A lightning arrester monitoring device is provided with: a galvanometer (21) for measuring the value of current flowing from a lightning arrester (16) to a vehicle body (19) of a railway vehicle in a circuit (18) between the lightning arrester (16) of the railway vehicle and the vehicle body (19) of the railway vehicle; a data memory (22) that records the current values measured by the galvanometer (21) as history data in time series; and a controller (23) which determines that the arrester (16) has deteriorated and outputs a prescribed deterioration signal if the average value of the current values in a prescribed unit time exceeds a prescribed deterioration threshold value on the basis of the time series change of the history data recorded in the data memory (22). As a result, the deterioration of the arrester (16) provided in the railway vehicle is monitored.

    一种避雷器监测装置,具备:检流计(21),在铁路车辆的避雷器(16)与铁路车辆的车身(19)之间的电路(18)中测量从避雷器(16)流向车身(19)的电流值;数据存储器(22),将检流计(21)测量的电流值按时间序列记录为履历数据;以及控制器(23),根据记录于数据存储器(22)的履历数据的时间序列变化,若在规定的单位时间内的电流值的平均值超过规定的劣化阈值,则判定避雷器(16)已劣化,输出规定的劣化信号。由此,监测配备于铁路车辆的避雷器(16)的劣化。
