Intelligentization will become the future trend of low-voltage electrical applia

date: 2022-11-25

  The market capacity of low-voltage electrical appliances industry is closely related to the development of power industry. The rapid development of domestic power grid construction has brought broad space for the development of low-voltage electrical appliances industry. According to the corresponding power distribution equipment required by the new power generation equipment during the "Eleventh Five Year Plan" period and the need for replacement and maintenance of existing power equipment, it is estimated that the demand for universal circuit breakers, plastic case circuit breakers, small circuit breakers, AC contactors, thermal relays, leakage circuit breakers and other products will reach more than 200 million. In recent years, the low-voltage electrical appliance industry has continued to develop rapidly, with active import and export trade and substantial growth in quantity. In 2008, the import and export volume of low-voltage electrical appliances reached more than 18 billion US dollars, of which the export volume reached 8 billion US dollars. In the first half of 2009, the export volume reached 4.79 billion US dollars, an increase of 35%% over the same period, and will grow at a rate of nearly 30%%.

  Experts predict that in the near future, China will not only become a major producer of low-voltage electrical appliances, but also a major exporter. The research and development of high-end products will still be the main direction of the industry in the future. The market potential is huge. After more than 50 years of development, the low-voltage electrical appliance industry has formed a relatively complete industrial system. Its products have a wide range of uses and a huge market potential. Industry statistics show that there are about 1000 series of domestic low-voltage electrical appliances, with an output value of 20 billion yuan, and more than 2000 enterprises above designated size. At present, low-voltage electrical appliances are at the technical level of the first generation to the third generation, and the fourth generation products are still under development. With the improvement of domestic electric power construction level and the continuous development of low-voltage apparatus production technology, a new generation of low-voltage apparatus featuring intelligence and communication will become a high-end product. The first generation products will be withdrawn from the market in 2010, the second generation products will become low-grade products, and the third generation products and some second generation products will be classified as mid-range products.

  At present, the domestic medium and low-grade low-voltage electrical appliances basically occupy most of the domestic market, but the domestic high-end low-voltage electrical appliances are still very low in the domestic market, with the exception of a few products that can equal the foreign similar products. The domestic market demand for high-end low-voltage electrical appliances mainly depends on imports. It is estimated that during the 11th Five Year Plan period, the import of high-end low-voltage electrical appliances will continue to grow rapidly. According to relevant planning, at the end of the 11th Five Year Plan period, the installed capacity of domestic power generation will be close to 800 million kilowatts. By 2020, the installed capacity of domestic generators will reach 1.186 billion kilowatts, surpassing the United States and ranking first in the world. There is a huge market space for low-voltage electrical appliances. The development of low-voltage electrical appliances presents several characteristics: intellectualization. In modern power stations and industrial and mining enterprises, electronic computer monitoring systems have been widely used. The requirements for high performance and intelligence of the matching low-voltage circuit breakers are put forward, and the products are required to have the functions of protection, monitoring, testing, self diagnosis, display, etc.
