摘 要

本次课程设计的题目是《35kV主变压器保护初步设计》。根据设计的要求，在设计的过程中，用到了35kV降压变电站的绝大多数的基础理论和设计方案，因此在设计过程中侧重了知识系统化能力的培养。设计可分为几部分：主变压器保护的配置，主变压器继电保护的整定计算以及保护回路接线图的绘制。

通过本次设计，学习了设计的基本方法，巩固三年以来学过的知识，培养独立分析问题的能力，而且加深对变压器继电保护的全面了解。

关键词： 继电保护 保护配置 整定计算 保护回路

Abstract

The course design is the subject of 35kV preliminary design of main transformer protection. According to the design requirements，use the 35kV step-down substation for the vast majority of the fundamental theory and design. Therefore in the process of design focus on the knowledge system of ability training. The design can be divided into several parts: Main transformer protection configuration, main transformer relay protection setting calculation and protection circuit wiring diagram.

By the design, learning the basic design method, the consolidation of the three years since the learned knowledge, cultivate the independent ability to analyze the problem, and to deepen the understanding of transformer relay protection.

Key Words: Relay protection; Protection configuration; Setting calculation; Protection circuit
