A physical model of an induction electric heater for cryogenic control devices
- 28 Downloads
A physical model of an induction electric heater for cryogenic control devices has been proposed. The chosen method of research has been justified. The scheme of the model, the structure of the measuring equipment, and a research technique that determines the energy characteristics of the induction heater have been considered, and recommendations on its design have been made. It is shown that it is advisable to use a three-leg laminated core with the winding located in the middle core as a basic element. Such a structure of the induction heater allows one to carry out research varying the material and shapes of the heated object. A microprocessor measuring complex that allows one to control and record up to six electric signals with an error no higher than 2% has been proposed.
