课程名称：空气绝缘变电站设计第二部分 课程概述：空气绝缘变电站是电网中最常见的变电站类型，因其 cost-effective（成本效益高）和 simplicity（简单性）而广受欢迎。在本课程的第二部分，我们将探讨这种变电站的一些附加特性。课程的主要焦点是变压器，我们将学习其基本原理，包括变压器的额定值、构造和设计，并了解如何设计变电站以整合这些关键设备。 在变电站中，每个断路器、隔离器和其他开关设备都必须有一个独特的编号，以避免混淆并确保变电站安全运行。我们将学习如何从基本原则出发开发一个编号系统，并将其应用于各种变电站配置。 在变电站内部，由于 interlocking（联锁）机制的使用，确保主要设备只能以安全的顺序操作，从而确保接地设备不会在带电系统下激活，并且在其设计参数内运行。我们将研究两种主要的联锁形式：机械联锁和电气联锁，并查看它们如何应用于各种常见的变电站配置。 环网单元在整个电力网络中广泛使用，我们将研究这些关键设备的使用和操作方式，以改善电力网络的安全性。 通过本课程的学习，您将更好地了解这些关键变电站系统。
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 2 of this course we will look at some additional features of this type of substation. The main with focus will be on transformers, we will learn all of the fundamental principles behind them including their rating, construction & design and them see how we design a substation to incorporate these critical equipments.In substations it is essential that all circuit breakers, isolators and other switchgear each has a unique number to avoid confusion and ensure that the substation is operated safely. We will learn how a numbering system can be developed from first principles and how it can applied to various substation configurations.Interlocking is used inside substations to ensure that primary plant can only be operated in a safe sequence, which ensures that grounded equipment is never energised from the live system and within its design parameters. We will look at the two main forms of interlocking, namely mechanical & electrical, and see how they can be applied to various common substation configurations.Ring main units are used throughout the electrical network and we look at how these critical equipments are used and operated to improve the security of the electrical network.By the end of the course you will have a better appreciation of all of these key substation systems.
