Abstract
A lower locating device for a transformer body comprises a locating rod (4) arranged on the transformer box bottom (6) and used for locating, an insulating ring (3) arranged in a buckling groove (2) and used for insulation, the buckling groove (2) arranged on a clamping piece (1) and used for fixing the insulating ring (3), and a reinforcing ring (5) arranged on the transformer box bottom (6) and used for reinforcing the locating rod (4). In assembly, the transformer body directly falls down to be automatically guiding and synchronously located, the clamping piece (1) and the oil tank (6) are in a good insulation state, work efficiency is improved, and insulation between the clamping piece (1) and the oil tank (6) is guaranteed.
Description
Technical field
The utility model relates to a kind of transformer body lower part positioning device, is particularly useful for large oil immersed power transformer.
Background technology
Large oil immersed power transformer is drawn separately ground connection by grounding sleeve respectively by transformer core, folder, so that both ground states are carried out to Real-Time Monitoring, simultaneously when transformer manufacture, test, maintenance between the two and the state of insulation of both and fuel tank measure, therefore for transformer body lower part positioning device, be a kind of important transformer part, in existing transformer body lower part positioning device, in transportation, installation, running, be easy to the insulation between folder and fuel tank to cause destruction in various degree.
Summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model is to provide one for transformer body lower part positioning device, has therefore improved operating efficiency, has guaranteed the insulation property between folder and fuel tank.
For achieving the above object, the technical scheme that the utility model is taked is: include on being arranged at the bottom of transformer tank and the backstay playing the role of positioning, be arranged in catching groove and play insulating effect dead ring, be arranged on folder and for the catching groove of fixed insulation ring, be arranged at the bottom of transformer tank on for reinforcing the reinforcing ring of backstay.
On backstay is arranged at the bottom of transformer tank, play the positioning action to transformer body, folder is connected with backstay by dead ring, insulation property good between folder and fuel tank have been guaranteed, owing to having designed catching groove, the folder that is fixed on good dead ring, owing to having designed reinforcing ring, backstay is reinforced at fuel tank, and during assembling, automatically lead and synchronously locate in the direct whereabouts of transformer body, and make folder and fuel tank in good state of insulation.
The utility model has designed, and backstay is provided with reinforcing ring on being set to bullet and being arranged at the bottom of transformer tank between at the bottom of the case of backstay and transformer, is provided with catching groove on folder, is provided with dead ring in catching groove, and backstay is arranged in dead ring.
The utility model has designed, and catching groove is set to have the ring bodies of annular housing.
The utility model has designed, and dead ring is set to the circular body of phenolic aldehyde cloth.
The utility model has designed, and the upper-end part of driving of reinforcing ring is set to be set to connect with transformer tank back welding with the lower end part of backstay welding, reinforcing ring.
Important technology feature and the technique effect of the technical program are: catching groove is buckled in 1 tapping of folder by the high strength phenol aldehyde laminated cloth board dead ring of annular, then catching groove and folder 1 are connect firmly.By be welded at the bottom of transformer tank with the backstay of tapering on, be to improve weld strength, be enclosed within on backstay with reinforcing ring, respectively at backstay and transformer tank back welding, connect.During assembling, automatically lead and synchronously locate in the direct whereabouts of transformer body, and dead ring and locating pin matched in clearance, realized transformer body location, and make folder and fuel tank bottom in good state of insulation.Easy to operate, technique is simple, has improved production efficiency, has guaranteed the operation reliably and with long-term of transformer.
In the technical program, the good insulation between folder and fuel tank is important technical characterictic, in the technical field for transformer body lower part positioning device, has novelty, creativeness and practicality.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Fig. 1 is an embodiment of the present utility model, illustrate by reference to the accompanying drawings the present embodiment, include catching groove 2, dead ring 3, backstay 4 and reinforcing ring 5, at the bottom of backstay 4 is set to bullet and is arranged on transformer tank on 6, at the bottom of backstay 4 and transformer tank, between 6, be provided with reinforcing ring 5, on folder 1, be provided with catching groove 2, catching groove 2 is effectively fixed on folder 1 by dead ring 3, and backstay 4 is arranged in dead ring 3.
In the present embodiment, catching groove 2 is set to have the ring bodies of annular housing.
In the present embodiment, dead ring 3 is set to the circular body of phenolic aldehyde cloth.
In the present embodiment, the upper-end part of driving of reinforcing ring 5 is set to weld with backstay 4, the lower end part of reinforcing ring 5 is set to and 6 welds at the bottom of transformer tank.
Backstay 4 is arranged at the bottom of transformer tank on 6, plays the positioning action to transformer body, folder 1 is connected with backstay 4 by dead ring 3, guaranteed insulation property good between folder 1 and fuel tank 6.
The utlity model has lower feature:
1, owing to having designed catching groove 2, dead ring 3 and backstay 4, backstay 4 is set to bullet, on folder 1, be provided with catching groove 2 by good dead ring 3 folder 1 that is fixed on, during use, backstay 4 is arranged in dead ring 3, plays transformer body location and insulating effect.
2, owing to having designed reinforcing ring 5, reinforced backstay 4.
3, owing to having designed dead ring 3, be looped around on backstay 4, be no longer connecting between metal and metal, insulation effect is good.
In for transformer body lower part positioning device technical field; Every include be arranged at the bottom of transformer tank on 6 and for the backstay 4 that plays the role of positioning, be arranged in catching groove 2 and the technology contents of dead ring 3 that plays insulating effect all in protection range of the present utility model.
