摘要
特长隧道施工中,掘进到一定长度后,原低压进洞供电方式已不能满足施工用电要求,通过对比分析,采取高压进洞的方式、二级变压或者低压补偿的方式才能满足施工用电不足的问题。结合盆因拉隧道洞内供电实践,介绍低压进洞补偿的技术,对类似高原特长隧道洞内供电有借鉴意义。
When the super-long tunnel is constructed to a certain length,the original low-voltage power supply can no longer meet the corresponding demand,it can be solved through high-voltage cave transmission,secondary voltage transformation and low-voltage compensation.Low-voltage cave compensation technology is hereby introduced based on the power supply practice of Penyingla Tunnel,with a view to provide references to the cave power supply of similar plateau super-long tunnels.
