摘 要:引水隧洞的特点一般是断面小、洞线长、工序多、干扰大、施工条件差、工期较长、单价低、单向掘进时长度大。隧洞内用电设备因供电线路距离增加,电压损失也加大,造成用电设备无法正常使用,甚至无法启动,影响施工生产正常进行。结合小浪底引黄工程垣曲支线隧洞施工中大功率自动补偿式稳压器的使用,介绍一种非"高压进洞"方式解决线路电压损失的方法。The hydraulic tunnel usually has following features:small section,long tunnel line,many working procedures,large interaction,poor construction condition,long construction period,lower unit cost,long distance in oneway excavation. In pace with increase of the power supply distance in tunnel,the voltage loss of the electric equipments will increase. It makes electric equipments can't be used normally,even can't be started,and will preclude the normal operation of tunnel construction. In combination with the application of the high power automatic compensation type voltage regulator in the process to build the tunnel of Yuanqu branch line of the Xiaolangdi Yellow River Diversion Project,the paper introduces a pattern,in which the high-voltage line does not come into the tunnel,to solve the problem of line's voltage loss.
