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 ...

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 ...

1. The power and temperature rise of the motor Regardless of the method of the inverter, different degrees of harmonic voltage and current occur during operation, so that the motor runs under non-sinusoidal voltage and current. Rejection of material introduction, taking the sine wave PWM type inverter that is now widely used as an example, ...

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.

The selection of the acceleration form and deceleration form of the inverter is also called the selection of acceleration and deceleration curves. Generally, there are several forms of inverter, such as linear, S-shaped, semi-S-shaped, etc., and the characteristics and uses of each form are as follows. 1. Linear form The form makes the inverter ...

The motor itself: 1) The inner and outer rings of the bearing are too tightly cooperated. 2) There are problems with the shape and position tolerance of parts, such as the coaxiality of parts such as machine base, end cover, shaft and other parts is not good. 3) Improper selection of bearings. 4) The bearing is not smooth or the bearing is not clean, and there are impurities in the smooth grease. ...

1. Overpressure leads to brake pipe breakdown. The so-called overvoltage of the inverter refers to the fact that the inverter voltage formed due to various reasons exceeds the additional voltage, which is concentrated in the DC voltage of the inverter DC bus. The overvoltage alarm generally appears at the time of shutdown, and its main ...

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: ...

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. ...

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. 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.

1. Appropriate working environment 1. The ambient temperature is suitable All manufacturers have certain rules for active temperature control cabinets. The PLC promises that the ambient temperature is usually about 0 to 55 ° C, so during the equipment process, this heating element is not placed in the PLC; The PLC should have adequate ventilation and ...

(1) Frequent starting, resulting in excessive temperature, causing overheating maintenance of soft starter. (The number of starts of the soft starter should be controlled to no more than 6 times per hour, especially for heavy loads) (2) During starting, ...

Common troubleshooting methods for Reynolds soft starters. 　　During the debugging process of the soft starter, the fault light is on, the motor is unresponsive, and the cause of the fault is analyzed: When the starting mode adopts the live mode, the operation sequence is wrong (the correct operation sequence must first deliver the main power supply, and then the control ...

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 ...

There are two types of inverter parking. One form is called "free parking". As the name suggests, it is to quickly "power off" the motor, so that the motor can slide and park by its own inertial force (OFF2 parking); The other form is called "brake parking". So this "brake parking ...

Reynolds inverter fault codes: E.bC Reynolds inverter fault phenomenon/type: Brake unit failure 　　​ 　　Reynolds inverter failure may be caused: 1. Brake line failure or brake ...

Voltage level: The voltage level should match the voltage level of the power supply and motor to ensure electrical safety and normal operation of the equipment. Current level: The current level should match the rated current of the motor to ensure electrical safety and normal operation of the equipment. Cable Specification: Cable ...

The inverter has power loss during operation and converts it into heat energy, which increases its own temperature. Roughly speaking, the power loss of every 1kVA inverter capacity is about 40W-50W. Therefore, when installing the inverter, it is necessary to consider the heat dissipation of the inverter, and how to run the inverter.
