發布時間:2013/12/23  瀏覽:4236 - 返回

高壓電流互感器使用條件: 
1、溫度-25~40℃; 
2、海拔高度≤1000m; 
3、地震烈度Ⅷ(8)度; 

4、污穢等級:戶內不低于2級,戶外不低于3級; 

5、戶內需考慮:(1)環境空氣無明顯灰塵、煙、腐蝕性氣體、蒸汽或鹽等污穢;(2)濕度條件:24h內測得的相對濕度平均值不超過95%;24h內水蒸氣壓力平均不超過2.2kPa;一個月內相對濕度平均值不超過90%;一個月內水蒸氣壓力平均不超過1.8kPa。 

6、戶外需考慮:(1)24h期間測得的環境氣溫平均值不超過40℃;(2)日照輻射達到1000W/m2(晴天中午)時應予以考慮;(3)環境空氣可能有灰塵、煙、腐蝕性氣體、蒸汽或鹽污穢;(4)風壓不超過700Pa(相當于34m/s);(5)應考慮出現凝露和降水。 

7、高壓電流互感器特殊使用條件(另作考慮)
