摘要： A foreign matter detection device including a detection coil between a power transmitting coil and a power receiving coil, and a detection unit detecting an induced voltage V generated in the detection coil and detects, from this induced voltage, presence or absence of a conductive foreign matter between the power transmitting coil and the power receiving coil. The detection coil includes a continuous conductive wire where two loop portions are wound in mutually opposite directions. An area or a winding number of each loop portion or a direction connecting centroids of the two loop portions is set so that the induced voltage (i.e., a reference voltage) generated in the detection coil when no conductive foreign matters exist becomes 0 or a minimum.

摘要： A power transmission coil includes a plane coil including a no-wire portion and a coil wound about a no-wire portion, a cover for covering the plane coil from above, a first foreign-matter-detecting unit provided at the no-wire portion, and a power control circuit electrically connected to the plane coil and the first foreign-matter-detecting unit. An upper surface of the cover has a first inclining portion inclining toward the first foreign-matter-detecting unit. The power control circuit transmits power through the plane coil if a foreign matter is not detected in the no-wire portion based on an output from the first foreign-matter-detecting unit. The power control circuit is configured to stop transmitting power through the plane coil if foreign matter is detected in the no-wire portion based on an output from the first foreign-matter-detecting unit. This power transmission coil is capable of detecting a small foreign matter that may generate heat.

摘要： A coil housing has an inner ring, which is shaped into an annular form and is placed on an inner side of an electromagnetic coil in a radial direction of a rotational axis. A thermal fuse is placed on an inner side of a coil inner peripheral end of the electromagnetic coil in the radial direction, so that the thermal fuse can be placed in such a manner that the thermal fuse does not limit a length of the electromagnetic coil in a direction of the rotational axis by using a radial thickness of the inner ring that is indispensable as a part of a structure of a magnetic circuit. Thus, it is possible to sufficiently limit occurrence of limiting of a size of the electromagnetic coil that is caused by the placement of the thermal fuse.

摘要： The invention relates to a high voltage transformer (6) having a sensor system (30) for monitoring physical characteristic variables. In particular, said sensor system has at least one sensor (1) that comprises a glass fiber (3) with a sensor head (2). Said sensor head supports a plurality of Bragg gratings (7, 8, 9). An evaluation unit (10) is associated with the sensor system and is connected to the at least one sensor head via said glass fiber. The invention is based on the general inventive concept of arranging the sensors of the sensor system between successive windings (4, 5) of the high voltage transformer using spacers. In addition, the use of a plurality of Bragg gratings in the sensor head ensures that at least one of the Bragg gratings determines the actual physical characteristic variables such as temperature or contact force (A).

摘要： A reactor includes an annular core, coils, a sensor detecting a state of the reactor, and a connector outputting signal from the sensor. Resin-molded bodies are provided around the annular core. The resin-molded body has bobbins for the respective coils and core covering portions formed integrally with each other. An exposed area where no resin covers the bottom of the core is formed in the lower face of the covering portions. A holder to fasten the connector is formed integrally with the upper portion of the covering portion. An assembly including the resin-molded bodies in which the annular core is embedded, and the coils wound around the bobbins are retained in a metal casing. A clearance is formed between the assembly and the casing, and a filler is filled in this clearance. The filler covers the exposed area of the core bottom.
