摘要
采用电力隧道敷设大截面高压电缆输送电力是城市发展的趋势,电力隧道是电网的重要设施,隧道内的通风设计具有其特殊性。本文介绍了电力电缆隧道工程通风系统的技术方案,包括机械通风方案、通风口设计、通风量的确定、通风工作井的布置等。以广州某地下电缆隧道工程的通风设计为实例,进一步探讨电缆隧道隧道通风设计的最佳方案。
Applied large section ttmnel to hold high voltage cable to transmit electricity is the trend of urban development, so the electricity tunnel is an important part of the power grid, which ventilation design has its uniqueness. This paper introduced a power cable tunnel ventilation program, including program of mechanical ventilation, vent design, the determination of ventilation rate, the arrangement of ventilation well, etc. Taking an underground cable tunnel as an example, a further discuss for the.best ventilation program was carried.
