The system power is equal to the product of the power of a general-purpose inverter and the power of the motor. As long as both work efficiently, the system power will be higher. From the perspective of power, when choosing VFD power, you should pay attention to the following points: VFD ...

1. It is necessary to consider the touch and current size of the incoming terminal, if the terminal standard is small, perhaps the conductive function of the terminal is poor, which will directly cause the current carrying capacity of the terminal to be small and heated. 2. The inlet at the end of the inlet line must be pressed well and the like, if it is not pressed, it may cause ...

1. Transfer heat pipes for heat dissipation. In many applications, heat generated from the base steel plate of the power module is transferred through the heat transfer components to the distant surface of the heat pipe. In this way, the temperature of the base steel plate of the power module will be equal to the temperature of the heat pipe heat dissipation surface, the temperature of the heat transfer parts, and the temperature of the two contact ...

1. The interval between the inverter and the motor should be as short as possible. This reduces the cable's capacitance to ground and reduces the source of disturbance. 2. The control cable is shielded cable, the power cable is shielded cable or from the inverter to the motor.

Short-circuit maintenance is a function of equipment connected between the power supply and the load, which can effectively disconnect the short-circuit point from the power supply when the load side is short-circuited. If an equipment has a short-circuit maintenance function, it must have a certain short-circuit breaking ability; And a device with the ability to break in a short circuit ...

1. Advanced technology: (PC or PLC) is used to make the equipment complete the intelligent constant pressure variable supply water supply according to the requirements of water supply and fire protection; 2. High efficiency and energy saving: the system can set the pressure according to the demand, and the system can actively adjust according to the set pressure.

When it comes to inverter repair, it's not enough to understand the above fundamental circuits, but also to understand the following primary circuits. The main circuit is mainly composed of rectifier circuit, current limiting circuit, filter circuit, braking circuit, inverter circuit and detection and sampling circuit. ...

With the improvement of the degree of automation of packaging machinery, packaging machine inverter (hereinafter referred to as VFD) plays an increasingly important role in packaging machinery. Capsule filling machine, high-speed tablet press, bottling production line, aluminum-plastic packaging machine, cartoning machine, each equipment will use VFD, mainly ...

1. Classified according to the input voltage level According to the input voltage level, the inverter can be divided into low-voltage inverter and high-voltage inverter, and the low-voltage inverter is common in China with single-phase 220 V inverter, three-phase 220 V inverter, and i-phase 380 V inverter. High-voltage inverters are commonly used in 6 kV, 10 kV transformers.

From September 23rd to September 25th, 2020, the 2020 China International Paper Technology Exhibition was held in Hall D1 of Suzhou International Expo Center.

Many people don't have a clear idea of the detailed differences and uses of AC converters and power savers. Power savers are generally divided into lighting appliances and power savers. Using high-voltage filtering and energy absorption skills, it automatically absorbs the energy of the reverse potential of high-voltage power equipment, and continuously feeds back ...

Compared with the motor driven by the inverter, the power factor and efficiency of the motor will deteriorate and the temperature rise will increase because the output waveform of the inverter contains the influence of higher harmonics. On the other hand, when the frequency conversion is driven, the same torque should be obtained as when the power frequency power supply is driven, ...

When the high-power motor starts, the current is large, which will cause the grid voltage to be seriously shaken, in order to deal with this problem, the general requirements for speed regulation are not high, and the soft engine can be used to reduce the voltage and start. However, the drop in the starting current when the step-down is started will also make the starting torque drop significantly.

More than 40 sets of RNSVG series low-voltage power generator sets and RNZB series high-voltage reactive power automatic compensation devices designed and produced by Reynolds have been successfully completed and will be delivered in the near future. This product is owned by Shanghai Reynolds ...

Frequency conversion speed regulation is to change the power supply frequency through the frequency converter, and then adjust the motor speed to improve the operation efficiency of the electric drive system. Depending on the current, VFDs can be divided into AC-DC-AC type and AC-AC type. At present, the most widely used in China is the AC-DC-AC type. ...

In order for a VFD to operate reliably for a long time, it is necessary to repair the electronic components in the VFD on a regular basis and replace the primary components of the VFD according to the service life. 1. Cooling fan The VFD power module is the most heat-generating device, and its ...

Low pressure issues The VFD reports a low voltage glitch 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 ...
