Q:What's the frequency converter for? What does it look like?
AC motor stepless speed regulation can save energy in some occasionsThe appearance of the basic manufacturers are one of the same
Q:What is the difference between inverters and inverters?!!
The frequency converter is the electric energy control device that transforms the power frequency power to another frequency by the on-off function of the power semiconductor device. We now use the converter mainly adopts the AC-DC-AC mode (VVVF inverter or variable frequency vector control), the first AC power into DC power supply through the rectifier, then the AC power into DC power supply frequency and voltage can be controlled by the supply of electric motive. The frequency converter circuit is usually composed of rectifier, intermediate DC link, inverter and control of 4 parts. The rectifier is a three-phase bridge controlled rectifier, and the inverter is IGBT three-phase bridge inverter, and the output is PWM waveform. The intermediate DC link is filter, DC energy storage and buffer reactive power.
Q:What is the TTK converter produced?
Mainly engaged in TTK brand inverter products R & D, manufacturing, SMT surface mount OEM processing, and agents of well-known brands at home and abroad, frequency converters and electronic components. The agent of many brands, manufacturers become the primary agent, after ten years of unremitting efforts, has formed the electronic components supply system, to meet the basic needs of all customers required inverter suction electronic components. Due to the rapid delivery, excellent reputation, has a large number of customers in East China. Now the Shanghai Volkswagen Schneider, L.D., and many domestic large enterprises supporting inverter and electronic components products supply, for many years by the number of units as the best supplier.
Q:Can 220V use frequency converter to drive three-phase motor with 380V?
Can not. The inverter is not step-up, single-phase 220V AC frequency converter into it is three-phase 220V AC motor is connected if your star angle connection can be changed, if the corner there's no way, after the motor power will be reduced about 4/10.
Q:Hello everyone, I was doing fine tuning, ask inverter carved machine always ranging from the time jump out ah?
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 the upper and lower limit of the environmental temperature to ensure the normal operation of the inverter?
Ambient temperature. When the temperature of converter is too high and the temperature changes greatly, the inner of converter is prone to dew. The insulation performance will be greatly reduced, and even short-circuit accident may occur. If necessary, a desiccant and heater must be added to the case.(3) corrosive gases. The use of the environment, if the corrosive gas concentration is large, not only will corrode the components of the lead, printed circuit boards, etc., but also accelerate the aging of plastic devices, reduce insulationIn this case, the control box shall be made into a closed structure and ventilated.
Q:What is the difference between a converter and a transformer in Yu Na?
The main function is to change the power supply voltage transformer, but also has some other functions, such as isolation transformer, is to play a protective role, he doesn't play the role of the transformer, the transformer that you are, in what place, or auto? Is it installed in the distribution panel? If you say is likely to auto start with the inverter itself is changing the power supply of the power frequency, when the electric motor is often used in some special occasions will be used! Because the most convenient way to change the speed of the motor is to change the frequency of the power supply!
Q:How to check the frequency converter is there a problem?
Once the inverter has hardware faults, such as rectifier, inverter circuit and so on. The IGBT module may be damaged, and most of the time it will damage the drive components. The most easily damaged devices are the regulator and the optocoupler. Conversely, components such as capacitance, leakage, breakdown, and optocoupler aging can also cause IGBT modules to burn out or frequency conversion, and output voltage is unbalanced. Check if there is a problem with the drive circuit, and compare the resistance of the trigger terminals when the circuit is not switched on. The voltage waveform at the trigger end can be measured when the power is switched on. However, some inverters are not equipped with modules and can not switch on, when the module P end of the series into a false load, to prevent detection, mistakenly touch the originator or other circuit burned module. In this case, the frequency converter has been seriously damaged (by measuring whether the input and output are short circuited), then there should be special technical personnel maintenance, and generally may not re energized, so as not to expand the scope of failure.
Q:What does the RUN key on the inverter mean? How do you use it?
There are two conditions on the panel of the converter. There is one panel with FWD (positive turn), REV (reverse), and STOP (stop). There is also a panel, only the positive turn, just write RUN.
Q:What are the differences between electronic governor and frequency converter in motor speed regulation?
The electronic governor for single-phase motor, by changing the access winding resistance and capacitance to adjust the motor speed, the speed of the output power supply for power has not changed, so the speed is not a kind of energy-saving control methods, such as the electric fan like for home.
