Abstract
The utility model relates to a power supply device of a cable television, which comprises two power supplies: a power supply A and a power supply B, wherein the power supply A is connected with a passing or isolation circuit, and the power supply B is connected with the passing or isolation circuit. The utility model is favorable for uninterrupted electricity supply of equipment, can improve the use efficiency and the reliability of the equipment, can prolong the service life of the equipment, and can ensure the normal proceeding of the production and the life.
Description
Technical field
The utility model relates to a kind of supply unit of cable TV.
Background technology
The hfc plant equipment of traditional single supply, power supply work long hours and are easy to generate many destabilizing factors (electrical network clutter, temperature humidity, problems such as EMC); For the operate as normal of power supply, the stability of equipment all can be brought harmful effect.
The utility model content
The purpose of this utility model is the shortcoming that overcomes traditional single supply, and a kind of backup battery circuit is provided.
The utility model is achieved in that to be furnished with two power supplys in the equipment on the same stage; Each power supply connecting respectively by or buffer circuit.
During work, these two power supplys can be worked simultaneously, and promptly each power supply provides a part of electric energy for this equipment.Like this, when one of them power supply broke down, another power supply can be born whole power supplies of this equipment automatically.These two power supplys also can alternation, and like this, when one of them power supply broke down, another power supply can be taken over automatically, continued to bear the power supply task of this equipment.
The utility model helps guaranteeing the uninterrupted power supply to equipment, improves efficient, reliability and the useful life of equipment.
Description of drawings
Fig. 1. the overall structure block diagram of one of the utility model execution mode
Among the figure, the 1st, a-power supply, the 2nd, B-source, the 3rd, the direct current of a-power supply passes through and buffer circuit, and the 4th, the logical and buffer circuit of the direct current of B-source.
Embodiment
Below in conjunction with an accompanying drawing narration embodiment of the present utility model---the backup battery device of cable TV
Show that as Fig. 1 present embodiment mainly is made up of two backup batteries: a-power supply and B-source.
This two power source voltage scope is both 90V-265V.But the two alternation.In case when certain working power breaks down, just, switch to the power supply that another treats work, continue power supply so treat the power supply of work by mechanism for automatically switching.The structure of present embodiment and transmission are as described below:
1, AC power is sent into two power supplys in the equipment respectively by socket: a-power supply (1), B-source (2);
2, the direct current of a-power supply and B-source output is sent into (3) and (4) respectively:
(3) be power supply A direct current by and buffer circuit, its effect is to allow the direct current of A pass through, and cuts off influence and the interference of B-source to a-power supply.
(4) be power supply B direct current by and buffer circuit, its effect is to allow the straight source electricity of B pass through, and cuts off influence and the interference of a-power supply to B-source.
Claims (1)
1. new-type backup battery device is characterized in that: contain two power supplys--a-power supply (1) and B-source (2), a-power supply (1) connecting by or buffer circuit (3), B-source (2) connecting by or buffer circuit (4).
