Abstract
Official abstract text for this publication.
A reactor that can measure the temperature of the magnetic core is provided. The reactor includes an assembly having a magnetic core and a coil that has a winding portion, and a temperature sensor that measures the temperature of the reactor. The magnetic core has an inner core portion that is inserted into the winding portion, and a sensor disposition groove is formed in an outer peripheral face of the inner core portion and is disposed inside the winding portion. The temperature sensor is provided inside the sensor disposition groove. According to this configuration, it is possible to precisely measure the temperature of the magnetic core while the reactor is operating.
First claim
Opening claim text (preview).
The invention claimed is: 1. A reactor comprising: an assembly having a magnetic core and a coil that has a winding portion bounding an opening; and a temperature sensor that measures the temperature of the reactor, wherein the magnetic core has an inner core portion that is inserted into the opening of winding portion, and a sensor disposition groove is formed in an outer peripheral face of the inner core portion and is disposed inside the opening of the winding portion, the inner core portion is constituted by a composite material that includes a soft magnetic powder and a resin, and the temperature sensor is provided in the sensor disposition groove. 2. The reactor according to claim 1 , wherein the sensor disposition groove extends toward a central side in an axial direction of the winding portion. 3. The reactor according to claim 1 , wherein the sensor disposition groove is formed in, among outer peripheral faces of the inner core portion, a face that is most distant from an installation target on which the assembly is to be installed. 4. The reactor according claim 1 , comprising an adhesive sheet that is disposed between an inner peripheral face of the winding portion and the outer peripheral face of the inner core portion in which the sensor disposition groove is formed, covers the temperature sensor provided in the sensor disposition groove, and adheres together the inner core portion and the winding portion. 5. The reactor according to claim 2 , wherein the sensor disposition groove is formed in, among outer peripheral faces of the inner core portion, a face that is most distant from an installation target on which the assembly is to be installed. 6. The reactor according claim 2 , comprising an adhesive sheet that is disposed between an inner peripheral face of the winding portion and the outer peripheral face of the inner core portion in which the sensor disposition groove is formed, covers the temperature sensor provided in the sensor disposition groove, and adheres together the inner core portion and the winding portion. 7. The reactor according claim 3 , comprising an adhesive sheet that is disposed between an inner peripheral face of the winding portion and the outer peripheral face of the inner core portion in which the sensor disposition groove is formed, covers the temperature sensor provided in the sensor disposition groove, and adheres together the inner core portion and the winding portion.
