Q: Knowledge, principle and operation method of frequency converter.: The three major parts of the working principle of frequency converter:This is how the inverter works, but how does it work? Mainly composed of three components. (1) convert the power frequency power to the rectifier of the DC power: it transforms the power frequency power into the DC power supply. A reversible converter can also be constructed using two sets of transistor converters, which can be regenerated for their reversible power direction. (2) absorption in the converter and inverter voltage generated by the pulsating "flat wave circuit" in the rectifier DC voltage is rectified, ripple voltage with power frequency 6 times, in addition the pulsating current generated by the inverter to the DC voltage fluctuation. (3) the DC power conversion for AC power rectifier with "inverter": instead, the inverter is DC power converter for AC power required frequency, to the time the 6 switch off, you can get 3 phase AC output.

Q: Can the frequency converter 7.5KW take the motor with 11KW?: Inverter 7.5KW can not take 11KW motor, so that may cause overload inverter.Usually, the frequency converter 7.5KW can take about 5KW motors.

Q: 1, the frequency converter to the motor cable should be shielded cable? 2, whether there are specifications?: Do not use shielded cables have several conditions: the first is from the inverter to motor wear long steel pipe laying cable. Second is the frequency converter to the motor cable line routing (cable bridge, cable ditch), there is no analog signal cable or other weak signal cable. Otherwise, from the debug runtime, if the inverter cable cable line motor and analog signal very close, even if the analog signal shielded cable control cable when the motor running is still very obvious interference of analog signals, especially large power 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 differences between the two quadrant and the four quadrant of the inverter?: The four quadrant inverter can not only drag the motor forward and backward, but also convert the kinetic energy of the motor idle time into electrical energy and feed it back to the power grid. Cause the motor to operate in the generator. Often used in some promotional occasions.

Q: Why does harmonic generator produce harmonic? What's his working principle?: The working principle of the inverter is the first AC into DC, because the alternating current is not directly change its frequency, according to the parameter setting of the machine, and then the DC into AC power, and then drag to load.

Q: How to maintain the frequency converter will not damage, or regular maintenance?: Replacement of spare parts is a common maintenance method of general inverter, inverter composed of various components, some parts of the work for a long time after its performance will gradually decrease, aging, which is the main reason of inverter fault, in order to ensure the normal operation of equipment for a long time, the device should be replaced regularly:

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 a power converter be used in a motor with small power? Will it burn the motor?: Can a power converter be used in a motor with low power, depending on your load and what type of converter is it?.If it is only a common fan, water pump or light load operation, then basically no request, you can use, as long as the relevant parameters can be set.

Q: What is the main harmonic produced by a transducer? How about the degree?: The main hazards are:(1) the possibility of resonance in the power grid is increased, thereby causing high overvoltages or overvoltages to cause the risk of accidents.(2) increasing additional losses, efficiency of transmission and electrical equipment, and utilization of equipment.(3) make the electrical equipment (rotating motor, capacitor, transformer, etc.) run abnormally, accelerate the insulation aging, and shorten their service life.
