众所周知,正常情况下,电气设备的外壳并不带电,当拥有电气设备的绝缘结构损坏后,电流会通过金属外壳,此时如果人触碰金属外壳可能遭到电击,我国就曾发生过多起电气设备外壳漏电而引发的触电事故。现阶段,人们的防触电意识越来越强,建筑电气施工中的接地与接零装置受到了愈来愈多人的关注,人们通过为电气设备安装接零与接地装置而有效地降低了电气设备漏电的风险,最大程度地保障了用电安全。本文主要探讨了建筑电气施工中接零和接地的施工技术。
As we all know, under normal circumstances, the electrical equipment is not charged shell, when the electrical equipment has damaged the insulation structure, the current will pass through the metal shell, then if people touch the metal shell may be subjected to electric shock, China has had too many Electrical equipment shell leakage caused by electric shock accident. At this stage, people’s awareness of electric shock is getting stronger and stronger, people pay more and more attention to the grounding and zero-connection devices in the electrical construction of buildings, and people reduce the electrical efficiency effectively by installing zero and grounding devices for electrical equipment Equipment leakage risk, to maximize the protection of electricity safety. This article mainly discusses construction technology of connecting zero and grounding in construction electrical construction.
