在電動機停止運行時，要定期（每月）用絕緣表測量其各相對地或相間絕緣電阻，并與上月測試結(jié)果相比較，以便及時發(fā)現(xiàn)絕緣缺點，發(fā)現(xiàn)不良時用烘潮燈烘烤以提高絕緣，避免因絕緣太低（推薦值>1兆歐）擊穿繞組燒壞電動機。沒有烘潮電加熱的電動機除非特殊情況，不要隨意關掉加熱開關。在潮濕天氣和冬季時要特別注意電動機的防水、防潮和烘干。對露天及潮濕場所的電動機要特別注意水密，對懷疑嚴重受潮或濺過水的電動機，使用前更應認真檢查。如果發(fā)現(xiàn)電動機浸泡水，只要將電動機解體后抽出轉(zhuǎn)子，并用壓縮空氣吹干后，再用烤燈從電動機定子內(nèi)兩端烘烤，直止電動機絕緣升至正常。河南三相異步電機維修聯(lián)創(chuàng)電機不懈追求產(chǎn)品質(zhì)量，精益求精不斷升級。</p><div

吊入式機座是一個長方體的箱式結(jié)構(gòu)，機座內(nèi)部軸向有筋，用于支撐和固定定子。定子是從上方放入機座，靠定子壓圈與機座軸向筋定位并保證氣隙均勻度。再用螺栓將定子與機座緊固。機座端端板的內(nèi)止口與端蓋的外止口緊密配合，能充分保證定、轉(zhuǎn)子之間的氣隙均勻度。壓入式機座大多是通過熱套方式將定子套入機座，該方式下機座與定子的同心度容易保證，但相對與吊入式機座便捷性要遜色一些。 </p> <p> ● 定子線圈：定子線圈是雙層疊繞阻，絕緣等級為F級，電壓等級為3KV及以上的電機都有防電暈措施。 </p> <p> ● 轉(zhuǎn)子線圈：繞線電機的轉(zhuǎn)子線圈是雙層波繞組，采用矩形銅排，絕緣等級要求為F級。 </p> <p> ● 定子：定子通常采用磁性槽楔，根據(jù)需要也可用非磁性槽楔。線圈端部之間應采用適型材料墊緊，并與端箍、支撐桿扎牢在一起，經(jīng)過真空壓力整浸無溶劑漆后，整個定子成為一個整體，增強了其機械性和防潮能力。<span style="display:none;"></span> </p> <p> ● 轉(zhuǎn)子：鼠籠型電機一般情況下采用鑄鋁轉(zhuǎn)子，這種轉(zhuǎn)子運行可靠，并具有較好的起動性能，它可以滿壓直接起動。根據(jù)需要也可采用銅條轉(zhuǎn)子，銅條轉(zhuǎn)子電機效率相對較高，但成本也要高好多。 </p> <p> ● 軸大多焊有輻板，并經(jīng)過熱處理，具有較好的機械性能。高壓電機軸的熱處理非常關鍵，稍有不慎，會出現(xiàn)斷軸問題。 </p><p style="text-indent:25px">作為電動機運行是同步電機的另一種重要的運行方式。同步電動機的功率因數(shù)可以調(diào)同步電機節(jié)，在不要求調(diào)速的場合，應用大型同步電動機可以提高運行效率。小型同步電動機在變頻調(diào)速系統(tǒng)中開始得到較多地應用。同步電機還可以接于電網(wǎng)作為同步補償機。這時電機不帶任何機械負載，靠調(diào)節(jié)轉(zhuǎn)子中的勵磁電流向電網(wǎng)發(fā)出所需的感性或者容性無功功率，以達到改善電網(wǎng)功率因數(shù)或者調(diào)節(jié)電網(wǎng)電壓的目的。同步發(fā)電機和其它類型的旋轉(zhuǎn)電機一樣，由固定的定子和可旋轉(zhuǎn)的轉(zhuǎn)子兩大部分組成。一般分為轉(zhuǎn)場式同步電機和轉(zhuǎn)樞式同步電機。聯(lián)創(chuàng)電機品質(zhì)好、服務好、客戶滿意度高。</p><div

根據(jù)實際而定方式:電機容量大小與電源容量且1000KW以下的可直接啟動,這時的沖擊電流是額定值的3-6倍.為了防止沖擊電流過大,對于大電機必須考慮減少啟動電流的啟動方式:有串電抗啟動,變頻啟動,液力偶合器啟動等多種方式.有復雜有簡單,價錢差異很大. 由于電壓高,電流沖擊大,電機制造必須滿足過電壓的要求,絕緣等級要求較高。 </p> <p> <p> ● 在安裝現(xiàn)場核對電動機廠裝箱清單中的所有項目。 </p> <p> ● 在基礎臺上確定位置標記以便找出機組的中心線及基礎面的標高。 </p> <p> ● 按電動機的外形圖核對基礎以確定地坑、電纜、電纜管道，匯流排或所需的通風管道都已齊備并放置在適當?shù)奈恢蒙?。并且有足夠的地方進行機組及其附件的安裝。 </p> <p> ● 按圖核對基礎螺栓尺寸，位置及螺栓頂部的標高。 </p> <p> ● 準備好足夠數(shù)量的校平用墊板及墊片以確保底板或底架放置其上時，底板或底架不會變形。這些墊板的厚度約為8毫米、寬度約120毫米，長度應比電動機底板或底架每邊伸出約60毫米。 </p> 聯(lián)創(chuàng)電機以質(zhì)量求生存，以信譽求發(fā)展！濟寧大型電機型號</p><p

旋轉(zhuǎn)電機的故障和損壞大部分是由于繞組絕緣的損壞而引起的,其中繞組的匝間絕緣占50%左右,而且一旦損壞后果將是嚴重的。匝間絕緣短路基本上是由于電機在各種過電壓作用下匝間沖擊電壓值超過部分繞組匝間絕緣的工作電壓造成的,有一部分是線圈和繞組在制造過程中的機械損傷造成的,另外還有高壓電機繞組內(nèi)部間隙所產(chǎn)生的局部放電、高壓繞組的電暈腐蝕所引起的。上述因素引起的損壞都直接或間接與電機所用的繞組線性能有關。隨著旋轉(zhuǎn)電機的更新?lián)Q代,各種特種電機和耐高溫電機的需要,開發(fā)新型的繞組線勢在必行。河南三相異步電機維修</p><p
