Abstract

본 논문에서는 고주파 용접기의 가변 리엑터 및 커패시터를 해석하여 최적화 설계 하였다. 고주파 용접기의 극판 부분은 콘덴서의 역할을 하기 때문에 큰 정전 용량의 콘덴서를 만들기 위해서는 유전율이 큰 재료의 선택과 극판의 면적을 크게 하고, 극판의 간격을 얇게 하여야 한다. 하지만 많은 전류가 흐르기 때문에 저항이 발생하여 열이 발생하게 된다. 이러한 극판의 열 변형을 막기 위하여 냉각수 등을 이용한 방법으로 극판의 열을 식힌다. 이때 극판의 변형 및 온도에 따른 냉각수의 속도를 최적화 하였다. In this paper, variable reactor and capacitor for high-frequency welder are analyzed by optimum design. As the polar panel of high-frequency welder has the role of condenser, the material with the high rate of induced electricity has to be selected in order to manufacture the condenser with the great power cut. And the area of polar panel must be large and the gap between panels must be thin. On the contrary, the resistance is generated and the heat is happened because the large current is flown. To prevent the thermal deformation of this polar panel, the temperature can be lowered by using cooling water and so on. At this point, the speed of cooling water due to deformation and temperature of polar panel can be optimized.
