摘　　要：随着人们生活水平的不断提高,对电力资源的需求量在不断加大,为了实现电力资源的可持续供给,电力系统普遍采用了高压输电线路,并且加大了变压器的容量,这就要求给予变压器更多的保护,避免其在运行过程中出现故障问题。而1000 kV特高压主变压器中的参数设置与构建特点互不相同,故应根据其运行特点,采取特定的差动保护装置,实现对特高压主变压器的良好保护,确保社会发展对电力资源的需求。People’s living standards continue to increase,and the demand for power resources is increasing.In order to achieve sustainable supply of power resources,high-voltage transmission lines are commonly used in power systems,and transformers are also increased.Capacity,which requires that the transformer should be given more protection to avoid failure problems during its operation.The parameter setting and construction characteristics of the 1000 kV UHV main transformer are different from each other,so a specifi c differential protection device should be adopted according to its application characteristics,so as to achieve good protection of the UHV main transformer operation and ensure that it meets The demand for power resources for social development.
