Description
Technical field
The present invention relates to a kind of computer management method, relate in particular to a kind of method that is applicable to the insulating oil qualitative control of power industry.
Background technology
Insulating oil is to make the basic guarantee that oil-filled electrical equipment can operate as normal.Customary insulation oil is the mineral oil of from oil, separating, and principal ingredient is alkane (C
nH
2n+2), the stable hydrocarbon (C of cyclic hydrocarbon family
nH
2n), aromatic series unsaturated hydrocarbon (C
nH
2n-2).Generally, under the effect of crossing heat effect or electricity, the insulating oil in the electrical equipment can wear out and decompose gradually, produces a spot of gas simultaneously.The physics of insulating oil, chemistry, electric property can descend to some extent.And when when hiding in the equipment fault being arranged, speed aging and gasification takes place insulating oil will accelerate.Just because of variation and oil product degradation, fault type and the order of severity of the composition of failure gas, oil have close ties; So in the operational process of electrical equipment; Regularly insulating oil is carried out gas and oil quality analysis in the oil; The inner latency fault of discovering device as early as possible is to avoid causing damage of electrical equipment accident.The patent No. is that the Chinese patent document of ZL200920108305.9 has been introduced a kind of method that adopts on-line chromatograph that transformer oil is monitored.But this method only contains a kind of electrical equipment of transformer, therefore also only pays attention to the stratographic analysis of simple a kind of transformer oil, pays close attention to very few to the physical performance index of common insulating oil self and the variation of chemical property index and electricity function index.The more important thing is that said method is based on the experimental result under the time point through the running status of chromatography analysis and judgment electrical equipment, to the operation trend of electrical equipment, particularly the development trend of latency fault owes accurately and judges.
Summary of the invention
The technical matters that the present invention will solve is; Deficiency to the prior art existence; A kind of insulating oil quality control method is provided; Use this method management insulating oil quality both to comprise that the management to the insulating oil oil dissolved gas also comprised the management to insulating oil oil, the incipient fault of ability identification, early warning and processing insulating oil quality proposes diagnostic comments; Effectively prevent the generation of failure of insulation accident, be suitable for especially a large amount of real time datas that on-line condition monitoring system of intelligent transformer station records are managed.Only compare with classical management approach based on the running status that makes chromatograph experimental result judgement electrical equipment under the time point; It is more comprehensive to use this method to contain the insulating oil quality; The operation trend that can reflect electrical equipment, institute's data that obtain are more reliably safer, inquire about faster.
