Ultra High Voltage (UHV) reactors are critical core components in UHV power transmission projects, and their safe operation is directly related to the stability of UHV transmission lines. This study involves the collection of circumferential acoustic data from three operational 1000 kV UHV reactors (Phase A, Phase B, and Phase C, with acetylene levels elevated in Phase C) and utilizes near-ultrasonic PRPD acoustic analysis (frequency range 16 kHz–24 kHz, combining energy and phase information within this range) to identify that localized discharges near the magnetic shunt clamp of the reactor of Phase C reactor are the primary reason for the elevated acetylene levels in its oil chromatography. This validates the feasibility of using near-ultrasonic PRPD acoustic analysis for defect tracing in UHV reactors, providing a reference for the maintenance of UHV reactors.

摘要

Ultra High Voltage (UHV) reactors are critical core components in UHV power transmission projects, and their safe operation is directly related to the stability of UHV transmission lines. This study involves the collection of circumferential acoustic data from three operational 1000 kV UHV reactors (Phase A, Phase B, and Phase C, with acetylene levels elevated in Phase C) and utilizes near-ultrasonic PRPD acoustic analysis (frequency range 16 kHz–24 kHz, combining energy and phase information within this range) to identify that localized discharges near the magnetic shunt clamp of the reactor of Phase C reactor are the primary reason for the elevated acetylene levels in its oil chromatography. This validates the feasibility of using near-ultrasonic PRPD acoustic analysis for defect tracing in UHV reactors, providing a reference for the maintenance of UHV reactors.
