- Q: Why does the frequency converter cause interference?
- Reasonable wiring: the concrete method has:The power line and signal line of the equipment shall be as far as possible from the input and output lines of the converter.Other equipment power lines and signal lines should be avoided parallel with the input and output lines of the inverter.If the above measures are not successful, then continue the following measures:
- Q: Knowledge, principle and operation method of frequency converter.
- The history of the principle of frequency converter:Frequency conversion technology is born with the need of AC motor stepless speed regulation. After 1960s, the power electronic devices through SCR (SCR), GTO (gate turn off thyristor (BJT), bipolar power transistor), MOSFET (metal oxide semiconductor field effect transistor), SIT (static induction transistor), SITH (static induction thyristor (MGT), MOS control MCT (MOS) transistor, thyristor controlled), IGBT (insulated gate bipolar transistor), HVIGBT (high voltage insulated gate bipolar transistor) device to update the development process, to promote the continuous development of power electronics technology (note that because of this, so the inverter is in this background). The beginning of 1970s, PWM VVVF (PWMVVVF) control has aroused great attention. In 1980s, PWM mode optimization, as the core of frequency conversion technology, attracted people's interest and obtained many optimization models, among which the saddle wave PWM model was the best. Since the latter half of the 1980s, the VVVF inverters in developed countries such as the United States, Japan, Germany, Britain and other developed countries have already been put into the market and have been widely used. As to understand the principles of various types of frequency converter, you might as well look at the four changes in the frequency control mode from the simple to the complex.
- Q: Which country invented the inverter?
- The frequency converter is not developed by a certain individual, it is the research result of a large number of scientific research workers.The background of inverter technology is the wide demand of AC motor stepless speed regulation. The traditional DC speed regulation technology is limited because of its large size and high failure rate.
- Q: The frequency converter is in use suddenly the speed reduces, then the debugging is out of control, how to do?
- The average DC voltage Ud=1.35U line =513V is calculated by the 380V line voltage. When the overvoltage occurs, the energy storage capacitor on the DC bus will be charged, and when the voltage rises to about 700V, due to different models, the converter will protect the voltage. There are two main causes of over voltage: over voltage and over voltage.
- Q: It was when processing a workpiece, processing spindle stops suddenly (other are normal) a check is, I jump out of the inverter, I can click on a processing, and then processing not long after they happen, (do not open the machine spindle machining will also be the case)
- Suggest you in the inverter power installed a frequency converter input filter, try it, feel a bit like electromagnetic interference caused by frequency converter mistakenly stop ah.
- Q: What is a frequency converter?
- VVVF: change voltage, change frequency CVCF: constant voltage, constant frequency. AC power supplies used in various countries, whether for homes or factories, have voltages and frequencies of 400V/50Hz or 200V/60Hz (50Hz), and so on. Normally, a device that changes the alternating current of voltage and frequency to a voltage or frequency variable alternating current is called a frequency converter". To produce a variable voltage and frequency, the device first transforms the alternating current of the power source into direct current (DC).
- Q: The difference between soft starter and converter
- The soft starter is during the start-up of the equipment to take blood pressure or other ways to reduce the starting current of the inverter machine, the device is in operation according to the equipment load by changing the size of the power frequency and regulating equipment output.
- Q: PT100 temperature patrol instrument, when the converter is not open, the measurement is normal. Once opened, it shows completely disorder, and sometimes there are puzzling characters. How can I solve this problem? Please enlighten master!
- In your description of the problem, the patrol instrument shows that there has been a disturbance, then it shows that the patrol meter itself has been greatly disturbed and the work is out of order! If you can't add these two options, you can only change the test scenario.
- Q: Can 220V use frequency converter to drive three-phase motor with 380V?
- If it is a star connection instead of a three phase 220V AC input, will the efficiency of the motor be reduced? Can you achieve the efficiency of the original motor 380V?
- Q: How to choose frequency converter?
- 1. the power of the inverter is selected according to the load power. How many power motors should be chosen for a multi power motor?. Size one is ok.2. frequency converter model, different uses, choose different frequency converter. For example, there are general frequency converter, fan, water pump dedicated inverter, a machine tool spindle dedicated inverter. Wait。
