Description
Technical field
It the utility model is related to transformer test technical field, and in particular to a kind of to solve the problems, such as the dress of transformer partial discharge
Put.
Background technology
With the fast development of China's power industry, AC input transformation voltage class also gradually steps up, to power transmission and transforming equipment
The requirement of reliability also more and more higher.Induced over voltage withstand test is used to verify transformer in operating conditions without shelf depreciation, for
Guarantee transformer can safely and reliably be run under long-term work voltage to play an important roll.
Transformer is during the manufacturing, because design deficiency of product, insulating materials local defect, process time be not true
The factors such as fixed, human users, shelf depreciation can not meet standard or protocol requirement during Transformer Plant Test.People is tested at this stage
Member is according to partial discharge quantity with distribution of pulses on the change of test voltage height, hysteresis effect, test voltage waveform etc. come really
Determine the possible physical property of shelf depreciation.And the shelf depreciation in insulation system is also likely to be because insulation torrefaction or immersion oil do not fill
Caused by point, current most companies, which are pressurizeed after the hot-oil circulation, handles that insulating part immersion oil is impermeable to ask by the way of quiet put
Topic, but is not impregnated with due to product structure, insulation thickness and completely the factors such as position, DeGrain, and process cycle is long.
The content of the invention
In view of the above-mentioned problems, the utility model offer is a kind of to solve the problems, such as the device of transformer partial discharge.
To solve the above problems, the technical scheme that the utility model is taken is：It is a kind of to solve the problems, such as the dress of transformer partial discharge
Put, including oil filter, transformer body, intermediate transformer, generator and nitrogen cylinder, described transformer body high-pressure side difference
Intermediate transformer high-pressure side is connected to by three-phase bus, intermediate transformer low-pressure side is connected to generating by three-phase bus respectively
Machine, transformer body medium voltage side are connected to oil filter oil-feed by bus short join, transformer body top oil-out by pipeline
Mouth, transformer body bottom oil inlet are connected to oil filter oil-out by pipeline, and transformer body inflation inlet passes through blast pipe
It is connected to nitrogen cylinder exhaust outlet.
Distance is not more than 10m between control oil filter and transformer body, ensures deep fat effect.
The utility model is for transformer is due to insulation torrefaction or immersion oil is insufficient causes shelf depreciation to meet to check and accept
The problem of standard, proposes a solution, winding is heated, hot-oil circulation and pressurization it is quiet put combination, make coil from inside to outside
Heating keeps certain temperature, accelerates deep fat wetting-out rate and effect, transformer is transported into experiment station after end entered by quiet put
Row local discharge test, demonstrate the feasibility and actual effect of the device.More conventional pressurization is quiet to put mode, and the device is exhausted in processing
Edge is dry or immersion oil is insufficient when causing partial discharge problem that effect becomes apparent from, and greatly shortens processing time.

Embodiment
As described in Figure, it is a kind of to solve the problems, such as the device of transformer partial discharge, including oil filter 1, transformer body 2, middle anaplasia
Depressor 3, generator 4 and nitrogen cylinder 5, the described high-pressure side of transformer body 2 are connected to middle transformation by three-phase bus respectively
The high-pressure side of device 3, the low-pressure side of intermediate transformer 3 are connected to generator 4 by three-phase bus respectively, and the medium voltage side of transformer body 2 leads to
Bus short join is crossed, oil-out 21 is connected to oil filter oil inlet 12, transformer body bottom by pipeline at the top of transformer body
Oil inlet 23 is connected to oil filter oil-out 11 by pipeline, and transformer body inflation inlet 22 is connected to nitrogen cylinder by blast pipe
Exhaust outlet 51.
Distance is not more than 10m between control oil filter 1 and transformer body 2.
Generator 4 is heated by mode of loading to Transformer Winding, and control generator 4 applies electric current and is equal to application electricity
Press the 1/3 of winding rated current, it is ensured that ensure heating effect while safe, while heat is carried out to transformer using oil filter 1
Oil circulation, it is 65 DEG C to control the oil temperature of oil filter oil-out 11, when a length of 8h-10h of heat cycles.
Using nitrogen cylinder 5 transformer pressurize after heat cycles it is quiet put, keep the top pressure of transformer body 2 to be
0.03Mpa-0.05Mpa, it is quiet to put 24h, further consolidate dielectric and be impregnated with effect.
