Abstract
The utility model discloses an outdoor, dry type and three-phase five-limb voltage transformer with 10 KV and consisting of an iron core, a first terminal post (1), a secondary winding (4), high-voltage winding (4) and an insulated protective body (9), wherein the inner iron core is a five-core column structure consisting of three core legs (8) and two bypass iron yokes (2), the insulated protective body (9) is formed adopting the outdoor epoxy resins which is poured by vacuum, the top of the insulated protective body is provided with four first terminal posts (1) formed by pouring of resins and each first terminal post (1) is provided with five to seven parachute small and big skirts. By adopting the structure, the structure of the whole mutual inductor is compact in structure and the electric space is reliable in layout and reliable and stable in performance. The utility model is simple in structure, convenient in assembly, oil free, fully-closed and maintenance free and can be directly arranged at the load center.
Description
The utility model belongs to the middle pressure converting equipment in the electric power system, is the crucial signal transmission equipment of electric power system electric energy metrical and relaying protection.
At present, plain edition oil immersed type voltage transformer is suitable for using indoor and outdoor, and its insulation system mostly is insulating paper and transformer oil compound inslation, and volume is big and heavy, and inflammable, contaminated environment can not be directly installed on load center.Chinese patent ZL98251827.7 discloses a kind of " outdoor type dry-type voltage inductor "; this voltage transformer adopts the insulating protective layer of the outdoor type epoxy resin of moulding by casting as voltage transformer; its bushing surface casting becomes full skirt corrugated; special-purpose closed terminal box is installed at secondary leading-out terminal place; reached miniaturization; no oiling; totally-enclosed; non-maintaining; unattended operation; and can expose the purpose of installation in the open; but this instrument transformer only can insert the single-phase electric wire of 10kV; if insert the three-phase wire of 10kV; then need to install three voltage transformers; both increased the cost of equipment, taken up room again.
The purpose of this utility model is to provide a kind of and can uses out of doors, can insert the voltage transformer of three-phase wire again simultaneously.
In order to achieve the above object, inner iron core of the present utility model adopts three iron core column to add five stem stem formula structures of two other iron yokes, and three groups of coils are set on three iron core column.In order to increase the insulating capacity of coil, the residual voltage winding technique outwards is 0.5 grade of secondary winding, 0.2 grade of secondary winding and high pressure winding by the residual voltage winding on the phenolic aldehyde paper tube successively, and its back panel wiring mode is a star.Whole instrument transformer internal structure is very compact, stable and reliable for performance.
The utility model adopts outdoor type epoxy resin to pour into the insulating protector of voltage transformer under vacuum environment; for volume, the consumption of saving resin that dwindles instrument transformer to greatest extent, the while that reduces production costs make its good looking appearance again; profile of the present utility model is made imitated structure according to the planform of instrument transformer inside secondary winding; 4 primary connection posts are arranged at the top of insulating protector; wherein three primary connection posts are positioned on the half side same straight line in back, and are half side before another primary connection post is positioned at.In order to increase between each binding post and creepage distance over the ground, each primary connection post is all poured into the alternate full skirt of 5-7 layer size, and the cross-sectional area of full skirt is circular, and gamp width a is 1.3-1.5 with the ratio of umbellule width b.
Because the utility model adopts outdoor type epoxy resin to replace plain edition epoxy resin to make insulating protective layer; make voltage transformer have the ability of ultraviolet radiation resisting, weathering resistance erosion; no oiling, fire-retardant, antipollution purpose have been realized, long-time running under can be the out of doors full weather conditions.Because profile of the present utility model is made imitated structure according to the planform of instrument transformer inside secondary winding, thereby has saved the consumption of outdoor type epoxy resin greatly, has dwindled volume, has reduced production cost.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
As depicted in figs. 1 and 2, the iron core of instrument transformer inside is three iron core column 8 and two five stem stem formula structures that other iron yoke 2 is formed, and three groups of coils are set on three iron core column 8.In order to increase the insulation level of coil, residual voltage winding 6 is wound on the phenolic aldehyde paper tube 7, outwards is 5,0.2 grades of secondary winding 4 of 0.5 grade of secondary winding and high pressure winding 3 successively by residual voltage winding 6, and its back panel wiring mode is a star.Adopt this structure can make whole instrument transformer compact conformation, electric space layout is reasonable, and is stable and reliable for performance.Insulating protector 9 adopts outdoor type epoxy resin to pour into a mould under vacuum environment and forms; 4 primary connection posts 1 with the resin-cast moulding are arranged at the top of insulating protector 9; wherein three primary connection posts 1 are positioned on same the half side straight line of back, and another primary connection post 1 is positioned at preceding half side right-hand component.In order to increase between each binding post 1 and creepage distance over the ground, each primary connection post 1 all has 6 layers of full skirt that size is alternate, and the cross-sectional area of full skirt is circular, and gamp width a is 1.4 with the ratio of umbellule width b.The left and right sides of insulating protector 9 is equipped with the secondary connection box 11 of cast aluminium full-closed structure, can effectively prevent entering of rain, snow and dust.The support 10 that the useful channel-section steel in the bottom of insulating protector 9 is made is convenient to install.
