System Principle of High Voltage 6KV Frequency Inverter

High Voltage 6KV Frequency Inverter

Q: Can the inverter stop intermittently during operation? If so, how to connect and set up: and the corresponding function of these terminals, you have to in the inverter Set up.

Q: What is the difference between variable frequency motor and variable speed motor?: The variable frequency motor requirements are high, are special motor, so the general motor can not use the inverter to speed. According to the above formula, it can be seen that increasing the frequency, the motor speed will be faster, reduce the frequency of the motor speed is slow, variable frequency motor core is also a special material, because the ferromagnetic material There is a saturation period, to the saturation period, regardless of whether the motor current increases, the motor will not continue to increase the intensity of the magnetic field,

Q: Laptop power adapter leakage: Not a leakage of electricity, switching power supply design is the need for anti-interference caused by the leakage current, a lot of adapters have this phenomenon, but no harm to the human body is safe, you do not have to buy to replace, the original is good. If you have a protective ground at home, then you can not feel the leakage, because the leakage current from the protection of the ground to the earth, and really leak, then your home leakage protector on the trip.

Q: Notebook plug in the power adapter lights, but can not open the machine: 1. Remove the power adapter and battery, the host does not power the case, hold down the boot button does not move, keep the notebook 30 seconds to release the residual static electricity; 2. Connect the power adapter separately to try to power on; 3. Connect the battery separately to try to boot; 4. If conditions permit, you can plug the memory test.

Q: The inverter is running independently: Frequency conversion regulator is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment. The inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on. The inverter will adjust the voltage and frequency of the output power supply according to the breaking of the internal IGBT, and provide the required power supply voltage according to the actual needs of the motor, so as to achieve the goal of saving energy and speeding.

Q: Inverter ACS355 If the speed is outside the allowable range, how to set the limit value: 1. Set 2002 MAXIMUM SPEED Defines the maximum permissible speed.

Q: What is the difference between the collector and the emitter mode?: While the base area should be very narrow So bjt is not a symmetrical device

Q: Short-term short-circuit converter DC link positive and negative will damage the inverter?: This short circuit may not necessarily line, the inverter fan has three, one is no speed line, two are pulse, three are switching signal (this is very little, I only encountered several),

Q: Oil-free vertical vacuum pump why a little negative pressure inverter on the torque limit: and then use the inverter into three-phase AC, 380 volts almost, Can only use the transformer rose to 380 volts.

Q: What is the IGBT? Our inverter IGBT fried,: Basically change the voltage, the voltage changes in accordance with the different frequencies, so that change the speed.
