Online intermittent monitoring method for power transmission and transformation equipment, medium, sensor and analysis station

Abstract

The invention discloses an online intermittent monitoring method for power transmission and transformation equipment, a medium, a sensor and an analysis station. The method comprises the steps that the sensor presets an intermittent mode; at a time node, the sensor collects a partial discharge signal of the equipment and uploads the partial discharge signal to the analysis station; the analysis station separates the partial discharge signals, extracts abnormal signals from the partial discharge signals, and analyzes the abnormal signals to judge whether alarm conditions are met or not; after the alarm condition is determined to be met, an alarm message containing abnormal signal analysis data is generated, and the alarm message is uploaded to a workstation; and the workstation overhauls the equipment according to the alarm message until the alarm is released. The sensor presets the intermittent mode, so that the sensor intermittently collects partial discharge signals of equipment, thesensor does not need to be in a working state all the time, on one hand, the service life of the sensor is obviously prolonged, and on the other hand, energy consumption and enterprise cost are remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of on-line monitoring of power transmission and transformation equipment, in particular to a method, a medium, a sensor and an analysis station for on-line intermittent monitoring of power transmission and transformation equipment. Background technique [0002] The on-site online monitoring of power transmission and transformation equipment can monitor the state quantities of real-time data in real time, thereby forming an informationized condition-based maintenance decision-making system. How to perfect the on-site on-line monitoring system of power transmission and transformation equipment is an urgent problem that needs to be solved urgently in the industry. At present, the on-site on-line monitoring system of power transmission and transformation equipment mostly uses sensors to collect partial discharge signals of the equipment. The sensors in the prior art are usually in the working state all the time,...

AI Technical Summary

Problems solved by technology

At present, the on-site online monitoring system of power transmission and transformation equipment mostly uses sensors to collect the partial discharge signal of the equipment. The existing technology sensors are usually in the working state all the time, that is, the sensor continuously and uninterruptedly collects the partial discharge signal of the equipment. On the one hand Equipment abnormalities do not occur frequently, so keeping the sensor in working condition will cause unnecessary energy consumption to a certain extent. On the other hand, the sensor is always in working condition, which will have a greater impact on the service life of the sensor
