摘要
通过对电力变压器的运行状态进行简要介绍,说明变压器进行继电保护配置的必要性,进而分析了变压器的零序保护配置方式、动作时限和过负荷保护的整定方法与装设原则,具有一定的实用性和可靠性,为下一步研究变压器的后备保护系统配置及保护间的配合动作方式奠定了基础。
A brief introduction to the operation state of power transformers is given to illustrate the necessity of relay protection configuration.Then the zero-sequence protection configuration mode, time limit of operation and overload protection setting method and installation principle are analyzed.With a certain degree of practicality and reliability, it lays the foundation for the next step of studying the backup protection system configuration of transformers and the coordinated actions between protections.
