使用新的或者是經(jīng)過(guò)大修的發(fā)電機(jī)組需要知道的4點(diǎn):
Four points to know when using new or overhauled generator sets:
1、對(duì)于新的或者是長(zhǎng)期沒(méi)有使用的發(fā)電機(jī)組在進(jìn)入正常運(yùn)行之前,一定要經(jīng)過(guò)檢查,尤其是要檢查繞接線的情況、組絕緣的情況,如果有異樣,必須立刻進(jìn)行處理。
1. Before entering normal operation, new or long-unused generator sets must be inspected, especially the condition of winding and insulation. If there is any abnormality, it must be handled immediately.
2、發(fā)電機(jī)組發(fā)動(dòng)后要慢慢的提高轉(zhuǎn)速,要在經(jīng)過(guò)檢查確認(rèn)所有情況都完好的前提下才可以進(jìn)行低速到額定轉(zhuǎn)速的空載運(yùn)行,空載運(yùn)行的時(shí)候,重點(diǎn)檢查機(jī)油壓力,是否有異響,勵(lì)磁電流、三相電壓變化等,如果有異常情況必須立即停機(jī)進(jìn)行檢查,了解情況后再發(fā)動(dòng),如果,機(jī)組正常的話就可以直接進(jìn)入到正常運(yùn)行中,工作人員要嚴(yán)密監(jiān)視控制屏上的儀表的變化情況,是否在許可范圍并作相應(yīng)的調(diào)整。
2. After the generator set is started, the speed should be slowly increased. The no-load operation from low speed to rated speed can be carried out only after all conditions are checked and confirmed to be in good condition. During the no-load operation, the oil pressure, whether there is abnormal noise, excitation current, three-phase voltage change, etc. should be checked. If there is any abnormal condition, the generator must be stopped immediately for inspection, and the engine can be started after understanding the situation. If, If the unit is normal, it can directly enter the normal operation. The staff should closely monitor the change of the instrument on the control panel to see if it is within the permitted range and make corresponding adjustments.
3、操作時(shí),工作人員要和帶電設(shè)備保持一個(gè)安全的距離并且穿戴好勞動(dòng)防護(hù)裝備,倒閘操作時(shí)要注意先后順序,停電的時(shí)候先斷開各個(gè)支脈的開關(guān)然后再斷開總開關(guān)之后再進(jìn)行四極雙投刀閘切換位置,送電的時(shí)候,順序相反進(jìn)行,正常停機(jī)要先卸掉部分負(fù)載再斷總開關(guān),后關(guān)柴油機(jī),不可以不拉斷總開關(guān),隨著發(fā)電機(jī)組熄火而自行停電,停機(jī)后對(duì)機(jī)組作常規(guī)性檢查,并記錄運(yùn)行情況
3. During operation, the staff should keep a safe distance from the live equipment and wear labor protection equipment. During switching operation, attention should be paid to the sequence. In case of power failure, first disconnect the switches of each branch, then disconnect the main switch, and then carry out the four-pole double-switch switch switching. During power transmission, the sequence is reversed. During normal shutdown, first remove part of the load, then disconnect the main switch, and finally turn off the diesel engine, It is not allowed to cut off the main switch and cut off the power automatically with the generator unit flameout. After shutdown, conduct routine inspection on the unit and record the operation condition
4、要是發(fā)生工作人員觸電的情況,必須立刻切斷電源開關(guān)或者是用絕緣器具快速使電源斷掉或脫離電源,然后再進(jìn)行搶救并請(qǐng)醫(yī)生來(lái)現(xiàn)場(chǎng)搶救,萬(wàn)一遇有電氣設(shè)備遇到水災(zāi)時(shí),必須馬上去把所有電源切斷并告知當(dāng)?shù)毓╇娝缓筮M(jìn)行救火,對(duì)帶電設(shè)備救火要.
4. In case of electric shock of the staff, the power switch must be cut off immediately or the power supply must be quickly cut off or separated from the power supply with insulating apparatus, and then the rescue must be carried out and the doctor should be sent to the scene for rescue. In case of a flood of electrical equipment, all electrical sources must be cut off immediately and the local power supply station must be informed, and then the fire fighting must be carried out for the live equipment
