课程名称：电气安装中的接地系统类型 课程概述：本课程帮助您理解并选择适合您电气安装的接地系统。课程通过3D视频展示，帮助您更好地可视化和理解相关内容。所有信息基于国际标准，适用于您所在国家的相应规定。课程中还将提供电动汽车供应设备的实践示例，并讲解有关接地系统的技术规格。 IEC 60364是国际电工委员会关于建筑物电气安装的国际标准，其中IEC 60364-1提供了电气安装的设计、施工和验证的规则。这些规则旨在确保在合理使用电气安装时，个人、牲畜和财产的安全，防止可能出现的危险和损害，并确保电气安装的正常运行。 课程还将解释导体的功能，例如PEN、PE和N等。PEN（保护接地中性线）是一个结合了保护导体（PE）和中性导体（N）功能的导体。PE导体为故障提供回路（当可接触导电部分变得有危险电压或发生接地故障时），而中性导体则连接到系统的中性点，并有助于电能的传输（电流流动的回路）。 通过本课程，您将能够掌握接地系统的选择和应用，为安全的电气安装打下基础。
This course helps you to understand and choose the right system earthing for your electrical installations.During this course there will be presented in 3D videos to help you to visualize and understand better about it.All the information is based on international standards so it can be applied for any country according to your national regulations.There will be presented practical example for Electric Vehicle Supply Equipment, also there will be explained the technical specifications concerning Earthing System. •IEC 60364 Electrical Installations for Buildings is the International Electrotechnical Commission's international standard on electrical installations of buildings.•IEC 60364-1 gives the rules for the design, erection, and verification of electrical installations.•The rules are intended to provide for the safety of persons, livestock and property against dangers and damage which may arise in the reasonable use of electrical installations and to provide for the proper functioning of those installations.Also, there will be explained the functions of conductors like PEN, PE, N etc.•PEN (protective earthed neutral) is the conductor which combines the functions of both protective conductor (PE) and neutral conductor (N).•The PE conductor provides the return path for the fault (when accessible conductive parts become hazardous-live or to line to earth fault).•Neutral conductor - a conductor connected to the neutral point of a system and contributing to the transmission of electrical energy (return path for the current flow).
