factory the advanced making the technique after the electric appliances, establishing the our country own after electric appliances manufacturing industry.As a result in 60's the our country have set up after electricity protection 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 50's, the transistor protects after the electricity already at start studying.In 60's to is a transistor to protect the booming development after the electricity in 80's 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 protection 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 70's inside, according to gather carry the integrated circuit that calculate the enlarger the protection have started studying.Have become the complete series to the 80's end integrated circuit protection, replace the transistor protection gradually.Research to manufacture, produce protectively to the beginning of 90's 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 direction 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 several 220 kVses with a circuit.
The our country have started the calculator namely from the end of 70's 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 electric power college, the transportation university of Xian, University of Tienjin, the transportation university of Shanghai, heavy celebrate the tiny machine protection of different from the Nanking electric power automated the institute for research to all research to manufacture one after another principle, different pattern in university equip.The 1984 is original north China the tiny machine in road in power line protection device that electric power college research to manufacture first passes to authenticate, and acquire in system the application, uncovering our country after electricity protection development history top new a page, developped the road for the protective expansion in tiny machine.In main equipments protect aspect, southeast university with the generator that science and engineering university research to manufacture loses protection, generator protection with generator transformer set protect

too one after another in 1989, pass to authenticate in 1994, devotion circulate.The Nanking electric power automates the tiny machine circuit that institute for research research to manufacture the protection equips to also pass to authenticate in 1991.The University of Tienjin cooperates with Nanking electric power automation equipments factory the tiny machine that research to manufacture mutually the electric voltage compensate the high in direction in type protects, the transportation university of Xian cooperate with allow the after the electric appliances factory the positive preface that research to manufacture breaks down the high in direction in weight the protection too one after another in 1993, pass to authenticate in 1996.To this, the tiny machine circuit of the different principle, different model protects with the main equipments each special features, provided a batch of new generations function for the electric power system good, the function is well-found, work dependable after electricity protection equip.Protect the research of the device along with the tiny machine, also obtained a lot of theorieses result in the aspects of tiny machine protection software, calculate way...etc..Can say that protect the technique to have entered the protective ages in tiny machine after the electricity from the 90's beginning our country.
Protecting after the electricity future trend in technique is to turns to calculator, the network turn, the intelligence turn, protect, control, measuring to correspond by letter with the data the integral whole turn the development.

The electric power system increases continuously to the protective request in tiny machine, in addition to protective and basic function, should still have the big capacity break down the information to deposit the space with data over a long period of time, the fast data handles function, mighty correspondence ability, protect, control with other to equip with adjust an ability for the net to share whole system data, information with network resources, high class language plait distance etc..This will beg the tiny machine protection equips the function that have an equal to set PC machine.Protect the development in the calculator early, onced conceived to use a the small scaled calculator in set makes after electricity protection equip.Because the at that time small scaled machine physical volume is big, the cost is high, the dependable is bad, it is not realistic that this conceive.Now, the together tiny machine protection equiped the function, speed, saving capacity that the work of the size likeness control machine to exceed the small scaled machine of that year consumedly, therefore, use a work controls the machine makes after electricity the protective opportune moment is already mature, this will be an one of the protective development in tiny machine directions. Turn after the tiny machine that protection equip of electricity, it is the development trend that can't converse that calculator turn.But to how to satisfy betterly the electric power system request, how further increase after electricity protective and dependable, how to obtain the larger economic performance with social performance, must proceed still concrete thorough of research.

The calculator network is used as the information to correspond by letter the technique a pillar that tool have become information ages with data, making mankind producing to take place with the feature that society life basic variety.It is deep to affect the each industry realm, also providing the powerful correspondence means for the each industry realm.So far, in addition to differing to move the protection to protect with the,all after electricity protection equip all an amount of electricity for can responding protection installing place.After the protective function in electricity too is limited by the excision breaks down a piece, contract trouble influence scope.This primarily is because of lacking the powerful data the
correspondence the means.The abroad puts forward the concept that system protect already, a peaceful and full-automatic device.Because after give or get an electric shock the protective function not is limited by excision break down a piece with limit trouble influence scope, still guarantee the whole system safe stability circulate.This will beg each protection unit can share the movement of the whole system with the data that breakdown information, each protection unit with heavy match the equip to moderate the action in analyzing these informationses with the foundation of the data, the safe stability that insure the system movement.Obviously, realize the protective and basic term in this kind of system is to connect with the calculator network the protection device of whole system each main equipments, that is realize the network that tiny machine protect device turn.This is under the current technique term complete possible.
