摘　　要：根据GIL管廊主通风任务与节能目标,采用冬季GIL管廊主通风腔内温度的简化计算方法,获得不同流量下管廊内空气温度分布。在此基础上,对GIL管廊主通风系统节能运行进行优化,确立冬季南北岸各运行两台主通风机低能耗连续运行方案。在GIL管廊冬季持续排风条件下,提出利用空气-空气换热器提取GIL管廊排风余热供暖的技术方案。理论分析,采用该方案后能够极大降低能源的耗费,从而达到节能效果。According to the task of main ventilation of GIL pipe gallery and the goal of energy-saving, the air temperature distribution in the main ventilation cavity of GIL pipe gallery under different flow rates was obtained by adopting the simplified calculation method of temperature in winter. On this basis, the energy-saving operation of the main ventilation system of GIL pipe gallery was optimized, and the low-energy continuous operation scheme of two main ventilators running on the north and south banks in winter was established. Under the condition of continuous exhaust air of GIL pipe gallery in winter, the technical scheme of using air-air heat exchanger to extract exhaust heat of GIL pipe gallery for heating is put forward. Through theoretical analysis, the scheme can greatly reduce the energy consumption and achieve the effect of energy saving.
