Abstract
The traditional high-voltage cable shielding layer voltage monitoring method adopts the phase comparison method, which is easy to be interfered by external electrostatic induction, magnetostatic induction and other factors, resulting in low monitoring accuracy and efficiency. In view of the above problems, this paper studies the high-voltage cable shielding layer voltage monitoring method considering coil magnetic flux. After calculating the transfer impedance of cable shielding layer, the calculation model of high voltage cable magnetic flux mutual inductance parameters is constructed. The parameters such as induced voltage of cable shielding layer are determined, and the collected voltage signal is processed by morphology. Using Duffing chaos detection principle, the shielding layer voltage monitoring results are obtained. The experimental results show that the proposed method has high monitoring efficiency, and the minimum effective monitoring rate is 94.3%.
