Installation structure for temperature sensor in electrical machinery and apparatus

摘要

In an electrical machinery and apparatus, a storage space is formed along an extension direction of a strand, and a temperature sensor is installed in the storage space of the strand, so that temperature of the strand can be immediately measured, and no pressure is applied to the temperature sensor in the process of forming a ground wall insulation thereby the temperature of the strand can be accurately measured.

主权项

1. An electrical machinery and apparatus comprising:
a rotor having an insulated bar, the insulated bar having strands assembled and a ground wall insulation formed on the outer periphery of the strands assembled, each of the strands being made up of a rectangular wire and having a strand insulation, a first wide-width surface facing the inside diameter side of the rotor, a second wide-width surface facing the outside diameter side of the rotor, and a storage space formed along an extension direction of the strand and being a groove formed on the first wide-width surface of the strand; and a temperature sensor that is stored in the storage space, wherein
the groove is formed by removing the strand insulation and the wire at a region on the side of the first wide-width surface of the strand, such that the temperature sensor directly contacts the wire, andthe strand insulation is formed on the outer periphery of the strands, except for a portion of the outer periphery of the strands at which the groove is formed.
