Description
Technical field
The present invention relates to a kind of DC power-supply system.
Background technology
Carbon brush (Carbonbrush) be also brush, as a kind of slide contact member, is widely used in many electric equipments.Carbon brush material on products application mainly contains seawater class electrification and rubs and raise graphite, leaching fat graphite, metal (cupric, silver) graphite.Carbon brush is the device of transferring energy or signal between the standing part of motor or generator or other rotating machineries and rotating part, it is generally that pure carbon adds coagulating agent and makes, external form is generally square, be stuck on metallic support, there is spring handle the inside, and it is pressed in rotating shaft, when electric machine rotation, electric energy is flowed to coil by phase changer, because its main component is carbon, be called carbon brush, it is easy to wear.
General commutator is fixed on rotor, with rotor turns after energising; Brush is fixing on stator, and stator is motionless, and brush is also motionless.General change direction realizes by being fixed on epitrochanterian commutator, but if direction is the tangential direction of circle, namely direction wants time changing to be then difficult to realize.
Summary of the invention
Above-mentioned defect is there is in order to overcome existing DC power-supply system, the invention provides a kind of carbon brush is fixed on rotor, and namely carbon brush rotates, and its track is exactly two large circles, its direction can time changing, thus realizes the DC power-supply system of the transmission of direct current supply.
The technical solution used in the present invention is:
DC power-supply system, comprises stators and rotators, it is characterized in that: described stator comprises insulation Circular Plate and positive and negative electrode copper ring, and described insulation Circular Plate is connected with bolt of lower base, and described positive and negative electrode copper ring is connected with insulation Circular Plate glue; Described positive and negative electrode copper ring is respectively arranged with the first wire intertwist hole, positive and negative power line is each passed through the first wire intertwist hole on described positive and negative electrode copper ring and fastening by bolt and nut;
Described rotor comprises copper ring carbon brush and insulating square plate, and described insulating square plate is connected with copper ring carbon brush bolt, and described copper ring carbon brush contacts with positive and negative electrode copper ring and connects; Described copper ring carbon brush is provided with the second wire intertwist hole, the second described wire intertwist hole is connected with output electric wire.
Further, described copper ring carbon brush is U-shaped structure, with positive and negative electrode copper ring reliable contacts.
Further, described insulation Circular Plate is evenly equipped with four the first installing holes, described insulation Circular Plate is connected with bolt of lower base by the first installing hole.
Further, described copper ring carbon brush has been arranged symmetrically with the second installing hole, described insulating square plate is connected with copper ring carbon brush bolt by the second installing hole.
220V AC conversion becomes 24V direct current to export by power supply changeover device by described DC power-supply system; 24V direct current, by two fixed copper rings, then flows through carbon brush, enters rotating part.Then parallel connection is transferred to each small machine.
Beneficial effect of the present invention is embodied in: the combination using brush and copper ring, solves the problem of revolving body difficulty energising.Simultaneously in order to protect the safety of user, specially do insulation processing.
