- Q: High-voltage converterGeneral inverterPump frequency converterEngineering frequency converterCould you tell me some frequency converter according to the class?
- According to the classification of link Transformation: (1) the AC-DC-AC converter is the first AC into DC rectifier through, and then transformed into the frequency DC voltage adjustable AC inverter, also known as indirect, is currently widely used general-purpose inverter. (2) can be divided into cycloconverter, is directly converted into AC voltage adjustable frequency AC, also known as direct inverter DC power supply according to the classification of properties: (1) the voltage type inverter voltage type inverter is characteristic of DC link energy storage device using a large capacitor load reactive power will be it is to buffer the DC voltage, DC power supply is relatively stable, smaller internal resistance and the equivalent voltage source, so that the voltage type inverter, are often used for load voltage changes in the larger situation. (2) current inverter current type inverter is characterized by large DC link inductance as a storage buffer of reactive power, which changes the current control, the voltage is close to sine wave, because the DC resistance is large, so that the current source converter (current). The characteristics of current source inverter (advantages) can restrain the load current is frequent and rapid changes.
- Q: What's the function of this brake unit?
- The normal asynchronous motor in power loss, but also because of the inertia and load rotor rotate continuously for a period of time, at this time, due to the current of the rotor motor will still exist, such as the generator, sent to the power supply current. When a short circuit fault occurs, the motor also provides feedback current.
- Q: Why do you install these things? Our factory has 380220 points. Then we plant in addition to high voltage motor, the other are 380 of the motor, then what's the use of these two things?
- Asynchronous motor is the torque between the current flowing through the motor flux and rotor as a result of the interaction, at rated frequency, but only if the voltage will reduce the frequency, then the magnetic flux on a large magnetic circuit saturation, the motor will be seriously burned. Therefore, the frequency and voltage should be changed proportionally, that is to say, to change the frequency, to control the output voltage of the converter at the same time, to keep the flux of the motor to be certain, and to avoid the occurrence of the weakening of the magnetic flux and the saturation of the magnetic flux. This control mode is mostly used in fans, pumps and energy saving inverters. The frequency changer changes the voltage, must change the frequency
- Q: Where is the frequency converter used?
- The machinery manufacturing industry, including: elevator, automobile, textile, printing and packaging, paper making, hoisting machinery, food, tobacco, etc. the use of these pumps, inverter industry is mainly in electrical equipment, control and obtain the best product performance and output rate is the main purpose of energy saving is different from the 1 in
- Q: What does "frequency" in household appliances mean?
- The technology of frequency conversion technology called frequency conversion technology and home appliances in 1970s AC control by changing the frequency of the AC current, household appliances gradually began to appear frequency, electromagnetic cooking device, inverter lighting apparatus, inverter air conditioner, microwave frequency, variable frequency refrigerator, IH (induction heating cooker), inverter washing machine etc.. In the latter half of 1990s, household appliances relied on frequency conversion technology, mainly aiming at high function and power saving. For example, with high speed, high output, good control performance, small light weight, large capacity, high comfort, long life, safe and reliable, mute, power saving and so on.
- Q: Does the number of inverter settings differ from the number of motor poles, and does it affect the use?
- When the number of poles of the motor is corresponding to the speed of the motor and the number of the poles is not set, the speed is controlled, and the speed is very difficult to drive.Frequency converter (Variable-frequency, Drive, VFD) is the application of frequency conversion technology and microelectronics technology, by changing the power supply frequency of the motor to control AC motor power control equipment. The frequency converter is mainly composed of rectifier (AC DC converter), filter, inverter (DC AC converter), brake unit, drive unit, detection unit, micro processing unit and so on. Inverter by internal IGBT drive voltage and frequency off to adjust the output power, the power supply voltage required to provide according to the actual needs of the motor, so as to achieve the purpose of speed, energy saving, in addition, there are a lot of protection drive, such as over-current, over-voltage, overload protection and so on. With the continuous improvement of the degree of industrial automation, inverter has also been widely used.

- Q: Is the voltage low? The younger brother is bored to death, no problem with the wire drawing machine, the full load will jump off. Display frequency converter overload and acceleration operation overcurrent. Help me please.
- There are only three reasons for the POFF fault: (1) the DC bus voltage detected by the machine is seriously low. (2) lack of phase signal. (3) the voltage level parameter of 220V machine is wrong. [method] use the shift key on the keyboard or the mask to switch the display content to the display bus voltage status.
- Q: What role does input and output reactor play?
- The working principle of the reactor: the interference of capacitance and inductance in the circuit to the AC is called reactance. The inductor has the function of restraining the change of the current and the phase shift of the alternating current, and the winding static induction device with inductance is called a reactor. The dead are common reactor used in the power system with series reactor and shunt reactor. Series reactors are mainly used to restrict short circuit currents, and are connected in series with or parallel with capacitors in filters to limit the higher harmonics in the power grid. Reactors in the 220kV, 110kV, 35kV, and 10kV power grids are designed to absorb charging, capacitive, reactive, and reactive power in cable lines. The operating voltage can be adjusted by adjusting the number of shunt reactors.
- Q: What's the difference between universal inverter and fan pump converter?
- Fan and pump load:In a variety of fans, pumps, oil pumps, with the rotation of the impeller, the air or liquid within a certain speed range of resistance is roughly proportional to the speed of the 2 side of the n. As the speed decreases, the torque decreases by 2 times the speed. The power required for this kind of load is proportional to the 3 power of the velocity. When the required air volume and flow rate are reduced, the frequency and speed of air flow can be regulated by the frequency converter, so the energy can be saved substantially. Because the power required at high speed increases with the speed, and is proportional to the speed of the three side, so the fan and pump load should not be used in the ultra power frequency operation
