1、啟動前要檢查水、油、潤滑油是否符合要求，風扇皮帶是否達到規(guī)定要求。                                                                                                                                                                                                                                                                                                                                                                                  

2、作業(yè)前檢查內(nèi)燃機與發(fā)電機傳動部分，應連接可靠，輸出線路的導線絕緣良好，各儀表齊全、有效。                                                                                                                                                                           

3、開始供電時要注意用電設(shè)備是否有人看護，無人時應派人看護后方可送電。                                                                                                                                                                                                                                                                                                                                                                                  

4、發(fā)電機工作時，操作人員不能離開，有意外事故時，必須立即切斷電源，停止供電。                                                                                                                                                                                                                                                                                  

5、新裝、大修或停用10d以上的發(fā)電機，使用前應測量定子和勵磁回路的絕緣電阻以及吸收比，定子的絕緣電阻不得低于上次所測值的30％，勵磁回路的絕緣電阻不得低于0.5MΩ，吸收比不得小于1.3，并應做好測量記錄。

6、啟動前應先將勵磁變阻器的電阻值放在最大位置上，然后切斷供電輸出主開關(guān)，接合中性點接地開關(guān)。有離合器的機組，應先啟動內(nèi)燃機空載運轉(zhuǎn)，待正常后再接合發(fā)電機。

7、啟動后檢查發(fā)電機在升速中應無異響，滑環(huán)及整流子上電刷接觸良好，無跳動及冒火花現(xiàn)象。待運轉(zhuǎn)穩(wěn)定，頻率、電壓達到額定值后，方可向外供電。載荷應逐步增大，三相應保持平衡。

8、發(fā)電機開始運轉(zhuǎn)后，即應認為全部電氣設(shè)備均已帶電。                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    

9、發(fā)電機連續(xù)運行的最高和最低允許電壓值不得超過額定值的±10％。其正常運行的電壓變動范圍應在額定值的±5％以內(nèi)，功率因數(shù)為額定值時，發(fā)電機額定容量應不變。

10、發(fā)電機在額定頻率值運行時，其變動范圍不得超過±0.5Hz。                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      

11、發(fā)電機功率因數(shù)不得超過遲相（滯后）0.95。有自動勵磁調(diào)節(jié)裝置的，可在功率因數(shù)為l的條件下運行，必要時可允許短時間在遲相0.95～1的范圍內(nèi)運行。

12、發(fā)電機運行中應經(jīng)常檢查并確認各儀表指示及各運轉(zhuǎn)部分正常，并應隨時調(diào)整發(fā)電機的載荷。定子、轉(zhuǎn)子電流不得超過允許值。

13、停機前應先切斷各供電分路主開關(guān)，逐步減少載荷，然后切斷發(fā)電機供電主開關(guān)，將勵磁變阻器復回到電阻最大值位置，使電壓降至最低值，再切斷勵磁開關(guān)和中性點接地開關(guān)，最后停止內(nèi)燃機運轉(zhuǎn)。

三、樹立法制觀念，認真執(zhí)行設(shè)備操作規(guī)程及各項安全規(guī)章制度。                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     

四、 遵守勞動紀律，堅守崗位。不干私活，不遲到，不早退，工作中不吸煙，不吃食物，不說笑打逗，不穿拖鞋。

五、熱愛本職工作，努力學習以“四懂三會”為主要內(nèi)容的技術(shù)知識，不斷提高操作技術(shù)水平。                                                                                                                                                                                   

在操作過程中，不按此規(guī)定者，所發(fā)生一切事故，責任自負。
