Abstract
The utility model discloses an emergency power supply with compensation function, comprising a compensation inverter, an emergency inverter, a storage battery GB, a charger and an AC contactor, wherein the input end of the emergency inverter is a storage battery set; the output end of the emergency inverter is connected to a power grid by the AC contactor; commercial power charges the storage battery set via the charger; the storage battery set and the compensation inverter are connected to a DC part of the emergency inverter; the inverter output voltage of the compensation inverter is switched in the commercial power by a transformer; the AC contactor controls the emergency power supply to compensate the voltage of commercial power with the compensation inverter when the commercial power is undervoltage; when the power grid is broken down, the emergency inverter inversely varies the DC electric energy of the storage battery set into AC electric energy to be as the power supply of load. The emergency power supply of the utility model is used for supplying power emergently when commercial power is broken down, as well as for compensating the voltage of commercial power when the commercial power is undervoltage; electricity conditions of people are improved while use ratio of emergency power supply is improved.
Description
Technical field
The utility model 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.
The utility model content
The utility model 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.
The utility model technical solution problem adopts following technical scheme:
The utlity model has the emergency power supply of compensate function, be characterized in 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 utility model 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, the utility model beneficial effect is embodied in:
When 1, the utility model can satisfy grid power blackout, for the needs of emergency service;
2, the utility model 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 utility model 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 utility model has effectively improved the service efficiency of emergency power plant, increases value-added content of product;
Description of drawings
Fig. 1 is the utility model structural representation.
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.
