摘要
研制了1套基于12脉波的固定式直流融冰装置，于2008年11月8日在郴州城前岭变电站完成现场试验，试验电流1200A，45min后，LGJ-400导线温度由8℃上升至43℃，2×LGJ300导线温度由8℃上升至16℃。装置具有直流输出电压连续可调、谐波含量小等优点，为0～40km线路融冰提供了一种有效的技术手段。
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.
