The internal structure of the inverter is the role of Reynolds

1. The inverter itself has a strong electromagnetic disturbance, which will disturb the work of some equipment, so we can add a cable sleeve to the output cable of the inverter. 2. The control line in the inverter or control cabinet is at least 100mm away from the power cable, etc. ...

The cost performance of Reynolds JJR5000 soft starter is relatively high, which is mainly reflected in the following aspects: 1. The price is more reasonable: compared with other similar products, the price of Reynolds JJR5000 soft starter is more affordable, and the price is in a more advantageous position among the products of the same level.

1. The cause of the leakage problem Some sites use frequency converters to control the motor, which will present the problem of leakage, and the leakage voltage ranges from tens of volts to 200 volts. In view of this problem, the reasons for this shortcoming are theoretically expounded and stated as follows. Depend on...

(1) The multi-pronged PWM control method is selected, and the output voltage waveform is close to the sine wave. (2) The rectifier circuit is multiplied, the number of pulses is as high as 36, the power factor is high, and the input harmonic is small. (3) Modular design, compact structure ...

Installing a variable-frequency drive (VFD) on the power frequency motor can complete the precise control and speed regulation of the motor, and improve the power and accuracy of the progressive motor. However, if it is not properly used and used, the following damages may occur: ...

1. The constant pressure water supply of the inverter increases the comfort of water supply by 3 times 2. Constant water pressure, reducing pipe bursts and leakage by 80% 3. High efficiency and energy saving, power saving effect up to 20%-60% (depending on the actual situation) 4. The use of frequency converters can realize multi-point pressure in different time periods.

As an electronic electric, the inverter itself also consumes electricity (about 3-5% of the additional power). A 1.5 hp air conditioner consumes 20-30W of electricity, which is equivalent to the length of a lamp. The inverter works under the power frequency and has the function of saving electricity, which is practical. But the conditions are: At the top of the list, great success ...

Low pressure issues The VFD reports a low voltage issue when the drive's DC link voltage drops below 62% of the nominal level at the high setting (480 Vac) and 50% of the nominal value at the low setting (400 Vac). The +10% and -15% voltage tolerances in most manuals are the ones that claim to be ...

The inverter motor is equipped with a mechanical brake, is the inverter motor in the power generation condition when parking? Is the brake unit of the inverter working at the moment? What are the causes of brake unit damage? Answer: 1. The inverter motor is equipped with a mechanical brake, and when parking...

Soft starters and frequency converters are two completely different products. The inverter is used in the local area where speed regulation is required, and its output not only changes the voltage but also changes the frequency at the same time; A soft starter is actually a voltage regulator, which is used when starting a motor, and the output only changes the voltage and does not change the frequency. Change...

When it is required to wiring outside the frequency conversion cabinet, it is generally necessary to use the conduit for wiring, which requires suitable mechanical pressure and unsuitable mechanical damage, moisture-proof and corrosion-resistant. Conduits include the following two wiring methods: 1. Kim ...

A frequency converter is a power electronic device that can change the frequency of an AC power source to control the speed and output power of a motor. Inverters are widely used in industry, aviation, metallurgy, petroleum, chemical industry, electric power and other fields.

That is, the upper and lower amplitudes of the output frequency of the inverter. Frequency is a maintenance function to avoid misoperation or failure of the external frequency setting signal source, which causes the output frequency to be too high or too low, so as to prevent damage to the equipment. You can set it according to the actual situation in the app. This function can also be used as a speed limit, so that ...

In order to measure stable harmonics, it is necessary to meet the following two conditions: At the top of the list, the signal is a stable periodic signal. Second, it is necessary to perform harmonic analysis according to the integer multiple of the period of the stable periodic signal. ...

Because inverters are widely used, there are many differences in the corresponding types and specifications. We are broadly divided into two categories: voltage and current. The current type of inverter products is characterized by the use of a large inductor as the energy storage link in the middle DC link, and the reactive power will be buffered by this inductor. ...

General treatment methods for inverter overcurrent problems: The output side of the inverter is a PWM voltage waveform, and after passing through the motor winding, the output current is approximately a sine wave, and lags behind the voltage by a phase viewpoint, which is determined by the power factor of the motor. The output current of the inverter passes through ...

After selecting the resistance value of the braking resistor, the power value of the braking resistor should be confirmed, and the selection of the braking resistor power is relatively cumbersome, and it is related to many factors. The instantaneous power consumed by the braking resistor is calculated according to the following formula: P instantaneous = ...

1) The air duct of the inverter cabinet should be planned reasonably, and the exhaust should be clear and smooth, so as to avoid the formation of vortex in the cabinet and the accumulation of dust in a fixed direction. 2) The top air outlet of the inverter cabinet should be equipped with a protective top cover to avoid debris from falling directly.
