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

45 min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

0 km线路融冰提供了一种有效的技术手段。

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

such as DC voltage continuous regulation

less harmony content

and so on.It is an effective tool for 0

0km line de-icing.
