课程名称：空气绝缘变电站设计 第三部分 课程概述：空气绝缘变电站是电力网络中最常见的变电站类型，因为其成本效益高且结构简单。在本课程的第三部分，我们将探讨这种类型变电站的一些附加特征。大多数变电站使用直流电（DC）为保护和控制系统供电，以便在主交流电（AC）供应失败时，仍然能够监控和控制电力网络。本课程将讲解您在典型的传输级变电站中会遇到的所有直流系统。 在本课程的第二部分中，我们讨论了基本的联锁系统，而在这一部分课程中，我们将引入一些更高级的原则，这是这一重要系统特征的关键。保护面板用于容纳我们使用的所有保护和控制设备，研究它们的构造以及其中包含的一些设备（其中一些仅出现在保护系统中）将非常有趣。 电流互感器（CT）在变电站中用于测量电流的大小，在本课程中，我们将展示它们的所有关键特性以及在正常和故障情况下的操作方式，这将帮助您理解电流互感器额定板上所有的参数。与电流互感器相似，我们还将学习电压互感器的工作原理以及它们如何连接到二次保护系统。 通过本课程的学习，您将更好地理解这些关键变电站系统的各个方面。
Air insulated substations are the most common type of substation that you will find on the electrical network, due to their cost effectiveness and simplicity.In part 3 of this course we will look at some additional features of this type of substation. Most substations use DC to supply the protection and control systems, so that when the main AC supply fails we can continue to monitor and control the electrical network, In this course we will look at all of the DC systems that you will come across inside a typical transmission level substation.In part 2 of this course we looked at basic interlocking, in this course we introduce some more advanced principles of this important system featureProtection panels are used to house all of the protection and control equipment's that we use, and it is interesting to study how they are constructed, and look at some of the equipment's that they contain, some of which only appears in protection systems.Current transformers are used in the substation to measure the magnitude of the current, in this course we will show all of their key features and how they operate during normal and fault situations, this will allow you to understand all of the parameters that you will find on a CT rating plate.In the same way as we looked at current transformers we will learn how voltage transformers operate and how they should be connected to the secondary protection system.By the end of the course you will have a better appreciation of all of these key substation systems.
