style="text-indent:25px">變壓器容量測(cè)試儀包括兩個(gè)方面。一種是磁滯損耗。當(dāng)交流電流通過(guò)變壓器時(shí)，硅鋼板通過(guò)變壓器的磁力線的方向和大小會(huì)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(gè)是變壓器工作時(shí)的渦流損耗。有一條磁力線穿過(guò)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。</p><p style="text-indent:25px">什么是短路試驗(yàn)？短路是指電路中的一部分被短接，短路試驗(yàn)也稱為變壓器負(fù)載試驗(yàn)或者是負(fù)載損耗試驗(yàn)，是測(cè)量變壓器額定電流下的短路損耗和阻抗電壓。短路試驗(yàn)測(cè)量方法：測(cè)量時(shí)，使用DCBS-S變壓器損耗參數(shù)測(cè)試儀將低壓短路，高壓側(cè)輸入電源，通過(guò)手動(dòng)或自動(dòng)施加電壓（低壓線圈中的電流達(dá)到他的額定電流時(shí)的高壓電壓），除以高壓的額定電壓，我們就得到了阻抗電壓百分比，此時(shí)低壓和高壓線圈的電流都達(dá)到額定值，即可得到變壓器的負(fù)載損耗（銅損）值。變壓器直流電阻測(cè)試儀的測(cè)量和放電是其常用的功能，需要電力工人的熟練操作。</p><div
