試驗100次。啟動成功率應(yīng)大于99%。

Test 100 times. The success rate of startup should be greater than 99%.

否則，則認為此項不合格。

Otherwise, it will be considered as unqualified.

檢查機組平均故障間隔期

Check the average interval between failures of the unit

檢查方法：機組帶cosФ=0.8的額定負載，連續(xù)或累計運行1000h以上，焦化機發(fā)電機均不應(yīng)出現(xiàn)故障，控制電路的 元件不應(yīng)出現(xiàn)二次以上故障

Inspection method: Unit with cos Ф= With a rated load of 0.8 and continuous or cumulative operation for more than 1000 hours, the coking machine generator should not have any faults, and the components of the control circuit should not have more than two faults

否則，則認為此項不合格。此項指標允許在實際運行中進行考核。

Otherwise, it will be considered as unqualified. This indicator allows for assessment in actual operation.

檢查機組帶可控硅負載的運行情況

Check the operation of the unit with thyristor load

試驗方法：機組帶cosФ≥0.5的三相可控硅整流器負載，在機組額定容量的10%～50%范圍內(nèi)任一點上均應(yīng)能穩(wěn)定工作 。

Test method: Unit with cos Ф≥ A three-phase thyristor rectifier with a load of 0.5 should be able to operate stably at any point within the range of 10% to 50% of the rated capacity of the unit.

如果產(chǎn)生低頻振蕩，應(yīng)實行調(diào)整，使之能穩(wěn)定工作，否則認為此項不合格。

If low-frequency oscillation occurs, adjustments should be made to ensure stable operation, otherwise it is considered unqualified.

檢查自動化機組的聯(lián)動試

Check the linkage test of the automation unit

檢查方法：兩臺機組應(yīng)互為主備用，任選一臺作主用，人為切斷市電，主用機組自動啟動成功后供電。

Inspection method: Two units should be used as primary and backup for each other, with either unit being selected as primary. The mains power should be manually cut off, and the primary unit should automatically start and supply power.

制造一個故障 ，使主用機組自動停機備用機組則應(yīng)自動成功后供電。

Create a fault that causes the main unit to automatically shut down, and the backup unit should automatically supply power after successful operation.

使市電恢復(fù)后，備用機組應(yīng)級自動停機。

After restoring the mains power, the standby unit should automatically shut down.

如不合格，找出原因，排 除故障。

If it is not qualified, identify the cause and troubleshoot.

兩臺機組分別為主用，復(fù)試三次，如仍有一次不合格，則認為此項不合格。

Two units are used as the main unit and undergo three retests. If there is still one failure, it is considered as unqualified.

檢查自動化焦化發(fā)電機組自動啟動功能

Check the automatic start function of the automated coking generator set

試驗方法：接通啟動電源，將機組工作方式選擇開關(guān)搬向自動，送入啟動指令，并且人為使機組啟動不成功，機組應(yīng) 自動啟動三次。

Test method: Connect the starting power, move the switch for selecting the working mode of the unit to automatic, send a starting command, and if the unit fails to start due to human intervention, the unit should start automatically three times.

試驗三次，只要有一次不合格，復(fù)試次數(shù)加倍，若仍有一次不合格，則認為此項不合格。

Test three times, and if there is one failure, the number of retests will be doubled. If there is still one failure, it will be considered as unqualified.

檢查自動化機組的自動補給裝置

Check the automatic supply device of the automation unit

試驗方法：在控制電路電路完全聯(lián)結(jié)完畢后，將工作方式選擇開關(guān)搬向自動人為放水放油至低液位，應(yīng)能自動補給， 當液面上升到高液位時補給應(yīng)能自動停止。

Test method: After the control circuit is fully connected, move the working mode selection switch to the automatic manual water and oil discharge to the low liquid level, which should be able to automatically supply. When the liquid level rises to the high liquid level, the supply should be able to automatically stop.

試驗三次，只要有一次不合格，復(fù)試次數(shù)加倍，若仍有一次不合格，則認為此項不合格。

Test three times, and if there is one failure, the number of retests will be doubled. If there is still one failure, it will be considered as unqualified.
