摘要
近几年来电网大面积覆冰事故发生的频率明显增加,2000年来发生的事故次数甚至高于50年代至90年代所有次数的总和。国内外通行的机械除冰方法有"adhoc"法、滑轮辗压铲刮法、强力振动法、电脉冲除冰、高频高压激励融冰法和新型机器人除冰,这些方法各有优缺点,根据贵阳地区输电线路除冰需求,设计带电机械震动除冰装置。全套设备重量约20kg,通过专用背包即可背负,3~5名熟练工人在15分钟内就可以完成一次除冰工作。
According to deicing need for transmission lines in Guiyang,a charged mechanical vibration defroster is designed.The whole set of equipment weighs about 20 kg,which can be easily carried by special backpacks.Utilizing the equipment,a deicing task could be accomplished by 3-5 skilled workers within 15 min.The method introduced by the author is highly feasible,efficient and secure,the transmission line deicing job could be completed on ground.
