| Abstract: | A 12-pulso fixed DC de-icing equipment was developed and tested in Chengqianling substation on November 8th, 2008. When the test current was set at 1200A, the temperature of LGJ-400 lead rose from 8℃ to43℃ and temperature of 2 × LGJ-300 lead from 8℃ to 16℃ after 45 minutes. The equipment has many advantages, such as DC voltage continuous regulation, less harmony content, and so on. It is an effective tool for 0 -40km line de-icing. |
