| 摘要: |
| 针对现有主变保护在配置和整定上存在的问题，结合安徽省微机变压器保护典型设计的保护配置方案，深入讨论了典型设计中各保护配置的目的，特点及整定原则，特别是在主变高低压侧后备保护的选配方面，有其独到之处，并对变压器的运行方式，TA断线闭锁的投退作了一些探讨。详尽介绍了为使微机变压器保护装置便于运行及维护所采取的具体措施及改进办法。 |

| Abstract: |
| According to the existing problems in the configuration and setting of transformer protection ,and combined with its typical configuration design of Anhui province,the aim,features and setting principles of different protection configurations are deeply discussed.The choosing and configuration of the backup protection at both HV and LV sides of main transformer are especially presented.The transformer operation modes and the on-off of TA's line-break interlock are discussed.In order to make the computer transformer protections more convenient in operation and maintenance,the concrete measures and improving ways are introduced in detail. |
| Key words: transformer protection,typical design,configuration and setting, |
