摘要
本文结合某超高层住宅的配电设计实例,依据现行设计规范的要求,探讨保证间接接触保护有效性的充分及必要条件。通过推导计算和资料整理,为工程设计提供简明实用的速查表格及简化公式。
Combining with the example of a super high- rise residential power distribution design,according to the current design requirements,The paper is exploring how to guarant the sufficient and necessary conditions for indirect contact protection effectiveness. Through calculation and data collection,the simplified formula and a concise practical lookup table are provided for engineering design.
