Abstract

The invention discloses a method and system for detecting ultraviolet discharge degree by means of set indexes. The method comprises the following steps of: S1, acquiring a discharge video of an insulator chain; S2, acquiring at least two set indexes from the discharge video; and S3, separately acquiring the detection result of the ultraviolet discharge degree according to a relation between each set index and a corresponding index threshold, wherein the insulator chain is in a severe discharge state if any detection result indicates that the insulator chain is in a severe discharge state. The method and system for detecting the ultraviolet discharge degree by means of the set indexes may well indicate the discharge degree of the insulator chain.

Description

technical field [0001] The invention relates to the technical field of ultraviolet detection, in particular to a method and system for detecting the degree of ultraviolet discharge by using a set index. Background technique [0002] Ultraviolet detection technology is a non-contact live detection technology gradually developed in recent years. It can detect the severity of discharge and insulation performance by detecting the specific band of ultraviolet light generated by the discharge of power insulation equipment. In the prior art, the two main data obtained by ultraviolet detection are the number of ultraviolet photons and the area of ​​ultraviolet spot, but only based on the above two values, the discharge status of the insulator string cannot be well characterized, which poses a threat to the further application of ultraviolet detection technology and Promotion creates obstacles. Contents of the invention [0003] The purpose of the present invention is to propose a...
