新型馈电状态传感器的研究

The Researching of New Type Feedback Electricity State Transducer

文章根据《矿井安全监控新标准、新规程汇编》[1],首次研制了一种新型馈电状态传感器,这种传感器是以电容检测原理来监测电缆芯线对地电场状态的传感器,从而间接检测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。这种馈电状态传感器具有结构简单、成本低、可靠性高、灵敏度高、易于维护、更换方便等优点。

This paper has developed a first new type feedback electricity transducer, whose working principle is the capacitance inspection principle, 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. This kink 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 output the state of feedback electricity or else the none state of feedback electricity. This transducer is in accordance with The Compilation of New Standards and New Regulations in Mine Security Monitoring. Its advantages are simple-structure, low-cost, high-reliability, high-sensitivity, easy-maintenance, convenient-replacing, etc.
