Abstract
The invention discloses a protective structure for an American box type transformer. The protective structure is a cover fixedly installed above an oil tank between a high-voltage chamber and a low-voltage chamber of the American box type transformer. The cover is made of metal, and the upper surface of the cover forms a gradient from the center to the outside. The protective structure makes rainwater and snow water flow away easily, dust accumulation is greatly reduced, corrosion and rusting of parts on the lower portion are eliminated, and the protective structure is resistant to theft.
Description
Technical field
The present invention relates to a kind of safeguard structure, particularly relate to a kind of safeguard structure applied on U.S.'s change case.
Background technology
American Unit Substation because of its compact conformation, floor space is few, transmission capacity is moderate, easy for installation at power supply transmission facility and photovoltaic, be widely applied in wind power generation, be widely used in various construction environment.Also just because of this feature, in road on both sides of the road, limit, mountain, side, river, pool, limit, tunnel face, the also a large amount of American Unit Substation of construction deployment under the various comparatively harsh natural conditions such as wind-powered electricity generation and photovoltaic, Desert of Gobi or sandy beach, island.
Because American Unit Substation does not structurally make targeted design for the application under comparatively harsh natural conditions when designing traditionally, this just causes long-term U.S. that uses in these natural environments to become, many remarkable or potential problems can be caused, especially dust storm, sleet, chronic sun exposure etc. cause product local or general corrosion, get rusty, be out of shape, the problem such as brittle, make properties of product cannot meet application requirement and even cannot apply; Meanwhile, also easily occur in some areas under field condition that being taken apart top cover by robber steals the copper cash of device body inside and the hidden danger of other precious metals.
Summary of the invention
For the deficiencies in the prior art, applicant carefully analyzes, deeply consider the beautiful multiple natural causes becoming case and easily cause burn into damage etc. in application process, issue clear a kind of safeguard structure not changing the beautiful prerequisite becoming case body construction, the U.S. that can effectively prevent from sleet from piling up causing becomes case top cover and corrodes; In further improvement of the present invention, have also been devised theft-prevention structure targetedly, improve the fail safe of application.
Specifically, the present invention is achieved through the following technical solutions:
A kind of U.S. change case safeguard structure, this safeguard structure is be fixedly installed in the cover cap above the beautiful fuel tank become between the hyperbaric chamber of case and low-pressure chamber, and this cover cap adopts metal material to make, and its upper surface outwards forms the gradient from center.
By said structure, the protruding shape in middle part is processed in cover cap middle part, makes can not assemble when there being sleet to land cause corrosion but outwards scatter, and greatly reduces dust alluvial, eliminates each component corrosion and get rusty.
Wherein, the concrete degree of convexity of cover cap can carry out Reasonable adjustment as required.Applicant is through a large amount of construction verification, and preferred cover cap center is 3 ~ 5 degree relative to the gradient at edge.
Under above-mentioned inclination angle, not only can significantly suppress rainwater to be piled up, and cover cap mid portion can be made to produce internal stress, under larger load condition can be born after bending forming, not produce permanent deformation, be conducive to the work such as people can directly carry out above lifting, installation.
Wherein, cover cap can adopt suitable metal material to make according to applied environment, usually adopts cold-rolled steel sheet to make; The area such as on coastal, island, can adopt stainless steel material to make, spray antiultraviolet paint after surface of stainless steel spray coating powder paint again, play the effect of anti-Exposure to Sunlight, sand-proof, sleet.
In the present invention, the thickness of cover cap is flexible and changeable, and preferably, the thickness of cover cap is not higher than 3mm, and more preferably its thickness is 2 ~ 3mm, and the intermediate raised portion mated with it is 30 ~ 40mm relative to the height at cover cap edge.
In order to prevent seashore salt fog, acid rain, strong sunlight, frequently expose to wind and rain etc. and become the corrosion of case fuel tank top cover and the impact of sealing thereof to U.S., cover cap edge has downward cover plate, and the degree of depth of this cover plate at least can cover fuel tank top cover four sides bolt, fuel tank top cover connects seal with box flange.
By said structure, whole head cover of transformer position encases by safeguard structure, improves its useful life and sealing; Meanwhile, make again beautiful become case outward appearance more coordinate, unified, attractive in appearance.
In further architecture advances of the present invention, also disclose the fixed form of above-mentioned safeguard structure, cover cap edge has the wing plate towards hyperbaric chamber and low-pressure chamber, be the mounting edge of perpendicular web in wing plate end, this mounting edge adopts bolt arrangement to be fixedly connected with hyperbaric chamber with the sidewall of low-pressure chamber respectively.
Further, bolt arrangement used is cup head square neck screw, and the round head of cup head square neck screw is positioned at the outer avris of installation.
Improved by said structure, after adopting stainless steel cup head square neck screw to install, cannot dismantle outside, play anti-theft function.
Accompanying drawing explanation
Fig. 1 is safeguard structure schematic perspective view of the present invention;
Fig. 2 is safeguard structure installment state schematic diagram of the present invention;
Fig. 3 A, 3B are respectively the close-up schematic view of I, II part of the safeguard structure of installation.
Embodiment
In following, applicant has carried out more detailed description to safeguard structure of the present invention by reference to the accompanying drawings.The following concrete enforcement provided is only schematic, does not form the present invention and is particularly limited to; The accompanying drawing provided is also non-proportionally to be drawn, and those skilled in the art are adjusting, ratio, material etc. on the basis understanding invention essence of the present invention.
With reference to accompanying drawing 1, safeguard structure of the present invention, adopt 2 ~ 3mmQ-235 cold-rolled steel sheet to be made into cover cap 1, process projection in the centre of cover cap, this protruding opposing cover edge has the inclination angle of 3 ~ 5 degree; Having downward cover plate 4 in the surrounding of cover cap, have the wing plate 2 towards hyperbaric chamber and low-pressure chamber in the relatively hard-wired both sides of the edge of cover cap, is the mounting edge 3 of perpendicular web in wing plate end.
With reference to figure 2, show the mounting means of safeguard structure of the present invention on U.S.'s change case, this safeguard structure is installed on above the beautiful fuel tank become between the hyperbaric chamber A of case and low-pressure chamber B, mounting edge 3 is fixed by bolt arrangement I with the sidewall panel of hyperbaric chamber A and low-pressure chamber B respectively, bolt arrangement used is cup head square neck screw 5, and the round head of cup head square neck screw is positioned at the outer avris of installation (with reference to figure 3A), the surrounding of installing rear cover has downward cover plate 4 and can cover fuel tank top cover four sides bolt, fuel tank top cover connects seal (with reference to II part in figure 2 with box flange, Fig. 3 B's covers schematic diagram).Safeguard structure of the present invention cannot be dismantled outside, has anti-theft feature.
Improved by said structure, safeguard structure of the present invention can play rainproof, the effects such as sand-proof, anticorrosion, anti-theft, and installs simply, safely, reliably.
