1、西安科技大学高新学院外文翻译 1 西安科技大学高新学院 毕业设计 （ 论文 ） 外文翻译 学生姓名： 院（系）： 专业班级： 指导教师： 完成日期： 西安科技大学高新学院外文翻译 2 西安科技大学高新学院外文翻译 1 第 1 页 共 11 页 Relay protection development present situation Abstract reviewed our country electrical power system relay protection technological development process, has outlined the microcom

2、puter relay protection technology achievement, proposed the future relay protection technological development tendency will be: Computerizes, networked, protects, the control, the survey, the data communication integration and the artificial intellectualization. Key word relay protection present sit

3、uation development， relay protections future development 1 relay protection development present situation The electrical power system rapid development to the relay protection proposed unceasingly the new request, the electronic technology, computer technology and the communication rapid development

4、 unceasingly has poured into the new vigor for the relay protection technology development, therefore, the relay protection technology is advantageous, has completed the development 4 historical stage in more than 40 years time. After the founding of the nation, our country relay protection discipli

5、ne, the relay protection design, the relay manufacture industry and the relay protection technical team grows out of nothing, has passed through the path in about 10 years which advanced countries half century passes through. The 50s, our country engineers and technicians creatively absorption, the

6、digestion, have grasped the overseas advanced relay protection equipment performance and the movement technology , completed to have the deep relay protection theory attainments and the rich movement experience relay protection technical team, and grew the instruction function to the national relay

7、protection technical teams establishment. The acheng relay factory introduction has digested at that time the overseas advanced relay manufacture technology, has established our country relay manufacturing industry. Thus our country has completed the relay protection research, the design, the manufa

8、cture, the movement and the teaching complete system in the 60s. This is a time which the mechanical and electrical relay protection prospers, was our country relay protection technology development has laid the solid foundation. From the end of the 50s, the transistor relay protection was starting

9、to study. In the 60s to the 80s in are the times which the transistor relay protection vigorous development and widely uses. Tianjin University and the Nanjing electric power automation plant cooperation research 500kv transistor direction high frequency protection the transistor high frequency bloc

10、k system which develops with the Nanjing electric power automation research institute is away from the protection, moves on the Gezhou Dam 500 kv line , finished the 500kv line protection to depend upon completely from the overseas import time. From the 70s, started based on the integration operatio

11、nal amplifier integrated circuit protection to study. Has formed the complete series to at the end of 80s integrated circuit protection,substitutes for the transistor protection gradually. The development, the production, the application the integrated circuit protects which to the beginning of the 90s still were in the dominant position, this was the integrated circuit protection time. The integra
