網(wǎng)絡(luò)優(yōu)化資料:
絕緣距離;
對于電壓低于500伏的電路,空氣間隙大于10毫米,排母排針生產(chǎn)爬電距離大于12毫米,5.12.2電壓3。6-40.5kV線路的最小絕緣距離應(yīng)符合表5的要求;
母線的選擇;
樣品要求,根據(jù)圖紙要求,
如果圖紙沒有要求,中壓柜按表6選擇。低壓柜可根據(jù)銅母線安全電流表選擇。
母線的標(biāo)識:
母線應(yīng)標(biāo)有不同顏色的熱縮套管。如果排母排針怎么連接熱縮套管的顏色不能滿足要求,可以使用母線專用相序色標(biāo),并粘貼在明顯的地方。
母線的顏色標(biāo)識;
三相交流電路;a相為黃色,b相為綠色,c相為紅色,n線為淺藍色,PE線為黃綠色。
DC電路;正極極棕,負(fù)極藍色,接地中性線淡藍色,母線搭接5.15;
