Low-voltage circuit breakers are widely used in low-voltage power distribution systems. They are a kind of protective electrical components with functions of open circuit protection, overload protection, control and isolation. They are suitable for low-voltage power distribution systems for industrial and civil construction terminals. If the low-voltage circuit breaker is improperly designed in the power distribution system, it will affect the normal operation of the power supply circuit. Therefore, when designing a low-voltage power distribution system, attention should be paid to the details of the selectivity and cascade protection of the low-voltage circuit breaker. The situation of “three pillars†of state-owned, private and foreign-funded enterprises in the low-voltage electrical appliance industry has been going on for many years. At present, ABB , Siemens, Schneider Electric and other international electrical companies have entered the Chinese market in full, and actively occupy the domestic middle and low-end market while occupying the high-end product market. With the globalization of the market, the mutual penetration of foreign-funded enterprises and domestic enterprises is another inevitable trend in the development of the low-voltage electrical industry.
The market research report of the low-voltage electrical industry shows that the arrival of the intelligent era has reduced the operating and production costs of enterprises and has changed your life. The application of intelligent technology in the manufacture of low-voltage electrical appliances has enabled low-voltage electrical appliances to develop in the direction of the fourth generation of intelligent and communicable. At present, the standards for intelligent low-voltage electrical appliances have not been accurately defined at home and abroad, but the protection functions are more complete, and the real-time current parameters, fault recording and display, and internal fault self-diagnosis of intelligent low-voltage electrical appliances have entered the mass production stage. International companies such as Schneider, Remyde, and Panasonic have quickly seized the Chinese market and occupied the market share of most intelligent low-voltage electrical appliances. Sino-foreign joint ventures will occupy a larger quota of smart low-voltage electrical appliances market, which is based on certain facts. Based on its own research and development strength and technical support from Samsung, Fuji, Hecun and other companies, Wal-Mart Electric of Germany launched the VORCPS series of low-voltage power distribution appliances in 2016. The series covers air circuit breakers, molded case circuit breakers and dual power supply conversion. Switches, miniature circuit breakers, smart power meters, etc. With the concept of “excellent in shape and wisdom in the coreâ€, Remide is the VORCPS series dual power transfer switch that fills the blank of domestic products, and is the Jiangsu Power Supply Company, Zhejiang Power Supply Company, Fujian Power Supply Company, Guizhou Province. Power supply companies provide high-quality intelligent low-voltage electrical products and application services. In this war without smoke, they quickly seized the domestic intelligent low-voltage electrical equipment and application service market with the VORCPS series of intelligent low-voltage power distribution products. The domestic top 500 enterprises such as China Power Group, SAIC Group and Industrial and Commercial Bank also became theirs. Paying attention to customers, Wal-Mart Electric has completed the preliminary product layout.
