| 我国电力系统常用的中性点接地方式有：中性点直接接地、中性点不接地、中性点经消弧线圈接地（谐振接地）、中性点经电阻接地这四种方式。电力系统接地运行方式涉及电网的安全运行、供电可靠性、用户用电安全等诸多重要问题。在专业技术方面涉及电力系统、过电压与绝缘配合、继电保护、通信与自控、电磁兼容、接地设计等诸多领域，是一个内容广泛的系统问题。 The commonly used neutral grounding modes in China's power system are: neutral point direct grounding, neutral point ungrounded, neutral point through arc suppression coil grounding (resonant grounding), neutral point through resistance grounding four ways. The grounding operation of power system involves many important problems, such as the safe operation of the power grid, the reliability of power supply, and the security of the users. In terms of professional technology, it involves many aspects, such as power system, overvoltage and insulation coordination, relay protection, communication and automatic control, electromagnetic compatibility, grounding design, and so on. |
