Abstract

The utility model belongs to an uninterrupted power supply (electric power storage (EPS) series), which is mainly applied to the fields of fire fighting, high-rise buildings, financial system devices, military radars, hospitals and operating rooms, stadiums and the like. An emergency lighting EPS mainly adopts a single phase, and mainly supplies centralized power supply to emergency lighting occasions (marketplaces, entertainment places, office places, trading places and the like). When input power supply is normal, one branch of a mains supply is output for daily lighting through a conversion device, the other branch of the mains supply charges a battery pack through a charger; and when a controller detects break-off or anomaly (on the low side or on the high side) of the mains supply, the controller sends starting signals to an inverter, and controls a mutual throwing conversion device to be converted into inverter output. Of course, the EPS can be used as a two-branch power supply and a three-branch power supply according to different connection methods of the EPS.

A kind of uninterrupted power supply

Technical field

The utility model relates to a kind of uninterrupted power supply, especially is applied in fields such as fire-fighting, skyscraper, financial sector equipment, military radar, hospital and operating room, stadiums.

Background technology

At present, mostly the uninterrupted power supply that at home and abroad uses is UPS, and in American-European advanced country, because the power supply of being incorporated into the power networks, electric power is sufficient, and power supply quality is good simultaneously, adds the power consumption equipment standard, can on electrical network, not cause electric network pollution, phase mutual interference.Therefore, many occasions do not advise using two inversion on line type UPSs, and on line type UPS only has one tunnel output, generally stress its three big function: (1) voltage stabilization and frequency stabilization; (2) to the high uninterrupted power supply of demand switching time; (3) purify civil power, two translation circuits of daily Chong Zhengliu inversion are supplied power, and just convert bypass power supply when fault of converter or overburden into, and utilization rate of electrical is not low.

Summary of the invention

To the shortcoming that above-mentioned prior art exists, the experience of this area work is engaged in inventor's accumulation for many years, through feasibility study repeatedly, gets the generation of the utility model eventually, and the utility model provides a kind of uninterrupted power supply.

The technical scheme that the utility model adopts is: a kind of uninterrupted power supply, emergency lighting type EPS generally with single-phase be main, be mainly emergency lighting occasion (market, public place of entertainment, office space, transaction place etc.) centrally connected power supply be provided.When importing power supply just often; Civil power is leaded up to conversion equipment and is exported to normal lighting, and batteries charging is given through charger in another road, when controller detects that civil power interrupts or when unusual (on the low side or higher); Send enabling signal to inverter, and the mutual conversion equipment of throwing of control goes to inverter output.Certainly, for the method that the connects difference of EPS, can also be used as two road power supplys, three-way power use to EPS.When civil power, civil power is through km1 output, and charger is to battery charge simultaneously, crosses when low when EPS detects mains failure or line voltage, and inverter work makes KM1 switch to emergent output state and to load electric energy is provided.The input of one road civil power two-wire, load by external switch control, can be opened and can close at ordinary times.But cross when low when EPS detects mains failure or line voltage, no matter K switch is in any position, all can realize emergency service.Under normal circumstances, civil power is through KM1, KM2 output, and charger charges to maintenance free cell simultaneously, works as mains failure; Subsequent use electricity drops into through KM3, KM1 output, has only when electricity commonly used and subsequent use electricity have a power failure simultaneously, makes KM1 switch to emergent output state through the work of controller control inverter; To load power supply is provided, but when subsequent use electric making time greater than this EPS switching time, this EPS drops into earlier; When coming etc. subsequent use electricity, switch and withdraw from, the mutual throwing device of this kind mode is in this EPS.Adopt this kind mode of connection can realize the terminal throwing mutually of a stage load, EPS serves as the Third Road power supply, and this kind mode is thrown device mutually outside this EPS.

This uses novel a kind of uninterrupted power supply major advantage to be: when civil power has electricity, be in wait state, noiselessness 1.; During no civil power, inverter work, noise need not discharged fume less than 60bB, shockproof processing, and have characteristics such as nuisanceless, no disaster hidden-trouble.

2. automatically switch, mains-supplied and EPS power supply are supplied power and are 0.1～0.25s mutual switching time, and high terminal can be realized unattended operation, online monitoring;

3. load capacity is strong, and EPS is adapted to the Combination load equipment, like elevator, water pump, blower fan, emergency lighting etc.Use reliable, the general main frame life-span to reach more than 20 years;

4. adaptation adverse circumstances can be positioned over basement or switchgear house, even in the architectural shaft, can be close to emergent load field of employment and be provided with on the spot, reduce supply line, accomplish the most terminal the switching;

5. for the bigger electricity consumption facility of some power; Can directly link to each other like fire pump, blower fan, EPS and to make dynamic Control type emergency power supply with motor; Can save the settings such as soft start and control cabinet of motor, can select most economical power factor for use simultaneously, thereby embody better economic property.

6. emergency power time: standard type is illumination: 90min, power: 120min; The time-delay interface is arranged, changeable.

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
