초록

전자유도 가열시설에서 정밀하고 일정한 주파수 성분에 의해 가열물체에 발열을 유도하려면 LC공진회로 설계단계에서 출력 주파수에 대한 커패시터의 정전용량(C)과 워크코일의 유도계수(L) 설정이 중요하다. 하지만 고유의 발열계수를 가진 물체의 가열위치와 범위에 직접유도를 하는 워크코일은 고정적으로 설계되는 반면 커패시터는 가변되도록 설계되어야만 전체장비의 활용도가 높아진다. 본 논문에서는 $1000V_{MAX}$ 최대전압과 $200I_{MAX}$ 전류에서 최대 700kHz의 고주파 LC공진 출력이 되도록 커패시터 내부구성 원자재 선정 및 공정설계 단계까지 단일전극 용량별 샘플을 추출하였다. 그리고 정전용량 규격변화에 따라 주파수 변화특성과 출력 파라메타 결과를 바탕으로 HF-LC공진용 전도냉각 커패시터의 최적설계를 위한 관계를 증명하는 기초 실험결과를 제시하였다.

It is important to configure capacitance(C) of the capacitor and the induction coefficient(L) of the work coil on the resonant circuit design stage in order to induce heating on the object by a precise and constant frequency components in the electromagnetic induction heating equipment. Work coil conducts a direct induction heating according to heating point and area of the object which has a fixed heat factor so that work coil is designed to has fixed value. On the other hands, Capacitor should be designed to be changed in order to be the higher the utilization of the entire equipment. It is extracted the samples by variation of single electrode capacity from the selection stage of raw materials for capacity to the stage of process design for output of the high frequency LC resonance of 700kHz on 1000 VAC maximum voltage and current to $200I_{MAX}$. It is suggested fundamental experiment results in order to prove relation for the optimal design of HF-LC resonance conduction-cooled capacitor based on the response of frequency characteristics and results of output parameters according to variation of the capacitance size.
