可立即對(duì)UPS 電源各開關(guān)狀態(tài)及電量各參數(shù)進(jìn)行檢查， 電源柜三相電源電壓無異常，主路、旁路開關(guān)均處于合閘位置，電流為 0；將 UPS 輸出屏主進(jìn)開關(guān)分閘；
按 UPS 本體故障清除鍵按鈕；
將UPS 輸入主、旁路斷路器分閘，靜待 30 秒后恢復(fù)合閘；此時(shí) UPS 自動(dòng)轉(zhuǎn)為旁路運(yùn)行狀態(tài)；
將 UPS 運(yùn)行狀態(tài)由旁路供電模式轉(zhuǎn)換為正常整流逆變模式；檢查 UPS 輸出各項(xiàng)電量參數(shù)無異常；此時(shí)再將電池組開關(guān)由跳位分閘到分位，然后重新進(jìn)行合閘，開關(guān)恢復(fù)正常合閘位置；
將 UPS 輸出屏各開關(guān)恢復(fù)合閘位置，機(jī)房失電列頭柜恢復(fù)供電；
通知 UPS 廠家人員到場(chǎng)對(duì)故障設(shè)備進(jìn)行檢查，排除故障隱患。
The switch status and power parameters of UPS power supply can be checked immediately. There is no abnormality in the three-phase power supply voltage of the power cabinet. The main circuit and bypass switches are in the closing position, and the current is 0; Open the main incoming switch of UPS output panel;
Press the ups body fault clearing button;
Open the ups input main and bypass circuit breakers, wait for 30 seconds and then resume closing; At this time, ups will automatically switch to bypass operation state;
Convert the operation state of ups from bypass power supply mode to normal rectifier inverter mode; Check that all power parameters output by ups are normal; At this time, open the battery pack switch from the tripping position to the opening position, and then close it again, and the switch returns to the normal closing position;
Restore the switches of UPS output panel to the closing position, and restore the power supply to the column head cabinet after power loss in the machine room;
Inform the ups manufacturer's personnel to check the faulty equipment and eliminate the hidden trouble.
