The given way of the inverter - LS generates electricity

1. The speed of the motor slows down, and the cause of the problem of sound disorder may occur in the electronic speed stabilization device and the motor itself. If there is no problem with the power supply, most of the motor itself has a problem. It can be repaired by replacing the new motor and dismantling and repairing the motor. Dismantling and repairing the motor ...

When LS PLC is put into operation, its operation process is generally divided into three stages: input sampling, user program fulfillment and output rewriting. The completion of these three phases is called a scan cycle. During the entire operation, the PLC's CPU repeatedly performs the ...

Due to the short circuit of the load, the failure of the self-oscillation circuit and the loss of control of the protection circuit, the switching power supply will cause the base of the switch tube to be unable to get the switching pulse and intermittent operation, which makes it difficult to locate the shortcomings of SMPS. The difficulty of the repair operation and the improper method will expand the shortcomings, constituting the phenomenon of continuous burning of the switch pipe, etc., ...

Alternating current can be converted into direct current using rectifier electricity, but in three-phase electricity, this DC voltage or current contains voltage or current ripple with a frequency of six times the frequency of the power supply. In addition, the inverter inverter will also generate ripple voltage or current due to output and carrier frequency, etc., and reverse ...

When using an inverter, a leakage maintainer must not be used. This is a major criterion for the use of frequency converters. Some users choose the corresponding leakage maintainer for the inverter when using the inverter. *The result is: the inverter moves together ...

1. Be "confident" It is necessary to fully understand the principles of some typical circuits and be familiar with them. Guangzhou Kewo Training Center believes that drawings are dead, and the thoughts in the head are alive, able to make analogies, able to reason, and able to touch analogies. For example, switching power supply is always inseparable from ...

1. Manually operate the work stop button of the inverter panel, investigate the work stop process of the motor and the display window of the inverter to see if there is any abnormal phenomenon. 2. If the inverter presents an overcurrent maintenance action during the process of starting P to abort the motor, ...

The inverter mainly has the following functions: 1. Soft up The direct launch of the inverter motor will have a severe impact on the power grid, and it will also have too high requirements for the capacity of the power grid, which is extremely unfavorable to the service life of equipment and power grid circuits.

1. Power-related products: medium, low and high voltage electrical products; (1) Low Voltage Products: Molded Case Circuit Breaker, Air Circuit Breaker, LS Contactor & Overload Relay, Miniature Circuit Breaker, Dual Power Automatic Transfer Switch, Intelligent Motor Protector, Manual Motor Starter, Surge Protection ...

One. Logical stage　　 The so-called logical stage is to be able to complete the general logical planning in the relay system, since it is a relay system, so the knowledge of power drag is the foundation of this stage. I personally summarize that the root of learning the relay system lies in the word "grab", the relay system ...

Rated current of LS molded case circuit breaker: Now in the process of using the molded case circuit breaker, it is necessary to understand the rated current of the molded case circuit breaker, and the rated current of the molded case circuit breaker is generally more than a dozen, mainly 16A...

1. The influence of electromagnetic disturbance on the inverter: In the modern industrial control system, the microcomputer or PLC control technology is mostly selected, and in the process of system planning or transformation, it is necessary to pay attention to the disturbance of the inverter to the microcomputer control board. The inverter is disturbed by the outside world, because the user ...

In March 2019, LS Group signed a strategic cooperation agreement with Country Garden to build Cisco Smart City into an innovative model for smart cities. LS Electric will provide power distribution system solutions for Cisco (Guangzhou) Smart City, providing frame circuit breakers, molded case circuit breakers, vacuum circuit breakers, miniature circuit breakers, and micro circuit breakers.

First, the frequency conversion skill is only one of the many power-saving skills, including voltage regulation and current limiting, power factor compensation, phased power regulation, frequency conversion, chopping, filtering, energy feedback and other skills, even if the power saver using the principle of frequency conversion is concerned, the frequency converter is only power-saving.

1. The main reason for the overload of the inverter (1) Malfunction, the current detection part inside the inverter has a problem, and the detected current signal is too large, resulting in tripping. (2) The mechanical load is overloaded, and the main feature of the overload is that the motor heats up, and it can be ...

From the point of view of application, the function that should be reached is: it is necessary to conduct the local area where the touch part should be conducted, and the touch is reliable. If the insulating part should not be conducted, it is necessary to insulate it firmly. There are three common types of faults in terminal blocks: ...

The basic components of PLC for power production: 1. Memory 　　​ 　　The memory that registers the architecture software is called the architecture program memory. The memory that registers the application software is called the user program memory. 2. Power supply ...

1. As soon as the inverter of the heat exchange station is opened, the pressure transmitter jumps randomly; 2. Use the inverter to control the water supply, the pressure transformer is used as the signal to collect the pressure, and the pressure transformer is disturbed by the inverter; 3. When the inverter starts the motor, the voltage converter signal is unstable and beats violently; 4. Pressure transformer (4-20 ...

In fact, the fault of the motor is not the cause of the motor itself, most of them are caused by the non-standard debugging of the inverter or the wrong inverter motor when the inverter motor is used, etc., mainly in the following situations: 1. Treat the general motor as a ...

1. Problem phenomenon: servo error OL, servo motor can not start, and there is abnormal sound problem analysis and possible causes: (1) Bearing damage, foreign objects falling and stuck, stator magnet bursting and falling or moving tissue jamming caused by the motor itself. (2) ...
