Description
Technical field
The invention belongs to mechanical structure field, relates more specifically to a kind of oil conservator used for transformer capsule breakage monitoring dress
Put.
Background technology
Transformer oil storage capsule, is widely used in power system transformer, and it is cut-off transformer oil and air that it, which is acted on,
Contact, prevent the oxygen in air and moisture from immersing in oil, preventing transformer oil that oxygen aging or deterioration, resistivity occurs reduces, is situated between
Damage rise, protects transformer not corroded by oxious component, increases the service life.
, due to a variety of causes, damaged, leakage be present in production, transport, installation, running in transformer oil storage capsule
The situation of gas.After capsule occurs damaged, the effect of cut-off transformer oil and air contact will be lost, transformer oil passes through run-down
Place flows into capsule, and air then enters the cavity of capsule and oil storage pillow, causes transformer oil air content, moisture progressively to increase
Add, cause transformer oil oxygen aging or deterioration, resistivity reduce, dielectric loss raises.And air enters the sky of capsule and oil storage pillow
After chamber, expand when transformer oil temperature raises, because this partial air is difficult to leak into air in time from breakage, occupy
The useful space of oil conservater, the transformer oil for causing entry into capsule overflow from dehydrating breather, or pressure increase, pressure release
Valve events, the security incident event of transformer tripping operation.Lack very much this measure taken precautions against security incident now, this turns into
The emphasis of people's research now.
The content of the invention
It is contemplated that overcome the shortcomings of above-mentioned technology, there is provided a kind of oil conservator used for transformer capsule breakage monitoring device,
By setting monitoring device, it can detect whether capsule type oil storage cabinet breakage occurs, timely processing defect, this avoid transformation

Method directly observes the problem of capsule breakage air inlet situation.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of oil conservator used for transformer capsule breakage monitoring device is provided, described device includes oil conservater, capsule, union, oil level
Meter and dehydrating breather, the capsule are provided with the cavity for being used for filling transformer oil reservoir in oil conservater, inside the oil conservater
Structure；Described capsule one end is connected with oil conservater, the bottom of the other end floats on the surface of transformer oil reservoir；The capsule passes through
Union is connected with dehydrating breather, and the dehydrating breather is on the outside of oil conservater；Described device includes monitoring modular, and the monitoring modular is set
At the top of oil conservater, the monitoring modular includes being used to sense the float of pressure change and float in oil conservater and is used to send alarm
Alarm structure, the float is in the cavity body structure.
The present invention is by being set using monitoring device so that the oil conservater capsule breakage monitoring device, it is damaged using capsule
Afterwards, air accumulates on oil conservater top, drives the principle of float movement, and buoyancy of the float in oil, in air is different, measurement storage
Oil Tank whether air inlet, to judge whether capsule breakage occurs, triggering alarm structure sends signal, realizes the damaged monitoring of capsule.
The present invention can detect whether capsule type oil storage cabinet breakage occurs, timely processing defect, this avoid transformer by setting
Oil by sunlight aging, deterioration, reduce sealing surface, solve hermetically sealed capsule type oil storage cabinet and take all-metal construction, can not
The problem of directly observing capsule breakage air inlet situation.Capsule of the present invention is communicated by connecting leg and dehydrating breather with extraneous air, capsule
Bottom surface be close to pasta and float in oil conservater.By the mode such as being vented, vacuumizing, make there is no air between collapsible bag and pasta,
Completely cut off contact of the pasta with air, prevent oil from aoxidizing, make moist, contaminated purpose so as to can reach.When pasta becomes with temperature
During change, capsule also expands and compressed therewith, serves the effect of breathing.
Wherein, the oil level indicator is located at oil conservater sidepiece bottom.It should be noted that this is simply preferred, it is not limit
The regulation of property processed.
In addition, the oil conservater bottom is provided with the oil note valve for oil charging-discharging.It is for the ease of oil charging-discharging so to set.
Wherein, the air relief cock for deflating is provided with the top of the oil conservater.So setting is the original according to air up
Reason is arranged at top, it is necessary to which explanation, this is restricted explanation.
In addition, the monitoring modular includes gear pair, bevel gear pair, active magnet steel, the driven magnet steel being sequentially connected with, it is described
Gear pair is connected with float.The present invention isolation of realization device metal sealing, is avoided using active magnet steel, the structure of driven magnet steel
Turned position poor sealing leakage of oil.Moved by driven magnet steel, trigger alarm structure, reach monitoring capsule with the presence or absence of breakage
Purpose.
Wherein, the oil conservater is provided with metal shell structure.The hermetically sealed capsule type oil storage cabinet of the present invention takes all-metal
Shell mechanism, it is in order to which transformer oil storage capsule is in production, transport, installation, running, due to various originals so to set
Cause, damaged, gas leakage be present.
In addition, the capsule is the square structure that both ends are provided with circular arc.So set that to avoid the occurrence of angle pressure big, easily
It is damaged.
Wherein, the oil conservater is connected by union with dehydrating breather, and the oil conservater is communicated with valve with union junction
Door.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention is by being set using monitoring device so that the oil conservater capsule breakage monitoring device, it is empty after capsule breakage
Gas accumulates on oil conservater top, drives the principle of float movement, buoyancy of the float in oil, in air is different, measures oil conservater
Whether air inlet, to judge whether capsule breakage occurs, triggering alarm structure sends signal, realizes the damaged monitoring of capsule.This hair
It is bright to detect capsule type oil storage cabinet and breakage whether occur by setting, timely processing defect, this avoid transformer oil by
Sunlight aging, deterioration, reduce sealing surface, solve hermetically sealed capsule type oil storage cabinet and take all-metal construction, can not be direct
The problem of observing capsule breakage air inlet situation.Oil conservater capsule appearance of the present invention is damaged, and the transformer oil in oil conservater progressively oozes
Enter oil conservater capsule, air enters the space of oil conservater and collapsible bag, and is accumulated on oil conservater top.Float is with oil storage
Air is continuously increased in cabinet, and pasta declines and reduced, and is driven gear pair, bevel gear pair, active magnet steel, driven magnet steel to rotate, is touched
Send out alarm structure and send alarm signal, realize monitoring function.
