Inverter repair cleverly replaces inverter parts

With the conclusion of the 19th National Congress of the Communist Party of China, the spirit of the major conferences has been newly conveyed. Among them, General Secretary Xi Jinping said that in order to practice the concept of green development, we must establish and practice the concept that lucid waters and lush mountains are invaluable assets, and to protect the ecological environment is to protect productivity, and to improve the ecological environment is to develop the ecological environment.

What kind of flowmeter can be used to measure the quantitative controller of diesel flowmeter, and how to measure it? A: Diesel flow quantitative metering, which can be performed using the flow quantitative control cabinet system, while diesel flow measurement, which can be measured using ultrasonic flow meter, ultrasonic flow meter, measurement precision ...

In the field, the interference of the frequency converter is more frequent and more serious, and even causes the control system to be unable to be put into use. The operating principle of the inverter is destined to produce strong electromagnetic interference. The inverter includes a rectifier circuit and an inverter circuit, and the input alternating current passes through the rectifier circuit and the flat wave.

1. Application and development of magnetic flap level gauge in liquid chlorine tank level detection Liquid chlorine is a high-risk and highly toxic substance, which is highly corrosive, and once it causes leakage, it will cause great harm to the environment and the human body, so it is particularly important to ensure the safe operation of the liquid chlorine tank. And accurate and reliable control ...

The Semiconductor Industry Association (SIA) recently announced that global semiconductor sales in June 2017 reached $32.6 billion, up 2.0% compared with the previous month; This is a 23.7% surge compared to the same period last year. Semiconductor sales in the second quarter of this year were US$97.9 billion, up 5.8% quarter-on-quarter and 23.7% year-on-year; This year...

Because the waters are intersected and connected, the waste discharged by each country and region is concentrated in the deep sea, and marine garbage has long become a global problem. Most of the marine debris is concentrated in five untouched areas, each of which falls in the Pacific Ocean of China, which is larger than the ...

1. Ground the ground terminal of the inverter. 2. Connect the power input terminal of the inverter to the power supply through the leakage protection switch. 3. Check whether the factory display of the inverter display window is normal, if it is incorrect, it should be changed to reset the operation, if it is still incorrect, it should be returned. ...

1. Why is the leakage circuit breaker easy to trip when using the inverter? This is because the output waveform of the inverter contains higher harmonics, and the motor and the cable between the inverter and the motor will generate a leakage current, which is much larger than that when the motor is driven by the power frequency. ...

After the inverter runs uninterrupted for a long time, the high temperature generated inside has serious hidden dangers to the operation of the inverter, especially in summer. The ultimate operating temperature of the inverter inside the inverter is generally 125 °C, and the temperature of the inverter inverter module and IGBT can sometimes reach 110 °C.

The flow meter is one of the important instruments in the water, petrochemical and other industries, which can be compared with the eye of measurement. For the water conservancy industry, it is of special significance. For example, the addition of chemicals in the water supply industry, if the accuracy of the relevant metering instrument is not high, it will directly affect the quality of water quality.

Shanghai has issued a red high temperature warning for several days, and the temperature of 40.9°C has tied the highest record since 1873. The root cause of the continuous high temperature and heat wave events in many places in the northern hemisphere is believed to be the global warming trend. Global warming is happening at an unprecedented rate, and several ...

Since the advent of automatic induction motors, variable frequency operation has existed in the form of alternators. Change the rotational speed of the generator, and change its output frequency. Before the advent of high-speed transistors, this was one of the main ways to change the speed of the motor, but due to the generator speed ...

Ultrasonic level gauge is a non-contact instrument that uses the principle of echo ranging. The echo ranging principle is also known as the travel time or travel time measurement principle. It emits energy waves through a device that can emit energy waves (generally pulse signals), and the energy waves are reflected when they encounter obstacles, and are reflected by a ...

The measurement of urban pipe network flow is an important task of water supply enterprises in pipe network management. In the past few years, our company has used Japan Fuji portable ultrasonic flowmeter to measure water consumption for large water users, and persuaded and alleviated the "supply and demand" contradiction between these enterprises and companies with scientific data; Especially...

The cause of the leakage problem We all know that the three-phase stator winding of the motor flows through the current to produce a rotating magnetic field, according to the principle of magnetoelectric induction, the shell of the motor will produce an induced electromotive force, the size of this electromotive force depends on the size of the switching frequency of the inverter IGBT, due to the high ...

Fuji Electric Corporation (Headquarters: Shinagawa-ku, Tokyo, President: Tsuhiro Kitazawa) has released the MONITOUCH X1 Series programmable operation display. With Windows*, you can collect information from the field to manage your work with just one monitor.

Due to the outstanding technical application advantages of Fujifilm ultrasonic flowmeter, Fujifilm ultrasonic flowmeter has been widely concerned in various fields such as power plant flow measurement, which can be reflected from the following application cases. Circulating water flow is measured in hydropower plants ...

On March 16, 19, Fuji Electric Power Semiconductor Symposium was held in Guangzhou. More than 90 customers and agents from all over the country were invited. Fuji Electric looks forward to carrying out in-depth communication with you according to the publicity and education content of this seminar, so that everyone can have a good understanding of Fuji Electric.
