DEGRADATION DETERMINATION SYSTEM OF POWER TRANSMISSION LINE ATTACHMENT AND DETERIORATION DETERMINATION METHOD OF THE POWER TRANSMISSION LINE ATTACHMENT

To provide a degradation determination system of a power transmission line attachment, capable of simply and quickly performing processing for determining deterioration of an attachment adhered to an overhead power transmission line in low cost.SOLUTION: A degradation determination system 1 of a power transmission line attachment, attached to an overhead power transmission line 50, and determining a deterioration level of an attachment 10 in which a conductive current flowing in the power transmission line 50 flows, comprises: a flight vehicle 2; and a determination device 3. The flight vehicle 2 photographs the attachment 10 with a thermography 20 by flying until a vicinity position of the attachment 10, and determines a value Ic of the conductive current flowing in the overhead power transmission line 50 with a current measurement device 21, and transmits data D of an image obtained to the determination device 3 by photographing and the value Ic of the conductive current, measured. The determination device 3 calculates a current value I corresponded to a temperature T of the attachment 10 obtained on the basis of the data D of the image, and determines the deterioration level of the attachment 10 on the basis of the current value I calculated and the value Ic of the conductive current.SELECTED DRAWING: Figure 1 【課題】架空送電線に取り付けられた付属品の劣化を判定する処理を、簡便に安価にかつ迅速に行うことが可能な送電線付属品の劣化判定システムを提供する。【解決手段】架空送電線５０に取り付けられ、架空送電線５０を流れる通電電流が流れる付属品１０の劣化度合いを判定する送電線付属品の劣化判定システム１は、飛行体２と、判定装置３とを備え、飛行体２は、付属品１０の近傍の位置まで飛行してサーモグラフィ２０で付属品１０を撮影するとともに、電流測定装置２１で架空送電線５０を流れている通電電流の値Ｉｃを測定し、撮影した画像のデータＤと測定した通電電流の値Ｉｃを判定装置３に送信し、判定装置３は、画像のデータＤに基づいて割り出した当該付属品１０の温度Ｔに相当する電流値Ｉを算出し、算出した電流値Ｉと通電電流の値Ｉｃに基づいて、当該付属品１０の劣化度合いを判定する。【選択図】図１
