Abstract

The invention discloses verifying equipment, method and device of a high-frequency-current partial discharge live detection device. The verifying equipment comprises a pulse generator, a coupling device and an HF detector mainframe, wherein the pulse generator is used for transmitting a calibration signal; the coupling device is connected with the pulse generator and is the variation form of a coaxial RF cable, and a to-be-tested RFCT sleeves the core wire of the coupling device; the HF detector mainframe is used for detecting a pulse response signal, and the comparison result of the pulse signal and the calibration signal is used for indicating the testing performance of the high-frequency-current partial discharge live detection device. By the verifying equipment, the technical problem that field verification cannot be performed on the high-frequency-current partial discharge live detection device in the prior art is solved.

Description

technical field [0001] The invention relates to the field of electric power, in particular, to a calibration device, method and device for a high-frequency current partial discharge charging detection device. Background technique [0002] The survey shows that there is no scientific and effective on-site method for high-frequency current partial discharge detection devices. Generally, a lighter is used to simply ignite near the RFCT, and the system responds. Only serious performance degradation or damage of the system can be found. However, it is impossible to effectively discover a slight decline in system performance or perform quantitative evaluation. [0003] Aiming at the problem that the relevant technology cannot perform on-site verification of the high-frequency current partial discharge live detection device, no effective solution has been proposed so far. Contents of the invention [0004] Embodiments of the present invention provide a verification device, metho...
