避免变电站直流系统接地的施工策略（原创）.doc

Avoidance of substation DC system grounding construction tactics

【摘要】随着我国电网的不断发展，变电站设施的不断普及，如何更好的对变电站进行技术工艺方面的完善显得十分重要。目前，我国在避免变电站直流系统接地方面的工作还不够到位，许多变电站由于各种人为施工因素或外界环境因素经常会出现直流系统接地的现象。变电站直流系统接地将会对变电站的设备造成损害，同时对变电站各设备的安全运行产生极大威胁。因此，我们在变电站具体施工的过程中，要对直流系统接地的原因进行细致的分析和研究，然后在施工过程中采用有效的施工策略对变电站直流系统接地的情况进行预防。

[ Abstract ] along with the our country electric network unceasing development, the increasing popularity of substation facilities, how better to substation the technical aspects of the improvement is very important. At present, our country is in avoid of substation DC system grounding work is not in place, a lot of substation due to various human construction factors or environmental factors often appear the phenomenon of DC system grounding. Substation DC system grounding of substation equipment will cause damage, at the same time the substation on the safe operation of equipment to produce a great threat to. Therefore, we in the substation specific construction process, the DC system grounding of the reasons for a detailed analysis and research, and then in the process of construction the construction strategy of substation DC system grounding of prevention.
