The invention discloses AE local discharge live detection device checking equipment, method and device. The checking equipment comprises a pulse generator, a coupling device and an ultrasonic detector host, wherein the pulse generator is used for transmitting calibration signals, and the coupling device is connected with a checking platform through a coaxial RF (radio frequency) cable. A detected ultrasonic sensor is attached to a preset position of the checking platform, the ultrasonic detector host is used for detecting pulse response signals, and comparison results of pulse signals and the calibration signals are used for indicating the testing performance of an AE local discharge live detection device. The checking equipment solves the technical problem that the AE local discharge live detection device cannot be checked on site in related technology.
Description
technical field [0001] The present invention relates to the field of electric power, in particular to a calibration device, method and device for an AE partial discharge charging detection device. Background technique [0002] Research shows that there is no scientific and effective on-site method for AE partial discharge detection devices. Generally, a lighter is used to simply ignite near the RFCT, and the system responds. It can only be found that the system has serious performance degradation or damage, but cannot Effectively find a slight decline in system performance or perform quantitative evaluation. [0003] Aiming at the problem that related technologies cannot perform on-site verification of the AE 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, method and device for an AE partial discharge electrification detection dev...
