Problems solved by technology

[0004] However, at present, the condition-based maintenance of GIS equipment is carried out mainly through on-line monitoring methods such as partial discharge and leakage current to judge its insulation performance. A perfect GIS equipment status evaluation model. At the same time, in the daily management of equipment, the professional work lacks contact, and it is impossible to effectively integrate the daily maintenance, test reports, operation data, and maintenance records of the equipment. There is a lack of a relatively complete summary,

Abstract

The invention provides a GIS (Gas Insulated Switching gear) equipment condition assessment method and system. The method comprises the steps: receiving a condition assessment instruction, and obtaining related data from a grid production management system and a GIS partial discharge on-line monitoring system according to the assessment instruction; quantizing, classifying and filing the obtained data to obtain basic data, insulation performance data, operating mechanism data, attachment data, running record data and accident defect maintenance data, and storing all the data; assessing the running performance of GIS equipment at present and within some time to come according to the stored various kinds of data; and determining the probability of failure of the GIS equipment at present and within some time to come according to the running performance and the accident defect maintenance data. The related data is conveniently and fast obtained in real time, the GIS equipment condition of a GIS is comprehensively and objectively assessed based on the obtained data, and the assessment efficiency is high.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a GIS equipment state evaluation method and a GIS equipment state evaluation system. Background technique [0002] With the continuous expansion of the grid scale, the security and economy of the power system are facing greater challenges. GIS (Gas Insulated Switchgear, SF 6 Gas-insulated fully enclosed combiner) is a high-voltage electrical device that seals and combines electrical components such as circuit breakers, isolating switches, fast earthing switches, current / voltage transformers, lightning arresters, bus bushings and / or cable terminals on grounded metal Enclosure to SF 6 A complete system in which gas is used as the insulating medium. Compared with conventional electrical appliances, GIS equipment has the advantages of small footprint, convenient installation, not easily affected by the external environment, high operational reliability, and long maintenanc...
