3.2.4 故障檢修維護
係統在發生故障後應進行被動性維護,主要包括以下工作:
(1)在日常工作中應認真按照25項反措要求,充分做好包括DPU網絡通訊崩潰在內的各種事故預想,將運行緊急處理措施、措施、技術措施、檢修步驟編寫成冊,確保機組的運行。
(2)處理DCS故障按照制造廠應用手冊中的要求開展工作,更換前確認卡件模塊型號、地址(應確保與其他設備地址不衝突)、跳線等與被更換卡件一致並嚴格執行在線更換程序。
(3)故障被動維護同樣應嚴格執行工作票制度,避免搶修冒進,應結合具體故障表現進行詳細分析。根據DCS係統自診斷報警、故障現象判斷,找到故障點,通過報警的來驗證維修結果。如:通信接頭接觸不良會引起通信故障,確認通信接頭接觸不良後,利用工具重做接頭;通信線破損應及時更換。 某個卡件故障燈閃爍或者卡件上全部數據都為零,可能的原因是組態信息有錯、卡件處於備用狀態而冗餘端子連接線未接、卡件本身故障、該槽位沒有組態信息等。 當某一生產狀態異常或報警時,可以先找到反映此狀態的儀表,然後順著信號向上傳遞的方向,用儀器逐一檢查信號的正誤,直到查出故障所在。
