Sichuan Electric Power: Tiandun builds a lightning protection system for substations


In recent years, research on smart grids in China has been launched. As an important part of the grid, research and pilot work in the field of digital substations will also lay the foundation for the development of smart grids. The digital substation converts all information acquisition, transmission, processing and output processes of the substation from past analog information to digital information, and establishes a suitable communication network and system. The structure of the digital substation automation system can be physically divided into two categories, namely, intelligent primary equipment and networked secondary equipment; the logical structure can be divided into three levels, according to the IEC communication protocol draft definition, these three The levels are called “process layer”, “spacer layer” and “station control layer”. The new digital substation consists of a signal acquisition system for all digital and optical fibers, digital relay protection and integrated automation systems, digital video and environmental monitoring systems.

      Sichuan Electric Power Company needs to know the on-site environmental conditions of the 500kV substation in real time. The monitoring system must operate normally under severe weather such as thunderstorms. Tiandun lightning protection device becomes the lightning protection supplier of Sichuan Province and is the front-end network of a certain city in Sichuan Province. The camera provides power and network line protection. With the wide application of network cameras, Tiandun M10-220/D05J4 power network is one of the darlings of monitoring systems. In recent years, it has been widely used in high-definition network camera protection such as electric power and intelligent transportation.
