Abstract
The utility model relates to a voltage transformer tube structure. The voltage transformer tube structure is composed of an upper flange, an end socket, a straight tube and a lower flange, wherein the upper flange, the end socket, the straight tube and the lower flange are sequentially connected in welding mode. The upper end edge and/or the lower end edge of the end socket are provided with straight-tube-shaped straight edge structures. The straight edge of the upper end of the end socket is connected with the upper flange in welding mode, and the straight edge of the lower end of the end socket is connected with the straight tube in welding mode. Compared with a traditional tube structure, straight-tube-shaped straight edge structures are adopted on the upper end and the lower end of the end socket, the voltage transformer tube structure is simple in structure, and an upper round and a lower round are both provided with straight edges bringing convenience to welding and alignment. Thus, the voltage transformer tube structure can improve welding efficiency and finished product rates, good in manufacturability and attractive in tube appearance.
Description
Technical field
The utility model relates to a kind of voltage transformer tube structure.
Background technology
Voltage transformer is metering and protection equipment important in the electric power system; the cylindrical shell of voltage transformer mainly is welding structure; as shown in Figure 1; it is mainly by upper flange 1; pulling out a mouthful 2(is end socket), straight tube 3 and lower flange 4 form, and four parts are weldingly connected in turn; traditional mouthful end socket that pulls out is designed to spherical crown shape or dish (as shown in Figure 2), and I, II, III are position while welding among the figure.Because the voltage transformer cylindrical shell adopts whole welding structure, this just needs each part that certain matching relationship is arranged each other, but spherical seal head is not because the great circle place has straight flange, with be difficult for centering during straight tube is docked, welding process perpendicularity and circularity are wayward, and easily play fold after pulling out mouthful employing cold-drawn processing, affect the overall appearance effect of product.
The utility model content
The purpose of this utility model provides a kind of voltage transformer tube structure, to solve existing tube structure welding process perpendicularity and the uppity problem of circularity.
For achieving the above object, the utility model adopts following technical scheme: a kind of voltage transformer tube structure, by upper flange, end socket, straight tube and lower flange form, and four parts are weldingly connected in turn, and the upper end of described end socket and/or lower edge place are provided with the straight flange structure of straight-tube shape, straight flange and the upper flange of its upper end are weldingly connected, and straight flange and the straight tube of lower end are weldingly connected.
Described end socket is ellipsoidal structure.
Voltage transformer tube structure of the present utility model is compared with the conventional cartridge body structure, and the upper and lower side of end socket adopts the straight flange structure of straight-tube shape, and is simple in structure, upper circle and lower circle all leave the convenient welding of straight flange and centering, can improve welding efficiency and rate of finished products, manufacturability is good, the cylindrical shell appearance looks elegant.
Description of drawings
Fig. 1 is traditional voltage transformer tube structure figure;
Fig. 2 is traditional spherical seal head structure chart;
Fig. 3 is the structure chart of the utility model voltage transformer cylindrical shell end socket embodiment;
Fig. 4 is the structure chart of the utility model voltage transformer cylindrical shell embodiment.
Embodiment
Be illustrated in figure 4 as the schematic diagram of the utility model voltage transformer tube structure, as seen from the figure, this cylindrical shell is by upper flange 1, end socket 2, straight tube 3 and lower flange 4 form, and four parts are weldingly connected in turn, the upper end of end socket 2 and/or lower edge place are provided with the straight flange structure of straight-tube shape, straight flange and the upper flange 1 of its upper end are weldingly connected, and the straight flange of lower end and straight tube 3 are weldingly connected, and I, II, III are position while welding among the figure.
As shown in Figure 3, the end socket of the present embodiment adopts ellipsoidal structure, and is simple in structure, and upper circle and lower circle all leave the convenient welding of straight flange and centering, and manufacturability is good, and smooth in appearance is full.
In when welding, at first with end socket 2 and upper flange 1 rivet welding together, and then with straight tube 3 rivet weldings together, lower flange 4 at last is welded, the middle problem that exists is exactly centering, the centering problem between each part, owing to having adopted the end socket with straight flange, this problem just can solve easily.
Tube structure of the present utility model is compared with the conventional cartridge body structure, can improve welding efficiency and rate of finished products, and manufacturability is good, the cylindrical shell appearance looks elegant.
Claims (2)
