Q:What is the traction frequency converter for electric cars?
Optimal energy utilization.The optimal utilization of energy is another basic requirement of electric vehicle, the control system can be as much as possible the use of energy, including the use of overheating and regenerative braking energy, make full use of limited energy. Ability feedback can implement this function. It includes two kinds of vehicle braking capability feedback and vehicle coasting ability feedback. In our state, the drive motor according to the operation of the generator, the vehicle kinetic energy into electricity, can play 3 roles: auxiliary braking; energy recovery to the power battery, thereby prolonging the vehicle mileage; in vehicle heating demand, can directly use this energy heating.
Q:How to choose frequency converter?
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.
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:Frequency converter size selection
Motor 90KW, frequency converter, 90KW can be applied, but the frequency can not exceed the rated value of the motor. There are some occasions to live and use the frequency converter to speed up the motor, so it should be chosen a little larger, otherwise the inverter will be more loaded.
Q:How does the frequency converter fit the brake unit and the brake resistor?!
Using these kinetic energy, the brakes can be used, like the brakes of a car, by turning kinetic energy into heat energy to consume the kinetic energy of the motor shaftAnother way is to say that you use a braking unit with a set of braking resistors. The principle is to change kinetic energy into heat, and use electrical resistance to heat up the kinetic energy of the motor
Q:Ask, what is the ratio of frequency converter?
Rotating main potentiometer, respectively, to see the three frequency converter F1.00 parameters, keyboard digital display reference input, follow potentiometer changes, and the proportion of 1:1.5:2. Rotate three trimmer potentiometers respectively, and the reference input of the corresponding converter has little change.
Q:How does the PLC process the inverter output signal?
Frequency converter frequency signal will actually be converted to 4-20mA signal output, access to the PLC AI channel, SIEMENS 200 PLC, some CPU module comes with AI input, but also has a dedicated AI expansion module. What's left is software programming
Q:What is the upper and lower limit of the environmental temperature to ensure the normal operation of the inverter?
Inverter environment temperature(1) working temperature. The use of frequency converter should pay attention to the environmental matters, the internal is high-power electronic components, is easily affected by the operating temperature, the product is generally required to be 0~55 degrees, but in order to ensure safe and reliable work, when usedShould be considered under the best control in 40 DEG C. In the control box, the inverter shall be installed on the upper part of the box, and strictly comply with the installation requirements of the product manual, absolutely not allowed to sendA heat element or a heat generating element is mounted close to the bottom of the inverter.
Q:What are the differences between electronic governor and frequency converter in motor speed regulation?
The electronic governor is used to change the power supply voltage of the motor by controlling the turn-on angle of the thyristor, so as to change the characteristic curve of the motor to change the speed of the asynchronous motor. Its characteristics are as follows: the motor speed adjustment range of small, low speed motor with load capacity, speed is reduced, the motor torque decreases, not for constant load moment, when the speed is low, easy blockage phenomenon; generally applies only to fan type load.
Q:What is the difference between a converter and a transformer in Yu Na?
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
