Abstract

본 발명은 전기·전자기기에 사용되는 리액터에 관하 것으로, 본 발명의 리액터는 하나 이상의 철심을 사용하여 형성된 □자형상의자로의 내측에 절연수단을 개재하여 배설된 주자각철심과, 주자각철심의 주위에 배설된 코일등으로 구성되어 있다.The present invention relates to a reactor used in an electric or electronic device. The reactor of the present invention comprises a core having a square shape and formed by using one or more iron cores, And a coil or the like disposed around the periphery.

이 구성에 의하여 주자각 철심은 다른 철심, 접지로부터 완전히 분리되므로, 코일과, 이에 관통하여 배설된 주자각철심과 사이의 전기절연이 불필요하게 되어 코일을 주자각철심에 직권할 수 있고, 코일의 전선사용량을 크게 저감할 수 있어 값싼 리액터를 얻을 수 있다.According to this configuration, since the iron core is completely separated from the other iron core and the ground, the electrical insulation between the coil and the iron core disposed through the core is unnecessary, so that the coil can be placed directly on the iron core. It is possible to greatly reduce the amount of wire used and obtain an inexpensive reactor.
