摘要
针对中心城区变电站用地矛盾的问题,提出了220/20 kV直降变电站与商业楼盘合建的供电模式。结合苏州某配电网建设和管理示范区的高可靠性的负荷需求,给出了220/20 kV变电站与商业楼盘合建的具体工程方案,并从防雷接地设计、对应的通道设计、电缆走向、通风、排水方案、消防、电磁防护、噪声治理、振动隔离方面指出应注意的问题及相应的解决思路,以期保证变电站安全运行,并对周边环境的影响达到最小。
Aiming at the problem of landuse conflicts of substation in the city centre,this paper proposed the power supply mode of 220/20 kV directly step-down substation integrated with commercial estate.Combined with the demand of high reliability load in a Suzhou distribution network construction and management demonstration area,this paper gave the specific engineering proposals of 220/20 kV directly step-down substation integrated with commercial estate.In order to ensure the safe operation of the substation and minimize the influence on the surrounding environment,some problems should be paid attention to and the corresponding solving ideas were pointed out,including design of lightning protection and earthing,channel design,cable direction,aeration,drainage scheme,fire protection,electromagnetic protection,noise control and vibration isolation etc.
