开闭所被广泛应用于中压配电网层面,主要起到电力的分配、转供和互联等作用.相较于户外环网柜,开闭所的运行环境有所改善,但由于各方面的原因,开闭所故障还是时有发生,这给供电可靠性的提升带来不小的压力.本文基于笔者的运行经验,从柜型选择、防潮补强、试验维护等方面就如何加强开闭所运行稳定性进行研究. 实践检验表明,本文的研究成果对延长开闭所内开关柜寿命、提升中压层面的供电可靠性等有十分显著的作用,值得推广.
開閉所被廣汎應用于中壓配電網層麵,主要起到電力的分配、轉供和互聯等作用.相較于戶外環網櫃,開閉所的運行環境有所改善,但由于各方麵的原因,開閉所故障還是時有髮生,這給供電可靠性的提升帶來不小的壓力.本文基于筆者的運行經驗,從櫃型選擇、防潮補彊、試驗維護等方麵就如何加彊開閉所運行穩定性進行研究. 實踐檢驗錶明,本文的研究成果對延長開閉所內開關櫃壽命、提升中壓層麵的供電可靠性等有十分顯著的作用,值得推廣.

Switching stations are widely used in medium-voltage distribution network, mainly for distribution, supply and the interconnection of electric power and so on. Compared to the outdoor ring main unit, the operation environment of switching stations is improved. However, because of various reasons, switch failures still occur, which brings about much pressure on the improvement of power supply reliability. Based on the author's experi-ence, the paper researches on how to reinforce the stability of switching stations from perspectives of selecting cab-inet, moisture-proof reinforcement, testing and maintenance. The results show that the research has a significant role in extending the switch life, and enhancing the reliability of medium voltage level, which is worth promoting.
