Q:What does "G" and "P" mean in the converter model?
Frequency converter (frequency transformer) is usually the use of power semiconductor devices through the role of switching the power frequency to another frequency power control device. The main circuit of the inverter can be divided into two categories: voltage is DC voltage source converter for AC inverter, the DC circuit is the filter capacitor current is DC converter; current source for AC inverter, the DC circuit filter inductance.
Q:What is the difference between SIEMENS inverter and built-in filter?
There is no built-in filter converter in the price slightly lower, mainly used in the equipment efficiency (power factor) requirements are not high, anti-interference ability requirements are not strict place;The frequency difference with built-in filter is mainly to the requirements of different electrical parameters in specially designed, can improve equipment (power factor), has the good anti-interference ability, prevent the transient surge of inverter module impact, has a good protective effect.
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 the difference between a frequency converter and a saver?
According to the frequency above 3 disadvantages, we developed and produced for Saver series under different conditions, based on frequency conversion technology, according to the field of electricity, increase control cabinet, electric / power conversion system, load detection and control system, input and output filter, DC reactor device etc.. The economizer has 4 advantages over the inverter:
Q:The difference between soft starter and converter
The soft starter is just a thyristor pressure regulating device is simple to start the motor, the motor speed can not be normal, low price; inverter is the AC power supply voltage and frequency, can IGBT chopper can be used to start the motor, can also be normal speed, the price is relatively expensive
Q:How to maintain the frequency converter will not damage, or regular maintenance?
1. cooling fan, inverter power module is the most serious heating device, the continuous heat generated by the work must be promptly discharged, the general fan life of about 10Kh-40Kh. According to the continuous operation of converter for 2-3 years, it is necessary to replace the fan2. filter capacitor, intermediate circuit filter capacitor: also called electrolytic capacitor, its main function is to smooth the DC voltage, absorb the low-frequency harmonic in dc.
Q:What does the base frequency 60Hz represent in the inverter?
If the motor chooses a special AC frequency conversion motor, the motor is always marked with constant torque and constant power speed range. For example, Mark 5 ~ 100HZ for constant torque, 100 to 150HZ for constant power, the basic frequency should be set to 100HZ. The fundamental frequency parameter directly reflects the relationship between the output voltage and the output frequency of the inverter. If it is not set properly, it is easy to cause the overcurrent or overload of the motor. For example, an AC motor rated voltage 380V, rated frequency is 60HZ, if the frequency is lower than that of converter 60HZ V/F, a high proportion of the output voltage as high frequency, high output current, at startup, easy to cause the flow. If the frequency converter is set higher than 60HZ, low V/F ratio, the output voltage of the same frequency is low, the output current is low, at startup, can easily lead to the start and overload.
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:Does the number of inverter settings differ from the number of motor poles, and does it affect the use?
1. motor speed control will not be accurate2. the working current of the motor may become larger, and the motor will be burnt out3., excitation what will change, but also may cause the motor heating, burnout, will also reduce the efficiency of the motor;4. may also burn the inverter.5. motor output may be affected.
Q:What is the working principle of a three phase AC asynchronous motor inverter?
I. operating temperature. The internal electronic components of high power, extremely easy to be influenced by the working temperature of the product, the general requirements for 0 ~ 55 degrees, but in order to ensure the safe and reliable work, use should 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 in the product specification. Absolutely no heating element or easy heating element shall be installed on the bottom of the converter.
