After years of development, China's low-voltage electrical industry has formed a relatively complete system. It can produce nearly 1000 series of low-voltage electrical products with an output value of about 30 billion yuan. Due to the large number of enterprises, especially the rise of a large number of private enterprises in Wenzhou, the formation of an absolute buyer's market has resulted in a serious overcapacity of more than 50%. China's low-voltage electrical appliance manufacturing enterprises are mainly concentrated in Beijing, Tianjin, Liaoning, Shanghai, Jiangsu, Zhejiang and Guangdong. The distribution of enterprises is generally reasonable. There are several problems in the economic scale of enterprises: (1) The scale of the organization is small and scattered, lacking competitive strength and advantages. At present, there are not many manufacturers of low-voltage electrical appliances entering China's large-scale enterprises, while SMEs account for more than 90% (large-scale enterprises with annual sales income and total assets of 500 million yuan or more; medium-sized enterprises with 50 million yuan or more) Enterprises, the rest are small businesses); (2) The regional structure is convergent and cannot reflect comparative advantages and synergistic benefits. In the 20 years since the 1980s, the number of low-voltage electrical appliances has increased from more than 600 to more than 1,000 now. Due to blind projects and paving, the regional industry has become more and more accommodative, with low economic returns and low-level redundant construction, resulting in product backlog, energy, material waste, and low economic consequences. (3) The technical structure is unreasonable, and the level of technical equipment in major industries is low. According to statistics, in the main technical equipment of enterprises, the technical and economic performance is only one third of the advanced. The leading products of the backbone enterprises accounted for only about 18% of the international technical level in the 1990s. In 2011, China's electric power infrastructure will continue to maintain a large investment scale. The newly installed infrastructure of the country's infrastructure will be about 90 million kilowatts. At the end of the year, the installed capacity of the country will exceed 1.04 billion kilowatts. The production of so many power generation equipment will inevitably require corresponding low-voltage electrical components. In addition, a new round of rural power grid reconstruction and upgrading projects, and a new investment of 300 billion yuan in rural power grid transformation in the next three years, is a great opportunity for the future expansion of the low-voltage electrical industry. The key is to see whether the company can cater to the urgently needed products in the market, as well as product quality stability and operational reliability. Judging from the survey of major enterprises in the industry, the sales value of the second half of the year is optimistic. It is estimated that the overall sales of low-voltage electrical appliances in 2011 will continue to grow compared with 2010, about 45 billion yuan. Corporate profits will also be in a steady and modest growth. In 2011, the smart grid will enter a full implementation phase, with a total investment scale of nearly 4 trillion yuan. These have once again demonstrated the determination and will of the Chinese government to make rational use of resources, vigorously promote energy conservation and emission reduction, and actively develop a low-carbon economy. At the same time, investment in power grid construction will also enter a period of rapid growth, and the long-term development potential of the primary equipment sub-sector and secondary equipment sub-sector is huge. Therefore, industry enterprises must firmly grasp the development opportunities of smart grids, and with the development of smart grids, enterprises must clearly realize that the development of low-voltage electrical appliances should first be considered from the perspective of system development. And we must work hard from the system to all power distribution, protection, control components, from the power to the weak power. The development of low-voltage electrical products in the future will present the following development trends: Low-voltage electrical products are intelligent. In modern power stations and industrial and mining enterprises, electronic computer monitoring systems have been widely used, and high-performance and intelligent requirements for low-voltage circuit breakers are provided, and products are required to have protection, monitoring, testing, self-diagnosis, display, etc. Features. Electronic products. In modern enterprises, the use of PC control systems instead of systems consisting of electrical-mechanical components is the mainstream of mechanical and electrical control systems. The system requires electrical products with high reliability and high anti-interference. It also requires that the contacts can reliably connect low voltage and weak current. The arc when the contacts are disconnected cannot interfere with the normal operation of the electronic circuit. Product combination and modularization. Combining modules with different functions into modular combination appliances according to different requirements is the development direction of the low-voltage electrical industry today. Adding auxiliary contact components, delay components, self-locking components, interface components, mechanical interlocking components and surge voltage components to the body of the contactor can adapt to the requirements of different occasions, thereby expanding the scope of application and simplifying the production process. It is convenient for users to install, use and repair. At the same time, product reliability and product quality will be further improved.
