依據(jù)變壓器運作流程規(guī)定，在運作中的變壓器中性線電流不得大于變壓器低壓側(cè)額定電流的3%。此外，三相負(fù)載不均衡運作會構(gòu)成變壓器電流過大，部分金屬件溫度過高，可能會引起變壓器毀壞。對用電設(shè)備的作用：三相電壓不均衡的發(fā)生將引起達到數(shù)倍電流不均衡的發(fā)生，進而使電動機的溫度飆升，速率下降，能耗增多，輸出損耗導(dǎo)致用電設(shè)施使用年限縮短，提升設(shè)備維修的成本。變頻電源廠家在生產(chǎn)和制造方面，需要做到以下三點，這樣可以保證好產(chǎn)品的質(zhì)量，也才能夠使變頻電源更加長久的被用戶使用，才會深受大眾的喜歡。

但干燥搜術(shù)的這些特點往往被人有意或無意地忽視。制造廠商由于實驗裝置缺乏或機型不全（這在我國是一個普遍存在的現(xiàn)象）經(jīng)?；乇軕?yīng)做的干燥實驗，而用戶由于不了解干燥技術(shù)的特點，也經(jīng)常放棄進行必要實驗的要求。其結(jié)局是裝置使用效果不佳，甚至于造成方案設(shè)計失敗。在我國，這樣的事例屢見不鮮，曾有過一套價值2萬元人民幣的工業(yè)干燥裝置因達不到使用要求而被閑置的教訓(xùn)。建設(shè)工業(yè)干燥裝置尤其是較大的裝置之前，一定要進行充分的、有說服力的實驗，并以實驗結(jié)果作為工業(yè)裝置設(shè)計的依據(jù)。

儀器儀表的維修在電子市場中是不可缺少的一部分，儀器儀表公司只有憑借良好的檢測技術(shù)才能讓那些不合格的產(chǎn)品終合格的走進市場，對儀器儀表的技術(shù)員工要有著良好的電子專業(yè)知識基礎(chǔ)，也需要豐富的現(xiàn)場經(jīng)驗。升降溫法有時，儀表工作較長時間，或在夏季工作環(huán)境溫度較高時就會出現(xiàn)故障，關(guān)機檢查正常，停一段時間再開機又正常，過一會兒又出現(xiàn)故障。這種現(xiàn)象是由于個別IC或元器件性能差，高溫特性參數(shù)達不到指標(biāo)要求所致。使用中的常見問題分析布袋除塵器出口粉塵排放量超標(biāo)(排放口冒黑煙),污染環(huán)境,而且浪費能源,達不到環(huán)保要求,表現(xiàn)為布袋除塵器效率低。常因布袋除塵器乏氣流量受限,達不到額定值,導(dǎo)致制粉系統(tǒng)出力下降,制粉電耗增加。布袋易失火,嚴(yán)重影響機組安全經(jīng)濟運行。布袋除塵器箱體低溫腐蝕嚴(yán)重,布袋壽命短,檢修維護工作量大,維護費用高。常見問題產(chǎn)生原因分析一般來講，導(dǎo)致布袋除塵器難以正常運行而常發(fā)生上述故障的因素較多,但主要有以下幾方面原因：由于布袋高耐溫能力為15e,運行調(diào)整不佳或布袋積粉自然均會導(dǎo)致布袋著火燒毀。
