The invention provides a rapid evaluation device and method for an ultrahigh frequency partial discharge detection equipment host, and the device comprises a function signal generator, a signal cable, a waveform generator, a high-frequency signal cable, and a to-be-detected device, and the function signal generator is connected with the waveform generator through the signal cable. The waveform generator is connected with the equipment to be tested through a high-frequency signal cable, the function signal generator generates a trigger signal and transmits the trigger signal to the waveform generator through a signal cable, and the waveform generator generates various ultrahigh-frequency signals according to the trigger signal and transmits the ultrahigh-frequency signals to the equipment to be tested; capability evaluation is performed by the to-be-tested equipment according to the received ultrahigh-frequency signal to obtain an evaluation result, thereby solving the problem that the ultrahigh-frequency sensor and the host cannot be separated for independent evaluation.
Description
technical field [0001] The present application relates to the technical field of ultra-high frequency partial discharge monitoring, and in particular to a device and method for rapid evaluation of a host computer of ultra-high frequency partial discharge detection equipment. Background technique [0002] In recent years, insulation failures of electrical equipment represented by gas-insulated metal-enclosed switchgear (GIS), transformers, AC metal-enclosed switchgear and control equipment have occurred frequently, which has brought greater losses and risks to the power industry. The main form of electrical equipment insulation fault is partial discharge. The current UHF partial discharge detection equipment has been proved to be effective in detecting electrical equipment partial discharge. It is used in the field of partial discharge live detection and online monitoring of electrical equipment. [0003] However, there are many manufacturers of UHF partial discharge detecti...
