GIS (Gas Insulated Switching gear) equipment condition assessment method and GIS equipment condition assessment system

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.
