Product Description:

Medium Voltage Drive VFD 440KW 3.3 KV HIVERT-Y 3.3/096

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 general MV VFD has the following protection functions and features:

The RMVC 5100 provides speed and/or torque control for Solution for a wide range of industries
motor-driven applications in the medium and high power
range from 200kW to 14 MW at motor voltages from 3.0kV
to 13.8 kV.
It is available with air cooling in the lower power range and
with optional water cooling in the medium to high power
range. RMVC 5100 drives are also available mounted
within a customised container, with self-contained sealed
cooling systems, providing the highest IP class ratings for
hostile environments as well as providing greater
convenience and ease of installation and commissioning.

Q:There is no inverter comes with simple PLC programming function
Inverters are generally digital input, and analog input, a digital output, etc., can also be controlled by means of communication. Digital input can be used as a positive and negative and reset the alarm, the analog input can be given as a speed, and how to use the inverter to see the specific model. Take the Siemens inverter, MicroMaster420,567 terminal 3 digital input, 8 for the 24V, 9 for the 0V, you can usually open the point on the 8th 24V back to 567, as a digital input, you can also directly into the switching power supply Of the 24V, but the switch power supply 0V and 9 terminals connected to the potential, or the inverter may not be able to identify the outside world 24V. (DP communication, USS communication, etc.), with the terminal input on the P0700 = 1, the user can set the command source, the panel can be input, 2, P0701 to P0703 corresponding to the three digital functions: parameters set to 1 forward, 2 for the reverse ... ... a lot of features and control methods, see the corresponding product manual like
Q:What is the working principle of high voltage electrodes and frequency converters?
High voltage inverter from high - low - high; low - high; high - high points. The following are the same as the " High-low-high-mode high-voltage inverter is the high-voltage power transformer with a step-down, with low-voltage inverter control, and then step up the transformer voltage to the voltage we use, the supply of high-voltage motor.
Q:What is the difference between the electronic governor and the frequency converter on the motor speed regulation?
Electronic governor is the use of control thyristor conduction angle to change the motor supply voltage, the motor characteristics of the curve down to change the speed of asynchronous motor. Its characteristics are as follows: the motor speed adjustment range is small, low speed when the motor load capacity is poor, the speed decreases, the motor torque decreases, not applicable with constant load, when the speed is low, prone to stall phenomenon; Applicable to fan load. Inverter speed is to change the frequency of the motor to achieve the AC asynchronous motor speed adjustment, speed adjustment balance, the motor load characteristics do not change with the speed change, suitable for load adjustment and constant torque adjustment. Excellent performance, but the cost is higher.
Q:Is the laptop power adapter high temperature normal? Is there anything else?
Normal, my power adapter is also very hot, generally ignore
Q:Master Hello a machine requires 500 speed matching 6-pole motor frequency converter transferred to about 28HZ
The belt rotation is calculated by the speed ratio. The current transferred to the motor by the inverter is approximately equal to the rated current of the motor, ie the motor's power is maximized.
Q:Yasukawa inverter reported bb code that is the reason why the base blockade?
This is not a fault! Only after the inverter receives the base block signal, it is not output!
Q:Motor nameplate on the standard 2P, I set the number of motor pole in the inverter, is set 2 or 4 pole?
n the motor pole, an Antarctic (S pole), an Arctic (N pole), calculate a pair of poles, the number of pole pairs is how many such "pairs" (S pole + N pole). 2 pole motor --- pole pairs 1 = P = 1,4 pole motor --- pole pairs 2 = P = 2, and so on.
Q:Yaskawa inverter reported base blockade what is the reason?
Yasukawa compared garbage on the signal board on the small line of poor oxidation, and get like, this is a weak signal, and safety relays connected, do not use high-grade security circuit with a small line short, Yasukawa A 1000 factory is short for a long time after the oxidation of the base blockade
Q:380V 2 pole motor can use the inverter?
Of course, the stator winding can be connected with concentric While enameled wire to be better, preferably 180 degrees or 155, and even dedicated enameled wire
Q:2 pole 0.75 kW motor can increase the speed through the inverter?
2-pole motor speed of about 2900 r / min or so, 4-pole motor speed of about 1400 r / min or so, which are in the case of 50HZ,
