1、附 录 The electric power system protects the technical present condition after the electricity and development The electric power system flies to develop soon to protect to put forward the new request continuously after the electricity, the electronics technique, calculator technique fly to develop so

2、on with correspondence technically again for protecting the technical development to infuse into the new vitality constantly after the electricity, therefore, protect the technique with abundant resources after the electricity, completed the stage in 4 histories of the development in 40 times of rem

3、aining years of lifes. After founding a nation, the our country protects the course after the electricity, after electricity protection design, after electric appliances manufacture industry with protect the technique troops after the electricity from have no to have, walked through the road that a

4、century of advanced countries half walk through in about 10 yearses.50s, our country engineering the technical personnel creates sex ground absorb, digest, controled the abroad the advanced protecting the equipments function with circulate the technique after the electricity, set up a has the deep p

5、rotecting the theories scholastic attainment with after the electricity empirical after give or get an electric shock and protect technique troops, to whole country after give or get an electric shock and protect the technique troops establishes with grows up to have the leading function.The city of

6、 ushered in the digest the at that time abroad after the electric appliances factory the advanced making the technique after the electric appliances, establishing the our country own after electric appliances manufacturing industry.As a result in 60s the our country have set up after electricity pro

7、tection research, design, make and circulate with the complete system of the teaching.This is the ages that machine electricity type prospers after the electricity protection, after the electricity for the our country From the end of 50s, the transistor protects after the electricity already at star

8、t studying.In 60s to is a transistor to protect the booming development after the electricity in 80s with the extensive and adoptive ages.Among them the University of Tienjin automates with Nanking electric power the equipments factory cooperates the investigative high irection in a transistor prote

9、ction to automate with the Nanking electric power the high in transistor that institute for research research to manufacture shuts to lock the distance protects, circulating on the Gezhouba, ends a circuit the protection is complete depend on ages imported from the abroad. Here period, from the 70s

10、inside, according to gather carry the integrated circuit that calculate the enlarger the protection have started studying.Have become the complete series to the 80s end integrated circuit protection, replace the transistor protection gradually.Research to manufacture, produce protectively to the beg

11、inning of 90s integrated circuit and apply to still be placed in the predominant position, this is the integrated circuit protection ages.The in this respect Nanking electric power automates the integrated circuit work variety that institute for research research to manufacture measures high in dire

12、ction the protection has the important function, the University of Tienjin automates with Nanking electric power the integrated circuit that equipments factory cooperate researches to manufacture mutually the electric voltage compensates the high in direction in type protection also circulates in se

13、veral 220 kVses with a circuit. The our country have started the calculator namely from the end of 70s after the protective research of electricity, high etc. college with section a function for rising first leading.inside science and engineering university, southeast university, north China electri
