Abstract
The utility model relates to a three-phase emergency power supply, which comprises a frequency converter. A power supply battery is collocated in the frequency converter. By that the frequency converter is provided with a power accumulator, the utility model realizes that an emergent stable and reliable three-phase power supply is arranged at the time of normal power supply. Except that the utility model has the original advantages of low noise, small size, simple maintenance, quick reaction, variable frequency starting, etc., existing in the frequency converter, the utility model also has the advantages of no pollution, good safety, low load matching, small investment, etc.
Description
The utility model belongs to power electronic technology, is specifically related in case of emergency, and when civil power stops, timely drive motors or the three phase emergency power source equipment of electric consumption on lighting is provided.
Before the utility model was made, in fire-fighting, field such as recover, used power three phase emergency power source was from diesel generating set at present.This power supply has the following disadvantages:
1. the equipment operation noise is big, and exhaust, smoke evacuation are serious, contaminated environment;
2. must adopt when equipment is installed fire prevention, shockproof, oil storage, air inlet, smoke evacuation (gas) measure,
Poor stability, dangerous big;
3. long, poor reliability of this device start time, equipment maintenance cost height, equipment and engineering
Overall cost is expensive;
4. the capacity of power-supply device will be higher than more than 3: 1 than generally with the load capacity apolegamy, and increasing is established
Be equipped with investment and operating cost.
And the frequency converter that is widely used at present, can carry out processing such as rectification, frequency conversion, inversion to civil power, can be implemented in load such as dragging motor under the state of normal power supply, it has, and noise is low, volume is little, maintenance is simple, be swift in response, start after gradually frequency conversion can not impact advantages such as being driven motor.But it can not realize working on when normal power supply stopped, and can not be used as power supply and use.
The purpose of this utility model is to provide a kind of and to frequency converter power supply storage battery is set for addressing the above problem, and the three phase emergency power source of regulated power can be provided when mains failure.
For achieving the above object, the utility model is achieved in that a kind of three phase emergency power source, comprises frequency converter; Connect storage battery on the inverter bridge of connection storage battery or above-mentioned frequency converter on the external communication input connection storage battery of this frequency converter or the rectifier bridge of above-mentioned frequency converter.
A kind of improvement of described three phase emergency power source is above-mentioned storage battery parallel charger.
A kind of improvement of described three phase emergency power source is that above-mentioned frequency converter and storage battery are configured in the housing.
Advantage of the present utility model and good effect are to be connected charger with frequency converter or on storage battery with storage battery and to form three phase emergency power source; It is simple in structure, safe and applicable, economic and reliable, easy and simple to handle, and the length of power-on time can be by the capacity decision of battery simultaneously.And mobility is strong, can be transported to field or interim application site supply three-phase electrical source of power with motor vehicles.Especially run into that normal power supply has a power failure suddenly or because emergencies such as fire earthquake or human accident when having a power failure at skyscraper, miscellaneous equipments such as the fire-fighting of these skyscrapers, water pump, elevator and illumination must guarantee to move a period of time, danger more likely occurs otherwise can make troubles to people; Adopt this three phase emergency power source can in Millisecond, realize emergency service.When normal power supply recovers, can change normal power supply automatically over to again.This three phase emergency power source can also be combated a natural disaster equipment such as middle water supply pump, elevator, fire resistance rolling shutter door, illuminating lamp in fire-fighting provides electrical source of power.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a three-dimensional structure diagram of the present utility model;
Fig. 2 is the electrical schematic diagram of the utility model embodiment one;
Fig. 3 is the electrical schematic diagram of the utility model embodiment two;
Fig. 4 is the electrical schematic diagram of the utility model embodiment three.
Embodiment one:
As shown in Figure 1; a kind of three phase emergency power source comprises frequency converter 1, and wherein the frequency converter outer setting has external power source input 3 and power output end 8; the inside of frequency converter is provided with rectifier bridge 4 and inverter bridge 5, and on-off controller 9 also is set between rectifier bridge and inverter bridge usually.With this frequency converter configuration power supply storage battery 2; Form three phase emergency power source.
As shown in Figure 2, any two inputs of the external communication input 3 of frequency converter such as 3A, 3C connect storage battery 2, and this external communication input also connects civil power.While can be with storage battery parallel charger 6 for storage battery is recycled.
Embodiment two:
As Fig. 1, shown in Figure 3, as embodiment one described frequency converter, on the rectifier bridge 4 of frequency converter, connect storage battery 2, just before the on-off controller 9, make output-controlled system device control; Form three phase emergency power source.For this three phase emergency power source convenient transportation, use simply frequency converter and storage battery to be placed in the housing 7, form an integral body.
Embodiment three:
As Fig. 1, shown in Figure 4, as embodiment one described frequency converter, on the inverter bridge 5 of frequency converter, connect storage battery 2, just after the controller, make the uncontrolled device control of output, this storage battery parallel charger 6; Form three phase emergency power source.For this three phase emergency power source convenient transportation, use simply frequency converter and storage battery to be placed in the housing 7, form an integral body.
During use, when normal power supply, alternating current becomes direct current through rectifier bridge, is reverse into through inverter bridge again and exchanges output; If it is standby to charge a battery by charger again when storage battery is provided with charger.When normal power supply stopped, storage battery started automatically, and direct current energy provides three-phase power through after the inversion to the outside; When normal power supply recovers, enter the normal power supply running status automatically.
The main inventive point of this patent is to dispose storage battery on the basis of frequency converter, makes it can be used as power supply and uses; As for these frequency converter input and output is unidirectional or three-phase, unimportant for the utility model; So the no matter input of frequency converter, output are several phases, as long as frequency converter is disposed power supply storage battery all within the protection range of this patent.
Claims (3)
