Abstract

The invention relates to a cloud service-based partial discharge transient-stage earth electric wave cloud detection method and device, wherein the method comprises the steps of: acquiring an earth electric wave signal; conducting filtering, amplification, analog-to-digital conversion to the acquired earth electric wave, wherein the analog-to-digital conversion consists of the steps of: rectifying a preset square wave signal into a direct current signal, comparing the direct current signal with the amplified earth electric wave, and reading the amplified earth electric wave by applying a binarization reading method; sending the digital earth electric wave to a cloud service side, conducting data processing to the digital earth electric wave through the cloud service side, and judging whether partial discharge occurs; and receiving the processed data returned by the cloud service side and a judgment result, displaying the processed data, and prompting according to the judgment result. The invention provides a detector accordingly. The method and device can overcome the defects that the on-site background noise is greatly influenced, and the data processing is complicated through the existing TEV partial discharge inspection, and improve the computation speed of the device and detection accuracy on partial discharge.

Description

Technical field [0001] The invention relates to a partial discharge detection technology for high-voltage equipment, in particular to a partial discharge transient radio wave cloud detection method and device based on cloud services. Background technique [0002] Partial discharge is mainly caused by the internal insulation of switchgear, transformers and other high-voltage electrical equipment under the action of high voltage. Research has found that nearly 85% of electrical accidents are caused by partial discharge. With the rapid development of my country’s power industry and the continuous deepening of the construction and transformation of urban and rural power grids, the requirements of social development and progress on the stability and reliability of power supply have also been increasing. It is necessary to accurately grasp the health status of high-voltage equipment and formulate correct maintenance measures to avoid The occurrence of unexpected accidents caused by the ...
