Description
Technical field
The utility model relates to a kind of testing transformer, is specifically related to a kind of testing transformer of simulating multiple iron core and winding failure.
Background technology
In the development in past 10 years, China's power construction fast development, has made brilliant achievements.Wherein, capacity of installed generator rapid growth, power grid construction speed is advanced by leaps and bounds, structure adjustment of power source is continued to optimize, technical equipment significantly promotes, energy-saving and emission-reduction consumption reduction effect is remarkable, and power construction has realized great-leap-forward development, and such development has proposed higher challenge to the safe operation of electrical network.As one of most important equipment in electric power system, transmitting, flexible allocation and the safe and reliable use of the normal operation of power transformer to electric energy plays conclusive effect.The safe operation of electric power system and maintenance are the coefficient results of plurality of devices, and therein, power transformer belongs to value costliness but acts on a class large and that involve many areas, is therefore significant for the research that ensures its safe operation.Only consider from economic aspect, the 250MVA/500kV transformer of import is approximately 1,330,000 dollars/platform on average, domestic same specification also reach about 1,000 ten thousand yuan/platform.When the power transformer of the operation of having put into production when burst accident, may cause casualties and cause having a power failure on a large scale in running.In addition, as large scale electrical power unit, once damage, possible maintenance cycle may reach half a year or more than, therefore need to seek transmission capacity of instead of transformers or this transformer station of corresponding reduction etc., involve scope extremely wide, make a very bad impression, spending a large amount of manpower and materials, is in power system operation, to need to do one's utmost to avoid.
Repair based on condition of component is that current practical working situation taking equipment is as foundation, carry out the state of judgment device by advanced status monitoring means, reliably evaluation means and the predicting means in life-span, position, the order of severity and the development trend that can occur fault judge, can make up " maintenance is superfluous " of the periodic maintenance of traditional main employing taking the time as standard and the defect of " maintenance is not enough ", at present, the State Maintenance of power transformer is the study hotspot problem of power direction.
But transformer is a complicated system, be operated under the electric and mechanical environment of load, inner aging, failure mechanism is complicated, has uncertainty, and the key that equipment carries out repair based on condition of component is undoubtedly to the extraction of fault characteristic signals and the setting of failure criterion.At present, varied for the condition detection method of transformer, there are vibration analysis method, oil chromatography analysis, dielectric loss detection, partial discharge monitoring, frequency sweep impedance method etc.No matter be to utilize what principle to carry out status monitoring to transformer, be all a kind of means, what reach the same goal by different routes is to extract the characteristic value that can distinguish fault type for different faults, and determines fault alarm threshold value accurately.Therefore, design one and can simulate multiple transformer fault, and the fault characteristic signals extracting under different faults type in conjunction with various the study of the monitoring methods as platform is very important.
External fault is the various faults that occur on oil tank of transformer exterior insulation sleeve pipe and lead-out wire thereof, its main Types has: insulating sleeve flashover or ground short circuit broken and that occur, phase-to phase fault etc. occurs between lead-out wire and cause power transformer interior fault or winding deformation etc.
Internal fault is the various faults that occur in oil tank of transformer, and its main Types has: turn-to-turn short circuit, winding or the lead-out wire occurring between the phase fault occurring between each winding, the wire turn of winding is by shell generation earth fault etc.Because transformer fault involvement aspect is wider, the dividing mode of particular type is more, if divide from the agent structure of transformer, can be divided into traditionally winding failure, iron core fault, shunting switch fault and other annex fault.
Although the kind of transformer fault is various, but the probability that all kinds of faults occur is different, the domestic demonstration of the calendar year statistics data about transformer, winding and shunting switch are the more parts that break down, in fault rootstock, 53% belongs to mechanical breakdown, and 31% belongs to electric fault.For the transformer that does not have on-load tap changer, statistics finds that 26.6% fault comes from winding failure, and 6.4% fault is attributed to iron core fault simultaneously.And also there is similar conclusion in foreign scholar's correlative study, B.Sparling provides in his research report, Years Of Service distributes in the fault of the large-scale power transformer of 15 years to 25 years, it is the principal element that causes transformer cisco unity malfunction that fault and iron core fault are polluted in winding deformation fault, insulation, therefore develops that one can be simulated winding failure and iron core fault is extremely urgent.
