Abstract
The utility model discloses a positioning device between an upper oil reservoir and a transformer body of a large-size transformer, which can avoid the phenomenon of screw bolt looseness of the transformer body caused by transportation. The utility model has the main structure that the upper side of an iron core is fixedly provided with a positioning bowl; the inner wall of the upper oil reservoir is fixedly provided with a positioning pin corresponding to the positioning bowl; a resin layer is arranged between the positioning pin and the positioning bowl. When the positioning device is used, no loosening phenomenon of a screw bolt of the transformer body in the process of transportation occurs and the use performance of the transformer can be ensured.
Description
Technical field
The utility model relates to the last fuel-economizing case of high-power transformer and the positioner between the device body.
Background technology
The device body of high-power transformer mainly is made of unshakable in one's determination and coil windings, and iron core is formed by bolted by silicon steel sheet usually.At present, high-power transformer---as the structure of last fuel-economizing case in the 110KV high-power transformer and the positioner between the device body as shown in Figure 1, its structure is mainly: be set with location square iron bowl 4 at 5 upsides unshakable in one's determination, last fuel-economizing case 2 is provided with and square iron bowl 4 corresponding flange holes, the special cover plate pin of making 1 is arranged in the flange hole, the bottom of cover plate pin 1 and last fuel-economizing case 2 fix, and cover plate pin 1 extend in the square iron bowl 4 and plays positioning action.Always there is the gap owing to make between cover plate pin 1 and the square iron bowl 4, so paperboard strip 3 jam-packs can filled up usually between square iron bowl 1 and the cover plate pin 4.The shortcoming of the positioner of said structure is: paperboard strip 3 can deliquescing after stressed in transportation, make the gap between cover plate pin 1 and the square iron bowl 4 increasing, thereby cause oil tank of transformer and last fuel-economizing case vibration aggravation, the vibration of device body is and then aggravation also, the final fastening bolt of iron core that makes itself becomes flexible, and has influence on the service behaviour of transformer.Therefore, after high-power transformer transports the user place to, the user takes out the oil in the fuel tank always earlier, with last fuel-economizing case sling, with the displacement situation of the loosening situation of checking fastening bolt unshakable in one's determination and device body, and in addition fastening and revise, to go up the fuel-economizing case at last again and install and pour into insulating oil, so not only very bother, and be easy to generate oil seepage phenomena.
Summary of the invention
At the problems referred to above, the utility model will provide a kind of last fuel-economizing case of the high-power transformer that device body bolt produces loosening phenomenon and positioner between the device body of can not making.
The concrete technical scheme that the utility model adopts is: the last fuel-economizing case of described high-power transformer and the positioner between the device body, its structure is mainly: be set with the location bowl at upside unshakable in one's determination, be characterized in: on the inwall of last fuel-economizing case, be set with and locate the corresponding alignment pin of bowl, between alignment pin and location bowl, also be provided with resin bed.
The further technical scheme of the utility model is: also be provided with between location bowl and resin bed and separate the dixie cup layer.
The utility model has the advantages that: in high-power transformer, use described positioner, in transportation device body bolt with regard to impossible loosening phenomenon, convenient for users to use widely, also guaranteed the serviceability of transformer.
Description of drawings
Fig. 1 is the structural representation of positioner between last fuel-economizing case described in the background technology and the device body;
Fig. 2 is a structural representation of going up positioner between fuel-economizing case and the device body described in the utility model.
Execution mode
Below in conjunction with the drawings and specific embodiments technical scheme described in the utility model and advantage thereof are further described.
As shown in Figure 2, it is a preferred embodiment of going up positioner between fuel-economizing case and the device body described in the utility model, its structure is mainly: be set with location bowl 4 at 5 upsides unshakable in one's determination, on the inwall of last fuel-economizing case 1, be set with and locate bowl 4 corresponding alignment pins 6, between alignment pin 6 and location bowl 4, also be provided with resin bed 3.In the present embodiment, between location bowl 4 and resin bed 3, also be provided with and separate dixie cup layer 2.Because resin has stress deformation, characteristic that will spontaneous curing through about ten hours under field conditions (factors), and certain viscosity, therefore, after being provided with resin bed 3 between alignment pin 6 and the location bowl 4, even through long-distance transport, alignment pin 6 still can be fixed together tightly with location bowl 4, and can not produce gap and loosening phenomenon, so just alleviated the vibration of device body effectively, device body fastening bolt just can not produce loosening phenomenon yet, the user checks again with regard to not needing, greatly facilitate user's use, also further guaranteed the service behaviour of transformer.It is to be convenient to alignment pin 6 be separated with location bowl 4 that the purpose of separating dixie cup layer 2 is set.
Claims (2)
1, the last fuel-economizing case of high-power transformer and the positioner between the device body, its structure is mainly: be set with the location bowl at upside unshakable in one's determination, it is characterized in that: on the inwall of last fuel-economizing case, be set with and locate the corresponding alignment pin of bowl, between alignment pin and location bowl, also be provided with resin bed.
2, positioner as claimed in claim 1 is characterized in that: also be provided with between location bowl and resin bed and separate the dixie cup layer.
