接地干式变压器

　　接地变压器的作用是为中性点不接地的系统提供一个人为的中性点，便于采用消弧线圈或小电阻的接地方式，以减小配电网发生接地短路故障时的对地电容电流大小，提高配电系统的供电可靠性。

　　The function of the grounding transformer is to provide an artificial neutral point for a system with an ungrounded neutral point, facilitating the use of arc suppression coils or small resistors for grounding, thereby reducing the capacitive current to ground during a ground short circuit fault in the distribution network and improving the power supply reliability of the distribution system.
