课程名称：电力三相变压器基础 课程概述：本课程将深入研究电磁力如何与带电粒子及电磁场相互作用，并如何导致电压和电流的转化。内容涵盖变压器的比率与极性，介绍了潜变压器和电流变压器以及它们与相关仪器（如电流计、电压计、功率计和能量计）的使用。课程还包括变压器核心结构，损耗及冷却缓解技术。学习三相变压器的配置，以及谐波失真、CT饱和和负载调节开关问题，并探讨如何解决这些问题。此外，还涉及了过电流和限制差动变压器保护，并回顾了一些“传统继电器”及现代智能电气设备（IDE）继电器的实例。变压器连接方式（Y - Y；Δ - Δ；Y - Δ；Δ - Y 及 Y - Zag Zig）将被仔细研究，同时也将学习变压器钟表系统向量命名法。课程话题包括油分析和布赫霍兹继电器的应用。 本课程旨在为学员提供变压器工作原理的深刻理解以及在实际应用中的重要知识。通过系统的学习，学员将能够掌握变压器的设计、建造和应用技巧。
Electromagnetic forces interact with electrically charged particles and electromagnetic fields; this course will study how these forces lead to voltage & current transformation. Ratios and polarity is also studied leading to the introduction of potential transformers & current transformers, and their use in conjunction with the relevant instruments such as ammeters, voltmeters, watt meters and energy meters. Transformer core construction along with losses & cooling mitigation techniques. 3 phase transformer configurations are studied along with harmonic distortion, CT saturation and on-load tap-changer problems and how these problems are dealt with. Over-current and restraint differential transformer protection is developed along with a look at some examples of " Old School relays" as well as modern IDE (intelligent Electrical Devices) relays.Transformer Connections: (Y - Y; Delta - Delta; Y - Delta; Delta - Y & Y - Zag Zig) are examined along with Transformer Clock System Vector Nomenclature.Oil Analysis and the Buchholz Relay are also studied.
