Improvement of the gas chromatographic method for diagnosing developing defects in oil-filled electrical equipment based on the analysis of furan compounds

During the operation of oil-filled electrical equipment under influence temperature, humidity and other negative factors, destruction paper insulation occurs. As a result this destruction, furan compounds are formed, which get into transformer oil. To identify process insulation, control in oil is carried out by instrumental methods. Of these methods, most widely used gas chromatography using packed chromatographic columns, on basis guidelines have been developed. improve methods for monitoring compounds, we highly efficient quartz capillary column filled with polar stationary phase based polyethylene glycol. The sample was injected injector chromatograph Chromos-GC1000 an automated dosing system vial 23 samples. Used GK-1 brand Almetyevsk networks taken as object research; optimal retention characteristics standard sorbates were preliminary determined, organic extractants compounds. effect temperature analysis furfuryl alcohol it established that selectivity separation determined nature intermolecular interactions sorbate-sorbent system, particular, formation hydrogen bond. It has shown coefficient depends physicochemical extractants, their boiling points dipole moments highest values analyzed pair components: - ethanol.
