17、，它可以用所占的電角度和所占的槽數(shù)來表示。（V ）8、電動機定子槽數(shù)與轉(zhuǎn)子槽數(shù)一定相等的。（ X ）9、汽輪發(fā)電機只能滯相運行。（ X ）10、 在進行三相交流電機繞組連接時，只要保證每相繞圈數(shù)相等，就能夠保證產(chǎn)生三相平衡的電動勢。（ X ）11、高壓設(shè)備全部停電的工作系指室內(nèi)高壓設(shè)備全部停電（包括架空線路與電纜引入線在內(nèi)），以及室外高壓設(shè)備全部停電（包括架空線路與電纜引入線在內(nèi)）。 （ X ）12、 同步發(fā)電機的自同步是指不檢查同期條件是否滿足的情況下，且勵磁繞組開路的狀態(tài)下，將發(fā)電機并列。（ X ）13、同步發(fā)電機調(diào)相運行時，可向系統(tǒng)送出少量有功功率以及無功功率。（ X ）14、一臺定子繞

18、組星形連接的三相異步電動機，若在空載運行時A 相繞組斷線，則電動機必將停止轉(zhuǎn)動。（ X ）15、 水冷汽輪發(fā)電機的轉(zhuǎn)子水系統(tǒng)的供水總壓力等于將水甩出的離心壓力與轉(zhuǎn)子進水處施加壓力之和。（V ）16、系統(tǒng)有功過剩時，會導(dǎo)致頻率和電壓的升高。（V ）17 、深槽型的鼠籠式交流異步電動機的起動性能與運行性能均比普通籠型的異步電動機好。（ X ）18、盡量采用先進的工藝和新技術(shù)、新辦法，積極推廣新材料、新工具，提高工作效率，縮短檢修工期是檢修機構(gòu)的基本職責(zé)之一。（V ）19、在系統(tǒng)故障的緊急情況下，允許同步發(fā)電機采用非同期并列方法。（ X ）20、 并勵直流發(fā)電機只要主磁路有剩磁，電樞繞組與勵磁繞組連

32、為 10000MW的電力網(wǎng)，頻率偏差超出 50 ± 0.2Hz,延續(xù)時間為 50min, 則應(yīng)定為一類障礙。（V ）32、在不知頂升重物重量的情況下，為省力可以加長千斤頂壓把。（ X ）33、鏈條葫蘆應(yīng)定期加潤滑油，但嚴(yán)防油滲進摩擦片內(nèi)部而失去自鎖作用。（V ）34、200MW汽輪發(fā)電機組標(biāo)準(zhǔn)項目檢修，小修停用時間為14天。（V ）35、在很多場合下，可在電刷的滑出邊上看到一些火花，特征為呈點狀火花、白色或藍中帶白的顏色。這種火花很危險，會很快破壞整流子的正常運行，并燒壞整流子。（ X ）36、在多數(shù)電刷下發(fā)生直徑在1mm 的球狀火花或滴狀黃色火花時，電刷的接觸面上沿轉(zhuǎn)動方向覆蓋有無

33、光澤的黑帶，這種火花對整流子不會損壞。（ X ）37、經(jīng)檢查發(fā)現(xiàn)由于電動機負載過重，使得直流電動機不能起動，現(xiàn)用提高電源電壓的方法使電機起動。（ X ）38、對水冷發(fā)電機定子反沖洗后，應(yīng)進行流量測定，測定流量的結(jié)果應(yīng)大于沖洗前的流量。（V ）39、為減少發(fā)電機附加損耗等，定子繞組將進行換位，通常換位方式有360°和540°換位。（V ）40、交流電動機功率越大，它的鐵心截面越大；鐵心截面積小，功率也越小，因此無銘牌的電動機需重新更換繞組時，必須計算出它的功率大小。（V ）41 、汽輪發(fā)電機標(biāo)準(zhǔn)化大修時，應(yīng)更換端部定子線棒。（ X ）42、異步電動機空載起動困難，聲音不均勻，

34、說明轉(zhuǎn)子籠條斷裂，而且有總數(shù)1 7 以上的數(shù)量斷裂。（V ）43、異步電機繞組在接線后，應(yīng)檢查繞組是否有接錯或嵌反，經(jīng)檢查無誤后，再用電橋測量三相繞組的直流電阻，其標(biāo)準(zhǔn)是各相相互差別不超過最小值的5%。 （ X ）44、 發(fā)電機定子端部線棒之間，當(dāng)同相相鄰的兩線棒電流同方向時，其間存在的相互作用力使它們相互壓擠靠攏，當(dāng)異相相鄰的線棒流過的電流方向相反時，則互相推開。（V ）45、 氫氣和二氧化碳氣管線安裝完后是否嚴(yán)密，在 300kPa 壓力下管道內(nèi)壓降在1h 內(nèi)不超過0.7kPa就可以認(rèn)為是嚴(yán)密的。（V ）46、發(fā)電機轉(zhuǎn)子護環(huán)瓦塊絕緣，一般有兩層，在拆裝時注意不錯裝上下層即可，不一定非要按原位

35、安裝，因各瓦塊基本大小一樣，不會影響轉(zhuǎn)子平衡。（ X ）47、維護整流子時，對整流子的開槽工作要特別仔細，最好是開U 型槽，深度一般為整流子云母片的厚度，而且要將截片邊緣處的棱角去掉。（V ）48、異步電動機的空載起動時間比原來增長了，但空載運行時，電磁聲仍比較正常，空載電流亦無明顯變化。當(dāng)帶負載后，電流波動，判斷是轉(zhuǎn)子鼠籠條有少量的斷裂。（V ）49、發(fā)電機轉(zhuǎn)子的懸掛式護環(huán)使用的彈性鍵，一般為開口鍵。在壓鍵前先找出鍵口位置，方法是可用敲打經(jīng)手感振動程度找出鍵口處。（V ）二 . 選擇題：1 、關(guān)于電流的認(rèn)識，正確的說法是（B ） 。（A）只有正電荷運動才能形成電流； （B）電流是由于帶電質(zhì)子

36、運動形成的；（C）自由電子總是從高電位流向低電位；（D）正電荷總是從低電位流向高電位。2 .下面說法正確的是（C ） 。ctivities,compre hensive andtamping SafetyFoundation .Troubleshooting,managementmechanism, givefull playtorol eoftechnical supervisi on a nd reali zation oftroubleshooti ng, manag ement,improv ed pr ocess manageme nt.Thi s yearcomplete d th
