Low voltage circuit breaker (once called automatic switch) is a switching device that can not only connect and break off normal load current and overload current, but also connect and break short circuit current. In addition to controlling the circuit, the low voltage circuit breaker also has some protective functions, such as overload, short circuit, under voltage and leakage protection.

The market for low voltage circuit breakers has experienced a good growth in 2011. With the construction of smart grid and the development of the new energy industry, a stable growth will be maintained in the next few years. It is mainly manifested in the following aspects: 　　

(1) new demand arising from large-scale deployment of smart grid

The construction of smart grid is implemented in three stages before 2020. The first stage is 2009-2011 years, mainly research and pilot, the second stage is 2011-2015 years, the smart grid will be implemented on a large scale, the third stage is 2016-2020 years, and the overall improvement and promotion will be achieved.

At present, the national Power Grid Corp is stepping up the development of nearly 200 smart grid technology standards in China. With the introduction of planning and standards, the construction of smart grid will enter the itinerary, which will bring huge demand to medium and high end low voltage circuit breakers. 　　

(2) the investment in the manufacturing industry drives the future growth

The manufacturing industry is the key application field of low voltage electrical apparatus industry, and it is also one of the ten key engineering fields of energy saving and emission reduction. Due to the pressure of energy-saving targets, China's manufacturing industry will maintain strong demand for energy-saving control and intelligent distribution electrical products. 　　

(3) wind, solar and other new energy demand for medium and high-end low-voltage circuit breakers.

New energy investment has become the focus of attention after the Copenhagen conference. The new energy and low carbon economy has become the main direction of the electrical equipment industry. The vigorous development of new energy will create a large demand for efficient, stable medium and high-end low-voltage electrical products. Demand for low-voltage electrical components is expected to increase substantially in 3-5 years. A batch of core and key technologies such as wind power generation and photovoltaic power generation inverter control system and grid connected technology need to be broken through. This is also a direction for the development of low voltage electrical appliances industry in the future.

Statistics show that the market scale of China's low voltage circuit breakers in 2011 was 40 billion yuan. In the next few years, with the growth of new electric power increasing and the rapid development of other industries in the next few years, the demand for low voltage circuit breakers in domestic market will continue to grow, so the market size of the low voltage circuit breaker in China will also increase rapidly. It is expected that the market size of our low voltage circuit breaker industry will be close to 8 by 2016. 00 billion yuan.

From the end of twentieth Century to the beginning of twenty-first Century, a new type of ACB and MCCB have been introduced and improved and expanded. No matter in the main technical performance, the product structure, the new technology application and so on, there are major breakthroughs and innovations. Among them, Germany SIEMENS is the most prominent, the communication of low voltage electrical appliances, can form a very large industrial system, power distribution monitoring system and building automation system; the MDU series of circuit breakers developed by the Mitsubishi Co, can directly realize the power energy monitoring network system, equipment monitoring network system and so on.

Low voltage appliances are widely used in various sectors of the national economy and are closely related to fixed investment in the whole society. 21 the initial stage is the rapid development stage of China's low-voltage electrical appliance industry. The growth rate of low-voltage electrical appliances industry in China has been maintained at 10%-15% in recent years. The market capacity of low voltage electrical appliances industry is closely connected with the development of electric power, industry, real estate, telecommunication industry. The demand structure of low voltage electrical appliances and the potential demand of international market provide a broad space for the future development of low voltage electrical appliances industry.

In the 12th Five-Year, with the development of smart grid construction and the continuous development of low voltage electrical production technology, the new generation of low-voltage electrical appliances, which are intelligent, modularized and communicable, will become the mainstream products in the market. The first generation of products will be withdrawn from the market in 2010. The second generation products will become low-end products, and the third generation products and some second generation products will become the mid end products. From 2011 to 2015, the smart grid will enter the comprehensive construction stage in seven aspects of transmission, transformation, distribution, communication and so on.
