接地装置在电气系统中起着保护设备及人身安全的重要作用,因此,它的施工质量好坏,直接影响着电气系统的安全运行。下面就电气安装工程中接地装置的常见质量通病进行总结并提出防治对策,供广大电气施工人员参考。 1.电气装置的接地质量通病 1)接地极的安装不统一,地极材料选用不规范,焊接质量低劣,夹渣气孔、焊瘤等缺陷。 2)接地极引出扁铁的做法不一,断接卡的安装方法不规范。
Grounding device in the electrical system plays a protective equipment and personal safety an important role, therefore, its construction quality is good or bad, a direct impact on the safe operation of the electrical system. The following electrical installation of grounding devices in the common quality of common problems and prevention and control measures proposed for the majority of electrical construction workers for reference. 1. Grounding quality of electrical devices common problem 1) the grounding of the installation is not uniform, non-standard choice of materials, poor welding quality, slag inclusions, welding defects. 2) grounding leads to different ways of flat iron, broken card installation method is not standardized.
