A mains supply passes through the change-over switch and inputs load. The controller is connected with the change-over switch and the first diesel generator. The first diesel generator is connected with the UPS. The controller is connected with the UPS. The UPS outputs electric energy to the load. The emergency electric-energy system can provide safe and reliable electric energy after the mains supply is cut off.
Description
Technical field
The utility model relates to the supply of electric power control field, particularly relates to a kind of emergency power system with diverter switch.
Background technology
Commercial power supply in the National Power System scope when commercial power supply breaks down, uses uninterrupted power supply as stand-by power supply at present, utilizes the batteries in the uninterrupted power supply to provide electric energy to the user; But because the finite capacity of storage battery in the uninterrupted power supply, and a period of time before the batteries electric energy runs low, spread of voltage can't guarantee to provide reliable emergency power supply.
The utility model content
The purpose of this utility model is to propose a kind of emergency power system with diverter switch, after the commercial power supply fault, can provide safe and reliable electric power supply.
The scheme that adopts is:
A kind of emergency power system with diverter switch comprises: controller, diverter switch, uninterrupted power supply and the first diesel engine generator;
Wherein, civil power is through described diverter switch input load; Described controller connects described diverter switch and described the first diesel engine generator; Described controller be connected the first diesel engine generator and connect respectively described uninterrupted power supply; Described uninterrupted power supply output electric energy is to load.
The utility model is after municipal power failure, and diverter switch disconnects, and starts simultaneously controller and devotes oneself to work by uninterrupted power supply, and first proof load uninterrupted power supply starts diesel engine generator work simultaneously; Because diesel engine generator needs about 10 minutes time from starting to stable operation, be to load supplying in during this period of time by uninterrupted power supply; After diesel engine generator stable operation, be exactly that diesel engine generator powers to the load by the rectifier in the uninterrupted power supply and inverter, the charge in batteries in the uninterrupted power supply simultaneously.Behind the city power recovery, switch to civil power by diverter switch again and power to the load, disconnect diesel engine generator and uninterrupted power supply.Safe and reliable electric power supply can be provided.
Can provide required electric energy to load in order to ensure, among embodiment, described emergency power system with diverter switch also comprises: the second diesel engine generator and alarm therein;
Wherein, described alarm connects described the first diesel engine generator and described the second diesel engine generator; Described the second diesel engine generator is connected with described controller.When the diesel engine generator fault was arranged, alarm sends reported to the police and notification controller; Other diesel engine generators of startup generated electricity after controller received alarm signal.
In order further to improve the reliability of electric power supply, in one of them execution mode, described uninterrupted power supply is on-Line UPS.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is another structural representation of the present utility model.
Embodiment
For ease of understanding the utility model, below in conjunction with accompanying drawing the utility model is described.
The utility model proposes a kind of emergency power system with diverter switch, please refer to Fig. 1, comprising: controller, diverter switch, uninterrupted power supply and the first diesel engine generator;
Wherein, civil power is through the diverter switch input load; Controller connects diverter switch and the first diesel engine generator; The first diesel engine generator connects uninterrupted power supply; Controller connects uninterrupted power supply; Uninterrupted power supply output electric energy is to load.
Operation principle of the present utility model is:
Under normal circumstances, UPS(Uninterruptible Power System, uninterrupted power supply) and diesel engine generator do not work, directly powered to the load by diverter switch by civil power; Diverter switch disconnects, and starts simultaneously controller and devotes oneself to work by uninterrupted power supply, and first proof load uninterrupted power supply starts diesel engine generator work simultaneously; Because diesel engine generator needs about 10 minutes time from starting to stable operation, be to load supplying in during this period of time by uninterrupted power supply; After diesel engine generator stable operation, be exactly that diesel engine generator powers to the load by the rectifier in the uninterrupted power supply and inverter, the charge in batteries in the uninterrupted power supply simultaneously.Behind the city power recovery, switch to civil power by diverter switch again and power to the load, disconnect diesel engine generator and uninterrupted power supply.
Use the utility model that safe and reliable electric power supply can be provided.
Can to provide required electric energy to load in order ensureing, among embodiment, to please refer to Fig. 2 therein, also comprise with the emergency power system of diverter switch: the second diesel engine generator and alarm;
Wherein, alarm connects the first diesel engine generator and the second diesel engine generator; The second diesel engine generator is connected with controller.When the diesel engine generator fault was arranged, alarm sends reported to the police and notification controller; Other diesel engine generators of startup generated electricity after controller received alarm signal.
Wherein, the first diesel engine generator and the second diesel engine generator are more than one; Many diesel engine generators can be set respectively according to the actual requirements.
In order further to improve the reliability of electric power supply, in one of them execution mode, uninterrupted power supply adopts on-Line UPS.
Preferably, the utility model adopts on-Line UPS, and its operation principle is: when mains-supplied is normal, civil power through power transformer, rectifier after, the one tunnel exports load to through inverter, filter; Another road through charge circuit to battery charging.Work as commercial power interruption, when the batteries terminal voltage was lower than set point or fault of converter, civil power just powered to the load through change over switch, filter by bypass branch.This shows, no matter civil power is normal or interrupt, on line type UPS (Uninterruptible Power System, uninterrupted power supply) always inverter in work.
The characteristics of on line type UPS:
A. on line type UPS all is sinewave output, and its outstanding feature is the real uninterrupted power supply of having realized load.
B. on line type UPS has been realized the anti-interference power supply to load.Because on line type UPS no matter by civil power or storage battery to load supplying, all to be undertaken by inverter, this just may fundamentally eliminate from all voltage fluctuations on the utility grid and the electrical interference impact on load, and UPS provides the high-quality AC power of a voltage stabilization and frequency stabilization all the time to load.And the sinusoidal distortion factor of on line type UPS is minimum.
C. compare with rear various UPS, when on line type UPS had good temporal properties, it was when 100% load loading or off-load, and the variation of its output voltage is less than 4%, about 10～40ms of time.
D. on line type UPS has higher functional reliability
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
