Perfect Power Output Section
The HIVERT general MV VFD adopts the power cells connected in series and voltage overlapping method (i.e. Power cells multi-level cascade technology), it can output the perfect PWM sinusoidal waveform (see Figure 2 and Figure 3). It has the following advantages:
1. No need for the additional output filter
2. Directly driving general synchronous or asynchronous motor
3. No de-rating operation on the motor
4. No dV/dt stress on the insulation of motor and cables
5. No torque ripple, extending service life of motors and mechanism
6. No cable length restriction within the acceptable voltage drop.
The application of advanced technology variable speed
drives to motor control results in significant energy savings
over fixed speed in a wide variety of applications.
Since their introduction to the market in 2005, the RMVC
range of variable frequency drives have provided reliable
and highly efficient control of medium voltage AC motors
for many applications in a wide range of industries.
The RMVC 5100 series is the latest generation optimised
for improved performance, reduced size and weight and
even greater value for money.
- Q: Laptop adapter
- This principle is not, try, look at how the charge situation, if you can charge, can be filled, just a long time, to no harm However, the heat may be high, long-term so, there is a risk
- Q: What parts of the inverter composition
- Frequency control technology is an important development direction of modern power transmission technology, with the development of power electronics technology, AC frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply and other fields. However, due to the environment, the use of life and man-made operation and other factors, affecting the life of the inverter greatly reduced, while the use of a variety of failures have occurred. Here we are on the composition of the inverter and common problems and countermeasures and we discuss. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.
- Q: Three-phase asynchronous AC motor speed control method
- Second, the frequency control method Frequency control is to change the frequency of the motor stator power supply, thus changing its synchronous speed control method. Frequency converter system can be divided into AC - DC - AC inverter and AC - AC inverter two categories, most of the current domestic use - cross - frequency converter. Its characteristics: High efficiency, no additional loss during the speed control process; Wide range of applications, can be used for cage type asynchronous motor; Speed ??range, the characteristics of hard, high precision; Complex technology, high cost, maintenance and repair difficult. This method is suitable for applications requiring high precision and better speed performance.
- Q: The relationship between the power supply of the notebook and the battery
- 1, when the notebook battery is fully charged, and connected to the power adapter, usually by the adapter directly to the host power supply, this time the battery is idle, the adapter power supply without battery conversion.
- Q: I have a 11KW-4 pole inverter, now with the 4KW-4 pole motor, what impact?
- that is, the load is very heavy; caused by over-current burning inverter
- Q: Speed regulation method of three - phase asynchronous motor
- Change the number of pole pairs can be adjusted, in the way around the stator coil through the tap method can achieve two-speed. With the popularity of the inverter, three-phase asynchronous motor speed mostly with the inverter.
- Q: There is no inverter comes with simple PLC programming function
- The PLC is programmed to handle digital and analog, the core of the entire control system. It can output the digital to the inverter, so that the inverter is reversing, you can output the analog to the inverter set speed, but also through the communication, direct control inverter
- Q: Does the inverter set the number of poles to match the number of poles of the motor?
- The inverter will adjust the voltage and frequency of the output power by the breaking of the internal IGBT, according to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition, the inverter has a lot of protection , Such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, the inverter has also been a very wide range of applications.
- Q: 55 瓩 4 pole motor with a frequency of one hour can save much electricity
- it is used in the fan pump load can save about 14-22 kWh, used in the general category, on Multiply your number by 55.
- Q: How to learn the inverter debugging and design parameters
- You can find the basic inverter manual, see a few times to try, under normal circumstances, the inverter on the use of manual functions such as research to understand that most of the applications are no problem.
