The twenty-first Century China, technology, economy and standardization of the increasingly close ties, there is a close relationship between the development of different global standards and technology progress and the development of production, which ensure the versatility and interchangeability. Development of technology and economy, but also promoted the change and development of standardization, standardization in the world of technology and economic life is becoming more and more important in.

 

The modern standard reflects the enterprise and the market demand, all kinds of professional and technical standards has become the technology according to the enterprise production, inspection of products, but also all other products import restrictions and important basis of setting technical barriers. With China's accession to the WTO and the acceleration of economic globalization, technology development, standards in enhancing the competitiveness of Chinese products in the world, play a decisive role in the promotion of international trade and the reasonable protection in China market.

 

Low-voltage electrical appliances are basic components of machinery industry, the product performance and quality directly affect the reliable operation of power systems and industrial control system. Low-voltage electrical industry as a basic industry of the national economy, is an important part of the national economy. According to statistics, more than 80% of the electrical energy is through the low-voltage electrical distribution to electrical equipment use. With the construction of smart grid in China, electrical components, low-voltage electrical appliances as the essential client distribution network, will play a more important role.

 

One, current situation and characteristics of low-voltage electrical industry

 

Low-voltage electrical appliance is used for AC voltage to 1000V, on and off, the control and protection of electrical circuits for 1500V DC voltage to the low voltage system, distribution, control and protection circuit and electric equipment important electronic components. Low voltage power distribution system is mainly composed of various low-voltage electrical components complete switch equipment, function and performance of low-voltage electrical appliance component determines the complete sets of equipment performance and reliability. According to statistics, an increase of 10000 per kW power equipment, about 40000 pieces around various low-voltage electrical components and supporting. In industrial automation system, needs various kinds of control equipment is composed of low-voltage electrical protection and control.

 

Low-voltage electrical industry production in China is more dispersed, the production of more than 1500 enterprises, more medium and small enterprises, uneven level of enterprise technology, system supporting ability is poor. Because the product is mostly composed of unified design after the transfer of technology to promote the production, so the product homogeneity serious, enterprise characteristic products. Yield though huge, but our country compared with developed countries is still a manufacturing power rather than power. Electric power industry in China is still in the development stage, the low-voltage electrical demand is still growing, according to experience of supporting capacity and electrical components of the ratio calculation, annual need of low-voltage frame breaker about 480000 Taiwan, molded case circuit breaker type 4820000, other types of low-voltage electrical products demand is also very impressive. Predictably, the market capacity of low-voltage electrical appliances in China will steadily increase.

 

Two, low-voltage electrical standardization

 

1 low-voltage electrical standard system

 

China's low-voltage electrical industry after 50 years of development, from the enterprise, product standards, testing, has formed a relatively complete system. China's low voltage standard system based on the IEC (International Electrotechnical Commission) system is established, in the last century 90's has been completed in line with the IEC standard. Low-voltage electrical appliances national standard basic equivalent, modify the use of international standards and advanced foreign standards, combined with the actual situation in China, such as the geographical environment difference, technology development and application of such factors as the development of a number of independent innovation, comply with the technical standards of China's development. At present, China's low-voltage electrical industry a total of 62 national standards, industry standards 38, announced the implementation of these standards, to provide design, production and certification of the basis for the enterprise, can better meet the demands of the market and the development of the national economy.

The conditions of the existing professional and Technical Committee

 

China's low-voltage electrical industry currently has 4 national technology standard and 1 Technical Committee, the Secretariat is located in Shanghai Electrical Apparatus Research Institute (Group) Co. Ltd. (referred to as the application).

 

The Technical Committee on international standards and participate, product and technology development dynamic research and the dissemination of national standards, industry standards revision, the standard implementation, supervision, technical consultation plays a huge role. On the branch, as the Board Secretariat unit commitment, long-term commitment to the low-voltage electrical standardization work in our country, the existing more than national standards and industry standards, the vast majority of the branch, responsible for the preparation and revision, and leading the development of China's low-voltage electrical industry in domestic and international standardization research, technical innovation, production product research and development, in the industry has a very high prestige.

Opportunities and challenges of the 3 low-voltage electrical standardization

 

China's smart grid construction has brought new technology and market demand for low-voltage electrical appliances, low-voltage electrical appliances are faced with good market prospects. But the market competition will be more intense, foreign almost all low-voltage electrical Multi-National Corporation have entered China's increased competition in the domestic market; foreign start all kinds of technical barriers to restrict China's export products; raw material prices make the product costs continue to increase. Low-voltage electrical standard for the future.
