Power electronic devices determine the development level of VFD (Variable-frequency Drive) industry

For a long time, the industrial field has been the focus of energy conservation and emission reduction. In today's rising energy costs, the development and promotion of power electronic devices is an important technical means to achieve high efficiency and energy saving in industry. We can see that with the continuous breakthroughs in the development of power electronics technology, industrial automation products are not only becoming smaller and more flexible in size, but also the energy efficiency of the overall system has been greatly improved, especially in terms of reducing energy consumption. Significant progress has been made.

In the context of rapid economic development in the past few years, China has become the world's largest power electronics market. In the future, this development trend will continue unabated. Projects such as infrastructure construction, power grid transformation, new energy industry development, and electric vehicles that the government is vigorously promoting will bring greater development space for power electronics.

Similarly, power electronic devices also determine the development level of the entire VFD (Variable-frequency Drive) industry. VFD (Variable-frequency Drive) products, which are energy-saving tools, are optimized by using more advanced power electronic devices, which also help users maximize energy-saving technologies in practical applications. Power devices IGBT and electrolytic capacitors are the two main power electronic devices used in VFD (Variable-frequency Drive). From the perspective of the cost structure of VFD (Variable-frequency Drive), the sum of the two costs accounts for 10% of the total cost of medium and low voltage VFD (Variable-frequency Drive). -frequency Drive) costs nearly 40%, and in high-voltage VFD (Variable-frequency Drive), the proportion of power electronic components such as IGBT is as high as 50%.

Since it is an important component in the VFD (Variable-frequency Drive) product composition, VFD (Variable-frequency Drive) manufacturers are very cautious in purchasing and selecting power electronic components. Today, with the ever-changing power electronics technology, how can VFD (Variable-frequency Drive) manufacturers keep up with the pace of power electronics devices and improve the application level of power electronics technology? We Media hopes to serve as a bridge with many excellent power electronics manufacturers at home and abroad. The cooperation alliance will jointly build a new platform for Chinese VFD (Variable-frequency Drive) industry chain -- a display platform for power electronics comprehensive solutions, focusing on displaying power electronic devices used in VFD (Variable-frequency Drive), including power supplies, resistors, A wide range of products from electrolytic capacitors to IGBTs. By means of this cooperation: to jointly disseminate advanced power electronics technology at home and abroad, to enhance the corporate brand image, and to provide convenient product selection and procurement services for many VFD (Variable-frequency Drive) manufacturers.

According to the latest data, Chinese Manufacturing Purchasing Managers Index (PMI) in July was 50.3%, a slight increase of 0.2 percentage points from the previous month. , the strengthening of urban infrastructure construction, and the blowout railway planning in the second half of the year will become the three most noteworthy good news recently.

Railway construction may restart construction machinery to speed up

The impact of railway construction on the construction machinery industry is obvious. Although there are constant rumors about accelerating railway construction, the plan to restart railway construction on a large scale was not settled until after the State Council executive meeting held on July 24. The meeting studied and deployed the reform of the railway investment and financing system and further accelerated the construction of railways in the central and western regions. According to the State Council's plan, this year's railway fixed asset investment will be raised from 650 billion yuan planned at the beginning of the year to 690 billion yuan, and a total investment of 1.4 trillion yuan will be completed in the next two years. At the same time, the number of newly started projects in 2013 was adjusted from 37 to 47.

At the same time, the executive meeting of the State Council clearly pointed out that it is necessary to "raise construction funds in multiple ways and channels, guide by the central financial funds, attract social capital investment, establish a railway development fund, and innovate the types and methods of railway bond issuance. To local and social capital Open the ownership and management rights of intercity railways, urban (suburban) railways, and resource development railways.” It is reported that the railway investment and financing system reform plan will be reported to the State Council before the end of September, and is expected to be introduced by the end of this year.

Urban infrastructure assistance: one of the important factors driving the development of construction machinery

Infrastructure construction has always been one of the most important factors driving the development of the construction machinery market. In 2008, the 4 trillion yuan economic stimulus plan launched by the State Council almost caused a qualitative change in Chinese construction machinery market. Most of the projects are based on transportation infrastructure. as the main direction of investment. It is almost certain that Chinese construction machinery market will usher in a new period of rapid development, but after experiencing the "four trillion" pains, the construction machinery industry will usher in a more rational development.

Premier Li Keqiang of the State Council presided over an executive meeting of the State Council on July 31 to study and promote the government to purchase public services from social forces and deploy and strengthen urban infrastructure construction. The meeting determined the following key tasks: First, strengthen the construction and renovation of municipal underground pipe networks. Improve urban water supply facilities and enhance urban waterlogging prevention capabilities. The second is to strengthen the construction of sewage and domestic waste treatment and recycling facilities. By the end of the "Twelfth Five-Year Plan", the harmless treatment rates of urban sewage and domestic waste will reach about 85% and 90% respectively. The third is to strengthen the transformation of old gas and heating pipe networks. By 2015, 80,000 kilometers of urban gas and nearly 100,000 kilometers of central heating in northern heating areas will be completed. The fourth is to strengthen the construction of large-capacity public transportation systems such as subways and light rails, and enhance the connectivity, accessibility, and convenience of urban road networks. Accelerate the construction of walking and cycling "greenways" in cities across the country. Do a good job in the safety inspection and reinforcement of urban bridges to ensure traffic safety. The fifth is to strengthen the construction of urban distribution networks and promote the intelligentization of power grids. The sixth is to strengthen the construction of the ecological environment, improve the functions of urban green spaces for flood storage and drainage, and replenish groundwater.

Reform of camp to increase: promote the separation of main and auxiliary construction machinery enterprises

Starting from August 1, the pilot program of replacing business tax with value-added tax, known as the "highlight" of Chinese tax reform, was officially launched nationwide. The scope of the pilot program of replacing business tax with VAT in the transportation industry and some modern service industries will be expanded from the current 12 provinces and cities to the whole country. , which marks the gradual deepening of the reform of the business tax reform, realizing the "double expansion" of regions and industries, and further intensifying the reform.

The main role of the camp reform is to avoid double taxation and reduce the burden on enterprises. This reform will have a profound impact on economic development. It will also be of great strategic significance to promote the adjustment of economic structure and the transformation of economic development mode.

In order to reduce operating costs, many construction machinery companies have to tie up auxiliary businesses such as logistics and information while doing a good job in their main business, which increases the operating pressure of the company. For the construction machinery industry, the reform of business tax to VAT will bring about a huge "spillover effect". After the auxiliary business is responsible for its own profits and losses, it may generate greater vitality. By promoting the development of the service industry, especially the modern service industry, the "replacement of business tax with value-added tax" accelerates the separation of main and auxiliary construction machinery enterprises, changes the "olive-shaped" corporate structure of existing construction machinery enterprises into a "dumbbell-shaped" enterprise structure, and adds value by opening up the secondary and tertiary industries tax credit chain,
