The low-voltage inverter market has declined slightly and the market concentration has declined. In addition to the two major brands, ABB and Siemens, accounting for 21% of the market, the market share of 3-10 is similar, and the share of foreign brands in the domestic inverter market remains at 60% - 70%.Although domestic brands are on the rise this year
With the development of China's economy, Shanghai Auto Show has become more and more important, and has the momentum of becoming an important auto show in the world.This auto show is different from previous ones. Both Chinese and foreign manufacturers have launched a large number of new energy models.German media even said that this year's Shanghai Auto Show is a plug-in hybrid vehicle
The application and development trend of AC variable frequency speed regulation in rail transit traction system The rapid development of electrified railway and urban rail transit from DC to AC drive is the development of emerging power electronic devices.The rapid development of electrified railway and urban rail transit from DC to AC drive is an emerging power electronics
Frequency converter is a power control device that converts power frequency power supply to another frequency by using the on-off action of power semiconductor devices.The main circuit of frequency converter can be generally divided into two types: voltage type is the frequency converter that converts the DC of voltage source into AC, and the filter of DC circuit is capacitor;Current mode is to convert the DC of current source into
1、 The problem is that the programmable controller technology zui is mainly used in automation control engineering, how to comprehensively use the knowledge points previously learned to reasonably combine the control system according to the actual engineering requirements, and the general method of forming the programmable controller control system is introduced here.2、 PLC control system settings

2 Introduction With the development of the national economy and the improvement of people's living standards, people are paying more and more attention to the improvement and beautification of the living environment. The music fountain system has become an important part of the urban landscape construction with the combination of sound, light, water and color. Large and medium-sized cities in China have been competing to build music fountains and develop to small cities
Introduction Since the machining range of the machine tool is wide, different workpieces, different processes, and different tools are used, the executing parts of the machine tool are required to have different motion speeds, so the main motion of the machine tool should be able to speed up, and the machine tool users pay more attention to the speed adjustment function of the inverter products.Spindle is an important part of lathe
Frequency converter is a common electrical equipment of Zui in the automation factory. Let's take a look at the common fault phenomena of frequency converter Zui and analyze and deal with examples.1、 Over current (OC) Over current is a frequent phenomenon of frequency converter alarm zui.1.1 Phenomenon (1) When restarting, it will trip as soon as the speed is increased.Yes
