Application And Analysis Of On-line Monitoring System For Transformers

The oil chromatogram analysis of gas dissolved in oil is important way to detecting fault inside a transformer. With the development of power grid and the boost of operating voltage, the technology of oil chromatogram concerned gas dissolved in oil are improving gradually, developing from conventional method to on-line monitoring method which is adopted now.This thesis expounds the mechanism of system of gas dissolved gas in oil production and oil chromatographic fractions and fault types, combined with the present application situation in condition based maintenance of power grid in chromatographic analysis, expounds the necessity and basic principle of transformer online monitoring. Through the application tests and comparative analysis of transformer oil chromatogram on-line monitoring technology in power grid, demonstrates the implementation scheme and device of transformer online monitoring system of the main technical indicators, for power grid enterprises in the equipment bid and provide technical reference data in bidding.
