Description
Technical field
The utility model relates to transformer equipment, is specifically related to a kind of transformer breather.
Background technology
Respirator is an attached safety guard of oil filled transformer, is arranged on the pipe end of conservator and air UNICOM, and when oil temperature changed, conservator top layer gas, by respirator and atmosphere UNICOM, kept stable gas pressure.The built-in discolour silica gel of respirator, during ambient atmos process silica gel, the steam in gas, by silica gel absorption, keeps gas drying in conservator.When silica gel becomes pale red by blue look, show that silica gel makes moist, moisture pick-up properties reduces, and must change or drying.Changing silica gel is a regular maintenance work, and change once general approximately 1.5-February, and silica gel is changed frequent, and maintenance cost is high.
When transformer in service is changed silica gel, to change heavy protection into signalling by tripping operation before changing, need can change weight gas into tripping operation by signalling through 24 hours after changing silica gel.Heavy gas is one of transformer main protection, it withdraw from the safe operation that will have a strong impact on transformer, and during this period,, if the transformer internal abnormality easily makes fault coverage enlarge, even damage transformer, cause heavy economic losses.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, the transformer breather before improving, comprise silica gel tank 01 and lubricating cup, wherein, the interior placement discolour silica gel 02 of silica gel tank 01, the following one deck screen pack 03 of laying of discolour silica gel 02, silica gel tank 01 bottom has aperture; Lubricating cup is comprised of outer lubricating cup 06 and interior lubricating cup 07, and interior lubricating cup 07 is communicated with silica gel tank 01 small hole at bottom part, and interior lubricating cup 07 bottom is provided with interior lubricating cup bottom outlet 09, is provided with outer lubricating cup pore 05 on outer lubricating cup 06 sidewall, and the lubricating cup bottom is placed with sealing oil 08.Ambient atmos, from outer lubricating cup 06, sealing oil 08, interior lubricating cup 07, then passes through discolour silica gel 02 successively, and the steam in gas is adsorbed by discolour silica gel 02, keeps gas drying in conservator.When silica gel becomes pale red by blue look, show that silica gel makes moist, must change or drying.Changing silica gel is a regular maintenance work, and change once general approximately 1.5-February, and silica gel is changed frequent, and maintenance cost is high.
As shown in Figure 2, the respirator after improvement has bellows 11 at described lubricating cup outside cover, and bellows 11 1 ends are by silica gel tank 01 two bottom sides
Baffle plateWith the sealing of silica gel tank, the other end is provided with elastic block piece 12, and outer lubricating cup 06 bottom is equipped with travel switch 10, on the baffle plate of silica gel pot bottom one side, electromagnetically operated valve 04 is installed, and electromagnetically operated valve 04 is controlled by travel switch 10.
Specific implementation process:
As shown in Figure 2, transformer Long-time Shut-down or when the oil temperature fluctuation was very little while entering steady operational status, this moment, travel switch 10 was failure to actuate, electromagnetically operated valve 04 is failure to actuate.Bellows 11 is with ambient atmosphere and the interior isolated from atmosphere of bellows 11, and conservator internal gas pressure minor fluctuations will compensate by the flexible of bellows 11.Because the interior gas moisture of bellows 11 is very low, silica gel is extended useful life.
When transformer start stop operation, load variations are large, when variation of ambient temperature is larger, if continuous negative pressure in this moment conservator, bellows 11 is contracted to extreme position (as shown in Figure 3).Bellows 11 bottom touching travel switches 10, at this moment as shown in Figure 5, travel switch relay T 10 turn-on time, time relay time delay break contact is connected electromagnetically operated valve 04, electromagnetically operated valve 04 action, with ambient atmosphere and the inner UNICOM of bellows 11, bellows 11 stretching, extension automatically under self elastic force effect.The effect of time relay T is that assurance electromagnetically operated valve 04 is opened the regular hour, allows bellows 11 fully unfold to free state.
If continuous malleation in conservator, bellows 11 extends to extreme position (as shown in Figure 4).Bellows 11 bottom elastic block pieces 12 are opened downwards, and gas is discharged from bellows 11.When bellows 11 internal gas pressures were consistent with ambient pressure, elastic block piece 12 was closed automatically.
After using the utility model respirator, the cycle of changing silica gel is by extending to the 6-8 month in 1.5 months.
To sum up, the utility model accomplishes the end in view.
