style="text-indent:25px">變壓器容量測試儀包括兩個方面。一種是磁滯損耗。當交流電流通過變壓器時，硅鋼板通過變壓器的磁力線的方向和大小會相應(yīng)改變，從而使硅鋼板內(nèi)部的分子彼此摩擦，釋放出熱能，從而損失電能的一部分，稱為磁滯損耗。另一個是變壓器工作時的渦流損耗。有一條磁力線穿過鐵芯，并且在垂直于磁力線的平面上將產(chǎn)生感應(yīng)電流。由于該電流形成循環(huán)回路并形成渦流，因此稱為渦流。渦電流的存在導(dǎo)致鐵芯發(fā)熱并消耗能量。這種損耗稱為渦流損耗。變壓器的效率與變壓器的功率水平密切相關(guān)。通常，功率越大，損耗與輸出功率之比越小，效率越高。相反，功率越低。變壓器測試儀器是用于變壓器容量、空載、負載等特性參數(shù)測量的高精密儀器。安微變壓器綜合參數(shù)測試系統(tǒng)</p><p

style="text-indent:25px">現(xiàn)在國內(nèi)外試驗變壓器均采用機械式的辦法進行調(diào)制和解調(diào)產(chǎn)生**頻信號，所以存在正弦波波形不標準，測量誤差大，高壓部分有火花放電，設(shè)備笨重，而且正弦波的二，四象限還需要大功率高壓電阻進行放電整形，所以設(shè)備的整體功耗較大。從國內(nèi)外多年的理論和實踐證明，用0.1Hz**頻耐壓試驗替代工頻耐壓試驗，不但能有同樣的等效性，而且設(shè)備的體積大為縮小，重量大為減輕，理論上容量約為工頻的五百分之一，且操作簡單，與工頻試驗相比優(yōu)越性更多。成都電子變壓器綜合性能測試</p><p
