Power supply unit, charging module unit, voltage dropping silicon chain unit, DC feedback unit, power monitoring unit, monitoring module unit and absolutely
Edge monitoring unit forms.The middle-size and small-size power plant of power system, power station, all kinds of transformer stations are mainly used in, and other are used directly
The user of flow device（Such as petrochemical industry, mine, railway）, instrument, instrument suitable for switch divide-shut brake and secondary circuit, relay
The occasion such as protection and failure illumination.But energy storage is carried out frequently with batteries in existing direct current cabinet, conventional battery is
Lead-acid battery, although lead-acid battery has the advantages of cost is low, the discharge and recharge number of lead-acid battery is less, deep discharge performance
It is poor, there is the defects of memory effect, service life is short, temperature in use also has large effect to battery performance.During use
Need often to be safeguarded.In the case of some happen suddenly, stricter is required to the power supply performance of battery, lead-acid battery without
Method meets the requirement of direct current cabinet.
The content of the invention
The utility model purpose be for it is existing using batteries carry out energy storage direct current cabinet the defects of, there is provided one
Kind takes into account the DC power system of cost and performance.
The utility model to achieve the above object, adopts the following technical scheme that：
A kind of DC power system, including AC power, AC/DC AC-DC converters, DC/DC direct current transducers, storage
Can device and multiple loads；
The AC power is connected with the AC/DC AC-DC converters, exports direct current；
The AC/DC AC-DC converters are connected with DC/DC direct current transducers, carry out the conversion of DC voltage；It is described
AC/DC AC-DC converters are connected with energy storage device, and energy storage device is charged；
The DC/DC direct current transducers are connected with load, for for load supplying；
The energy storage device is connected with the DC/DC direct current transducers, is supplied after the conversion of DC voltage for load
Electricity；
It is characterized in that：The energy storage device includes batteries and ultracapacitor group, batteries and super
Capacitor bank is in parallel, is respectively different load supplyings by the DC/DC direct current transducers.
It is further characterized by：The load includes system, control circuit, combined floodgate motor, illuminator；It is described super
Capacitor bank is respectively system, control circuit, the power supply of combined floodgate motor by the DC/DC direct current transducers.
Further：The AC power includes conventional power supply and stand-by power supply, is switched by a double-circuit communication inlet wire

The AC/DC AC-DC converters are connected with DC/DC direct current transducers, carry out the conversion of DC voltage；It is described
AC/DC AC-DC converters are connected with energy storage device, and energy storage device is charged.
The DC/DC direct current transducers are connected with load, for for load supplying；
The energy storage device includes batteries and ultracapacitor group, and the batteries and ultracapacitor group are simultaneously
Connection, is connected with the DC/DC direct current transducers, into different load supplyings after the changing of DC voltage.
The ultracapacitor group is respectively system, control circuit, combined floodgate motor etc. by the DC/DC direct current transducers
Important load is powered.
The conventional power supply and stand-by power supply of the AC power, cut by a double-circuit communication inlet wire switching device
Change.When conventional power outage, stand-by power supply power supply is switched to.In handoff procedure, ultracapacitor group passes through
DC/DC direct current transducers are respectively the important load continuous power supply such as system, control circuit, combined floodgate motor, are so as to ensure that
The continuity of system work.
