Summary of the invention
The purpose of this utility model is to provide the Transformer fuel tank that a kind of simple in structure, intensity improves, uses safety, life.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of Transformer fuel tank, comprise casing, casing is with the opening that makes progress, and the opening periphery of casing is connected with the case edge, and case is along being structure as a whole with casing, case is connected with case lid by case along bolt along top, case lid and case along between be provided with seal gasket, it is characterized in that: the case lid periphery is connected with bending side, bending side and case lid are structure as a whole, seal gasket is positioned at the space of bending side and case lid formation, and the lower sideline of bending side is not higher than the least significant end of case along bolt.
According to described Transformer fuel tank, it is characterized in that: the centre is high in the longitudinal direction, two ends are low for described case lid.
According to described Transformer fuel tank, it is characterized in that: the junction of described bending side and described case lid is arcwall face.
According to described Transformer fuel tank, it is characterized in that: the angle of described bending side and horizontal plane is 60 °.
According to described Transformer fuel tank, it is characterized in that: be installed with the phase sequence identification board by described case along bolt above described case lid, the wherein part of phase sequence identification board covers on described bending side.
the cover structure of the main centering Tanks of Distribution Transformer of the utility model has carried out brand-new design, traditional plate armature is improved to case lid edge band bending side, simple in structure, practical and attractive, intensity obviously improves on the basis that does not increase the case lid steel plate thickness, accomplished rationally to fall material, and reduced accidental injury in the equipment conveying process, use safety, seal gasket is protected in the space of bending side formation, can effectively avoid exposing to the weather and drench with rain, extend the operation of power networks maintenance period and increased the operational reliability of transformer, greatly extend useful life.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
A kind of Transformer fuel tank, as depicted in figs. 1 and 2, comprise casing 1, casing 1 is with the opening that makes progress, the opening periphery of casing 1 is connected with case along 2, case is structure as a whole with casing 1 along 2, case is connected with case lid 7 by case along bolt 5 above 2, case lid 7 and case are provided with seal gasket 6 between 2, case lid 7 peripheries are connected with bending side 3, bending side 3 is structure as a whole with case lid 7, and seal gasket 6 is positioned at the space of bending side 3 and case lid 7 formation, and the lower sideline of bending side 3 is not higher than the least significant end of case along bolt 5.The centre is high in the longitudinal direction, two ends are low for case lid 7.Bending side 3 is arcwall face with the junction of case lid 7.Bending side 3 is 60 ° with the angle of horizontal plane.Be installed with phase sequence identification board 4 by case along bolt 5 above case lid 7, the wherein part of phase sequence identification board 4 covers on bending side 3.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design concept; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model; all should fall into protection range of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
The utility model has solved and has relied on single increase case lid steel plate thickness to improve intensity, shortens the problems such as maintenance period because of the damage of body seal rubber cushion because of improper stressed case lid distortion and the Transformer of causing of case lid in transformer assembling and transportation.
Case lid in the utility model is when making, first with four arm of angle corner cut 50mm * 50mm of original case lid, chamfered in four limits, then with the four edges downward bending, bend in opposite directions processing to both sides centered by axis by corresponding mould at short-axis direction, be limited with 1.5%～2%, and high in the middle of being on long axis direction, two ends are low, heat-treat solid type after completing.So both can cover case edge and seal gasket, and also not hinder install bin along bolt, more resident without the rainwater dust.
In manufacturing process, guarantee case lid and case in the reasonable installation distance, horizontal by 60 ° of angles and bending side lower limb line and case along the fair requirement in the position of bolt, determining the case lid size according to case lid edge bending side.Calculate the bending degree of depth according to bending line and goniometer, select suitable cutting die according to steel plate thickness and bending length, complete on the folder that fully satisfies nominal pressure or Digit Control Machine Tool.
After case lid and case are joined along trial assembly, drill the bolt hole on fixing case lid, case edge on drilling machine.
When the transformer general assembly, phase sequence identification board one end is fixed according to sign content institute cursor position along bolt by case, and posted on bending side.
After case lid bending in the utility model, when improving case lid intensity, can correspondingly reduce the actual (real) thickness of case lid steel plate, to reduce consumables cost.Due to the raising of intensity and the effect of bending side, reduced in transformer assembling and transportation, the case that causes because of the improper stressed steel plate deformed that causes of case lid and because of shearing force is along the damage risk of bolt; In addition, due to blocking of downward bending part, effectively reduce the aging speed of seal gasket, the corresponding cycle of operation that extends transformer, reduced user's maintenance cost.Case lid bulk strength after the edge bending increases, and is not prone to the metabolies such as alice, wave, and when being subject to facing collision directly, stress vector is diminished.
In addition, the utility model thoroughly changed in appearance the vertical element moulding of transformer and case along bolt expose mixed and disorderly, making the phase sequence identification board (is high-pressure side A phase/B phase/C phase/0 phase, low-pressure side a phase/b phase/c phase) change setting-in on bending side into from case lid plane setting-in, make it very clear on visual effect, more easy to identify, reduce erroneous judgement.
