    • An interrupter circuit is disclosed for interrupting power in a power cable from a power source. The power cable comprises an insulated first wire and an insulated second wire with a conductive shield surrounding the first wire and the second wire. A non-insulated drain wire contacts the conductive shield. An outer insulating layer is molded about the conductive shield. A disconnect switch is interposed between the power source and the power cable with a disconnect switch driver controlling the disconnect switch. A sensing circuit is connected between the drain wire and the disconnect switch driver for sensing a leakage current between the conductive shield and one of the insulated first wire and the insulated second wire for opening the disconnect switch for disconnecting the power cable from the power source.
    • 公开了一种用于从电源中断电力电缆中的电力的断续电路。 电力电缆包括绝缘的第一线和绝缘的第二线,其中围绕第一线和第二线的导电屏蔽。 非绝缘漏极导线与导电屏蔽接触。 围绕导电屏蔽件模制外绝缘层。 断开开关由电源和电源电缆之间插入,断开开关驱动器控制断开开关。 感测电路连接在漏极线和断开开关驱动器之间,用于感测导电屏蔽与绝缘第一线和绝缘第二线之一之间的漏电流,用于打开断开开关以断开电源线与电源的连接。
