| 摘 要： | 输电线路覆冰后,可能造成导线断线、杆塔倾覆等设备损坏,在覆冰脱落过程中,可能引起线路舞动,多次短路跳闸,严重威胁变电站安全运行,影响对用户的安全可靠供电.东北地区日气温变化大,导线覆冰后因气温骤降,覆冰时间长,清除极为困难.本文结合目前运行的66 kV变电站无融冰设施,受现场限制建设专用融冰设施困难的实际,介绍了移动式...

| Abstract: | The ice coating of overhead transmission line might lead to such trouble of equipment as wire breakage and tower collapse etc.Falling off of ice coating may cause wire sloshing and multiple short-circuit trips,which endanger seriously the safe operation of substations and influence the safe and reliable power supply to the user.Removal of ice from wire is extremely difficult due to big daily temperature difference,sudden drop of temperature after ice-coating and long ice-coating time of wire.In this paper,based on no ice-melting facilities at presently operated 66 kV substation and actual situation of limitation of setting up special ice-melting facilities at site,the research and site test of portable AC ice-melting device are introduced. |
