Switch cabinet insulation defect type detection method, device, equipment and program product

Abstract

The invention relates to a switch cabinet insulation defect type detection method, device, equipment and program product. The method comprises the following steps: acquiring detection data of target gas in a target switch cabinet, wherein the detection data comprises the concentration of the target gas, the generation rate of the target gas and the temperature of the target switch cabinet; inputting the detection data into a target support vector machine to obtain a detection result of the target support vector machine; the detection result is the insulation defect type of the target switch cabinet; wherein a kernel function parameter and a penalty parameter of the target support vector machine are obtained based on a cross validation algorithm. By adopting the method, insulation defect type detection can be carried out on the switch cabinet under the conditions that the method is not easily interfered by external environmental factors and the detection precision is improved.

Description

technical field [0001] The present application relates to the technical field of electrical equipment detection, in particular to a method, device, equipment and program product for detecting insulation defect types of switch cabinets. Background technique [0002] As an important power distribution equipment, the switchgear plays an important role in the power system. However, the switchgear works in harsh environments such as high temperature, high pressure, and humidity for a long time, and it is easy to induce failure due to the degradation of insulation performance. Once the switchgear fails, it may not only cause damage to other important equipment on the line, but also more likely cause a power outage. Therefore, it is necessary to analyze the types of insulation defects of the switchgear in order to maintain the switchgear according to different types of insulation defects and prevent major accidents. [0003] In the prior art, when a switchgear failure occurs, dat...
