Abstract

The invention provides a 110KV total drop main transformer oil chromatography online monitoring and analyzing system, and relates to the field of transformer oil chromatography online monitoring. The 110KV total drop main transformer oil chromatography on-line monitoring and analyzing system comprises a transformer body device, an oil chromatography on-line monitoring device, a fluorescent optical fiber on-line temperature measuring device and a main control computer device, and the fluorescent optical fiber on-line temperature measuring device comprises an optical fiber temperature sensor and an optical fiber temperature controller. The oil chromatography on-line monitoring device comprises an analyzing module for gas dissolved in oil, an on-line monitoring module for micro-water content in oil and a chromatographic analyzing and diagnosis module. The oil chromatography on-line monitoring device can be used for monitoring fault gas dissolved in multi-component and full-component oil at the same time, can assist in realizing on-line analyzing of micro-water in oil, and can automatically realize the functions of data acquisition, chromatogram analyzing, fault diagnosis and the like; and the temperature and the variation trend of the transformer winding can be monitored on line in real time through the fluorescent optical fiber on-line temperature measuring device, and beforehand management and risk prediction are achieved.

Description

technical field [0001] The invention relates to the technical field of on-line monitoring of transformer oil chromatography, in particular to an on-line monitoring and analysis system for oil chromatography of a 110KV total drop main transformer. Background technique [0002] With the development of the economy, the demand for power is getting stronger and stronger, the scale of the power grid is constantly expanding, the structure of the power grid is becoming more and more complex, and the requirements for power supply reliability are getting higher and higher, which requires online monitoring of substations. High-voltage, large-capacity power transformers are the most critical equipment in power transmission and transformation systems, and they will be affected by various factors such as electricity, heat, machinery, and the environment during actual operation. Therefore, the necessary monitoring of high-voltage power equipment to ensure its stable operation is of great s...
