply through UPS, at this moment must not because of city's electric contactor KM1 coil, its normally opened contact KM1-2, KM1-3 disconnect, and civil power incoming line 2 can not be to load output 4 power supplies of UPS, acoustic-optic alarm 3 access failures.
2.UPS automatic switching function during fault:
When the UPS fault, UPS output dead electricity, UPS fault detect auxiliary relay KA dead electricity, its normally closed interlock KA-1 closure, city's electric contactor KM1 coil gets electric, and its normally-closed contact KM1-1 disconnects, the UPS output contactor KM coil losing electricity of serial connection mutually, its normally opened contact KM-1 disconnects, and the normal output loop of UPS disconnects.At this moment get owing to city's electric contactor KM1 coil, it is connected on the normally open contact KM1-2 closure of the city electric contactor KM1 in the civil power incoming line 2, the civil power incoming line is connected, and civil power is delivered to the load output 4 of UPS through the normally open contact KM1-2 of civil power circuit breaker Q F3, city electric contactor KM1.
The phase line that civil power circuit breaker Q F3 is connected must be a homophase with the phase line of the output of UPS when carrying bypass work, otherwise may occur because the phase sequence difference makes the accident of voltage rising, burning apparatus.Method of calibration: get to the bypass operating state during UPS operate as normal, which homophase mutually then is the phase line that civil power circuit breaker Q F3 is connected in the power supply that verification is exported at this moment and the UPS input power supply three-phase.
3. load is not shut down and is carried out the UPS turnaround of unit:
When equipment that mostly load is to shut down; this moment is when thinking that stopping UPS fully overhauls; can disconnect the UPS output circuit breaker Q F2 on the UPS output loop; UPS fault detect auxiliary relay KA dead electricity; its normally closed interlock KA-1 closure, city's electric contactor KM1 coil gets electric, and its normally closed interlock KM1-1 disconnects; cause UPS output contactor KM coil losing electricity, its normally open contact KM-1 disconnects the UPS output loop.At this moment because of the normally open contact KM1-2 closure of city electric contactor KM1, civil power incoming line 2 has been connected, and 220V voltage is delivered to load through the normally open contact KM1-2 of civil power circuit breaker Q F3, city electric contactor KM1.After disconnecting the general supply circuit breaker Q F1 of UPS input general supply 1 afterwards, the UPS device is withdrawn from from current supply circuit fully, can carry out service work.
After maintenance finishes, the general supply of closing earlier circuit breaker Q F1, UPS starts working, the UPS that closes output circuit breaker Q F2, the UPS output loop powers on, UPS fault detect auxiliary relay KA adhesive, city electric contactor KM1 coil losing electricity, civil power incoming line 2 disconnects, and the contactor of UPS output simultaneously KM coil gets electric, and process UPS output is to the load normal power supply.
4. when switching to the civil power operating state, UPS is in the fault or the alarm of inspecting state:
When UPS was in fault or inspecting state, load was to be in the mains-supplied state.At this moment city's electric contactor KM1 get electric, its normally open contact KM1-3 closure, the acoustic-optic alarm that is in series with it 3 is connected, acoustic-optic alarm 3 is reported to the police, alert UPS is in fault or inspecting state, enables in time to get in touch the maintenance personal and checks.
