變壓器是一種相對靜止的電氣設備，由繞在同一個鐵心上的兩個或兩個以上的繞組組成的，繞組之間通過交變的磁通的相互聯(lián)系。為了把發(fā)電廠發(fā)出的電能經(jīng)濟的傳輸、合理的分配以及安全的使用，都要用到電力變壓器。 </p> <p> 2、變壓器工作原理 </p> <p> 簡單說變壓器的工作原理就是“電生磁，磁生電”。變壓器的初級（一次）線圈和次級（二次）線圈共同繞在一個鐵芯上，當一次線圈通入電壓U1后，在鐵芯中產(chǎn)生交變磁通，這個磁通穿過一次繞組和二次繞組，根據(jù)電磁感應定律，在一次繞組和二次繞組中分別產(chǎn)生感應電勢E1和E2。根據(jù)電磁感應定律可知，一次側(cè)、二次側(cè)繞組的感應電勢分別為：E1/E2=U1/U2=N1/N2=K(k為變比) </p> <p> <br /> </p><p style="text-indent:25px">變壓器是借助于電磁感應,在繞組之間交換交流電壓或電流的一種電氣設備。從電廠發(fā)出的電能,要經(jīng)過很長的輸電線路輸送給遠方的用戶，為了減少輸電線路上的電能損耗,必須采用高壓或超高壓輸送。而目前一般發(fā)電廠發(fā)出的電壓,由于受到絕緣水平的限制，電壓不能太高,這就要經(jīng)過變壓器將電廠發(fā)壓進行升高送到電力網(wǎng)。這種變壓器統(tǒng)稱升壓變壓器。對各用戶來說,各種電氣設備所要求的電壓又不太高,也要經(jīng)過變壓器，將電力系統(tǒng)的高電壓變成符合用戶各種電氣設備要求的額定電壓。作為這種用途的變壓器統(tǒng)稱降壓器。電力變壓器是電力系統(tǒng)中，用以改變電壓的主要電氣設備。正是因為變壓器的存在才能夠讓我們的電壓即便在天氣惡劣的時候也是非常的穩(wěn)定。</p><div

src="https://tyunfile.71360.com/UploadFile/ZRX888/637284368225537109/2074462.png"></div><p> 變壓器的參數(shù)有勵磁參數(shù)和短路參數(shù),只有已知參數(shù),才能運用前面所介紹的基本方程式、等值電路或相量圖求解各量。對制造好的變壓器,其參數(shù)可通過實驗測得。 </p> <p> 空載實驗目的:通過測量空載電流和一、二次電壓及空載功率來計算變比、空載電流百分數(shù)、鐵損和勵磁阻抗。 </p> <p> 1.低壓側(cè)加電壓,高壓側(cè)開路，為了便于測量和安全,空載實驗一般在低壓繞組上加電壓,高壓繞組開路。 </p> <p> 2.空載電流和空載功率必須是額定電壓時的值，并以此求取勵磁參數(shù)； </p> <p> 3.若要的達到高壓側(cè)參數(shù)須折算。 </p> <p> <br /> 對于特高電壓等級的輸變電設備，沖擊耐壓試驗是非常重要的例行試驗。中山變壓器的好壞測試</p><p style="text-indent:25px">在變壓器的日常維護時需要注意觀察外觀，主要檢查變壓器外部是否存在滲油、是否存在零部件冒煙或放電現(xiàn)象。成都電子變壓器故障檢測儀</p><p> 綜合測試的目的是保證產(chǎn)品其本性能的一項測試試驗。耐壓測試的目的是為了防止產(chǎn)品在正?；虿皇褂脳l件下發(fā)生漏電、電擊、火災等事故危及消費者的生命財產(chǎn)安全而采取的一項安全測試試驗。耐壓儀器在使用過程中必須墊絕緣膠皮，測試人員測試時，所在座位底板必須要墊絕緣膠皮。測試人員測試時，必須戴絕緣手套。測試時嚴禁接觸治具導電體，接觸高壓會對人體造成損傷。 </p> <p> 綜合測試儀日常維護注意事項： </p> <p> 1.為保證測試精確測試,開機預熱時間應不少于15分鐘。 </p> <p> 2.請勿頻繁開關(guān)儀器,以引起內(nèi)部數(shù)據(jù)混亂,造成測試不準確。 </p> <p> 3.不可帶電插撥測試連接線。 </p> <p> 4.遠離磁場。 </p> <p> 5測試前清洗測試治具。 </p> <p> 6.常規(guī)7S檢查。 </p> <p> 7待機狀態(tài)時將儀器退出掃描測試。 </p> <p> <br /> 成都電子變壓器故障檢測儀</p><p
