摘要： An arrangement and a method for the gradual shutoff of potential in high voltage technology. The arrangement has at least one armature body, an electrically insulating film, and electrically conductive regions. The electrically conductive regions are arranged between layers of the electrically insulating films, and at least parts of the electrically insulating film are arranged around the at least one armature body. The arrangement is used in direct current applications. Resistive compensation currents are reduced and/or avoided along the electrically insulating film, and/or by an armature body, which functions as a first gradual potential shutoff coating, and/or by way of the electrical contacting of the outermost electrically conductive region between layers of electrically insulating film via an electrical contact through an opening in the outer layer of the insulating film.

摘要： A coil component that includes a core, a first wire, and a second wire. The core has a prism-shaped winding core part. The first wire and the second wire are wound around the winding core part. The coil component has an overlapping winding region in which the first wire is wound around the winding core part and the second wire is wound around the winding core part on top of the first wire. The overlapping winding region includes a prescribed part in which the first wire and the second wire are wound around the winding core part in such a manner that a gap is interposed between a part of the first wire that is wound along a first side surface of the winding core part and a part of the second wire that is wound along the first side surface.

摘要： An inductor and method for making the same are provided. The inductor includes a coil that is not wound around itself. The coil may have an “S”-shape. The coil has two leads extending from opposite ends of the coil. An inductor body surrounds the coil and portions of the leads. The leads may be wrapped around the body to create surface mount leads on the exterior of the inductor.

摘要： The invention relates to a surge detector comprising a transformer comprising a primary winding arranged to receive a fraction of a surge current and a secondary winding magnetically coupled to the primary winding and arranged to output a signal representing the fraction of the surge current. The surge detector further comprises a shunt connection in parallel with the primary winding, wherein the impedance of the shunt connection is lower than the impedance of the primary winding.

摘要： A coil component includes an insulating base body and a coil conductor arranged in the base body and having a winding portion extending around a coil axis. The insulating base body includes a magnetic body portion made of a magnetic material and a magnetic gap portion made of a low-permeability material having a lower relative permeability than the magnetic material. The magnetic gap portion is shaped like a ring when seen in a direction along the coil axis and arranged within the winding portion. The magnetic body portion includes a first region positioned within the winding portion, a second region positioned opposite the first region with respect to the magnetic gap portion in the direction along the coil axis, and a third region arranged within a through hole defined by an inner peripheral surface of the magnetic gap portion, where the third region connects together the first and second regions.

摘要： A laminate of a laminated coil includes first and second sections in a stacking direction from a first surface toward a second surface. The number of windings of each of coil conductor patterns on insulation resin layers, respectively, in the first region is equal to or more than the number of windings of a coil conductor pattern on an insulation resin layer in the second section, and is more than the number of windings of the coil conductor pattern closest to the second surface in the second section. The number of main conductor portions per unit distance in the first section is more than the number of main conductor portions per unit distance in the second section. The outermost main conductor portion of the coil conductor pattern in the second section has a width more than a width of the main conductor portion of the coil conductor pattern in the first section.

摘要： A device includes a core structure including a first end plate and a second end plate. The first end plate and second end plate include a first portion and a second portion that extend from opposing sides of a third portion and include an increasing cross-sectional area configured to provide soft saturation properties in response to increasing electrical current. The core structure may further include a coil member and a core section. The core section is disposed between the first plate member and second plate member. The core section includes a first core member, a second core member, and a central disc member. The core section also includes a channel formed between the central disc member and the first core member and the second core member to enable the coil member to circumferentially wind around the central disc member.
