| 摘要: |
| 针对国电公司《反措》25条实施细则及继电保护规程，提出了大型发电机变压器组成套保护双重化配置的原则，涉及电流互感器及电压互感器配置的基本原则，并介绍了两种典型的配置方案。接着提出了发电机变压器组保护双重化配置方案、保护组柜原则，提出了有意义的建议，同时指出了《规程》、《反措》中的不足和矛盾。希望将有关原则纳入修编的继电保护和安全自动装置技术规程。 |

| Abstract: |
| According to the twenty-five instructions about anti-accident measures and the technical code for relaying protection and security automatic equipment ,the redundant configuration principle of ganged protection for utility-type generation-transformer unit is put forward,including the basic design criteria of CT and PT.After two typical configuration schemes are introduced,the redundant configuration of generation-transformer unit protection and the relay cabinet arrangement principle are presented.The deficiency and contradictio n in the Code and Measures are pointed out ,the rela-tive problems are explained,and the senseful suggestions are proposed.Authors hop e that the revised edition of the technical code for relaying protection and security automatic equipment should adopt these principles. |
