Description
Technical field
This utility model belongs to transforming plant DC power technique fields, is specifically related to the transforming plant DC power-supply system of capacitor energy storage system.
Background technology
Accumulator DC operation power supply system is to carry out energy storage by accumulator, and when alternating current is normal and commutator is intact, accumulator is for providing supplemental current to impact load；When exchange power failure or rectifier fault, accumulator is for powering to frequent load, accident loads and impact load.Direct current operative power source with accumulator as energy-storage travelling wave tube is widely used, but due to the inconvenience of on-the-spot battery service and to the mistaken ideas in the use of " non-maintaining " accumulator, causes the performance of accumulator, life-span to be substantially reduced.Additionally fault rate also increases because of the multi-section serial of battery, and any batteries is problematic, all will affect the normal work of whole accumulator battery.Chopper needs big electric current in short-term when dividing, closing a floodgate, the problem existed due to the said equipment so that DC operation power supply system reliability is substantially reduced.
Summary of the invention
This utility model purpose is to solve the problem that prior art exists, it is provided that have the transforming plant DC power-supply system of capacitor energy storage system.
This utility model adopts the technical scheme that for solving above-mentioned technical problem:
Having the transforming plant DC power-supply system of capacitor energy storage system, including accumulator DC operating system, described accumulator DC operating system includes closing bus bar, closing coil and closing switch, and wherein closing bus bar includes closing bus bar positive pole and closing bus bar negative pole；It is characterized in: also include that capacitor energy storage system, described capacitor energy storage system include isolating transformer, rectifying and voltage-stabilizing charging module, discharge diode and Capacitor banks；The input of the output termination rectifying and voltage-stabilizing charging module of described isolating transformer, the input of the output termination Capacitor banks of rectifying and voltage-stabilizing charging module；The positive pole output of described Capacitor banks connects closing bus bar positive pole by discharge diode, and the negative pole output of Capacitor banks directly connects closing bus bar negative pole.
This utility model compared with prior art, has the advantages that
Owing to this utility model uses capacitor energy storage system, and capacitor energy storage system safeguards simple, equipment environmental protection, low cost, installation is simple, charge and discharge speed is fast, point, making process provides the power of formed objects with accumulator, share accumulator DC operating system as electric current during independent power supply, make accumulator battery from the impact of big electric current, and increase the service life, substantially increase the reliability of DC power system.
