摘要
高压及特高压远距离架空输电线路覆冰给电力安全带来挑战。为克服传统检测方法在远距离、实时监测和准确性方面的局限,设计了基于电容效应的覆冰检测电路,采用弧形极板电容传感器,以非接触式测量方式确定其电容与覆冰厚度关系。通过硬件电路实测与Multisim软件仿真对比验证,结果表明该电路操作便捷,稳定性和抗干扰能力强,测量精度高,为电力输电安全监测提供有效方案。
The icing of high-voltage and extra-high voltage long-distance overhead transmission lines poses challenges to power safety.To overcome the limitations of traditional detection methods in terms of long-distance monitoring,real-time monitoring,and accuracy,an icing detection circuit based on the capacitance effect was designed.An arc-shaped plate capacitive sensor was adopted,and a non-contact measurement method was used to determine the relationship between its capacitance value and the icing thickness.Through the comparative verification of the measured results of the hardware circuit and the Multisim simulations,the results show that this circuit is easy to operate,has strong stability and anti-interference ability,and high measurement accuracy,providing an effective solution for the safety monitoring of power transmission.
