Description
Technical field
The present invention relates to a kind of power-supply system, relate in particular to and a kind ofly break down suddenly and the emergency power system (EPS) that has a power failure and in time to power in electric power system.
Background technology
Along with social informatization and development of modernization, higher demand is proposed power supply reliability.And power supply department is managed strictly again, and electrical network facilities is advanced again, and the outage phenomenon is also unavoidable, so power failure is sudden strong, is not transfer with people's will often.If electric power system breaks down suddenly and has a power failure, then can destroy the normal living environment of people, bring economic loss to enterprise.Therefore, emergency power system occupies critical role in electrical design.
The supply district of emergency power system is generally:
Fire protection equipment, fire pump, Fire lift, anti-smoke removal facility, automatic fire alarm device, emergency lighting, electronic fireproof door etc.;
Equipment electricity consumptions such as security system, communication, aviation obstruction beacon, electroclock;
The central control room of hotel, commerce, JinRong Building and computer management system;
Important politics, economic implications place, the part electric power and the electric consumption on lighting of large and medium-sized electronic computer room.
In the city of high speed development, a large amount of appearance of skyscraper, heavy construction group, intelligent building, people can emergency service when electrical network disconnected (drawing) electricity to fire-fighting and other important motivity facility, but also requires the reliability height, no smoke evacuation, noiselessness, no disaster hidden-trouble, it is little to take up space etc.
Emergency power system generally can be divided into three major types, and the most frequently used emergency power supply is a battery feed at present, and it is divided into UPS and EPS emergency power supply again.
Following table is the difference table of comparisons of EPS and UPS:
| Index | EPS | UPS |
| Economize on electricity | Mains supply just often is in sleep state, power consumption less than 0.1% | Mains supply is just often also worked |
| Noise | When sleep state noiselessness, no mains supply, its noise is less than 55dB | Operating noise is generally 55-65 dB |
| Price | For with 60% of capacity UPS main frame price | On the high side |
| Life-span | Just carry out inversion work when electrical network does not have electricity, main frame is general more than 20 years useful life | As long as start is just worked general 8 years of life-span continuously incessantly |
| Workload-adaptability | Be particularly useful for inductive load and various mixing electric loadings such as motor | Be applicable to capacitive character and resistive load (computer load) |
| The work purpose | Guarantee that emergency service is perfectly safe | Guarantee the uninterrupted and voltage stabilizing of power supply |
As seen from Figure 1: United States Patent (USP) (publication number is U.S.5686768): emergency power system adopts AC/DC transducer, AC adjuster, current impulse oscillator and comparator and uses the battery charge; It has solved when electric power system is broken (drawing) electricity suddenly, automatically switches to the emergency power system output AC.
But also there is following defective in it:
The first, single AC/DC transducer reliability is not high; If damaged and to have caused the capacity of backup storage battery deficiency, influenced charge in batteries, floating charge etc.;
The second, single AC/DC transducer capacity is excessive, and as standby redundancy, user's cost of use is excessive;
The 3rd, single AC/DC transducer, charging and floating current differ tens times, make this transducer in gamut, components and parts are required high; Components and parts do not use the district in the best yet simultaneously;
In addition, use the battery charge; There is not supervising device.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of emergency power system, are intended to address the aforementioned drawbacks.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes that one one end is connected with ac input end, the bypass circuit that the other end is connected with the emergency power supply electric power system, externally during the AC power normal power supply, what load end was accepted is external ac power source, and the externally irregular or decompression interruption of AC power, the energy switching is to the emergency power supply electric power system; The other end of described emergency power supply electric power system is connected with load; Described emergency power supply electric power system comprises: one is connected with ac input end, and the AC/DC transducer that the other end is connected with storage battery when externally AC power has electricity, charges to storage battery; Charging procedure controller with the coupling of AC/DC transducer and transmission monitor can carry out that perseverance is filled, all filled, floating charge to described storage battery, cell patrol and examine and long-term floating charge after in the time of 720 hours force an equalizing charge change floating charge; The other end that one one end is connected with storage battery with exchange the DC/AC inverter that output is connected, in case can after the external ac power source decompression, be reverse into alternating voltage by the accumulator DC pressure; A control switching device that is coupled with DC/AC inverter and transmission monitor, the energy automatic switching is to the DC/AC inverter power supply; The transmission monitor of monitoring and controlling ac input end, bypass circuit, load, AC/DC transducer, DC/AC inverter.
Compared with prior art, the invention has the beneficial effects as follows: adopt that CPU program control perseverance is filled, all filled, floating charge, cell is patrolled and examined, and makes storage battery be in the full capacity state all the time; Can realize that remote monitoring comprises the web-privilege password Web setting and the LED liquid crystal display of system, can be to any inductive or capacity load power supply.
