PROBLEM TO BE SOLVED: To detect abnormality of a pantograph easily.SOLUTION: A pantograph abnormality detection system 1 comprises a light-receiving device 3 and a determination part 4. The light-receiving device 3 is provided so that a specific portion 5 in a collector shoe 21 of a pantograph 2 is included in a light-receiving range 31. An output of the light-receiving device 3 is input to the determination part 4. The specific portion 5 is a portion which becomes high temperature when an abnormality occurs to the collector shoe 21. The light-receiving device 3 has high spectral sensitivity to light of a specific wavelength region, which is emitted in accordance with a chemical or physical phenomenon occurring when the specific portion 5 is in a high temperature state. The determination part 4 determines that an abnormality has occurred to the pantograph 2 when the intensity of the light in the specific wavelength region received by the light-receiving device 3 is equal to or greater than a predetermined threshold value. This allows detection of the abnormality of the pantograph 2, in which the specific portion 5 becomes higher temperature as more light is emitted.SELECTED DRAWING: Figure 1

    【課題】パンタグラフの異常を容易に検知する。【解決手段】パンタグラフ異常検知システム1は、受光装置3と、判定部4とを備える。受光装置3は、パンタグラフ2の集電舟21における特定部分5が受光範囲31に含まれるように設けられる。判定部4は、受光装置3の出力が入力される。特定部分5は、集電舟21に異常が生じたときに高温状態となる部分である。受光装置3は、特定部分5が高温状態となったときに生じる化学的又は物理的な現象に伴って出射される特定波長域の光に対して高い分光感度を有する。判定部4は、受光装置3が受光した特定波長域の光の強度が所定の閾値以上であるとき、パンタグラフ2に異常が発生したと判定する。これにより、光が出射されるほどに特定部分5が高温状態となるようなパンタグラフ2の異常が検知される。【選択図】図1
