Q:What is frequency conversion? What is the function of frequency converter?
Power factor compensation, energy savingThe reactive power will not only increase the heating power loss and equipment, more important is to reduce the power factor of the power grid leads to the decrease of active power, reactive power consumption in a large number of lines, low efficiency, serious waste of equipment, the use of frequency control devices, the inverter internal filter capacitor, thereby reducing the reactive power loss, increase active power grid.
Q:How can I learn the converter well?
Frequency converter this thing, in fact, still very practical, so can go to customers to install and debug, is a shortcut to quickly learn the frequency converter. In the installation of debugging, you can take time to read several times the frequency converter manual, and if you can discuss with technical support, I believe you will soon enter the role.
Q:How does the PLC process the inverter output signal?
Depends on analog or switch volume, if it is analog, you can use analog input module, if it is the amount of switching, with ordinary IO on it
Q:Heating inverter commissioning steps
And carry on the test run 1. manual operation of the frequency converter panel running stop, observe the motor running process and the frequency converter display window, to see if there is abnormal phenomenon. 2. if the P is started and the over-current protection is stopped in the motor, the acceleration P deceleration time should be reset. The acceleration of the motor during acceleration and deceleration depends on the acceleration torque, while the frequency change rate of the inverter during the start and braking is set by the user. If the inertia of motor or motor load change, speed or deceleration rate according to frequency change preset when possible acceleration torque is not enough, resulting in motor stall, motor speed and the inverter output frequency coordination, thus causing overcurrent or overvoltage. Therefore, it is necessary to set acceleration and deceleration time according to the inertia and load of the motor, so that the frequency change rate of the converter can be coordinated with the speed change rate of the motor.
Q:Today, I was asked the question, and I also brought it to you to share the following Oh!
The inverter (power converter, Power Inverter) is a kind of DC12V can be converted to DC and AC220V AC power the same, for general use of electrical appliances, power converter with a convenient car.
Q:What are the key points of frequency converter maintenance?
Frequency converter daily patrolDo the inverter daily inspection and inspection work, inspection contents mainly include: ambient temperature, humidity is required, ventilation windows is good; the inverter air inlet and outlet is blocked by dust or too much dust; inverter operation parameter is normal, there is no alarm; cabinet fan the operation is normal; if there is abnormal sound or vibration transducer; capacitor whether overheat.
Q:Application of ABB frequency converter
When the motor is powered by an industrial frequency power supply, the current increases when the voltage drops; for the inverter, if the voltage drops when the frequency drops, then does the current increase?When the frequency drops (low speed), if the output is the same power, the current increases, but the current remains almost constant under a certain torque.
Q:1, the frequency converter to the motor cable should be shielded cable? 2, whether there are specifications?
1, there are no special specifications, but each oneThe manual must have all the precautions required for good shielding.When the output of high frequency voltage pulse, the higher the frequency, the greater the external radiation interference. UseThe line is mostly blockedExternal interference.2, if there is no other equipment around (usually 5 meters as the boundary), then the shielded line can not be used, because there is no external interference.
Q:What role does input and output reactor play?
The output reactor for the effective transmission distance of extended frequency converter, the instantaneous pressure effectively suppress the IGBT module when switching inverter, reduce noise, reduce the eddy current loss, protection of power switching devices within the inverter.
Q:A control panel I received a photoelectric switch, through the 232 interface connected to the computer, control with a 220V power supply board, computer and inverter when the inverter after the start of the photoelectric switch either do not work or turn off the flash chaos, frequency converter or 232 line open photoelectric switch will be back to normal work. In addition, when the photoelectric switch is powered separately, if the ground wire is connected to the control board, the photoelectric switch does not work. Excuse me, is this interference from the power cord? How to solve?
Isolation of interference: the so-called interference isolation is the separation of the source of interference from the susceptible part from the circuit so that they do not generate electrical contact. Usually in the power supply and controller and transmitter amplifier circuit, in the power line using isolation transformer, so as to avoid conduction interference, power isolation transformer can use noise isolation transformer.
