Abstract

The invention discloses a verification apparatus, method and device of a UHF (ultra-high-frequency) partial discharge live detection device. The verification apparatus comprises a pulse generator for transmitting calibration signals, a UHF reception sensor for collecting the calibration signals, and a UHF detector main machine which is connected with the UHF reception sensor and is used for detecting impulse response signals; and the comparison result of the impulse signals and the calibration signals is used for indicating the test performance of the UHF partial discharge live detection device. With the verification apparatus, method and device of the invention adopted, the technical problem that field verification cannot be performed on the UHF partial discharge live detection device in the prior art can be 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 UHF partial discharge charging detection device. Background technique [0002] At present, GIS partial discharge UHF detection technology has not been popularized and applied in my country for a long time, and domestic research on on-site verification technology is still in its infancy. The existing CIGRE verification method has the following problems: [0003] 1) There is no built-in UHF sensor on the running GIS equipment, and it is impossible to inject verification signals into the GIS. [0004] In the verification method recommended by GIGRE, two built-in UHF sensors need to be installed on the GIS equipment. As far as the country is concerned, GIS equipment has been widely used since the 1980s, and UHF detection technology began at the beginning of this century. At present, the built-in UHF sensor is not installed on the vast maj...
