A single-function online monitoring system can only monitor a single or partial insulation parameter of a type of equipment, such as a chromatographic device specially used to monitor transformer oil or a partial discharge device specially used to monitor transformers. With the continuous development of technology, various single-function online monitoring systems tend to be integrated. The monitoring units of various substation equipment are connected to the host computer through the field bus. The monitoring unit is responsible for data collection, preliminary analysis, and uploads the data to the monitoring system. The upper computer and the host computer further process the data, uniformly generate graphics and reports, and store the data in the database. The formation of the comprehensive online monitoring system for substation equipment has realized the real-time online monitoring function for substation transformers, reactors, circuit breakers, GIS, high-voltage bushings, capacitive equipment and other substation equipment.
考虑到状态检修工作的开展现状,许多评价工作实际上不可能完全由自动化完成,仍然需要专业人员的参与。Considering the current status of condition-based maintenance work, many evaluation tasks cannot be completely automated, and still need the participation of professionals.
