摘要
针对新型无人直升机设计了一套外电源监测与控制系统,用于在外电源极性或电压指标合格时接通外电源接触器;反之,及时断开接触器,切断外部直流电源。在外电源供电时,系统可以有效地保护机上用电设备安全。实验表明该系统具有较高的精度和良好的稳定性。
A set of external power monitoring and control system is designed for the new unmanned helicopter,which is used to connect the external power contactor when the external power polarity or voltage index is qualified;contrarily,disconnect the contactor in time to cut off the external DC power.When powered by an external power,the system can effectively protect the safety of the electrical equipment on board.Experimental shows that the system has high accuracy and good stability.
