二滩输变电工程共有12条计2000公里500kV 线路,7个500kV 变电站,是国内迄今最大的500kV 线路保护工程,出于系统稳定的需要,保护动作加开关跳闸时间不得超过80ms。该工程总共计有80多面屏柜,须在签定合同后半年内交货。这么大难度的工程,正好充分发挥 LFP-901A 和LFP-902A 所独有的3-10ms 超高速动作且安全可靠的优势;该工程规模大,工期紧,使电自院
The Ertan Power Transmission Project has a total of 12 500kmV lines of 2000km and 7 500kV substations. It is the largest 500kV line protection project in China so far. For the needs of system stability, the protection action and switching trip time must not exceed 80ms. The project has a total of more than 80 screen cabinets and must be delivered within six months after signing the contract. With such a difficult project, the advantages of LFP-901A and LFP-902A’s unique 3-10ms ultra-high-speed operation and safety and reliability are fully exploited. The project is large-scale and the construction period is tight, making the electricity from the hospital
