Abstract

The invention is suitable for the technical field of electric power, and provides an online detection and evaluation method and device for performance of built-in ultrahigh frequency sensors of a combined electric appliance, and the method comprises the steps: obtaining the distance between two adjacent ultrahigh frequency sensors and a GIS structure; according to the distance and the GIS structure, determining the distance between two adjacent ultrahigh frequency sensors and a signal attenuation coefficient estimation value generated by the GIS structure; inputting a preset standard signal to the GIS equipment through any one of the two adjacent ultrahigh-frequency sensors, and measuring a transfer function between the two adjacent ultrahigh-frequency sensors; and carrying out performance detection on the two adjacent ultrahigh frequency sensors based on the signal attenuation coefficient estimation value and the transfer function. According to the invention, performance detection can be conveniently and accurately carried out on the ultrahigh frequency sensor installed in the GIS equipment.

Description

technical field [0001] The invention belongs to the field of electric power technology, and in particular relates to a method and device for online detection and evaluation of the performance of a built-in UHF sensor in a combined electrical appliance. Background technique [0002] The UHF detection method is suitable for GIS partial discharge on-line detection. Many GIS insulation defects have been found in the field application, which has played an important role in ensuring the reliable operation of GIS equipment. [0003] UHF sensor is a key device in UHF detection, and its performance directly determines the detection sensitivity and effective detection range. Insufficient sensitivity or effective detection range of the sensor will lead to missed reports of potential insulation discharge faults, sensor failure or even self-discharge will directly lead to false alarms of potential insulation discharge faults, seriously affecting use. Therefore, in order to ensure the ef...
