Abstract
The utility model relates to an equipment used for a low-voltage power supply, distribution and control system, in particular to a direct current combined cabinet. The technical scheme is as follows: the combined cabinet consists of a switch cabinet (1) and a direct current speed regulation control cabinet (6) that are combined together; the switch cabinet comprises an over-voltage protector (2), a circuit breaker (3) and a control transformer (4) that are sequentially connected with one another by copper bars; the direct current speed regulation control cabinet comprises a fully digital direct current speed regulation driver (7), a magnetic field controller (8), a current divider (9) and an output component (10) that are sequentially connected with one another by the copper bars; and the switch cabinet (1) and the direct current speed regulation control cabinet (6) are also connected with each other by the copper bar. The direct current transmission combined cabinet has the beneficial effects of small land-occupying, facilitating installation and maintenance, excellent starting and running characteristics, stepless speed regulation, good stability and reliability, and capability of receiving and sending various control and state signals.
Description
Affiliated technical field:
The utility model relates to a kind of low pressure for distribution and control system equipment, particularly DC Transmission combination sideboard.
Background technology:
At present, because the starting torque of DC motor is big, speed adjusting performance is good, and one time investment cost is less, and the industries such as rotary kiln in cement plant generally adopt direct-current driving device at home.People generally adopt the variable voltage control mode now, promptly change motor speed by the voltage that changes armature, thereby change the kiln rotating speed.Because DC speed regulator has analog control system and numerical control system, the DC speed regulator thyristor needs good heat radiation.But existing dc drive control system floor space is big, is not easy to installation and maintenance, easily causes to start and the operation characteristic instability.
The utility model content:
The utility model purpose provides a kind of DC Transmission combination sideboard, and floor space is little, be convenient to the installation and maintenance stable and reliable operation, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: the DC Transmission combination sideboard is made up of switch cubicle of combining and DC speed regulation control cubicle; switch cubicle comprises overvoltage protector, circuit breaker, control transformer; be linked in sequence successively by copper bar; the DC speed regulation control cubicle comprises total digital DC speed-regulating driver, field controller, shunt, output precision; be linked in sequence successively by copper bar, also connect between switch cabinet and the DC speed regulation control cubicle by copper bar.
Have the heat radiation grid on the combination sideboard, fan is housed at the digital DC speed-regulating driver place of DC speed regulation control cubicle.
Interchange input in the switch cubicle behind the circuit breaker in the switch cubicle, is passed through total digital DC speed-regulating driver, field controller, shunt and output precision in the DC speed regulation control cubicle again, outputs to load at last.
The beneficial effects of the utility model are: floor space is little, be convenient to installation and maintenance; Have good startup and operation characteristic simultaneously, stepless speed regulation, reliable and stable, can accept and send various controls and status signal.
Description of drawings:
Accompanying drawing is the structural representation of the utility model embodiment.
Among the figure: switch cubicle 1, overvoltage protector 2, circuit breaker 3, control transformer 4, copper bar 5, DC speed regulation control cubicle 6, total digital DC speed-regulating driver 7, field controller 8, shunt 9, output precision 10.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
The DC Transmission combination sideboard is made up of switch cubicle of combining 1 and DC speed regulation control cubicle 6; switch cubicle comprises overvoltage protector 2, circuit breaker 3, control transformer 4; be linked in sequence successively by copper bar; the DC speed regulation control cubicle comprises total digital DC speed-regulating driver 7, field controller 8, shunt 9, output precision 10; be linked in sequence successively by copper bar, also connect between switch cabinet and the DC speed regulation control cubicle by copper bar.On the DC Transmission combination sideboard, have the heat radiation grid, fan is housed at digital DC speed-regulating driver 7 places of DC speed regulation control cubicle 6.Interchange input in the switch cubicle 1 behind the circuit breaker 3 in the switch cubicle, is passed through total digital DC speed-regulating driver 7, field controller 8, shunt 9 and output precision 10 in the DC speed regulation control cubicle 6 again, outputs to load at last.
Claims (2)
