The world’s first 800 KV transformer for the main installation is complete
World wind electric wind generators grid report: Recently, Xiangjiaba – Shanghai ± 800 KV HVDC transmission demonstration project, “Fengxian Converter Station”’s first 800 KV high voltage converter transformer valve side of the smooth installation of casing in place, marking the commutation transformer of the main installation is complete.
It is understood that the units converter converter transformer capacity of 297.1 thousand Kvar (1000 lacking), DC-side casing pressure rating Chao Guo 800 KV, tube length of the DC side of nearly 12 m, the weight of nearly 5 T. In order to successfully complete the installation of converter transformers, All units attached great importance to set up a special installation of scientific and technological research and development group for rheological and shift QC group, the installation process standardization work, the successful completion of the first units of the main converter transformer installation.
