The 50s, our country engineers and technicians creat
6、ively absorption, the 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
7、to the national relay 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,
8、the design, the manufacture, 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 pro
9、tection was starting 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 transisto
10、r high frequency block 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
11、integration operational 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 t
12、he beginning of the 90s still were in the dominant position, this was the integrated circuit protection time. The integrated electricity road work frequency conversion quantity direction develops which in this aspect Nanjing electric power automation research institute high frequency protected the v
