Abstract
The utility model discloses an integral expander outer cover for a transformer. A viewing window is arranged on the expander cover body. The integral expander outer cover is characterized in that theintegral expander outer cover is an integral body drawn from a whole piece of plate; open holes protruding towards the periphery and having reinforcing function are arranged at the lower margin of theouter cover, or a semicircular ridge protruding outwards is arranged between the lower part and the lower edge of each open hole; an oil level viewing window protruding outwards and forming a strip vertically is arranged on the integral outer cover and a glass plate is installed on the viewing window; the diameter of the lower edge of the first type of open hole is larger than the diameter of thevertical wall of the cover body, and an arc lead angle is formed at the intersection of the two diameters; the open holes which protrude outwards have reinforcing function and mounting holes are arranged at the lower edges of the open holes; one semicircular ridge protruding outwards is arranged between the lower part and the lower edge of each of the second type and the third type of open holes,and the diameter of each semicircular ridge is larger than the diameter of the vertical wall and the lower edge of the cover body; the circumference of the slightly raised blind end of the third typeof cylindrical shell is smaller than the diameter of the vertical wall; and the circumferential edge of the blind end and the upper edge of the vertical wall are connected through concave pitch arc.The utility model improves the strength of the expander outer cover, and the expander outer cover can not deform, has no wire solder, and is nice-looking in appearance, water-tight, and convenient toinstall and position.
Description
Technical field
The utility model relates to power transformating and supplying facility, instrument transformer integral type expander outer cover.
Background technology
Instrument transformer is the conventional products of widespread usage in power transmission and transformation system with the expander outer cover, and regulation expander outer cover must not have seepage and permanent deformation takes place in the national sector standard " JB/T7068-2002 "; The demonstration of oil level is accurately clear.Expander outer cover on the market is that upper and lower two bodies constitute one by Type of Welding now, and the upper and lower diameter of expander outer cover is the same.Shortcomings such as that such expander outer cover exists is yielding, appearance is not attractive in appearance, bonding wire easy to crackly leaks, installing and locating difference.Yet along with the development of power transmission and transformation industry, instrument transformer is more and more higher with the instructions for use of expander outer cover, and distortion, appearance are not attractive in appearance, bonding wire easy to crackly leaks, installing and locating difference etc. is to need the problem that solves.
Summary of the invention
The purpose of this utility model provides a kind of instrument transformer with integral type expander outer cover, and whole plate made the expander outer cover, and is specious, do not have that bonding wire is water-tight, installing and locating convenient.
A kind of instrument transformer is to be stretched by whole sheet material to form an integral body with integral type expander outer cover, expander outer cover, it is characterized in that cylinder bodily form cover body one end is the cecum of dimpling, and the other end is uncovered, and there is installing hole uncovered lower edge; Have rectangle oil level inspection hole on the cover body wall, to outer lug, inspection hole length is parallel with the cover body height; Glass plate is housed on the inspection hole; Cover degree of lip-rounding shape is different: the uncovered edge diameter of expander outer cover (1) is greater than cover body wall diameter, and two diameter intersection areas are the camber line lead angle, to outer lug uncovered booster action is arranged; The one semicircular ring rib to outer lug is arranged between the uncovered bottom of cover body of expander outer cover (2), the lower edge, and semicircular ring rib diameter is greater than cover body wall and lower edge diameter; The one semicircular ring rib to outer lug is arranged between the uncovered bottom of expander outer cover (3), the lower edge, and cover body cecum circumference is less than the diameter of wall, and the cecum circumferential edges is connected with the recessed camber line of cause on the wall.
The design makes the product of same size under situation about not raising the cost, and has improved the intensity of expander outer cover, specious, can not have distortion, do not have that bonding wire is water-tight, installing and locating is convenient.

Embodiment
The instrument transformer of three kinds of models integral type expander outer cover, it is characterized in that these three kinds of expander outer covers 1 or 2 or 3 all are to be stretched by whole sheet material to form a no seam cover body, on the cover body wall, have rectangle oil level inspection hole 4, to outer lug, inspection hole length is parallel with the cover body height, on the inspection hole 4 glass plate is housed; The cover body of first kind of model expander outer cover 1, see Fig. 1-3: cylinder bodily form cover body one end is the cecum of dimpling, and the other end is uncovered, and there is installing hole uncovered lower edge; Its uncovered edge diameter is greater than cover body wall diameter, and two diameter intersection areas are the arc lead angle, to uncovered booster action of outer lug.
It shown in Fig. 4-6 the expander outer cover 2 of second kind of model, cylinder bodily form cover body one end is the cecum of dimpling, the other end is uncovered, it is characterized in that having between uncovered bottom, the lower edge semicircular ring rib to outer lug, semicircular ring rib diameter is greater than cover body wall diameter, lower edge diameter and wall equal diameters.
It shown in Fig. 7-9 the expander outer cover 3 of the third model, there are a semicircular ring rib to outer lug, lower edge all identical between the uncovered bottom of cylinder bodily form cover body, the lower edge with expander outer cover 2, it is characterized in that the diameter of cylinder bodily form cover body dimpling cecum circumference less than wall, the cecum circumferential edges is connected with the recessed camber line of cause on the wall.
