Avoidance of substation DC system grounding construction tactics

【摘要】隨著我國電網(wǎng)的不斷發(fā)展，變電站設(shè)施的不斷普及，如何更好的對變電站進(jìn)行技術(shù)工藝方面的完善顯得十分重要。目前，我國在避免變電站直流系統(tǒng)接地方面的工作還不夠到位，許多變電站由于各種人為施工因素或外界環(huán)境因素經(jīng)常會出現(xiàn)直流系統(tǒng)接地的現(xiàn)象。變電站直流系統(tǒng)接地將會對變電站的設(shè)備造成損害，同時對變電站各設(shè)備的安全運(yùn)行產(chǎn)生極大威脅。因此，我們在變電站具體施工的過程中，要對直流系統(tǒng)接地的原因進(jìn)行細(xì)致的分析和研究，然后在施工過程中采用有效的施工策略對變電站直流系統(tǒng)接地的情況進(jìn)行預(yù)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.
