Fig. 1-4 is please referred to, the present invention is the following technical schemes are provided: a kind of loaded voltage-regulating power with conservator defencive function
Transformer, including conservator cylinder 1, are equipped with capsule mechanism 2 in the inner cavity of conservator cylinder 1, capsule mechanism 2 include the first capsule 21,
Second capsule 22 and third capsule 23, third capsule 23 are set in the outside of the second capsule 22, and the second capsule 22 is set in first
The outside of capsule 21, exhaust pipe 5 is fixedly installed at the top center of conservator cylinder 1, and capsule mechanism 2 passes through exhaust pipe 5 and oil
It rests the head on cylinder 1 to be tightly connected, the first capsule 21 is communicated by connecting tube with respirator 6 through exhaust pipe 5.
In the present embodiment, by being arranged to capsule mechanism 2 by the first capsule 21, the second capsule 22 and 23 groups of third capsule
At, enhance the intensity of capsule mechanism 2, due between third capsule 23 and the second capsule 22 for be tightly connected, only pass through first
Capsule 21, the second capsule 22 are communicated with respirator 6, reduce the area that air is entered by respirator 6 in capsule mechanism 2, drop
The probability that low insulating oil is contacted with air is ruptured by being equipped with fitting part 8 in the outside of the second capsule 22 in third capsule 23
When, 23 rent of third capsule is shunk, and is contacted with the second capsule 22, and pass through magnetic block 4 on third capsule 23 and the
Iron block 41 on two capsules 22, so that the second capsule 22 is bonded with third capsule 23, and since cross sticker closes item 81 and perpendicular patch
It closes item 82 to be made of cohesive material, and cross sticker closes item 81 and is higher than magnetic block 4 and iron block 41 with the perpendicular height for being bonded item 82, so that the
The rent of three capsules 23 is adhesively fixed with the second capsule 22, to be connected and sealed, reduces gas in third capsule 23
The discharge of body.
Specifically, third capsule 23 and the second capsule 22 are tightly connected, the first capsule 21 passes through regulating part 7 and the second capsule
22 communicate；Regulating part 7 is for protecting the first capsule 21, when the oil temperature oil level of conservator cylinder 1 rises rapidly, by the
Three capsules 23 and the second capsule 22 squeeze the first capsule 21, when the air pressure in the first capsule 21 is excessively high, have little time in time
When discharge, portion gas can be transported in the second capsule 22 by regulating part 7, prevent the rupture of the first capsule 21.
Specifically, regulating part 7 includes through-hole 71 and attachment base 72, attachment base 72 is fixedly mounted in through-hole 71, attachment base
Oily spring 73 is fixedly mounted in 72 sides far from the first capsule 21, and the other side of spring 73 is fixedly connected with movable plate 74, even
The right side of joint chair 72 is fixedly installed with fixing seat 75, and the outside of movable plate 74 is fixedly installed with elastic projection 76, in fixing seat 75
Equipped with groove compatible with elastic projection 76, movable plate 74 engages sealing with fixing seat 75 by elastic projection 76, groove and connects
It connects；The gas of first capsule 21 stretches out groove by squeezing movable plate 74, by the elastic projection 76 on movable plate 74, to will move
Movable plate 74 is separated with fixing seat 75, so that the gas in the first capsule 21 is transported in the second capsule 22, prevents the first capsule
The first capsule 21 is protected in 21 rupture.
Specifically, the second capsule 22 is adhesively fixed with fitting part 8 with 23 opposite side of third capsule, if fitting part 8 includes
Dry cross sticker closes item 81 and perpendicular fitting item 82, and setting that cross sticker closes item 81 and perpendicular fitting item 82 intersects, cross sticker is closed item 81 and erected
Fitting item 82 is made of cohesive material；When third capsule 23 ruptures, 23 rent of third capsule is shunk, and due to cross sticker
It closes item 81 to be bonded item 82 with perpendicular and be made of cohesive material, so that the rent of third capsule 23 carries out be bonded consolidate with the second capsule 22
It is fixed, to be connected and sealed, reduce the discharge of gas in third capsule 23.
Specifically, third capsule 23 and 22 opposite side of the second capsule are fixedly installed with magnetic block 4, set on the second capsule 22
There is iron block 41 compatible with magnetic block 4, third capsule 23 is connect by magnetic block 4, iron block 41 with 22 magnetism of the second capsule；In
When third capsule 23 ruptures, 23 rent of third capsule is shunk, and is contacted with the second capsule 22, and can pass through third capsule 23
On magnetic block 4 and the second capsule 22 on iron block 41 so that the second capsule 22 is bonded with third capsule 23, cross sticker closes item
81 are higher than magnetic block 4 and iron block 41 with the perpendicular height for be bonded item 82, the gluing to the second capsule 22 and third capsule 23 that be fitting part 8
It taps into row to pull, provides better laminating condition for fitting part 8.
Specifically, the bottom of conservator cylinder 1 offers feculence box, set that there are two guide plates 3 in the inner cavity of conservator cylinder 1；
Guide plate 3 is for being oriented to the greasy dirt of 1 bottom of conservator cylinder.
The working principle of the invention and process for using: gas replacement is carried out with respirator 6 by the first capsule 21, is reduced
Air enters the area in capsule mechanism 2 by respirator 6, the probability that insulating oil is contacted with air is reduced, when conservator cylinder 1
Oil temperature oil level when rising rapidly, first capsule 21 is squeezed by third capsule 23 and the second capsule 22, when the first glue
Air pressure in capsule 21 is excessively high, and when having little time to be discharged in time by respirator 6, the gas of the first capsule 21 is by squeezing movable plate
74, the elastic projection 76 on movable plate 74 is stretched out into groove, movable plate 74 is separated with fixing seat 75, thus by the first capsule 21
Interior gas is transported in the second capsule 22, prevents the rupture of the first capsule 21, when third capsule 23 ruptures, third capsule 23
Rent is shunk, and is contacted with the second capsule 22, and passes through the iron on the magnetic block 4 and the second capsule 22 on third capsule 23
Block 41, so that the second capsule 22 is bonded with third capsule 23, and since cross sticker closes item 81 with the perpendicular item 82 that is bonded as sticky material
Material is made, and cross sticker closes item 81 and is higher than magnetic block 4 and iron block 41 with the perpendicular height for being bonded item 82, so that the rent of third capsule 23
It is adhesively fixed with the second capsule 22, to be connected and sealed, reduces the discharge of gas in third capsule 23.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
