Abstract
The utility model discloses a large-sized transformer oil conservator oil storage device allowing accessory replacement without oil drainage, which comprises a vacuum oil filter. An oil sample valve at the bottom of a large-sized transformer and an oil conservator on the top of the large-sized transformer are respectively communicated with two ends of the vacuum oil filter by vacuum-resistant oil pipes. The large-sized transformer oil conservator oil storage device adopts the vacuum oil filter to drain insulating oil inside the large-sized transformer, temporarily uses the oil conservator as an oil reservoir, and facilitates rapid replacement of related accessories.
Description
One. technical field:
The utility model relates to a kind of attending device of high-power transformer, particularly relates to the conservator Fuel Tanking Unit that annex is changed in a kind of not oil extraction of high-power transformer.
Two. background technology:
Sustained and rapid development along with national economy, China's power industry presents the trend of sustained and rapid development, the application of various high-power transformers is more and more, and in use, local damage can appear in high-power transformer, need to change corresponding accessory, common way is: according to the overhaul installation procedure, discharging transformer body insulating oil is changed corresponding accessory then earlier, this both waste of manpower, material resources influence the index of system reliability again.
Three. the utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of simple in structure, conservator Fuel Tanking Unit that annex is changed in not oil extraction of high-power transformer that efficient is high and easy to operate is provided.
The technical solution of the utility model is: the conservator Fuel Tanking Unit of annex is changed in a kind of not oil extraction of high-power transformer, contain vacuum oil-filter, described vacuum oil-filter two ends are communicated with the oil sample valve of high-power transformer bottom and the conservator at high-power transformer top respectively by the vacuum-resistant oil pipe.
The beneficial effects of the utility model are:
1, the utility model has not only reduced maintenance workload, has shortened interruption duration, and owing to does not expose the iron core of transformer, the availability coefficient and the fail safe that improve transformer equipment.
2, the utility model adopts vacuum oil-filter that the insulating oil of high-power transformer inside is extracted out, and makes conservator as interim oil conservator, is convenient to change fast corresponding accessory.
3, the utility model is simple in structure, efficient is high and easy to operate, and it is applied widely, has good economic benefit after the popularization.
Four. description of drawings:
Fig. 1 is a structural representation of the present utility model.
Five. embodiment:
Embodiment: referring to Fig. 1, among the figure, 1-high-power transformer, 2-conservator, 3-vacuum-resistant oil pipe, 4-vacuum oil-filter, 5-oil sample valve.
The conservator Fuel Tanking Unit that annex is changed in not oil extraction of high-power transformer contains vacuum oil-filter 4, and these vacuum oil-filter 4 two ends are communicated with the oil sample valve 5 of high-power transformer 1 bottom and the conservator 2 at high-power transformer 1 top respectively by vacuum-resistant oil pipe 3.
In use, if damaging appears in the A place annex of high-power transformer 1, if this annex is directly changed in not oil extraction, the insulating oil in the high-power transformer 1 will flow out from this.Install and startup vacuum oil-filter 4, make conservator 2 as interim oil conservator, valve closing between this moment conservator 2 and high-power transformer 1 body, open the venting plug exhaust of conservator 2 in the time of oil pumping, and pull down the exhaust of main conservator silica gel tube, after conservator 2 is filled with oil, close venting plug, just can change the corresponding accessory at A place.
Maintenance finishes, at first the high-power transformer body is carried out one hour vacuumizing from the Buchholz relay interface, open the valve between high-power transformer 1 and the conservator 2 then, make the oil in the conservator 2 flow into the high-power transformer body, exhaust successively from low to high, after oiling finished to the high-power transformer body, once more to the exhaust of high-power transformer body, air entered the harmful effect to high-power transformer in the elimination maintenance process.
Claims (1)
1. the conservator Fuel Tanking Unit of annex is changed in a not oil extraction of high-power transformer, contain vacuum oil-filter, it is characterized in that: described vacuum oil-filter two ends are communicated with the oil sample valve of high-power transformer bottom and the conservator at high-power transformer top respectively by the vacuum-resistant oil pipe.
