To provide an inspection device and an inspection method for trolley wire equipment by which defects and melting damage of trolley wire equipment can be detected in advance, adjustment of determination conditions and comparison confirmation to a real thing are not required for each equipment.SOLUTION: An inspection device 20 for trolley wire equipment, which inspects existence or absence of abnormality in trolley wire equipment that supplies electric power to a mover via a trolley wire, has: a thermal video imaging device 21 which is attached to and moves together with the mover, and images the trolley wire equipment as a thermal video; and a thermal determination part 22 which extracts temperature data at each position from the thermal video imaged by the thermal video imaging device, performs threshold value determination for the extracted temperature data, and determines whether temperature at each position is normal or abnormal.SELECTED DRAWING: Figure 2

    【課題】トロリ線設備の欠損や溶損を未然に検知することができ、設備ごとに判定条件の調整が必要なく、かつ実物との比較確認が不要なトロリ線設備の検査装置および検査方法を提供する。【解決手段】トロリ線を介して移動機に電力を供給するトロリ線設備の異常の有無を検査するトロリ線設備の検査装置20は、移動機に取り付けられ、移動機とともに移動して前記トロリ線設備を熱動画として撮像する熱動画撮像装置21と、熱動画撮像装置で撮像した熱動画から各位置における温度データを抽出し、抽出された温度データに対し、閾値判定を行い、各位置の温度データが正常か異常かを判定する熱判定部22とを有する。【選択図】図2
