    首先，通過對電壓互感器二次壓降的形成機理進行分析，得出以下關於二次壓降的相關結論： 1 、電壓互感器二次壓降等於二次迴路阻抗和迴路電流的乘積； 2 、電壓互感器二次迴路阻抗分為元器件自身阻抗和接觸阻抗兩部分，且接觸阻抗佔主要部分，從而使得電壓互感器二次迴路阻抗具有動態特性，而且具有一定的隨機性； 3 、電壓互感器二次迴路電流與二次負荷和迴路阻抗大小相關，因而二次迴路電流也是變化的； 4 、電壓互感器二次壓降是一個變化量，且具有單向性和一定的隨機性。
  4. It will effect the system in safety and running economy directly > test of tradition past the method is an usage to give or get an electric shock the bridge method or direct current to press to decline the method to proceed to measure, and the electric current for producing of is only in the ma class which ca n ' t broke through the oxidize surface

    高壓斷路器是電力系統中最重要的控制和保護設備之一，它對系統的安全、經濟運行有著直接的影響。以前傳統的測試方法是使用電橋法或直流壓降法進行測量，所產生的電流僅在ma級，不能擊穿觸頭氧化膜。
  5. The principle of ac - dc - ac locomotive is that transformer transforms the high single - phase ac voltage from contact system to lower ac voltage first, then rectifier transforms this ac voltage to steady dc voltage, finally converter transforms this dc voltage to three - phase vfvv ac voltage as the voltage source for asynchronous machine

    交?直?交型電力機車系統的原理是：先將從接觸網獲得的單相交流高電壓經變壓器降壓后，再經整流器變換為平穩的直流電壓，直流電壓經逆變器變換為三相交流電壓，供給機車輪對上的牽引電機。
