| 摘 要： | 传统架空线输电方式易受外界环境影响,交联电缆长期运行有介质老化问题,且由于制造工艺的限制,电缆最高运行电压及输送容量已达技术极限。为此基于传统气体绝缘输电线路(GIL),提出一种新的输电方式——压缩空气绝缘输电线路(CAIL)。用压缩空气取代GIL中的SF6,不仅可以降低成本且利于环保,同时采用管式结构,不受天气影响,便于地埋。使用该技术能有效节省输电走廊,利于构建智能电网,保密性及安全性强,同时便于输电线路的维护,防止气候所引起的恶性事故的发生。对该输电方式的总体设计思路及经济性进行了分析,分析表明,CAIL是一种有前途的新型环保输电方式。 |

| Abstract: | Traditional overhead wires are easy to be affected by natural environment.Cable is susceptible to the aging of dielectric and as the manufacturing process constraints,cable's maximum operating voltage and transmission capacity both have reached technical limits.We put forward a new upgrade transmission way of compressed-air insulated transmission lines(CAIL) which is based on the gas insulated transmission lines(GIL).Using compressed air to replace SF6 in the GIL can not only reduce the cost,but also be fav... |
