细导线连接质量的电气测试

摘要

Large numbers of 6 mm2 or below wires are connected in electrical end lines of buildings, and their connection quality directly affects electrical safety. In accordance with relevant standards and regulations and with reference to site engineering conditions, this paper discusses methods and operation steps of evaluating wire connection quality based on DC resistance, loop circuit impedance and circuit voltage drop which are measured on site.%建筑电气末端线路工程中存在大量6 mm2及以下导线的连接，其连接质量直接影响用电安全。根据相关标准规范，并考虑工程现场条件，提出采用现场测量直流电阻、环路阻抗、回路电压降，评估导线连接质量的方法与操作步骤。
