Technical field
The utility model relates to a kind of DC power-supply system.
Background technology
Carbon brush (Carbon brush) be also brush, as a kind of sliding contact part, in many electric equipments, is widely used.Carbon brush material in product application mainly contains seawater class electrification and rubs and raise graphite, soaks 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, after energising, rotates with rotor; Brush is fixing on stator, and stator is motionless, and brush is also motionless.The general direction that changes realizes by being fixed on epitrochanterian commutator, if but direction is the tangential direction of circle, direction wants time changing to be difficult to realize.
Summary of the invention
There is above-mentioned defect in order to overcome existing DC power-supply system, the utility model provides a kind of carbon brush to be fixed on rotor, and carbon brush rotates, and its track is exactly two large circles, its direction can time changing, thereby realizes the DC power-supply system of the transmission of direct current supply.
The technical solution adopted in the utility model is:
DC power-supply system, comprises stator and rotor, 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; On described positive and negative electrode copper ring, be respectively arranged with the first wire intertwist hole, positive and negative power line is respectively through the first wire intertwist hole on described positive and negative electrode copper ring 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 is connected with the contact of positive and negative electrode copper ring; On described copper ring carbon brush, be 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, reliably contacts with positive and negative electrode copper ring.
Further, be evenly equipped with four the first installing holes in described insulation Circular Plate, described insulation Circular Plate is connected with bolt of lower base by the first installing hole.
Further, on described copper ring carbon brush, be arranged symmetrically with the second installing hole, described insulating square plate is connected with copper ring carbon brush bolt by the second installing hole.
Described DC power-supply system changes into 24V direct current by power supply changeover device by 220V alternating current and exports; 24V direct current is by two fixed copper rings, and the carbon brush of then flowing through, enters rotating part.Then parallel connection is transferred to each small machine.
The beneficial effects of the utility model are embodied in: use the combination of brush and copper ring, solved the problem of the difficult energising of revolving body.In order to protect user's safety, specially done insulation processing simultaneously.
