Abstract
A partial discharge (PD) detection apparatus for gas-insulated equipment includes a photon collector, an optical splitter, a first photoelectric conversion module, an ultraviolet fluorescent crystal, a second photoelectric conversion module, and a signal processing module, where the ultraviolet fluorescent crystal is configured to convert a second optical radiation signal into an optical radiation signal of an ultraviolet fluorescence band, and the signal processing module is configured to calculate first apparent intensity based on a first voltage signal output by the first photoelectric conversion module, calculate second apparent intensity based on a second voltage signal output by the second photoelectric conversion module, and determine discharge intensity of the optical radiation based on a ratio of the second apparent intensity to the first apparent intensity. Technical solutions of the present disclosure are not affected by an unknown distance between a discharge position and a detection point.
