Abstract
The utility model relates to a kind of novel oil immersed erected current transformer four circle electric installation, primarily of conducting strip, be flexible coupling, pintongs aluminum pipe composition, described pintongs aluminum pipe is " U " shape, by be flexible coupling, the welding of conducting strip, realizing current transformer winding is four circle conductive structures.The utility model is mainly used in an oil immersion just vertical little transformation ratio current transformer core, can realize the designing requirement of small area analysis ratio and high precision current transformer.
Description
(1) technical field
The utility model relates to a kind of little no-load voltage ratio oil immersed erected current transformer four circle electric installations, belongs to high voltage electric equipment field.
(2) background technology
At present; a winding of high-voltage line protection equipment oil immersed erected current transformer is generally two circle structures; when electric current is smaller, class of accuracy is higher; if rated transformation ratio is 2 × 150/5A; class of accuracy is 0.2S level, 5P30 level; rated load is generally 50VA, and when product structure is fixing, the oil immersed erected current transformer of two circle structures is just difficult to meet technical requirement.Therefore, the electric installation that a new winding of research and development is four circles is badly in need of, to meet the needs of high-voltage line protection.
(3) summary of the invention
In order to solve the defect that cannot meet small area analysis ratio, high precision level that existing oil immersed erected current transformer exists, the utility model provides a kind of oil immersed erected current transformer of four circle structures.
The utility model solves the technical scheme that its technical problem adopts:
A kind of novel oil immersed erected current transformer four circle electric installation, primarily of conducting strip, be flexible coupling, pintongs aluminum pipe composition, described dead lobe aluminum pipe overall structure in " U " shape, is made up of pintongs aluminium flake, weld conducting strip between each lobe aluminum pipe, realize four circle conductions; Be flexible coupling by being welded on aluminum pipe after aluminium sheet crimping aluminium strip, as outgoing line device, realizing oil-immersed current transformer winding is four circle conductive structures.
Narrower than " U " shape peristome in the middle part of " U " shape of pintongs aluminum pipe of the present utility model, wider than " U " shape peristome bottom " U " shape; Aluminum pipe ring cross-section divided equally by pintongs aluminium flake.
Conducting strip described in the utility model is aluminium matter conducting strip.
Of the present utility model be flexible coupling by aluminium sheet crimping aluminium strip after be welded, rotatable distortion.
The utility model is mainly used in an oil immersion just vertical little transformation ratio current transformer core, can realize the designing requirement of small area analysis ratio and high precision current transformer.
Beneficial effect:
Former semicircle aluminum pipe is deformed into pintongs aluminum pipe by the utility model, by argon arc welding welding of aluminum matter conducting strip between each lobe aluminum pipe, realizes four circle structures.The oil immersed erected current transformer of this four circle conductive structures can meet small area analysis that existing two circle structures cannot meet than and high-precision technical requirement.The utility model structure is simple, saves a large amount of raw material, can significantly reduce material usage and cost.
(4) accompanying drawing explanation
The structure diagram of Fig. 1, oil immersed erected current transformer four circle electric installation;
Fig. 2, oil immersed erected current transformer four circle electric installation are along the profile in A-A cross section;
In figure, 1 is conducting strip, and 2 is be flexible coupling, and 3 is pintongs aluminum pipes, and 4 is in the middle part of pintongs aluminum pipe, and 5 is bottom pintongs aluminum pipe.
(5) embodiment
Below in conjunction with accompanying drawing, processing assembling of the present utility model is elaborated
In FIG, pintongs aluminum pipe 3 is processed into as shown in Figure 1 " U " type shape.In the middle part of " U " shape, 4 is narrower than " U " shape peristome, and bottom " U " shape, 5 is wider than " U " shape peristome; Aluminum pipe ring cross-section divided equally by pintongs aluminium flake, as shown in Figure 2.By argon arc welding welding of aluminum matter conducting strip 1 and be flexible coupling 2 between each lobe aluminum pipe, realize oil immersed erected current transformer winding four circle electric installation, be flexible coupling 2 by being welded after aluminium sheet crimping aluminium strip, rotatable distortion, realizes oil immersed erected current transformer four circle electric installation distribution.In figure, the effect of each parts is as follows:
Conducting strip 1, as electric connection device, realizes interconnecting between each lobe of pintongs aluminum pipe.
Be flexible coupling 2, as the utility model device outgoing line device;
Pintongs aluminum pipe 3, as the utility model device body.
The beneficial effects of the utility model are, structure is simple, saves a large amount of raw material, can significantly reduce material usage and cost.
Claims (3)
