Abstract

The invention discloses a high-precision wireless cable partial discharge detector. The detector comprises a signal acquisition module, a control module and a wireless communication module, wherein a signal output end of the signal acquisition module is connected with a signal input end of the control module, a data port of the control module is connected with a data port of the wireless communication module, the signal acquisition module comprises multiple high-frequency sensors, multiple program control amplifiers, multiple anti-aliasing filters and multiple A/D converters, and a control signal output end of the control module is connected with a control signal input end of each program control amplifier. According to the invention, a multi-channel data synchronization module composed of the high-frequency sensors, the program control amplifiers, the anti-aliasing filters and the A/D converters is adopted to enable the detector to have high detection precision, high detection speed and reliability; and meanwhile, the wireless communication module is adopted to enable the detector to have a wireless data transmission function.

Description

technical field [0001] The invention relates to a partial cable detector, in particular to a high-precision cable partial discharge wireless detector. Background technique [0002] Cable partial discharge is the main cause of insulation aging, and it is also an important symptom and manifestation of insulation degradation. It is closely related to the degradation and breakdown process of insulation materials, and can effectively reflect the fault of DC cable insulation. Partial discharge is an important index to evaluate the cable insulation condition. At present, the cable partial discharge detectors developed by some domestic companies are technically controlled by single-chip microcomputers or bus industrial controllers, but the detection accuracy is not high, the detection speed is low, the volume is large, the operation is complicated, the reliability is poor, and wireless data cannot be realized. transmission. Contents of the invention [0003] The purpose of the p...
