Abstract
The present invention relates to a kind of oil conservater, specifically a kind of compensation temperature changes and causes the capsule-type full sealed non-maintenance oil conservater of transformer oil Volume Changes, belongs to the part of transformer.It is made up of outer cabinet, inner cabinet, capsule, recycle oil oil inlet pipe, oil level indicator, Buchholz relay union, recycle oil flowline, recycle oil oil filler, blow vent etc..Maximum difference with general capsule type oil storage cabinet is to eliminate dehydrating breather, add the hot-oil circulation system being made up of outer cabinet, inner cabinet, recycle oil oil inlet pipe, recycle oil flowline etc., there is recycle oil miscarriage life in transformer station high-voltage side bus, oil conservater temperature can be lifted, make that aqueous water will not be produced in the capsule of oil conservater, while circulate the presence of Oil Tank recycle oil stream and the rise of the temperature of oil conservater is advantageous to the radiating of transformer.It is non-maintaining that the present invention can realize capsule type oil storage cabinet, improves the safety operation level of oil conservater and transformer.
Description
Technical field
The present invention relates to a kind of Large Oil immersion transformer, more particularly to a kind of oil storage of Large Oil immersion transformer
Cabinet.
Background technology
Transformer oil storage mainly has three kinds at present, is that diaphragm type storage oil cabinet, capsule type oil storage cabinet, wavy metal are swollen respectively
Expanding oil conservater.The price of wavy metal expansion type oil-storage cabinet is about three times of other two kinds of oil conservater prices or so, metal
The ripple core body of corrugated expansion oil conservater causes grave gas protection act and makes change being also easy to produce play in the process of running
Depressor trips, and ripple core body occurs during seepage that the replacement cost very high time is long, cost is very high in the process of running, and this storage
Oil Tank time of occurrence is not grown, and is tested without the life-cycle.Diaphragm type storage oil cabinet is easy due to the poor sealing between upper and lower two cabinets
Seepage and water inlet, gradually eliminate.Capsule type oil storage cabinet needs to configure dehydrating breather, and dehydrating breather needs to regularly replace silica gel, because
This is not non-maintaining product.Dehydrating breather easily blocks simultaneously, causes transformer unsmooth breath, causes transformer oil spout or negative pressure.Separately
Although outer capsule type oil storage cabinet is configured with dehydrating breather can not prevent aqueous water generation in capsule completely, in some cases glue
Intracapsular moisture can also be cumulative.
The content of the invention
The problem of present invention exists for existing capsule type oil storage cabinet, adds hot-oil circulation system.During transformer station high-voltage side bus
Caused heat, the temperature of transformer oil are significantly larger than the temperature of environment, deep fat are introduced to the hot-oil circulation system of oil conservater, greatly
Amplitude lifts the temperature of oil conservater, the Daily minimum temperature in oil conservater capsule is higher than the daily temperature maximum temperature of external environment,
Therefore capsule will not produce condensation water, can cancel dehydrating breather, reduce the workload of periodic replacement dehydrating breather silica gel, make
Oil conservater becomes non-maintaining product, can so improve the property safe and reliable to operation of capsule type oil storage cabinet.Simultaneously because oil conservater
Temperature increase substantially, constantly outwardly distribute heat, the heat-sinking capability of transformer can be improved.
Brief description of the drawings
Fig. 1：Profile of the present invention
Fig. 2：The present invention and the hot-oil circulation system diagram of transformer body
Embodiment
Referring to Fig. 1, oil conservater of the present invention by outer cabinet 1, inner cabinet 2, capsule 3, recycle oil oil inlet pipe 4, oil level indicator 5, watt
This relay union 6, recycle oil flowline 7, recycle oil oil filler 8, blow vent 9 form.
Referring to Fig. 2, cavity, recycle oil oil inlet pipe 4, recycle oil flowline between outer cabinet 1 and inner cabinet 2 of the invention
7 with transformer body 13, recycle oil inlet valve 11, recycle oil delivery valve 12, form oil conservater hot-oil circulation system.
When transformer oil temperature changes, transformer oil causes Volume Changes because of the effect of expanding with heat and contract with cold, and transformer oil leads to
Cross Buchholz relay 10 and Buchholz relay union 6 passes in and out the inner cabinet 2 of oil conservater, cause the oil level of inner cabinet 2 of oil conservater
Change, so as to realize the regulation of transformer oil volume, oil level indicator 5 is used to indicate oil level.Capsule 3 is floated on transformer oil, will be become
Depressor oil is isolated with outside air, and the air and moisture for preventing the external world contact with transformer oil, influence the property of transformer oil
Energy.Blow vent 9 be used for enable when oil level change the external world air free in and out capsule 3, make inside capsule 3 with the external world always
Keep identical pressure.
Oil conservater of the present invention has recycle oil oil-feed by forming a cavity between outer cabinet 1 and inner cabinet 2 on outer cabinet
Pipe 4 and recycle oil flowline 7, recycle oil oil filler 8.Recycle oil oil filler 8 is used to fill change for oil conservater hot-oil circulation system
Depressor oil.Recycle oil oil inlet pipe 4 is connected with the recycle oil inlet valve 11 on the top of transformer body 13, recycle oil flowline 7 with
The recycle oil delivery valve 12 of the bottom of transformer body 13 is connected.During transformer station high-voltage side bus, because transformer oil is because of heated generation pair
Stream acts on and produces circulation oil stream（Or produce circulation oil stream in the driving effect of forced oil-circulation system）.Circulation oil stream makes
The temperature of oil conservater rises, and capsule 3 is higher than the daily maximum temperature of external environment condition due to temperature, and inside will not produce aqueous water.
Oil conservater circulation oil stream makes the rise of the temperature of oil conservater be advantageous to the radiating of transformer simultaneously.
