Abstract
The invention discloses a diaphragm type oil conservator, which comprises an upper flange installed at the bottom of an upper conservator body, a lower flange positioned at the top of a lower conservator body and a diaphragm arranged between the upper flange and the lower flange. An upper sealing part tightly abutting against the upper flange and the diaphragm and a lower sealing part tightly abutting against the lower flange and the diaphragm are arranged in vertical symmetry mode. At least two pairs of symmetrical protrusions extending outwards are arranged on the top surfaces and the bottom surfaces of the upper sealing part and the lower sealing part. An upper limit strip and a lower limit strip which are used for limiting positions are respectively arranged on two sides of the upper sealing part and the lower sealing part. Partial return stroke spaces for the upper sealing part and the lower sealing part are large, and relative offset is avoided.
Description
Technical field
The present invention relates to the hermetically-sealed construction of diaphragm type storage oil cabinet
Background technology
The hermetically-sealed construction of existing diaphragm type storage oil cabinet; The end face of last seal, lower seal and bottom surface are the plane, because the direction of principal axis of oil conservator is longer, upper flange, lower flange welded and installed can deform later on cabinet; The faying face of upper flange and last seal, lower flange and lower seal can form uneven gap like this; Inhomogeneous easy generation deformation of the compression stress that causes seal, lower seal to bear or relativity shift, and it is less to go up the local backhaul space of seal, lower seal, seal part are prone to follow the string can't resilience; Sealing effectiveness is relatively poor, and oil seepage phenomena takes place oil conservator easily
Summary of the invention
the purpose of this invention is to provide the big sealing effectiveness in a kind of backhaul space hermetically-sealed construction of diaphragm type storage oil cabinet preferably.
are for achieving the above object; The present invention provides a kind of hermetically-sealed construction of diaphragm type storage oil cabinet; Said oil conservator comprises cabinet and lower cabinet body; Said hermetically-sealed construction comprises and being oppositely arranged; Be installed in the said upper flange of going up bottom of cabinet bulk and the lower flange that is installed in said lower cabinet body top, be arranged on be used between said upper flange and the said lower flange to separate said on cabinet and said lower cabinet body barrier film, push against said upper flange and said barrier film be used to support said upper flange on seal, push against said lower flange and said barrier film the lower seal that is used to support said lower flange, be adjacent to be arranged on said on the seal both sides be used to limit the position the upper limit bar, be adjacent to and be arranged on the lower limit bar that said lower seal both sides are used to limit the position, said on seal, said lower seal align setting and end face and bottom surface up and down and have laterally zygomorphic outward extending at least two pairs of convexities.
preferably, said both sides of going up seal, said lower seal are respectively upwards and extend to form two pairs of convexities downwards.
are because the technique scheme utilization; The present invention compared with prior art has advantage and effect: outward extending at least two pairs of convexities that symmetry is set in last seal, lower seal end face and bottom surface; Be provided for limiting upper limit bar, the lower limit bar of position respectively in last seal, lower seal side; Go up seal like this, the lower seal reset capability is better; When being compressed power local backhaul space big and when receiving uneven compression stress relative position can not squint, sealing effectiveness is better, oil conservator is difficult for taking place oil seepage phenomena.
Description of drawings:
accompanying drawing 1 is looked cross-sectional schematic for master of the present invention.
Embodiment:
Referring to shown in Figure 1, diaphragm type storage oil cabinet comprises the lower cabinet body 8 of splendid attire transformer oil, link to each other with the external world and play the respiratory cabinet 7 of going up, and the barrier film 3 between last cabinet 7, the lower cabinet body 8 makes transformer oil and air separation; Install flange 1 in last cabinet 7 bottoms, lower flange 2 is installed at lower cabinet body 8 tops, because diaphragm type storage oil cabinet direction of principal axis distance is longer; So after installing; Upper flange 1 can deform with lower flange 2, between upper flange 1 and barrier film 3, seal 5 is set, and end face, the bottom surface of last seal 5 makes progress, extends to form at least two pairs of convexities that push against upper flange 1 and barrier film 3 respectively downwards; Between barrier film 3 and lower flange 2, lower seal 4 is set; End face, the bottom surface of lower seal 4 make progress respectively, extend to form at least two pairs of convexities that push against barrier film 3 and lower flange 2 downwards, lower seal 4, the compression of going up lower flange 2 and upper flange 1 after seal 5 is out of shape respectively, and protruding existence can change lower seal 4, go up the compression ratio of seal 5; Effective seal clearance of make lower seal 4, going up seal 5 is apart from increasing; Be that local backhaul space is strengthened, lower seal 4, to go up the ability that resets after seal 5 is compressed better, and receiving after the bigger uneven compression stress not can can't resilience because of following the string; For avoiding seepage oil; The lower seal 4 of barrier film about in the of 3, go up seal 5 and must align, be adjacent to lower seal 4, go up seal 5 both sides lower limit bar 6, upper limit bar 9 are set respectively, like this after receiving uneven compression stress; Relativity shift can not take place in lower seal 4, last seal 5, and the present invention has prevented that effectively the oil seepage phenomena of diaphragm type storage oil cabinet or outer water from getting into the phenomenon in the transformer oil
Claims (2)
1. the hermetically-sealed construction of a diaphragm type storage oil cabinet; Said oil conservator comprises cabinet and lower cabinet body; It is characterized in that: said hermetically-sealed construction comprises the said upper flange of going up bottom of cabinet bulk of being installed in of being oppositely arranged and the lower flange that is installed in said lower cabinet body top, be arranged on be used between said upper flange and the said lower flange to separate said on cabinet and said lower cabinet body barrier film, push against said upper flange and said barrier film be used to support said upper flange on seal, push against said lower flange and said barrier film the lower seal that is used to support said lower flange, be adjacent to be arranged on said on the seal both sides be used to limit the position the upper limit bar, be adjacent to and be arranged on the lower limit bar that said lower seal both sides are used to limit the position, said on seal, said lower seal align setting and end face and bottom surface up and down and have laterally zygomorphic outward extending at least two pairs of convexities.
2. the hermetically-sealed construction of diaphragm type storage oil cabinet according to claim 1 is characterized in that: said both sides of going up seal, said lower seal respectively upwards and extend to form two pairs of convexities downwards.
