變電站設(shè)備缺陷分類

1、變電站設(shè)備缺陷通常分為以下三類：一類缺陷Ⅰ：指設(shè)備處于嚴(yán)重異常狀態(tài)，必須立即處理，否則將影響設(shè)備及系統(tǒng)運(yùn)行的安全。二類缺陷Ⅱ：指設(shè)備有明顯異常狀態(tài)需盡快處理。三類缺陷 Ⅲ：指設(shè)備有異?；蛲庥^缺陷，不影響正常運(yùn)行，可以在設(shè)備定期檢修時(shí)進(jìn)行處理。或其它非一二類缺陷。輸變電設(shè)備缺陷分類目錄一、變電設(shè)備 .......................................................................
