To provide an electric wire protection device with low possibility of melting of a melting element, and an electric wire protection method and a computer program.SOLUTION: In a power supply control apparatus 10 functioning as an electric wire protection device, a melting element F1 is arranged in a current path of current flowing via an electric wire W1. The melting element F1 is melted in accordance with a temperature of the melting element F1. A switching circuit G1 has an FET. The FET is arranged in the current path of the current flowing via the electric wire W1. If a microcomputer 20 determines that the temperature of the electric wire W1 is equal to or higher than a threshold value of the temperature, the FET is turned off.SELECTED DRAWING: Figure 1

    【課題】溶断素子が溶断される可能性が低い電線保護装置、電線保護方法及びコンピュータプログラムを提供する。【解決手段】電線保護装置として機能する給電制御装置10では、電線W1を介して流れる電流の電流経路に溶断素子F1が配置されている。溶断素子F1は、溶断素子F1の温度に応じて溶断される。スイッチ回路G1はFETを有する。電線W1を介して流れる電流の電流経路にはFETが配置されている。マイコン20が電線W1の電線温度が温度閾値以上であると判定した場合、FETはオフに切替えられる。【選択図】図1
