Technology of industrial switch power system
Industrial switch professional in order to achieve the flexible and varied requirements of industrial production and application design, show a cost-effective power line communication solution. Industrial switch provides high availability support for realizing intelligent power system and integration of information flow, service flow and power flow.
Power systems for industrial switches:
Online monitoring of power system is an indispensable part of smart grid in the future. Smart grid means not only intelligent control, but also intelligent processing and management of power grid operation information. Intelligent control can be realized only when information intelligent management is achieved.
In the process of building smart grid, the online monitoring technology of power equipment develops rapidly, and the vast majority of substation equipment, generators, cables, lines, etc., have online monitoring projects.
Industrial switch, as an important distribution network communication solution, is briefly analyzed in terms of protocol and networking.
The protocols of industrial switches have been standardized for a long time, including the underlying protocols, network redundancy protocols, management protocols, and network precise clock transmission protocols. Products from different manufacturers have good interoperability and can realize hybrid networking. The working range of -40℃ ~ 85 ℃ can fully meet the industrial needs and meet the construction of the distribution network system.
Industrial Ethernet switches mainly use piecewise redundancy, intersecting ring, and tangential ring to improve network reliability. Multiple optical ports are flexibly configured and highly integrated, making the elastic design more convenient for power grid construction
The power grid realizes digital signal network communication. Voltage and current signals collected by electronic transformers in each region are converted into digital signals and transmitted to switches through optical fibers. Secondary devices acquire data through switches and process them. Industrial switch plays a huge role in data collection, production management, operation and maintenance, security monitoring, metering and user interaction. Industrial Ethernet technology, optical fiber technology, information processing technology and other development and penetration into various fields, power system monitoring technology is widely used in these advanced scientific research results, so that online measurement technology gradually toward the practical stage.
