摘要： Disclosed in the present disclosure are an anti-direct-current nanocrystalline double-magnetic-core current transformer magnetic core and a manufacturing method therefor. The anti-direct-current nanocrystalline double-magnetic-core current transformer magnetic core comprises a first nanocrystalline magnetic core, a second nanocrystalline magnetic core, and an annular packaging shell; and the first nanocrystalline magnetic core is sleeved at the outer side of the second nanocrystalline magnetic core, and the first nanocrystalline magnetic core and the second nanocrystalline magnetic core are coaxially arranged. The manufacturing method for the anti-direct-current nanocrystalline double-magnetic-core current transformer magnetic core comprises the following step: sequentially mounting the first nanocrystalline magnetic core and the second nanocrystalline magnetic core into the packaging shell to obtain the anti-direct-current nanocrystalline double-magnetic-core current transformer magnetic core. According to the anti-direct-current nanocrystalline double-magnetic-core current transformer magnetic core provided by the present application, two nanocrystalline magnetic cores are comprised in the anti-direct-current nanocrystalline double-magnetic-core current transformer magnetic core, and the magnetic cores are excellent in stability, good in linearity, high in sensitivity, and large in the adjustment range of magnetic conductivity. In addition, the manufacturing method provided by the present application is simple and low in processing cost.

摘要： Provided is a sheet-shaped magnetic member. The sheet-shaped magnetic member comprises magnetic ribbons with anisotropy, and includes a first group, a second group, and a third group. The third group is arranged so that a direction of anisotropy of the magnetic ribbons is along a direction different from both a direction of anisotropy of the first group and a direction of anisotropy of the second group. The first group, the second group, and the third group are arranged next to each other.

摘要： Es wird im Folgenden eine Vorrichtung beschrieben, die gemäß einem Ausführungsbeispiel einen Träger, der entlang einer Längsachse eine durchgehende Öffnung aufweist, sowie mindestens ein um den Träger zu einem Ringbandkern gewickeltes weichmagnetisches Band aufweist. Das Band ist dabei direkt auf den Träger gewickelt, sodass zwischen dem Ringbandkern und dem Träger kein Spiel vorhanden ist. Der Träger kann folglich als Teil des Gehäuses des Ringbandkerns dienen.
