Technical field
The utility model relates to the electric power project engineering field, particularly relates to a kind of electric power system for sensitive equipment.
Background technology
Along with the high development of the large size city tertiary industry, manufacturing industry is also changed towards the accurate manufacturing mode of high-tech added value.Increasing user, such as physical culture/performance venue, data center, accurate manufacturing and processing industry etc. all had higher requirement to power supply quality.
The supply standard of the sensitive equipment of these industries requires high, its power failure or voltage dip even need to be controlled in the Millisecond, otherwise just may be because the power devices fault causes serious economic loss, special power demands towards these sensitive equipments, existing power supply plan has been difficult to meet the demands, and how sensitive equipment being carried out stable power supply is the new problem that power grid enterprises face.
The utility model content
Based on this, be necessary to be difficult to satisfy for existing power supply plan the problem of the special power demands of sensitive equipment, a kind of electric power system for sensitive equipment is provided.
A kind of electric power system for sensitive equipment comprises: be used for the main power supply of normal power supply, be used for the stand-by power supply of stand-by power supply, automatic throw-in equipment of emergency power supply, uninterrupted power supply;
Described main power supply and stand-by power supply connect respectively automatic throw-in equipment of emergency power supply;
Described uninterrupted power supply is connected between described automatic throw-in equipment of emergency power supply and the sensitive equipment.
Therein among embodiment, described stand-by power supply comprises the electric network source that two-way at least is connected with described automatic throw-in equipment of emergency power supply respectively.
Among embodiment, described stand-by power supply comprises electric network source and the emergency plant that is connected with described automatic throw-in equipment of emergency power supply respectively therein.
Among embodiment, described emergency plant comprises diesel engine generator therein.

Description of drawings
Fig. 1 is the electric power system structural representation that is used for sensitive equipment of an embodiment;
Fig. 2 is the stand-by power supply structural representation of an embodiment;
Fig. 3 is the stand-by power supply structural representation of an embodiment.
Embodiment
Be described in detail below in conjunction with the embodiment of accompanying drawing to the electric power system for sensitive equipment of the present utility model.
Fig. 1 shows the electric power system that is used for sensitive equipment of an embodiment, comprising: be used for the main power supply of normal power supply, be used for the stand-by power supply of stand-by power supply, automatic throw-in equipment of emergency power supply (BZT), uninterrupted power supply (ups) Unity;
Wherein, main power supply and stand-by power supply connect respectively automatic throw-in equipment of emergency power supply; Uninterrupted power supply is connected between automatic throw-in equipment of emergency power supply and the sensitive equipment.
Its operation principle is:
In the normal power supply process, main power supply provides sensitive equipment required electric energy, when main power supply occurs unexpected and can't normal power supply when (as interrupting or voltage dip etc.), automatic throw-in equipment of emergency power supply detects main power supply switch no current, in setting time, the circuit of stand-by power supply has voltage, then automatic throw-in equipment of emergency power supply starts tripping operation order, the switch of tripping main power supply, the switch of the stand-by power supply that closes, use stand-by power supply to power, reach continuous power supply.But there is long switching time (be generally 2-3 second), be unaffordable for sensitive equipment this switching time, within this switching time, uninterrupted power supply detects automatic throw-in equipment of emergency power supply and Non voltage output, startup self energy-storage units is powered fast, owing to adopting power electric component, its reaction time is guaranteed, can satisfy the requirement of sensitive equipment fully, the blank gap of power supply of having filled up the switching time of automatic throw-in equipment of emergency power supply, after automatic throw-in equipment of emergency power supply is finished switching, come sensitive equipment is powered by stand-by power supply.
The automatic throw-in equipment of emergency power supply wiring is simple, and cost is low, success rate is high, can extensively be used in electric power system, but generally have the 2-3 switching time of second.
Uninterrupted power supply is owing to adopting power electric component, reaction time is short, can keep rapidly the uninterrupted power supply of a period of time when having a power failure by energy storage device, but because energy storage is limited, can not be oversize so keep the time of power supply, generally be tens minutes to dozens of minutes.
The technical solution of the utility model takes full advantage of the advantage of automatic throw-in equipment of emergency power supply and uninterrupted power supply, utilizes both advantages and weakness to carry out complementation, thereby can satisfy the required special power reguirements of sensitive equipment.
In one embodiment, as shown in Figure 2, stand-by power supply comprises the electric network source that two-way at least is connected with described automatic throw-in equipment of emergency power supply respectively; By the multichannel stand-by power supply, can improve the fail safe of stand-by power supply.
In one embodiment, as shown in Figure 3, stand-by power supply comprises electric network source and the emergency plant (such as diesel engine generator) that is connected with automatic throw-in equipment of emergency power supply respectively.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
