Abstract
The utility model discloses a kind of coil insulation structure of open type three-dimensional wound core dry type transformer, described coil comprises multiple line cake by wire coiling, described line cake is wrapped with the square ring of tape insulation paint, and described square ring is bondd on online cake by insulating varnish.The utility model adopts the square ring with insulating varnish to replace insulating paper, and wrap up line cake, square ring and line cake are bonded together by insulating varnish, without the need to again through paint-dipping process process, saves technological process, effectively enhances productivity.Square ring with insulating varnish also makes mutually to bond between wire and between line cake and fixture, and Stability Analysis of Structures is firm, guarantees that power equipment meets the requirements of electric property, mechanical performance and insulation property.
Description
Technical field
The utility model relates to field transformer, especially a kind of coil insulation structure of open type three-dimensional wound core dry type transformer.
Background technology
At present, traditional open-type transformer coil insulation structure, after wire coiling completes, bag multilayer insulation paper is added to whole line cake, then also need to carry out drying and dipping lacquer process, to ensure moisture resistance and the electric property of coil, the operation that conventional coil insulation system makes is loaded down with trivial details, required time is long, efficiency is low, increases production cost.
Utility model content
The technical problem that conventional coil insulated structure technique is complicated in order to solve, Production Time is long, the utility model provides a kind of coil insulation structure of open type three-dimensional wound core dry type transformer, the manufacture craft of this coil insulation structure is simple, greatly enhances productivity.
To achieve these goals, the technical scheme that the utility model adopts is:
A coil insulation structure for open type three-dimensional wound core dry type transformer, described coil comprises multiple line cake by wire coiling, and described line cake is wrapped with the square ring of tape insulation paint, and described square ring is bondd on online cake by insulating varnish.
Further, described square ring comprises the upper bottom of arc, and connects the outer side edges of upper bottom, and the upper bottom of square ring and outer side edges, effectively insulate from three in the face of line cake wraps up.
Further, each line cake is wrapped with multiple square ring.
The beneficial effects of the utility model:
The utility model adopts the square ring with insulating varnish to replace insulating paper, and wrap up line cake, square ring and line cake are bonded together by insulating varnish, without the need to again through paint-dipping process process, saves technological process, effectively enhances productivity.Square ring with insulating varnish also makes mutually to bond between wire and between line cake and fixture, and Stability Analysis of Structures is firm, guarantees that power equipment meets the requirements of electric property, mechanical performance and insulation property.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Fig. 1 is the coil schematic diagram of the utility model insulation system;
Fig. 2 is the square ring schematic diagram of the utility model insulation system.
Embodiment
See figures.1.and.2, the coil insulation structure of a kind of open type three-dimensional wound core dry type transformer that the utility model provides, described coil 1 comprises multiple line cake 2 by wire coiling, each line cake 2 is wrapped with the square ring 3 of multiple tape insulation paint, square ring 3 comprises the upper bottom of arc, and connecting the outer side edges of upper bottom, the upper bottom of square ring 3 and outer side edges, and to be bondd on online cake 2 by insulating varnish from three in the face of line cake wraps up.
The utility model adopts the square ring 3 with insulating varnish to replace insulating paper, and wrap up line cake 2, square ring 3 and line cake 2 are bonded together by insulating varnish, without the need to again through paint-dipping process process, saves technological process, effectively enhances productivity.Square ring 3 with insulating varnish also makes mutually to bond between wire and between line cake 2 and fixture, and Stability Analysis of Structures is firm, guarantees that power equipment meets the requirements of electric property, mechanical performance and insulation property.
The above, just preferred embodiment of the present utility model, the utility model is not limited to the structure of above-mentioned execution mode, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection range of the present utility model.
