Abstract
A 12-pulse 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℃ to 43℃ and temperature of 2×LGJ-300 lead from 8℃ to 16℃ after 45 minutes.The equipment has many advantages
