電氣機器의 過負荷特性에 關한 理論的 考察 = Theoretical Study on the Characteristics of Electrical Machinery and Apparatus

다국어 초록 (Multilingual Abstract)

In electrical machinery and apparatus, the most important problem is protect of machinery and apparatus in duo to transient phenomena and overload on operation.
Particularly by advanced technology of late, there is demand for low cost of equipments and high percentgae of use of equipments. Therefore, protection of machinery and apparatus in condition of overload is more valued considering that all efficiency increase is passued by oper-ating all machinery and apparatus in condition of heavyload. In this paper, with induction motor as central figure, studies theoretically calculation of allowance values of voltage variat-ion, temperature increase, overload operation, etc, providing that local temperature increase value accompanied in electrical machinery and apparatus can be controlled below the mean value of temperature in crease. the author garspsthat electrical machine can be used in condition of overload value by caculation.
