Abstract:
A resin impregnation detection device configured to detect resin impregnation in a resin impregnation process for a coil insulation layer. The resin impregnation detection device can be inserted in a narrow portion, is capable of detecting impregnation with a liquid resin, and does not leave metal foreign materials other than an optical fiber in a product even after the resin impregnation. The resin impregnation detection device includes an optical fiber including an FBG sensor, and a coating resin, which coats the FBG sensor. The coating resin includes a resin to be softened by contact with a detection target resin. The FBG sensor is applied with a compressive strain caused by cure shrinkage of the coating resin or heat shrinkage thereof from a curing temperature to a normal temperature.

Claim (Index 1):
A resin impregnation detection device, comprising:\n an optical fiber including at least one FBG sensor; and a coating resin, which is coated by applying a compressive strain to the FBG sensor when being cured, wherein the coating resin includes a resin to be softened by contact with a detection target resin, and wherein the resin impregnation detection device is configured to detect impregnation with the resin by the FBG sensor, which is configured to detect, when the compressive strain applied to the FBG sensor is released during the softening, a change in a Bragg wavelength caused by the release of the compressive strain.
