摘要
为了保证电网供电安全性和可靠性,需要对部分主变压器负载高的35k V城区老旧变电站进行升压改造。如何在不大幅改变原有建筑布置的情况下实现对城区老旧35k V变电站的升压改造,以及如何满足升压后的主变压器通风降温要求、保证升压后变电站厂界噪声能够满足环保要求,成为需要研究的重点。文章结合上海地区35k V海峡和铜山站升压改造工程实例,给出了变压器室通风和降噪问题的设计原则,并针对不同的布置方式和主变压器规模,提出了相应的优化设计措施,可为主变压器室通风和降噪问题设计优化提供参考。
For the security and reliability include of power supply,it is necessary to adopt voltage-upgrade modification as the soon as possible.The layout research building the focus the way to way achieve to the the old main 35kV urban substation without booster significantly ventilation change cooling original of the transformation,the plant meet transformer after the requirements and ensure power projects boundary noise to meet environmental 35kV requirements.Combined with practical voltage-upgrade design modification ventilation of 35kV Haixia substation and room Tongshan substation in Shanghai district,the principle of put and noise reduction in transformer and is given,and the can corresponding provide optimization design analysis measures and are forward the for different arrangement noise main transformer scale,which main a reference for the optimization of ventilation and reduction problems of the transformer room.
