Intelligent Application of Four-State Switching of 6kV Medium Voltage Switch based on DCS System
The realization of program-controlled operation of 6kV switch in DCS system is the technical direction of the development of smart power plant in the future. In the design and selection of auxiliary power system, the 6kV switch of Huaneng Luoyuan power generation company specifically selected the ZS1 circuit breaker of Xiamen abb, equipped with electric handcart, and realized remote swing in / swing out handcart operation in DCS system. Through the upgrading and transformation of 6kV switch cabinet, the earth switch and low-voltage secondary miniature circuit breaker were upgraded and transformed into electric knife and intelligent micro break and the DCS platform was used to integrate video monitoring and control signals to realize the four state switching one button operation of 6kV switch and realize on-site unmanned management.
