Description
Technical field
The utility model relates to a kind of transformer core arm-tie, especially a kind of high-power transformer iron-core draw-board structure.
Background technology
High-power transformer generally adopts pulling plate structure.Traditional arm-tie, for guaranteeing enough mechanical strengths and reducing as far as possible perpendicular to arm-tie surface leakage magnetic flux and cause additional eddy current loss, conventionally the steel plate that has several grooves by a monoblock is made, will be by milling groove, weldering two ends stiffener, auger shell pit and hanging axis hole, weldering hanging axis in manufacturing process, processing technology is complicated.
The pulling device of iron core is a crucial operation in iron core assembly, when its unreasonable structure, and operation inconvenience, drawstring assembles up just very difficult, and drawstring tension effect is not good yet, directly affects noise and the performance of iron core, and it is large that noise can become.
Summary of the invention
The purpose of this utility model is just to provide a kind of high-power transformer iron-core draw-board structure, solves problems of the prior art.
The purpose of this utility model is achieved through the following technical solutions: a kind of high-power transformer iron-core draw-board structure, comprise arm-tie, arm-tie connecting plate, arm-tie fixed head, described arm-tie fixed head is welded on transformer body, arm-tie connecting plate with arm-tie fixed head by drawing screw rod and nut to connect, draw between screw rod and arm-tie fixed head and have insulating sleeve, arm-tie comprises two steel bands that separate above, and drawstring welds with the arm-tie connecting plate at two ends respectively.
Further, described arm-tie fixed head is provided with U-lag, and place is also provided with counterbore with U-lag concentric circles, and counterbore radius is greater than U-lag radius, draws screw rod to be loaded on U-lag place, and step radius size and the counterbore radius of described insulating sleeve match.
Further, the degree of depth of described counterbore and the shoulder height of insulating sleeve adapt.
Further, described arm-tie connecting plate and drawstring correspondence position have breach, and drawstring welds with the arm-tie connecting plate at two ends respectively.
The utlity model has following beneficial effect:
The utility model adopt arm-tie connecting plate with arm-tie fixed head by drawing screw rod and nut to connect, between arm-tie, be spaced from each other, when guaranteeing iron core chuck strength, reduce the eddy current loss that vertical leakage flux produces at arm-tie, made arm-tie can adopt general steel plate.
Adopt arm-tie fixed head to be provided with U-lag and counterbore, counterbore radius is greater than U-lag radius, and the step dimension of described insulating sleeve and counterbore radius match, when drawing screw rod to be loaded on U-lag place, the step of insulating sleeve is stuck in counterbore place, can avoid drawing screw rod movement radially.
The utility model is simple in structure, easy to install and use, and effectively stationary transformer drawstring, has avoided transformer pull band to come off, and meets the demand of transformer long-term safety operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation that the utility model is overlooked.
Fig. 3 is the schematic diagram of the utility model arm-tie fixed head.
In figure, arm-tie fixed head 1, arm-tie connecting plate 2, draw screw rod 3, insulating sleeve 4, arm-tie 5, counterbore 6, U-lag 7.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in the figure, a kind of high-power transformer iron-core draw-board structure, comprise arm-tie 5, arm-tie connecting plate 2, arm-tie fixed head 1, described arm-tie fixed head 1 is welded on transformer body, arm-tie connecting plate 2, draws between screw rod 3 and arm-tie fixed head 1 and has insulating sleeve 4 by drawing screw rod 3 and nut to connect with arm-tie fixed head 1, determines the quantity of drawstring according to the size of transformer body, the present embodiment arm-tie 5 comprises three spaced-apart steel bands, and drawstring 5 welds with the arm-tie connecting plate 2 at two ends respectively.
Further, described arm-tie fixed head 1 is provided with U-lag 7, and 7 concentric circles places are also provided with counterbore 6 with U-lag, and counterbore 6 radiuses are greater than U-lag 6 radiuses, draws screw rod to be loaded on U-lag place, and the step radius size of described insulating sleeve 4 and counterbore 6 radiuses match.
Further, the shoulder height of the degree of depth of described counterbore 6 and insulating sleeve 4 adapts.
Further, described arm-tie connecting plate 2 has breach with drawstring 5 correspondence positions, and drawstring 5 welds with the arm-tie connecting plate 2 at two ends respectively.
The present embodiment employing arm-tie connecting plate, is spaced from each other between three arm-ties by drawing screw rod and nut to connect with arm-tie fixed head, when guaranteeing iron core chuck strength, has reduced the eddy current loss that vertical leakage flux produces at arm-tie.Adopt arm-tie fixed head to be provided with U-lag and counterbore, counterbore radius is greater than U-lag radius, and the step dimension of described insulating sleeve and counterbore radius match, when drawing screw rod to be loaded on U-lag place, the step of insulating sleeve is stuck in counterbore place, can avoid drawing screw rod movement radially.
Above-described, be only preferred embodiment of the present utility model, can not limit the scope that this practicality is implemented, every equalization of doing according to the utility model claim changes, and all should still belong in the scope that the utility model contains.
