摘要
为了进一步提高馈电状态传感器的性能,研制了一种新型馈电状态传感器,它根据电容检测原理,采用场效应管作为传感器的敏感元件,监测电缆芯线对地电场的状态,从而间接检测出矿井电缆的馈电状态与负载是否工作、电缆有无电流流过无关。只要电缆芯线带电,则输出馈电状态;反之,输出非馈电状态。
For the sake of more enhancing capabilities of feedback electricity transducer, developed a new type feedback electricity transducer,whose working principle is the capacitance inspection principle, adopting field effect transistor as sense organ of transducer, which supervising the states of electric field between the cable-line and the ground, so it can inspect the feedback electricity states of mine well cable-line. The kind of inspecting way is irrespective with load whether it is working or not and cable-line whether it has electrical current or not. If only when cable-line has electricity, then transducer export the state of feedback electricity or else the none-state of feedbak electricity.
