摘要
依托某具体工程,通过技术经济比较论述变电站500kV配电装置采用HGIS设备,在一期工程只有4个元件时,两个完整串不装设出线隔离开关的方案是可行的。该方案的提出,大大减少了工程的一期投资,将使500kV HGIS得到更广泛的应用。
Depending on a practical project and based on the technical - economical comparison of HGIS devices applied in the 500KV power distribution equipment of the substation, the paper identifies that the scheme without implementing outgoing insulated switches on two complete strings is feasible when the first stage engineering project only has four components. With this scheme, the first stage financial investment could be sharply decreased, and the 500KV HGIS could be used more widely.
