Electrical complete equipment is the basic equipment of equipment manufacturing industry, which has a wide range of applications in all walks of life of the national economy and people's livelihood. Since 1980, China's reform and opening-up policy has led to rapid development of the national economy and increased investment in economic construction, especially in infrastructure and electric energy, which has greatly stimulated the development of the industry. Based on the introduction of foreign products, China has gradually acquired the ability to design and develop complete sets of electrical equipment. Since the 1990s, international famous electrical brands began to invest in China to build factories and joint ventures, which greatly promoted the development of new products and the improvement of manufacturing technology level of domestic enterprises.

With the development of infrastructure construction and power energy investment, the demand for complete electrical equipment in China is increasing year by year, the speed of product upgrading is accelerating, the number of models is increasing, the technical performance has been significantly improved, and the production equipment and processing technology have been significantly improved. With higher cost performance and service advantages than foreign similar products, domestic brands have occupied a dominant position in the domestic market competition.

The market demand of complete electrical equipment is broad

One of the main applications of electrical complete equipment is the control and protection of power system, so the power industry is the direct consumer industry of electrical complete equipment. The investment and development of the power industry directly affect the market demand of the electrical complete equipment industry. In recent years, our government has increased investment in the technical transformation of power grid, especially smart grid, West to East power transmission, national networking, rural power grid transformation and urban power grid transformation involved in the development of urbanization, which has played a positive role in promoting the electrical complete equipment manufacturing industry. In addition, with the acceleration of China's industrialization process, it will also promote the growth of the demand for complete electrical equipment, especially the pillar industries of the national economy such as petroleum and petrochemical, iron and steel metallurgy.

During the "12th Five Year Plan" period, power investment has increased significantly, and the demand for complete electrical equipment is broad

With the continuous advancement of industrialization and urbanization in China, the demand of power industry will keep growing. According to the data disclosed by China Electric Power Enterprise Federation in the 12th Five Year Plan Research Report of electric power industry, in the next 10 years, China's total investment in electric power industry will reach 11.1 trillion yuan, of which, during the 12th Five Year Plan period, the national investment in electric power industry will reach 5.3 trillion yuan, an increase of 68% over the 11th Five Year Plan period.

According to the statistics of China Federation of electric power enterprises: in 2010, China's electric power scale continued to expand, with the installed power generation capacity reaching 966 million kilowatts, a year-on-year increase of 10.56%. At present, China's per capita installed capacity is only 0.6-0.7kw, which is far from 1-3kw per capita in developed countries. China plans to achieve a total installed capacity of more than 1.878 billion in 2020, so China will add more than 900 million KW.

The continuous high-speed growth of industrial enterprises has greatly stimulated the demand space of complete electrical equipment

At present, China is still a developing country, and industrial development is still the main driving force of China's economic growth and the key area of development. It is expected that it will continue to grow for quite a long time in the future, which undoubtedly provides a guarantee for the continuous growth of complete electrical equipment.

According to the "Twelfth Five Year Plan" development guide for petroleum and chemical industry released on May 27, 2011, during the "Twelfth Five Year Plan", the average annual growth rate of the industry will be maintained at more than 10%. By 2015, the total output value of the industry will reach 16 trillion yuan, which will greatly drive the high-speed growth of intelligent electrical complete sets of equipment. It is mainly reflected as follows: first, the demand space provided by new production capacity will continue to increase; second, the demand space provided by new production capacity will continue to increase; Second, due to the increase of total capacity, the space provided for regular replacement of equipment continues to increase.

With the rapid development of China's metallurgical industry and the rapid expansion of steel production capacity, the output increased from 140 million tons in 2001 to 620 million tons in 2010, with an average annual increase of about 50 million tons. With the expansion of the capacity of China's metallurgical industry, it will inevitably lead to the growth of the demand for electrical equipment, resulting in the growth of the output of complete electrical equipment.

Intelligent development trend of complete electrical equipment

During the 12th Five Year Plan period, with the development of strong smart grid, the construction of strong smart grid requires the equipment to have the functions of digitization, informatization and online detection, and the intelligent development of complete electrical equipment will be the focus. In recent years, with the development of computer technology, data processing technology, information sensor technology, communication and data storage technology, power electronics technology and the integration of various disciplines, the intellectualization of complete electrical equipment has gradually become an important trend in the development of the industry. Intelligent complete sets of equipment make the protection, control, monitoring and measurement of the whole transmission and distribution system centralized, realize the automation of distribution network, lay the foundation for wide area monitoring and diagnosis system, and ensure the safe, reliable and economic operation of power system.

The intelligent upgrading of distribution network greatly increases the intelligent upgrading of complete electrical equipment

At present, the infrastructure construction of distribution network is the weakest among all levels of power grid in China. Due to insufficient investment in distribution network, aging equipment and poor technical performance, high energy consumption equipment and high power loss rate, the loss of distribution network in general areas is 15% - 20%, and that in some areas is 30%, resulting in a lot of energy waste and environmental pollution, especially in rural power grid.

In view of the above situation, the state has issued some special policies to guide. At present, the policy mainly focuses on rural power grid transformation. In 2011, the national development and Reform Commission issued the "opinions on the implementation of a new round of rural power grid transformation and upgrading project" and the "technical principles for rural power grid transformation and upgrading" issued by the national energy administration, respectively pointing out that the new round of rural power grid transformation and upgrading project is "intelligent upgrading" during the "Twelfth Five Year Plan" period, focusing on the development of new energy decentralized access, power distribution automation, power distribution automation, power distribution automation, etc Intelligent distribution station area, rural power information collection and other pilot construction.

The information construction of industrial enterprises is in full swing, deepening the intelligent upgrading and transformation of complete electrical equipment

China's information construction is gradually becoming mature, and its application is developing from high-end markets such as petroleum, petrochemical, steel and so on to a diversified direction. It has a very wide application prospect in tobacco, pharmaceutical, paper and food industries. The information construction will drive the demand of intelligent upgrade and replacement of electrical equipment.

Taking the metallurgical industry as an example, the guiding opinions of the Ministry of industry and information technology on energy conservation and emission reduction of iron and steel industry emphasizes: "before 2011, we will focus on supporting iron and steel enterprises with more than 3 million tons to build or transform energy management centers, support the promotion and use of digital measuring instruments in iron and steel enterprises, actively apply electronic information technology, and implement dynamic monitoring of energy transmission and consumption Control and optimize the management, and constantly strengthen the balance, scheduling, analysis and prediction of energy to achieve systematic energy saving and consumption reduction. With the gradual release of the state in the metallurgical industry, the equipment with poor quality and high energy consumption will be eliminated, and energy saving and high efficiency will be vigorously promoted

In the future, the metallurgical electrical equipment will develop in the direction of intelligence, automation, energy saving and so on, which will also promote the upgrading of electrical equipment.
