Is a low-voltage electrical signals and according to outside requests, manually or automatically connect, disconnect the circuit to achieve the object of the circuit or electrical switch, control, protection, detection, transformation and regulation of the components or equipment.
In general, low-voltage electrical power distribution can be divided into two major categories of electrical appliances and control is the complete set of basic components of electrical equipment components. In industry, agriculture, transportation, defense, and people in the electricity sector, most of the low voltage power supply, so electrical components will directly affect the quality of low-voltage power supply system reliability. The development of low-voltage electrical appliances, depends on the development of national economy and the needs of modern industrial automation.
Low-voltage electrical industry, market capacity and the development of power industry is closely linked with enhancing the level of domestic electricity, and low-voltage electrical production technology continues to evolve to intelligence, the main features of the network into a new generation of low-voltage electrical will be grade products. The first generation of products will be withdrawn from the market in 2010, the second generation of products will be low-end products, low voltage electrical appliances into the third generation and fourth generation of major products and full realization of low-voltage electric network, intelligent, with a variety of field bus connection, but also can be directly connected with the Industrial Ethernet. Some difficulties in installing communication cables occasion or network expansion needs, can use wireless communication technology.
Intelligent low-voltage electrical products in the development. In modern power plants and industrial and mining enterprises, have been widely used in computer monitoring system, and matched with low-voltage circuit breaker made high-performance, intelligent, and requires products with protection, monitoring, testing, self-diagnosis display function.
Low-voltage electrical products to network development, and in everyday life, to develop and improve the distribution and control system intelligent network supporting products. Improve the specifications of various types of ancillary products, variety, in series, standardized and complete Intelligent Network System Master development. Information from: www.tede.cn
