Purpose.
Accompanying drawing explanation
Utilize accompanying drawing that invention is described further, but the embodiment in accompanying drawing do not constitute any limitation of the invention,
For those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain it according to the following drawings
Its accompanying drawing.
Fig. 1 is the overall structure schematic diagram of a kind of emergency power supply of the present invention.
Fig. 2 is EPS and the structural representation of battery system of a kind of emergency power supply of the present invention.
Detailed description of the invention
The invention will be further described with the following Examples.
The emergency power supply of prior art, including charger, inverter and accumulator battery, when civil power is normal, civil power is by side
Road is load supplying, and civil power is battery charging by charger simultaneously, and during city's electrical anomaly, accumulator battery by inverter is
Load supplying.
The emergency power supply of the present embodiment, as in figure 2 it is shown, include EPS (i.e. emergency power system) and accumulator battery,
EPS includes charger and inverter, and the most charged device of civil power and inverter are connected with load, and civil power is also through bypass directly
Being connected with load, accumulator battery is connected to charger and the direct node of inverter, by switch K1, K2, K3 in control circuit
Realizing different working methods with the state of K4, its working method is as follows:
1, during peak times of power consumption, there is a both of which:
A, EPS work in inverter mode: if the electricity that battery management system detects accumulator battery is not less than volume
When determining 60% (safe electricity is for standby) of electricity, then disconnecting switch K3, making civil power is not load supplying, reduces and makes electricity consumption high
The peak phase uses the civil power of high price, disconnects switch K4, and making civil power is not battery charging, reduces and makes peak times of power consumption use high price
Civil power, disconnect switch K1, Guan Bi switch K2, make accumulator battery to load supplying, make full use of the electric energy that accumulator battery stores,
Because this electric energy stored in the electricity charge comparatively cheap low power consumption phase, it is possible to reduce electric cost, work as accumulator battery
Electricity less than specified electric quantity 60% time, stop to load supplying.
B, EPS work in main power mode: if the electricity size that battery management system detects accumulator battery is less than
Specified electric quantity 60% and higher than specified electric quantity 50% time, in order to this part electricity of accumulator is made when main electrical anomaly
With, now can not employ again, so Guan Bi switch K3, allowing civil power is load supplying, Guan Bi switch K4, makes civil power be continuously charging
Device is powered, and to facilitate enabling of charger, disconnects switch K1, Guan Bi switch K2 so that accumulator battery keeps the moment online, in city
Can be powered during electrical anomaly at once, not be the most battery charging.
2, during the low power consumption phase, EPS works in main power mode: if battery management system detects accumulator battery
When electricity is less than the specified electric quantity of accumulator battery, then Guan Bi switch K3, allowing cheap civil power is load supplying, and meanwhile, Guan Bi is opened
Closing K4, and switch K1, (Guan Bi of switch K4, is that to allow civil power be that charger is powered, and the unlatching of charger is whether to open charger
It is additionally to control, unrelated with switch K4), allowing cheap civil power is battery charging, switch K2 Guan Bi so that accumulator battery
Keep the moment online, can be powered when city's electrical anomaly at once.
3, EPS works in inverter mode: if city's electrical anomaly, then disconnects switch K3, bypass is disconnected, make civil power stop
Only to load supplying, meanwhile, disconnection switch K4, make civil power stop battery charging, switch K1 Guan Bi or disconnection all may be used
With, Guan Bi switch K2, EPS enter inverter mode, by accumulator battery through inverter be load supplying.
Pattern is arranged: by monitoring system, fire-fighting emergency power system is carried out pattern and pre-sets, the charging of EPS, electric discharge
Must the most automatically operate with turning bypass, such as EPS operational mode and run being provided that of time
Above pattern arranges and simply gives one example, and can modify according to actual needs in practical operation.
It addition, as it is shown in figure 1, the monitoring system of the present embodiment includes local monitoring system and the remotely monitoring of intercommunication
System, remotely can be monitored by long distance control system, facilitates monitoring personnel to carry out remote monitor.
The present embodiment specifically carries out pattern at local monitoring system to fire-fighting emergency power system and pre-sets.
A kind of charging/discharging thereof of the emergency power supply of the present embodiment, by being battery charging in the low power consumption phase, because of
The electricity charge for the low power consumption phase are relatively cheap, carry out energy storage in the low power consumption phase and can reduce electric cost, in peak times of power consumption
Make accumulator battery discharge and ensure that accumulator battery leaves minimum standby electricity A, minimum standby electricity A and can ensure that when city's electrical anomaly
There are enough electricity supply loads, carry out releasing energy in peak times of power consumption, it is possible to reduce use the high price electricity of peak times of power consumption, permissible
Reduce electric cost, improve the utilization rate of inverter, and then reach to make full use of the purpose of existing resource.
The method some or all of by setting up functional module construction, is controlled computer system by computer program and comes
Completing, these computer program instructions store in a computer-readable storage medium.
Last it should be noted that, above example is only in order to illustrate technical scheme, rather than the present invention is protected
Protecting the restriction of scope, although having made to explain to the present invention with reference to preferred embodiment, those of ordinary skill in the art should
Work as understanding, technical scheme can be modified or equivalent, without deviating from the reality of technical solution of the present invention
Matter and scope.
