| 供配电系统的中性点接地方式指的是变压器星型绕组中性点与大地的电气连接方式，我国的电力系统按照中性点接地方式的不同可划分为两大类：大电流接地方式和小电流接地方式。 The neutral grounding mode of power supply and distribution system refers to the electrical connection between the neutral point of transformer star winding and the earth. According to the difference of neutral grounding mode, the power system in China can be divided into two categories: high current grounding mode and low current grounding mode. 简单地说大电流接地方式就是指中性点有效接地方式，包括中性点直接接地和中性点经低阻接地等。小电流接地方式就是指中性点非有效接地方式，包括中性点不接地、中性点经高阻接地和中性点经消弧线圈接地等。 Simply speaking, high current grounding means effective grounding of neutral point, including direct grounding of neutral point and low resistance grounding of neutral point. The low current grounding means that the neutral point is not grounded effectively, including the neutral point is not grounded, the neutral point is grounded by high resistance and the neutral point is grounded by arc suppression coil. |
