低壓開關柜的防護等級的選擇

發布單位:四川電器    發布日期: 2017-06-03



低壓開關柜的防護等級是任何一個開關柜有的一個重要的技術參數,防護等級一般用IPxx來標示,那么我們在設計開關柜時,如何來設定開關柜的防護等級呢?今天四川高低壓電氣成套廠家四川電器就來給大家介紹一下。
低壓開關柜的IP防護型式有兩種用途:其一是防止工作人員因為疏忽而觸及帶電部分,其二是防止柜內安裝的電氣設備遭受塵埃和水的侵害。防護型式IP等級的意義我們之前也介紹過。
對于一般的低壓開關柜來說,默認的IP防護等級為IP30或IP40。
但從低壓開關柜的使用來看,變電站的工作人員都希望低壓開關柜能有較高的IP防護等級,但高IP防護等級卻直接影響了低壓開關柜的散熱效率,因此造成低壓開關柜全面降容。若將不合理的高IP防護等級的開關柜直接安裝投運,必將因為發熱嚴重而造成系統停止運作或發生故障。
所以低壓開關柜的設計者和使用者在確定低壓開關柜的方案和結構是務必要注意。
