Abstract
The utility model discloses a kind of small capacity transformer dedicated built-in cannula C T bushing lifting seat,It includes cannula C T,Raise cylinder,Binding post,Insulating end ring,Supporting plate,Transformer box cover,Sleeve pipe mounting flange,Supporting plate passes through bolt and Stud connection,Cannula C T is pressed in rise cylinder,The transformer box cover of described rise cylinder inner ring is provided with mounting hole and capping,Raise barrel,Sleeve pipe mounting flange and transformer box cover are being directly welded to connect,Eliminate original case lid mounting flange,Raise the welding process and installation process of drum flange,The case lid for welding the bushing lifting seat is overturn when cannula C T is assembled,Cannula C T,Insulating end ring,Supporting plate etc. is arranged on inside case lid rise seat on request,It is excessive to not only solve conventional flange connection rise seat occupancy case lid area,The problem of cumbersome and easy oil leakage,Because space not enough must not be not added with high fuel tank when solving the problems, such as to install CT built in sleeve pipe again.With many merits such as flexibility is high, production cost is small.
Description
Technical field
Technical field of transformer equipment is the utility model is related to, specially a kind of small capacity transformer dedicated built-in cannula C T
Rise seat.
Background technology
Domestic small-sized oil-filled transformer at present, as protection and measuring current transformer（CT）All it is mounted in height
Press in cabinet, sometimes according to design requirement, cannula C T is needed on the body of transformer, the tradition that the country generally uses now
Mounting means be：Upper and lower rise seat mounting flange is first welded, then sleeve pipe CT and upper mounting flange are installed, then welded and installed
The method that the mode that the rise seat of flange is connected with connects, because the capacity of transformer is small, installing space is limited, behaviour
It is inconvenient to make, and transformer built-in cannula C T uses traditional bushing lifting seat, can only by increase the method for oil tank of transformer come
Realize, complex procedures, manufacture and cost of transportation can be considerably increased；Meanwhile raise what is be also easy to produce when seat and fuel tank bolt connection
Oil leak, sealing gasket fatal problem easy to aging.
The content of the invention
To solve the above problems, the utility model provides a kind of special rise seat for including built-in cannula C T, structure
Reasonable in design, convenient and flexible installation, good airproof performance.
For achieving the above object, technical solution adopted in the utility model is：
A kind of small capacity transformer dedicated built-in cannula C T rise seat, it include cannula C T, rise cylinder, binding post,
Insulating end ring, supporting plate, transformer box cover, sleeve pipe mounting flange, rise cylinder are cylindrical shape, and upper end open is consolidated with sleeve pipe mounting flange
Connect and seal calmly, lower end is fixedly connected with transformer box cover, sleeve pipe mounting flange inner face be fixedly connected with three it is uniform
Stud, cannula C T upper ends contact connection with sleeve pipe mounting flange medial surface, and cannula C T lower ends contact connection with supporting plate upper surface, support
Plate sets insulating end ring by bolt and Stud connection between cannula C T, the transformer box cover of described rise cylinder inner ring is set
There are mounting hole and capping, the diameter of mounting hole is less than rise cylinder diameter, more than supporting plate diameter, lidstock mounting hole.
Further, cylinder and sleeve pipe mounting flange is raised to weld, rise cylinder and transformer box cover be being directly welded to connect into
Type, stud weld with sleeve pipe mounting flange, and the sealing means of capping and mounting hole are welding.
When cannula C T is assembled, sleeve pipe mounting flange elder generation welding screw, then sleeve pipe mounting flange and rise cylinder are welded into
Type, then raise cylinder and welded with transformer box cover, case lid is overturn, successively on request pacified cannula C T, insulating end ring, supporting plate etc.
Inside case lid rise seat, eliminate and relied on flange and bolted process originally, save layout limited on case lid
Space.
The beneficial effects of the utility model are：Compared to original rise barrel structure, this product effectively solves low capacity change
Depressor space layout is limited and is difficult to install the problem of sleeve pipe CT raises seat；It it also avoid simultaneously because rise seat and fuel tank bolt
The oil leak that is also easy to produce during connection, sealing gasket fatal problem easy to aging, have it is simple in construction, occupy little space, be easy to operate, be close
Seal the characteristics of effect is good.
Brief description of the drawings
Fig. 1 is the utility model embodiment structural representation；
Fig. 2 is Fig. 1 overlooking the structure diagram.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
A kind of small capacity transformer dedicated built-in cannula C T rise seat as shown in drawings, it includes cannula C T1, rise cylinder
2nd, binding post 3, insulating end ring 4, supporting plate 5, transformer box cover 6, sleeve pipe mounting flange 7, rise cylinder 2 is cylindrical shape, and upper end is opened
Mouth is fixedly connected and sealed with sleeve pipe mounting flange 7, and lower end is fixedly connected with transformer box cover 6, the inner face of sleeve pipe mounting flange 7
It is fixedly connected with three uniform studs 8, cannula C T1 upper ends contact connection with sleeve pipe mounting flange medial surface, under cannula C T1
End contacts connection with the upper surface of supporting plate 5, and supporting plate 5 is connected by bolt with stud 8, and insulating end ring 4 is set between cannula C T, described
The transformer box cover 6 of rise cylinder inner ring be provided with mounting hole and capping 9, the diameter of mounting hole is less than the rise diameter of cylinder 2, is more than
The diameter of supporting plate 5, the sealing mounting hole of capping 9.
Further, rise cylinder 2 welds with sleeve pipe mounting flange 7, and rise cylinder 2 connects with transformer box cover 6 for directly welding
Type is connected into, stud 8 welds with sleeve pipe mounting flange 7, and the sealing means of capping 9 and mounting hole are welding.
The part for needing to install cannula C T additional on transformer box cover 6 first carries out out mounting hole, and sleeve pipe mounting flange 7 welds
The stud 8 of three installation supporting plates, the sleeve pipe mounting flange 7 of cylinder 2, welding screw then will be raised according to certain design orientation
（Such as：The cooperation direction of gas port, direction of binding post etc.）It is directly welded at case lid mounting hole, and inside and outside full weld, prevent
Seepage, when cannula C T1 is assembled, the transformer box cover 6 for first soldering sleeve being raised seat is overturn, successively on request by sleeve pipe insulating end
Circle 4, cannula C T1, supporting plate 5 are arranged on inside case lid rise cylinder 2, and are fixed cannula C T1 by supporting plate 5 and nut, prevent from covering
Pipe CT is in transport shift.
Described above is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of technical field
For personnel, on the premise of the utility model principle is not departed from, some improvement can also be made, wound is not being paid in these improvement
The scope of protection of the utility model is also should be regarded as under the premise of the property made work.
