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's the difference between universal inverter and fan pump converter?: Constant power load:The torque required by machine spindles and rolling mills, paper machines, and plastic film production lines is generally inversely proportional to the rotational speed, which is called constant power load. The constant power nature of the load should be in terms of a range of speed variations. When the speed is very low, the mechanical strength limit, TL can not be infinitely increased, at low speed into a constant torque nature. The constant power area and the constant torque area of the load have a great influence on the choice of transmission scheme. When the motor is in constant flux speed regulation, the maximum allowable output torque is constant, which belongs to constant torque speed regulation. While in the speed regulation of magnetic flux weakening, the maximum allowable output torque is inversely proportional to the speed, which belongs to constant power speed regulation. If the constant torque of the motor and the range of constant power speed are consistent with the constant torque of the load and the range of constant power, the capacity of the motor and the capacity of the converter are all the smallest, which is called "matching".

Q:Check the fault information is the power supply voltage instability, but other inverters are running well, what is the matter? Will there be any other parameters are not set correctly, thank you!: Ha ha, we have a problem, always complicate the problem, always used to find problems from the frequency converter, but did not think the problem is in the most basic place......

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:What is the frequency converter AVR?: When the input voltage deviation from the rated value, the function can keep the output voltage constant, so under normal circumstances should be AVR action, especially when the input voltage is higher than the rated value, to protect the motor from excessive voltage caused by long-term insulation damage or high magnetic density caused by excessive heating core.

Q:What are the key points of frequency converter maintenance?: 1., regular cleaningAlways check the frequency converter regularly and keep the environment clean and dry. It is strictly prohibited to place sundries near the frequency converter, and someone should regularly clean the frequency converter, blow it out, keep the cleanliness of the converter and the ventilation of the air duct.2. treatment methodsIf it is found within the inverter or radiator plate dust and debris falling into, should promptly use compressed air to blow off. Clean air filter, cooling air duct and interior dust. When it is found that the conductor and insulator have corrosion, it should be promptly cleaned with alcohol.For continuously running inverters, the running state can be visually checked from outside. Periodically inspect the converter and check if there is any abnormality when the converter is running. The following tests should normally be carried out:

Q:When the inverter is running at full 50HZ, the output voltage decreases and the output current becomes smaller. What is the reason?: I don't know if you're a manufacturer of car gearboxes, and we've also done car engine tests. The operation in the 50HZ when the inverter is not reduced voltage, if only a little decrease will decrease, this is due to increasing frequency, controllable silicon resistance increases, the corresponding motor voltage decreased slightly, not what the essence of influence.

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:What are the precautions for frequency converter wiring installation?: First understand the instructions, do not take the control line wrong, power line into the wire outlet is connected, you can debug it

Q:What is a frequency converter?: VVVF: change voltage, change frequency CVCF: constant voltage, constant frequency. AC power supplies used in various countries, whether for homes or factories, have voltages and frequencies of 400V/50Hz or 200V/60Hz (50Hz), and so on. Normally, a device that changes the alternating current of voltage and frequency to a voltage or frequency variable alternating current is called a frequency converter". To produce a variable voltage and frequency, the device first transforms the alternating current of the power source into direct current (DC).
