當(dāng)小齒輪以3000rpm的轉(zhuǎn)速,而扭矩為20kg-m時(shí),傳遞至大齒輪的轉(zhuǎn)速便降低了1/3,變成1000rpm;但是扭矩反而放大三倍,成為60kg-m。這就是發(fā)動(dòng)機(jī)扭矩經(jīng)由變速箱可降低轉(zhuǎn)速并放大扭矩的基本原理。在汽車(chē)上,發(fā)動(dòng)機(jī)輸出至輪胎為止共經(jīng)過(guò)兩次扭矩的放大,次由變速箱的檔位作用而產(chǎn)生,第二次則導(dǎo)因于終齒輪比(或稱(chēng)終傳動(dòng)比)。 電流互感器正常運(yùn)行時(shí),二次側(cè)不準(zhǔn)開(kāi)路。電流互感器二次一旦開(kāi)路,二次電流I2=0,一次電流I1仍為線路負(fù)荷電流,數(shù)值很大。從而引起鐵芯飽和,磁通Φ劇增,將使鐵芯過(guò)熱,同時(shí)在二次線圈中產(chǎn)生幾千伏甚至上萬(wàn)伏的高電壓。
