Description
Technical field
The present invention relates to a kind of power transformer, belong to transmission of electricity power transformer technology field.
Background technology
Power transformer is one of important operational outfit of electric power system, and its normal operation will be played important impact to the safety of electrical network.But transformer is in the middle of operation, and owing to being inevitably subject to the impact of the various factorss such as electricity, heat, vibration, environment, ageing of insulation, its technical performance is constantly deteriorated, and running status will be received impact.And oil-immersed type transformer is a most widely used class in power transformer field at present, it utilizes insulating oil as dielectric, an important indicator as insulating capacity quality is gas componant and the content in insulating oil, as the content height of the compositions such as hydrogen, carbon dioxide will directly cause the lower performance of doing of insulating oil.Conventionally, when carrying out the composition of insulating oil and content measurement, adopt Oil chromatography analysis, by analyzing oil and gas separator, extract oil gas sample, sample is carried out to chromatography, thereby realize the composition measurement of insulating oil, middle gas content detects.Existing checkout equipment is bulky, carries inconvenience, and testing crew can only regularly arrive collection in worksite single sampling, then in laboratory, measure, and operation procedure is complicated, and analysis time is long, and expense is higher, cannot find in time especially latency fault and effectively follow the tracks of development trend, in addition, this detection method workload is large, and efficiency is low, often occur, to the failing to judge of fault, causing equipment operation failure.
Simultaneously, because power transformer usage quantity is huge, distributed pole is wide, therefore currently only can rely on periodic inspection and safety test as the Main Means of transformer safe operation, but because the time between overhauls(TBO) is long, existing preventive trial project is insensitive to the developing fault reaction of transformer, not in time, often in fault, within raw several days, to several weeks, could find, and to local glitch, it finds that difficulty is larger, therefore usually cause occurring various faults (as crossed superheating, discharge fault, overheated double discharge fault, mechanical breakdown etc.) and major accident, cause part and even large-area power-cuts, cause huge direct and indirect economic loss and social influence.Therefore,, in the urgent need to advanced technological means, transformer is carried out to on-line monitoring effectively, grasp in real time the running status of transformer, with maintenance targetedly, replace periodic inspection, reduce loss of outage, realize the safe operation target that initial failure is reported to the police, avoided serious accident to occur.
