摘要
经过对丹江口水电厂110、220 kV开关站接地网存在的问题进行分析,并结合前期的全面勘测和局部开挖检查,根据丹江口电厂开关站接地网实际状况,综合考虑南水北调中线丹江口大坝加高施工的影响因素,有针对性地制定了改造方案,有效地解决了目前开关站地网热稳定、电压分布、腐蚀等亟待解决的问题。
The existing problems of 110 and 220kV switch station grounding network in Danjiangkou hydropower plant are analyzed. By taking into account the previously comprehensive survey and local excavation inspection, the grounding network actual status in switch station and the influential factors in South-North Water Diversion Project, the improvement approaches for above-mentioned existing problems are formulated, which effectively solve the problems in switch station such as network hot stability, and voltage distribution , and corrosion.
