Research Of Key Technology Of The New Type Economy Transformer With Triangle Configuration Round Section Roll-core

The "Research of key technology of the new type economy transformer with triangle configuration round section Roll-core" is an important project of shanghai science and technology committee.The new type economy transformer with symmetrical triangle configuration round section Roll-core that was designed recently, its Roll-core designing and manufacture technology need some more research and development.The manufacture technology of new type economy transformer with symmetrical triangle configuration round section Roll-core consists of designing, cutting, coiling, anneal, looping, assembling and check out. This paper aims at technical difficulty of designing , cutting and coiling of triangle configuration round section Roll-core mostly, researching this key technology.Research of the control system and cutting means of cutting unwrapped metal band, firstly, this author put forward saving stuff scheme Resigning the cutting means , programming the CAD software and design the control system of cutting.Research of the coiling technology, Firstly, the author founded the math model of tension form. Basing on model, the author put forward the double closed loop control scheme. Secondly, this paper put forward the mend Generalized Predictive Control basing on BP network, the application of GPC on BP network to the tension control indicate the control effect is very good.Research of rectifying deviation of coiling technology, Firstly, the author brought forward the technology of photoelectric detector automatic follow center to solve the running deviation of "changing center" coiling. Secondly, the author designing new type Three-roller rectifying deviation equipment. It is designed with the technology of grading pressure and delay control. Finally, the paper brought forward a controller that based on fuzzy- immunity PID andgrads error algorithm, the application of this controller to the rectifying deviation control indicate the control effect is better than immunity PID controller.Research of the expert system of diagnosing malfunction of manufacture, Firstly, adopting the knowledge expression of basing on "module+cell+rule", the author designed the repository of the expert system of diagnosing malfunction of manufacture. Secondly, the paper brought forward the illation mechanism of basing on "sense idea", but it has a flaw, so the author brought forward the illation mechanism of basing on fuzzy math and saving overlay gather theory. Finally, the author programmed software of the expert system of diagnosing malfunction of manufacture basing on web.Research of the saving energy principle of" the symmetrical triangle structure round section Roll-core transformer, This paper aims at the symmetrical triangle structure round section Roll-core transformer with three-phase transmit electricity and power distribution, It mainly analyzed ^ reasoned and calculated the aspects of magnetic circuit (analyzing of magnetic circuit ^ harmonic wave of high times), empty-carry loss (hysteresis loss^ eddy current loss), and empty-carry current etc, which proves that this transformer is a kind of "energy-saving" transformer.
