| 摘 要： | 根据试验和分析表明,配电网中性点经高电阻接地能有效地限制弧光接地过电压、断线过电压等各种谐振过电压,防止串联谐振,易于实现选择性的继电保护。在可靠性、安全性和经济性等方面,高电阻接地有较明显的优势。高电阻接地还可以在较大范围推广应用。

| Abstract: | The test and analysis indicates that the ground of the neutral point in the distribution power network through the high resistors can effectively limit various resonance over voltage, including the arc ground, single-phase-switch and others to protect the network from serial resonance and realize selective relay protection. The high resistance ground has obvious advantages in reliability, safety and economy, which is worth to be popularized in awider scope. |
