- Q:The functions of frequency converter and UPS are similar, especially the power frequency UPS?
- Frequency converter is the application of frequency conversion technology and micro electronics 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.UPS is an uninterruptible power supply, including an energy storage device, a rectifier, inverter as the main component of the regulator, frequency stabilized AC power supply. The main use of battery energy storage power supply device to provide uninterrupted computer / server, storage equipment, network equipment, computer communication network system and industrial control system, need continuous operation of industrial equipment in power outages. When the power input is normal, UPS electric voltage supplied to the load, the UPS is an AC electric regulator, it is also to the storage device such as a battery charging; when the power interruption (outage), UPS immediately to the storage device (such as batteries or fly wheel the electric energy storage system), continue to supply alternating current to the load by the method of inverse transformation, the load to maintain normal working and protect the load of software and hardware is not damaged.
- Q:What is the main harmonic produced by a transducer? How about the degree?
- The frequency converter is a nonlinear load, which absorbs nonsinusoidal current from the grid and causes the voltage distortion of the network. It is not only a harmonic source, but also a harmonic receiver. As harmonic source, it has different influence on all kinds of electric equipment, automatic device, computer, measuring instrument and communication system. As for the power supply line, due to the harmonic effect, the quality index of the power grid is deteriorated, the reliability of the power grid is reduced, the loss of the power grid is increased, and the service life of the electric equipment is shortened.
- Q:How do two inverters synchronize?
- Use a potentiometer to control which one is in front. Which of the following uses synchronization to track speed and position?. (a PLC (or a special control panel) + position sensor (can be a variety of proximity switch + CAM) two, there must be a little better, by rotating the transcoder, can also be used for phase control of motor position relative to the strict requirements).
- Q:What does "EPCU" mean in a frequency converter?
- This is the frequency converter BlueOcean Huateng, they said this code external signal interference, you are not the power line and the signal line to go ah, check the external line, then no problem on the phone to the factory
- Q:What is the over-current of the inverter?
- The reason of the frequency converter itself:?1, parameter setting problem: for example, the acceleration time is too short, the PID regulator's proportion P, the integral time I parameter is unreasonable, the overshoot is too big, causes the frequency changer output current oscillation.?2 、 frequency converter hardware problem:
- Q:What's the use of switching frequency of converter?
- The chopper device also has switching life, the higher the switching frequency, the shorter the life of the inverter, and will reduce the inverter output current and power. The smaller the chopping frequency, the higher harmonic content and the more serious harmonic pollution.
- Q:How does the frequency converter change the voltage and change the speed of the motor?
- The inverter does not change the voltage to adjust the speed of the motor. Under the premise of constant voltage, the frequency of the alternating current is changed to adjust the speed of the motor. Typically, at the frequency of 50Hz, the synchronous speed of the quadrupole motor is 1500 rpm, and if the frequency is increased to 60Hz, the synchronous speed should be 1800 rpm; if it falls to 40Hz, the synchronous speed should be 1200 rpm. In the limited frequency range, the power is constant, the higher the speed, the smaller the torque, the lower the speed, the greater the torque. Formula for speed calculation (Rev / min):60 seconds * / log polar frequency. The middle pole of a pair is 2 poles of 1 pairs, i.e., the quadrupole motor is 2 pairs of magnetic poles.The frequency of the converter is stepless, continuous and adjustable, so the speed of the motor is continuously adjustable in a certain range.
- 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:What is the difference between inverter energy consumption braking and motor energy consumption braking?
- When the motor is disconnected from the power supply, in order to make the motor stop quickly, using the power control method in motor power supply coupled with the normal operation of power supply phase at this time, the direction of rotation of the rotation direction of the motor rotor and the motor rotating magnetic field in electromagnetic force at the moment is generated by the motor brake torque, motor speed reducer. Using the Q switch voltage at both ends of the armature is disconnected from the power grid, and it will immediately receive a braking resistor RL, at this time, the main magnetic field in the motor armature remains unchanged, the cause inertia continues to rotate the torque braking torque, the motor speed down, until the stop.
- Q:How do you understand the ramp up (descent) time of the inverter? Thank you!
- The ramp up time is to start from the 0 speed, inverter, running to reach the given speed (for example: 1420) the time required, in general, the longer the time, the frequency converter and motor impact is small. In the actual work process, according to process requirements to set the length of time. (more than 10-15 seconds) or so, if it is a pump or fan motor, do not need to change its rise time, the default can.
