Abstract

The invention discloses an on-line detection method for surface pollution of metal oxide arresters, comprising the following steps: S1. Obtaining the full leakage current i from metal oxide arresters with different surface pollution levels t and input voltage U. The on-line detection method for surface contamination of the metal oxide arrester only needs to collect the full leakage current and voltage of the metal oxide arrester in operation, decompose the full leakage current through the algorithm proposed in the present invention and extract features, and finally pass the Gaussian The Yes classifier classifies the surface contamination degree of the arrester corresponding to the full leakage current, which is very convenient to grasp the surface contamination of the metal oxide arrester, which greatly improves the service life of the arrester and the reliability of the power system operation. The online detection can eliminate the power failure caused by the power failure maintenance, avoid the process of loading and unloading the arrester, and improve the convenience of the detection process.

Description

technical field [0001] The invention relates to the technical field of arrester detection, in particular to an on-line detection method for surface contamination of a metal oxide arrester. Background technique [0002] Reliable and uninterrupted power generation and transmission are the most important needs of global social development. Usually, in the case of lightning weather or switching surge voltage, the insulation system of power system equipment will bear huge pressure, which may lead to the explosion of insulation equipment. or catastrophic failure. Metal oxide arrester is an insulating device that protects power system equipment from lightning and switching surges by absorbing excess energy like overvoltage and reducing its magnitude to below a safe threshold. The role in the power system insulation system is crucial. [0003] Metal oxide arresters can be considered as insulators in normal operation, however the insulating properties may be affected by different i...
