Characteristics of multifunctional melting unit designed for processing The metallic and oxide-containing charge materials have been considered.
Keywords: melting unit, energy characteristics, inductor.
- Application of variable frequency power supplies for improvement in efficiency and characteristics of induction heating of turbine disks at stand Kuvaldin, A. B.; Lepeshkin, A. R. (kuvaldinab@mpei.ru; lepeshkin@rto.ciam.ru), 25
The method of disk tests on the spin rig with use of power supplies
Of variable frequency is developed. The investigations into electric and power
Characteristics of the power supplies are carried out. Schemes of their
Connection to loading are offered. Actions for increase in efficiency and
Improvement in induction heating characteristics of turbine discs at
Thermocycle tests on the spin rig are introduced. The recommendations
For effective regulation of capacity of power supplies are given.
Keywords: variable frequency power supplies, induction heating, turbine Disks, electric characteristics.
Electric equipment repair and diagnostics
- Development of adaptive neural fuzzy system for applying the galvanic coating for repair of electric machines Petukhov, R. A.; Chegoshev, M. Yu. (chegoshevm@mail.ru), 30
Perspective method of reconditioning and strengthening the parts
Of electric machines and repair operation is applying the electrolytic
Coatings. Developed adaptive-fuzzy system makes it possible to optimize
Process of coating applying.
Keywords: galvanic coatings, electric machine repair, neural fuzzy
Systems.
Electric equipment safety
- Principle of operating of residual current devices Kharechko, Yu. V. (kharechko@mail.cnt.ru), 33
