Power supply.
Background technology
With the development of society, the distribution of building is more and more abundant, meets an urgent need and match electricity demanding also increasingly diversification.Same
The a variety of power supply modes of emergent distribution in one building appear in our life.Emergency power supply is supported on continuous generation
Variation, some are supported on alternating current and use under normal circumstances and have a power failure and do not use, such as most of normal lightings, office load；Have
It is not used a bit in normal condition, but used after alternating current power-off, such as fire-fighting emergency headlamp；Some be no matter alternating current whether just
Often work, load all to be used, such as fire-fighting emergent identification lamp.Therefore it can be that these emergent distribution carry to need emergency power supply
For a variety of power supply modes, but the effect of currently used emergency power supply still rests on after power failure and carries out emergency service for load
To ensure the operation of important load, the state of such a simple modes of operation.Do not have the ability of above-mentioned a variety of power supply modes,
The emergency power supply having a single function cannot be satisfied the demand of diversification power supply mode.
Invention content
A kind of emergency power supply with a variety of power supply modes provided by the invention, solve the emergency power supply that has a single function without
Method meets the problem of diversification power demands.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of emergency power supply with a variety of power supply modes, it is characterised in that：Including input circuit breaker Q FA, charger
LKC, accumulator GB, inverter UI, first contactor KM1, second contactor KM2, the first output circuit breaker Q F1, the second output
Circuit breaker Q F2, third output circuit breaker Q F3；
The one end of the input circuit breaker Q FA respectively with the first input circuit breaker Q F1 and first contactor KM1 connects
It connects, the other end of the first contactor KM1 is connect with the second output circuit breaker Q F2, the input circuit breaker Q FA and institute
The input terminal connection for stating charger LKC, between the output end of the charger LKC and the accumulator GB and the inverter UI
Node connection, the inverter UI respectively with the third export circuit breaker Q F3 and second contactor KM2 one end connect,
The other end of the second contactor KM2 is connect with the second output circuit breaker Q F2.
Further, emergency power supply provides corresponding power supply mode for three kinds of different loads, the first is only in city
The load just to work when electric normal is for second the load of non-stop run, the third is the load under standby mode of operation.
Further, the first contactor KM1 and second contactor KM2 is interlocked relationship.
Further, when the first contactor KM1 is closed, only in alternating current normally and under non-stop run state
Load has output, the load of standby mode of operation not to export, when the second contactor KM2 is closed, only non-stop run
Load with emergency has output, and the load of normal alternating current work is without output.
Further, under alternating current normal operation, first contactor KM1 is attracted, and second contactor KM2 is disconnected, the
One output circuit breaker Q F1 and the second output circuit breaker Q F2 closures have output, and inverter UI does not work at this time, therefore third exports
Circuit breaker Q F3 is not exported；In utility power failure, second contactor KM2 is attracted, and first contactor KM1 is disconnected, inverter
UI starts to work, and the direct current in accumulator is reverse into alternating current, the second output circuit breaker Q F2 and third output through inverter UI
Breaking QF3 closures have output, the first output circuit breaker Q F1 not to export.
Beneficial effects of the present invention：The present invention realizes a variety of suppliers of electricity of emergency power supply by two interlocking contactors
Formula has the characteristics that circuit is simple, at low cost, can not only meet the power demands of different loads, and the failure encountered is more
Less, performance is more stable.
Description of the drawings
In order to facilitate the understanding of those skilled in the art, the present invention will be further described below with reference to the drawings.
Fig. 1 is a kind of emergency power supply connection diagram with a variety of power supply modes of the present invention.
Specific implementation mode
A kind of emergency power supply with a variety of power supply modes, including input circuit breaker Q FA, charger LKCCK, accumulator
GB, inverter UI, first contactor KM1, second contactor KM2, the first output circuit breaker Q F1, the second output circuit breaker Q F2,
Third exports circuit breaker Q F3；
Input circuit breaker Q FA is connect with one end of the first output circuit breaker Q F1 and first contactor KM1 respectively, and first connects
The other end of tentaculum KM1 is connect with the second output circuit breaker Q F2, and input circuit breaker Q FA is connect with the input terminal of charger LKC,
Node connection between the output end and accumulator GB and inverter UI of charger LKC, inverter UI are disconnected with third output respectively
Road device QF3 is connected with one end of second contactor KM2, and the other end of second contactor KM2 and the second output circuit breaker Q F2 connect
It connects.
Under alternating current normal operation, alternating current AC enters emergency power system by inputting circuit breaker Q FA, and at this time first
Contactor KM1 is attracted, and second contactor KM2 is disconnected, and wherein first contactor KM1 and second contactor KM2 is interlocked relationship, the
One output circuit breaker Q F1 and the second output circuit breaker Q F2 closures have output, while charger LKC is that accumulator GB charges,
Since inverter UI does not work under normal circumstances, third output circuit breaker Q F3 is not exported.
In utility power failure, second contactor KM2 is attracted, and first contactor KM1 is disconnected, at this point, inverter UI is opened
Beginning work, the direct current in accumulator are reverse into alternating current, the second output circuit breaker Q F2 and third output open circuit through inverter UI
QF3 closures have output, the first output circuit breaker Q F1 not to export.
Emergency power supply provides corresponding power supply mode for three kinds of different loads, the first be only when alternating current is normal
The load of work is for second the load of non-stop run, the third is the load under standby mode of operation.
First output circuit breaker Q F1 only just has output when there is alternating current normal, and no matter alternating current is the second output circuit breaker Q F2
No normal work has output, third input circuit breaker Q F3 only just to have output in utility power failure.
It is interlocked relationship that alternating current, which bypasses the first contactor KM1 of output end and the second contactor KM2 of inverting output terminal, when
One of contactor is closed, another contactor disconnects, when first contactor KM1 is closed, only alternating current normally and not
Load under intermittent duty has output, the load of standby mode of operation not to export, when second contactor KM2 is closed, only
There are non-stop run and the load of emergency to have output, and the load of normal alternating current work is without output.
The above content is just an example and description of the concept of the present invention, affiliated those skilled in the art
It makes various modifications or additions to the described embodiments or substitutes by a similar method, without departing from invention
Design or beyond the scope defined by this claim, be within the scope of protection of the invention.
