摘要
建筑施工现场使用的机械设备中,绝大部分都是以电作为能源的,随着机械化施工水平的提高,使用电动设备也越来越多,长大隧道施工必须解决隧道内大功率用电设备因低压(380 V)输送线路过长而导致其无法正常启动的情况。文章依据工程施工具体情况,针对长大隧道施工提出了将380 V电升压至10 kV的实施措施。
The vast majority of mechanical equipment in construction site is powered by electricity,and the number of them are in-creased with the mechanized level of construction.It’s necessary to solve the situation of falling to normal start of power consumption e-quipment in long tunnel due to the extra-long low-voltage conveyer line.based on the particular case of the construction of long tunnel, implementation measure to improve 380 V electricity into 10 kV is put forward in this paper.
