摘要
As an ultra-precision electromechanical product, the precision of an inertial platform's electromagnetic components directly determines its performance. To address the challenge of detecting micro-defects within inertial components, this paper investigates a detection technology based on pulsed voltage partial discharge (PD). The designed detection method achieves a sensitivity of 1 pC, accurately capturing the weak discharge signals caused by micro-defects. The system supports outputting pulsed voltages up to 5 kV peak-to-peak, simulating various component operating electric field environments. To verify the feasibility of the method, a non-PD ceramic capacitor was first used to eliminate experimental interference and confirm detection reliability. Comparative PD tests were then conducted on defective and non-defective electromagnetic component specimens. Finally, the Weibull distribution was combined to effectively detect and identify micro-defects. The results demonstrate that this method can efficiently identify micro-defects in electromagnetic components, breaking through the limitations of traditional detection techniques. This method provides reliable technical support for quality control of inertial platforms and serves as a reference for micro-defect detection in similar ultra-precision electromechanical products.
