摘　　要：就变压器外部相间短路时变压器保护的配置方案进行了研究,认为必须通过继电保护整定计算分析,才能科学地确定保护配置方式,并列出了各种保护方式在工程实际中的一些简化整定计算方法。The author makes a study on the arrangement of relay protections in external interphase short circuit of a transformer and concludes that only when the setting calculation and analysis of relay protections are made, the arrangement method can be determined scientifically. In the meanwhile, some simplified setting calculation methods for various protections in engineering practices are given in the paper.
