Characteristics Testing And Running State Analysis Of Transformer Substation Equipment

All the time since, the power of this energy is an integral part of life, with therapid development of society, the power development is also much attention in allaspects. The whole power system, composed of power generation, transmission,substation, distribution, in a substation, transformer, circuit breaker, busbar, lightningarrester and CT, TA and so on is the main equipment in substations, the running stateof these devices is how, in relation to the safe, stable operation of the whole powersystem, so it is necessary analysis of these features of the equipment, monitoringrunning state, timely know and master the condition of the equipment, to ensure thatthe safety of the transformer substation, and the stability of the power system. Insubstation, the main transformer system is the hub, it is be different voltage gradelines connected together with equipment, distribution of power and the transformationof voltage and current role.Through the monitoring data of transformer, the analysis of the running state ofthe transformer and makes the maintenance of judgment and decision, is conducive tothe production staff, arrange production plan scientifically, reduce the accidents. Wecollected data, analysis of data through a number of methods to draw conclusion. Theresearch of transformer partial discharge signal detection, can effectively andcorrectly recognize the partial discharge patterns of normal and transformer insulationdefects, prevention and diagnosis of power transformer fault to. Test Research ondeformation of transformer winding machine, can get the degree of deformation oftransformer windings. Through the analysis of gas in transformer oil and transformerpreventive insulation failure mode analysis, obtains the necessity of oil transformeroverhaul or action, while the gas in oil analysis can reduce the transformer test times,and can effectively provide maintenance time, and prevent the accident of transformer,improve the preventive maintenance of power transformer.These years, the power industry operation and scientific research departmentsattach great importance to the condition assessment of power transformer, but also at home and abroad from twentieth Century80time begin then conducted a lot ofresearch work, proposes the related intelligent technology of many kinds of faultdiagnosis and fault prediction, but in practical application can get promotion, most ofthe researches are still building in the stage of exploration theories and models, thereare few forming practical system is very successful.This paper presents a new analysis method in the analysis and fault diagnosis oftransformer condition, can be very good to be combined with the data of equipmentmonitoring history and many experts experience, development status analysis oftransformer fault can be dynamic, and provide repair decision for productionpersonnel.
