随着我国经济建设的不断深入,电力系统建设也逐渐完善,并且已经逐渐走上现代化的道路,其中大型电力变压器是整个电力系统中的核心部分.但是,一旦主变近区发生短路现象则会对其正常运行产生不利影响,甚至导致整个电力系统瘫痪,因此进行主变近区短路后的电气试验及诊断的研究十分必要.%With the deepening of China's economic construction, the construction of the power system is gradually perfected, and has gradually embarked on the path of modernization, the large power transformer is the core part of the whole power system. However, once the main transformer near the short circuited will adversely affect its normal operation, and even lead to paralysis of the entire study on the electrical power system, so the test and diagnosis of the area near the main circuit becomes very necessary.
