Abstract
The invention discloses an emergent power source with a compensation function, which is composed of a compensation inverter, an emergent inverter, a galvanic battery (GB), a charger and an alternating current contactor, wherein, the input end of the emergent inverter is provided with the GB; the output end of the emergent inverter is connected with a power grid through the alternating current contactor; the utility power charges the GB through the charger; the GB is connected with the direct current parts of the compensation inverter and the emergent inverter; the contravariant output voltage of the compensation inverter is switched into the utility power through a transformer; the alternating current contactor controls the emergent power source to compensate the voltage of the utility power by means of the compensation inverter when the utility power is undervoltage; and when the power grid is in fault, the emergent inverter inverts the direct current electric energy of the GB into the alternating current electric power to be used as a load power source. The emergent power source of the invention is not only used for ensuring the emergent power supply when the urban power supply is in fault, but also used for compensating the utility power voltage when the utility power is undervoltage; the use ratio of the emergent power source is improved, and simultaneously the power using condition of people is improved.
Description
Technical field
The invention belongs to the Electrical Control Technology field.
Background technology
Development along with society, the building in city trends towards extensive, high stratification development, in order to reduce the heavy economic losses that interruption of power supply causes, in the building's electrical design in a lot of areas, emergency power supply as the stand-by power supply that is independent of outside the electrical network, is applied among the various architectural engineerings.
Because emergency power supply is an ability emergency when urban electricity supply breaks down, the time that urban electricity supply breaks down was compared with normal time, and is comparatively of short duration after all, causes the utilance of emergency power supply low; In the area that power supply capacity lacks, the under-voltage fault of urban electricity supply is the emergency service importance, and still, present emergency service is not based on the under-voltage fault of powering.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of emergency power supply with compensate function is provided, emergency service when not only being used to ensure the urban electricity supply fault, and in the city during under-voltage power supply, the compensation line voltage, ensure the normal output of civil power, improve the utilance of emergency power supply on the one hand; On the other hand, improve people's electricity consumption condition.
Technical solution problem of the present invention adopts following technical scheme:
1, the emergency power supply that has compensate function, it is characterized in that constituting by compensation inverter, emergent inverter, batteries GB, charger and A.C. contactor KM1, KM2, the input of described emergent inverter is batteries GB, and the output of described emergent inverter is connected with electrical network by A.C. contactor KM2; Civil power is batteries GB charging by charger, and batteries GB is connected with the direct current component of compensation inverter and emergent inverter; The inverter output voltage of compensation inverter inserts civil power by transformer; Control described emergency power supply when civil power is under-voltage by A.C. contactor KM1 and KM2, with compensation inverter compensation line voltage; When electric network fault, be that AC energy is as the electric power supply with the direct current energy inversion of batteries GB with emergent inverter.
The present invention is on the basis of emergency power supply structure, by compensation inverter and A.C. contactor are set, operating state by control system control compensation inverter and emergent inverter, by A.C. contactor KM1 and KM2, realize the conversion of compensation power supply and emergency service, compared with the prior art, beneficial effect of the present invention is embodied in:
When 1, the present invention can satisfy grid power blackout, for the needs of emergency service;
2, the present invention is when the civil power normal range (NR), and compensation inverter and emergent inverter do not move, and do not have inversion no-load loss.
3, the present invention is when civil power is under-voltage, and the compensation inverter is devoted oneself to work, and power has only 15%～20% of inversion gross power.
4, the present invention has effectively improved the service efficiency of emergency power plant, increases value-added content of product;
Description of drawings
Fig. 1 is not intended to for structure of the present invention.
Embodiment
Referring to Fig. 1, present embodiment is to be made of compensation inverter, emergent inverter, batteries GB, charger and A.C. contactor KM1, KM2, the input of emergent inverter is batteries GB, and the output of emergent inverter is connected with electrical network by A.C. contactor KM2; Civil power is batteries GB charging by charger, and batteries GB is connected with the direct current component of compensation inverter and emergent inverter; The inverter output voltage of compensation inverter inserts civil power by transformer, for civil power affords redress.Control described emergency power supply when civil power is under-voltage by A.C. contactor KM1 and KM2, with compensation inverter compensation line voltage; When electric network fault, be that AC energy is as the electric power supply with the direct current energy inversion of batteries GB with emergent inverter.
Present embodiment is realized following conversion of operation state by control system control:
At first detection of grid voltage, battery tension after the start, if line voltage is normal, system works under the normal power supply pattern, A.C. contactor KM1 closure, compensation inverter and emergent inverter are not worked, KM2 disconnects, electrical network is powered to AC load.
When electrical network was under-voltage, the compensation inverter was started working, and then system is transferred to the civil power compensating coefficient, and emergent inverter is not worked, and KM2 disconnects.
When electrical network breaks down, system after detecting electric network fault, automatic disconnection KM1, and can change emergent inverter mode immediately over to, the KM2 closure continues powering load, plays the effect of emergency service.
If line voltage is normal, if find that accumulator electric-quantity is discontented, by charger to charge in batteries.
