Description
Technical field
The utility model relates to a kind of Direct Current Distribution Unit.
Background technology
At present, the communication apparatus that is used for DC distribution mostly generally adopts single supply that it is powered, if power supply breaks down, then other connected equipment also can't normally move, and causes the whole system paralysis, can spend the plenty of time and repair also.
Summary of the invention
At the deficiency that prior art exists, the utility model provides a kind of duplicate supply, the Direct Current Distribution Unit of the switchable power supply that breaks down.
For achieving the above object, the utility model provides following technical scheme: a kind of Direct Current Distribution Unit, include power input, the rectifier bridge of power output end and formation power input and power output end conducting, described power input, power output end and rectifier bridge are provided with two groups, include primary power cource and stand-by power supply, described primary power cource includes the primary power cource input, the primary power cource output, the primary power cource rectifier bridge, stand-by power supply includes the stand-by power supply input, stand-by power supply output and stand-by power supply rectifier bridge, described primary power cource output and stand-by power supply output respectively with a plurality of load input terminal conductings, and primary power cource and stand-by power supply are in parallel and simultaneously and the load input terminal conducting.
Be provided with primary power cource and stand-by power supply in this, primary power cource and stand-by power supply series connection, after being provided with like this, can adopt duplicate supply that communication apparatus is powered, the conducting simultaneously of primary power cource and stand-by power supply, because the required electric energy of communication apparatus has qualification, so adopt two power supplys simultaneously the electric energy that its power supply expends to be equated with the electric energy that single supply expends, in addition, when main power source breaks down, stand-by power supply can not be affected, still can power to communication apparatus, when stand-by power supply broke down, primary power cource can not be subjected to the influence of stand-by power supply equally, equally also can keep power supply, play place apparatus outage and influence the effect of work communication apparatus.
The utility model further is set to: described primary power cource input is connected with main link a with rectifier bridge, and by main link b and the conducting of primary power cource output with rectifier bridge, the stand-by power supply input is connected with main link c with rectifier bridge, and by main link b and the conducting of primary power cource output with rectifier bridge, described stand-by power supply input is connected with the link A of standby rectifier bridge, and link B and the conducting of stand-by power supply output by standby rectifier bridge, the primary power cource output is connected with the link C of standby rectifier bridge, and link B and the conducting of stand-by power supply output by standby rectifier bridge, power supply when constituting primary power cource and stand-by power supply to load input terminal, primary power cource and stand-by power supply are isolated mutually simultaneously.
Connected mode in this has guaranteed that primary power cource and stand-by power supply can power to a plurality of load input terminals simultaneously simultaneously, and primary power cource and stand-by power supply are isolated mutually, prevent that any one road power supply from breaking down and have influence on the power supply of another road power supply to load input terminal.
Below in conjunction with accompanying drawing the utility model is further described:
