Abstract
The utility model relates to a transformer assembly, in particular to a transformer insulation end coil. The transformer insulation end coil is characterized by comprising an inner paper tube and an outer paper tube. A plurality of cross-over blocks are arranged between the inner paper tube and the outer paper tube at equal intervals. The cross-over blocks are connected with the inner paper tube and the outer paper tube respectively through insulation rivets. The transformer insulation end coil has the advantages of being simple in structure and safe and reliable, saving cost, improving insulation mechanical strength of a transformer body by using a fixing structure of integral rivet joint, saving insulation cost of the transformer, and improving working efficiency.
Description
(1) technical field
The utility model relates to a kind of transformer device, particularly a kind of insulating end ring of transformer.
(2) background technology
Present stage; The insulating end ring of the power transformer of 220kV and above electric pressure uses paper circle and cross-over block to bond together more, and the bonding reliability of this insulating end ring is not high, and the bonding part is if exist the space; Then increased the possibility of partial discharge of transformer; Because required cross-over block and paper number of turns amount is more, make complicated, the insulation manufacturing cost that has increased power transformer and manufacturing man-hour.
(3) summary of the invention
The utility model is in order to remedy the deficiency of prior art, and a kind of safe and reliable, insulating end ring of transformer of practicing thrift cost is provided.
The utility model is realized through following technical scheme:
A kind of insulating end ring of transformer, its special character is: comprise inner fiber container and outer fiber container, equidistantly be provided with a plurality of cross-over blocks between the inside and outside paper web, cross-over block is connected with outer fiber container with inner fiber container respectively through insulated rivet.
Therefore, the beneficial effect of the utility model is: this insulating end ring of transformer, and simple in structure, safe and reliable, practice thrift cost, adopt the fixed structure of whole riveted joint to strengthen the mechanical strength that the device body insulate, the insulation costs of having practiced thrift transformer has improved operating efficiency.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is the structural representation of the utility model.
Among the figure, 1 outer fiber container, 2 inner fiber containers, 3 cross-over blocks.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.This embodiment comprises inner fiber container 2 and outer fiber container 1, equidistantly is provided with a plurality of cross-over blocks 3 between the inside and outside paper web, and cross-over block 3 is connected with outer fiber container 1 with inner fiber container 2 respectively through insulated rivet.
Adopt the insulating end ring of transformer of the utility model; Substitute the manufacture method that traditional insulating end ring uses paper circle and cross-over block 3 bondings; Reduced the insulating end ring place because bonding exists the space that the possibility of partial discharge takes place, the fixed structure of the whole riveted joint of employing has strengthened the mechanical strength of device body insulation, the insulation costs of having practiced thrift transformer; Improve operating efficiency, be mainly used in the transformer of 220kV and above electric pressure.
Claims (1)
1. insulating end ring of transformer; It is characterized in that: comprise inner fiber container (2) and outer fiber container (1); Equidistantly be provided with a plurality of cross-over blocks (3) between the inside and outside paper web, cross-over block (3) is connected with outer fiber container (1) with inner fiber container (2) respectively through insulated rivet.
