Low-voltage electrical appliances are widely used in many sectors of the national economy, and the state of fixed asset investment in the whole society is closely related to the early 21st century is a period of rapid development of low-voltage electrical industry in China, and in recent years the low-voltage electrical industry has maintained a growth rate of 10% -15%. The market capacity of low-voltage electrical appliances is closely related to the development of electric power, new energy, industry, real estate, telecommunications and other industries, as well as the adjustment of the demand structure of low-voltage electrical appliances and the potential demand of the international market, which provides a broad space for the future development of the low-voltage electrical appliances industry.


The current moulded case circuit breaker will develop in the direction of high current and small volume.

At present, the molded case circuit breaker to carry out is to high current research direction of continuous development, energy storage type electric operation and hand operation mechanism can be interchangeable, can significantly and effectively reduce the enterprise with electric operation mechanism as well as the thickness of the product reduce the thickness of the distribution cabinet, improve the system short circuit breaking index, and double breakpoint products high breaking index system basic information matching, improve the short withstand index and selective decoupling reliability.


The current market has seen the emergence of small, cost-effective moulded case circuit breakers, which not only save manufacturing costs, but also reduce the thickness of the product and expand the range of applications. In addition, the reduction in the number of parts and the simplification of shapes has made semi-automatic mass production possible.


With the continuous improvement of production technology, there are already 0.1A-25A products and more than 1000A products on the market. The technical specifications are becoming more and more advanced and the performance has been improved, especially in terms of vibration resistance. In the development process, the product structure is becoming more and more modular, compact and integrated, the structure is becoming more and more compact, the combination is flexible, the assembly is more convenient and the appearance is more humane. In addition, the product can be fitted with soft starters, intelligent detectors, etc.


The current research on smart grids at home and abroad focuses on the "intelligence" and "communication" of low-voltage electrical appliances, which will eventually develop into a smart grid and form a low-voltage customer industry for smart grids. The goal of smart grid is to achieve reliable, safe, economic, efficient, environmentally friendly and safe operation of the grid. The low-voltage client of smart grid also has the characteristics of reliability, safety, economy and efficiency, and the construction of smart grid is inseparable from the grid based on low-voltage distribution system and intelligent communication of low-voltage electrical components. The intelligence and communication of these devices have become the development trend of the low-voltage electrical industry.


In view of the accelerated economic expansion of China's internationally renowned enterprise companies in China, and the adjustment of the strategy for China, a new round of assets for restructuring and resource management integration, etc., will have an unpredictable impact on the current industrial organisation of China's low-voltage electrical industry in the process of continuous adjustment and future market development. With the rise of artificial smart grid, the high-grade, mid-grade and low-grade low-voltage electrical appliances safely produced by Taisi Electric will approach the direction of smart grid, which will gradually form a kind of low-voltage end industry of smart grid and become a new growth point of low-voltage electrical industry.
