Abstract
The utility model relates to a motor, in particular to a yaw integrated motor with a frequency converter, which comprises the frequency converter and an asynchronous motor. The frequency converter is arranged on a top casing of the asynchronous motor, a ventilation port is arranged in the rear of the top casing of the asynchronous motor, and the rear of the frequency converter is arranged above the ventilation port. The yaw integrated motor has the advantages that the ventilation port is arranged between the frequency converter and the motor, and a clearance between the frequency converter and the motor can be better utilized for dissipating heat for the motor and also carrying out forced cooling air radiation for the frequency converter, which contributes a lot to solve troubles caused by temperature to motor performance when the temperature inside a cabin of a running wind turbine is very high.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of driftage integrated electric machine with frequency converter.
Background technology
General large-scale grid type wind-driven generator adopts the active yawing system mostly, the drive motor of promptly going off course, by transmission mechanism impeller and cabin are rotated a certain angle jointly around the axial line of pylon, realize that impeller remains the aligning wind direction, so that absorb more wind energy.But, in the wind direction frequent variations or when untying the mooring rope, just need driftage motor frequent starting, quit work, if there is not suitable protection will certainly cause damage, thereby increase maintenance cost, reduce the life-span to motor.In the past the Yawing mechanism of wind-driven generator by: driftage power source, driftage transmission device, driftage actuator, driftage bearing and brake apparatus are formed.The driftage power source is provided by yaw motor.So, when impeller location and wind direction departed from, controller received the signal that anemoclinograph sends, and discharged the hydraulic pressure clamp, start the driftage motor, rotate in the cabin, arrives consistent with wind direction up to the cabin, driftage adjustment is finished, the braking of hydraulic braking clamp, location, cabin.
The utility model content
Provide a kind of driftage integrated electric machine with frequency converter for solving the problems of the technologies described above the utility model, purpose is by increasing frequency converter realize going off course soft start, the soft stop of motor; Through the inverter control motor forward and backward, the damage that also will reduce Fraquent start simultaneously and stop motor circuit is caused really realizes the safe and reliable operation of driftage motor better, realizes the ventilation to motor, again frequency converter is dispelled the heat.
For reaching the driftage integrated electric machine of above-mentioned purpose the utility model band frequency converter, comprise frequency converter and asynchronous motor, frequency converter is located on the top enclosure of asynchronous motor, is provided with ventilating opening at the rear portion of the top enclosure of asynchronous motor, and the rear portion of frequency converter is located at the top of ventilating opening.
Described frequency converter is by on the casing that is bolted to asynchronous motor.
The both sides of described frequency converter are respectively equipped with frequency converter and connect Electric Machine Control line outlet and frequency converter and connect the master control line and export.
The utility model has the advantages of: adopt a threephase asynchronous that has frequency converter, frequency converter is fixed on the motor casing, not only reached the control requirement and need but also save space in the limited cabin.Link to each other with control line between frequency converter and the motor, and the control line that comes out of frequency converter one side is connected on the plug under the mainframe of cabin, again signal passed to master controller.So, when impeller location and wind direction departed from, controller received the signal that anemoclinograph sends, discharge the hydraulic pressure clamp, will start the work of driftage motor by frequency converter, when the cabin turns to consistent with wind direction, driftage adjustment is finished, the braking of hydraulic braking clamp, location, cabin.Realized soft start, soft stop, reduced the impact that Fraquent start causes motor greatly yaw motor.Between this external frequency converter and the motor ventilating opening is set, the gap between good utilisation frequency converter and the motor more, can be to the motor self-radiating, can force cold wind heat radiation to frequency converter again, this plays great role to alleviating temperature to the inconvenience that motor performance causes when temperature is very high in the cabin of running wind-driven generator.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the end view of Fig. 1.
Among the figure: 1, asynchronous motor; 2, frequency converter; 3, bolt; 4, ventilation hole; 5, frequency converter connects the outlet of Electric Machine Control line; 6, frequency converter connects the outlet of master control line.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The driftage integrated electric machine of the utility model band frequency converter as shown in the figure, comprise frequency converter 2 and asynchronous motor 1, frequency converter 2 is located on the top enclosure of asynchronous motor 1, rear portion in the top enclosure of asynchronous motor 1 is provided with ventilating opening 4, the rear portion of frequency converter 2 is located at the top of ventilating opening 4, frequency converter 2 is fixed on by bolt 3 on the casing of asynchronous motor 1, and the both sides of frequency converter 2 are respectively equipped with that frequency converter connects Electric Machine Control line outlet 5 and frequency converter connects master control line outlet 6.
When change of the wind, frequency converter receives the control command that master controller sends, thereby again by the rotation of the control line drive motors between frequency converter and motor driven gear case, drives the cabin again and rotate.Be to reach rated speed gradually when the motor of Frequency Converter Control has just begun to rotate with " slope " form, the impact of the rated speed that directly is added to when alleviating no frequency converter.When reaching the driftage preset value, the driftage one motor of band frequency converter can reduce rotating speed gradually to stopping, and really realizes the purpose of soft start, soft stop.And, can also realize protection to motor circuit, ensure its safe and reliable operation.Ventilating opening is located between frequency converter and the asynchronous motor among Fig. 1 and Fig. 2, and, facing the part of the heating circuit in the frequency converter, can also dispel the heat to frequency converter when forced heat radiation is carried out in the electric motor fan rotation like this.
And, because the selection of vent position is just right, make motor when air discharging and radiating is forced in operation, can also dispel the heat during machine operation to frequency converter, effect is remarkable.
