A monitoring device (308) of an open/closed state of an electrical line is disclosed. The device (308) comprises a first connection terminal (T1) and a second connection terminal (T2) connected to the electrical line, a current generator (301) providing a non-zero reference current (Ien) when there is a voltage greater than a predetermined minimum voltage Vmin across its ends, providing a zero current when there is a voltage less than the predetermined minimum voltage Vmin across its ends, at least one opto-isolator device (308, 605, 613), and at least one opto-isolator device (308, 605, 613), the opto-isolator device (308, 605, 613) being arranged between the first connection terminal (T1) and the second connection terminal (T2), and the opto-isolator device (308, 605, 613) being arranged between the first connection terminal and the second connection terminal. Comprising a lighting device (305, 603, 612) and respective photosensitive semiconductor elements (307, 604, 611), and a current detection and power supply module (304) that detects a current flowing therethrough, provides a power supply current to the lighting device (305, 603, 612) when the detected current is equal to or greater than a reference current (Ignen), and provides a zero power supply current to the lighting device (305, 603, 612) when the detected current is less than the reference current (Ignen). The photosensitive semiconductor element (307, 604, 611) assumes a first state when the lighting device (305, 603, 612) is off, the state indicating that the electrical circuit is open, and assumes a second state when the lighting device (305, 603, 612) is on. An electrical circuit is also described.

    公开了一种电气线路的开闭状态的监测装置(308)。该装置(308)包括连接到电气线路的第一连接端子(T1)和第二连接端子(T2),电流发生器(301),在其两端存在大于预定的最小电压Vmin的电压时提供非零参考电流(Igen),在其两端存在小于预定的最小电压Vmin的电压时提供零电流,至少一个光隔离器装置(308、605、613),包括照明装置(305、603、612)和各自的光敏半导体元件(307、604、611),以及检测流经其中的电流的电流检测和电源模块(304),当检测到的电流等于或大于参考电流(Igen)时,向照明装置(305、603、612)提供电源电流,当检测到的电流小于参考电流(Igen)时,向照明装置(305、603、612)提供零电源电流。光敏半导体元件(307、604、611)在照明装置(305、603、612)关闭时呈现第一状态,该状态指示电气线路处于断开,并在照明装置(305、603、612)开启时呈现第二状态。还描述了电气线路。
