Abstract
The utility model discloses a bell type tank grounding structure which is characterized in that grounding screws are respectively welded on box edges of an upper-section oil tank and a lower-section oil tank, a copper bar is used as a connecting bridge for connecting the grounding screws on the upper box edge and the lower box edge, the copper bar is of a strip plate shape, screw holes are formed in the grounding screws, and the copper bar is fastened on the grounding screws by using screws. The bell type tank grounding structure has the beneficial effects that firstly, a large-size U-shaped copper bar is not needed to be connected, the connecting copper bar used by the novel structure is small in size and short in length, and thus raw materials are saved, and the cost is lowered; secondly, the manufacture process is simple, the bell type tank grounding structure can be used as a general part, and thus the production efficiency is increased; and thirdly, grounding plates are not welded on the box walls of the upper-section oil tank and the lower-section oil tank, and thus the appearance attractiveness of a transformer is improved.
Description
Technical field
The utility model belongs to the oil tank of transformer field, relates to a kind of bell type tank ground structure.
Background technology
Present stage, on bell-jar, the lower oil tank ground structure is 2 ground plates of welding on upper lower oil tank tank wall, then connects with U-shaped copper bar, and copper bar specification used is large, length is long, and cost is high; U-shaped connection copper bar manufacturing process is complicated, can not be as general part, and production efficiency is low; Ground plate is welded on tank wall, and weld seam is obvious, has affected transformer appearance looks elegant degree.
Summary of the invention
The utility model provides a kind of bell type tank ground structure simple in structure, esy to use, safe and reliable in order to make up the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
Bell type tank ground structure of the present utility model, its special character is: the case of upper lower oil tank along on weld respectively grounding screw, then with copper bar as the grounding screw that connects bridge and connect upper nowel edge; Copper bar is long strip-board shape, with screw, with screw, copper bar is fastened on grounding screw on grounding screw, realizes that lower oil tank reliably connects.
Bell type tank ground structure of the present utility model, preferred version be, on 4 limits on the case edge of upper lower oil tank, each welds 4 grounding screws.
The beneficial effects of the utility model are:
1. do not need again to connect with the U-shaped copper bar of large specification, existing new construction connection copper bar used, specification is little, length is short, has saved raw material, has reduced cost.
2. manufacturing process is simple, can be used as general part, has improved production efficiency.
3. need not up weld ground plate on the lower oil tank tank wall again, improve the aesthetics of transformer outward appearance.
Description of drawings
Fig. 1 is the front view schematic diagram of traditional structure, and Fig. 2 is the schematic top plan view of Fig. 1, and Fig. 3 is front view schematic diagram of the present utility model, and Fig. 4 is the schematic top plan view of Fig. 3.
In figure: oil tank on 1,2 ground plates, 3 U-shaped connection copper bars, 4 lower oil tanks, 5 bolts, 6 grounding screws, 7 copper bars.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Bell type tank ground structure of the present utility model, the case of upper lower oil tank along on weld respectively grounding screw, then with copper bar as the grounding screw that connects bridge and connect upper nowel edge; Copper bar is long strip-board shape, with screw, with screw, copper bar is fastened on grounding screw on grounding screw, realizes that lower oil tank reliably connects.On 4 limits on the case edge of upper lower oil tank, each welds 4 grounding screws, namely go up oil tank all around case along 1 grounding screw of each welding, lower oil tank all around case along 1 grounding screw of each welding.
Bell type tank ground structure of the present utility model, by upper lower oil tank case along on weld grounding screw, connecting with copper bar.Because grounding screw is welded on case along upper, shortened the length that connects copper bar, saved raw material, improved the aesthetics of transformer outward appearance.
Claims (2)
1. bell type tank ground structure is characterized in that: the case of upper lower oil tank along on weld respectively grounding screw, then with copper bar as the grounding screw that connects bridge and connect upper nowel edge; Copper bar is long strip-board shape, with screw, with screw, copper bar is fastened on grounding screw on grounding screw.
2. bell type tank ground structure according to claim 1 is characterized in that: on 4 limits on the case edge of upper lower oil tank, each welds 4 grounding screws.
