摘　　要：吉林省电网内66 kV及220kV微机型变压器保护近来正确动作率较低。通过对其配置、设计、验收和运行维护等情况的调查,对其存在型号过多、原理缺陷、无统一标准等问题的分析,提出了从设备选型、设计到投产验收实施全过程监督等整改措施。Operation accuracy of microprocessor-based protection in Jilin province was a little lower than before. This paper analyzed various of types of transformer microprocessor-based protection, imperfections on protection principle, no unified criteria and personnel in protective relaying etc. , and proposed rectification of whole process supervision from device type selection, design to put into production and acceptance.
