摘要
分析了GB 13955—1992、GB 13955—2005、GB 14050—2008对TN、IT系统的低压电网接地型式的规定,其文字和电路图描述不一致,甚至自相矛盾。阐述了对低压电网接地型式的要求、建议。提出了对系统接地安全技术要求的意见。
Based on GB 13955--1992, GB 13955--2005, GB 14050--2008, this paper analyzed the connection types of TN, IT systems for low voltage power grid. It was found that the text description and circuit diagrams were inconsistent and even contradictory. The connection type requirements and suggestions of low voltage power grid were elaborated. The safety technical requirements of ground system were proposed.
