Description
Technical field
The utility model relates to high voltage substation field, relates in particular to a kind of current transformer casing.
Background technology
Commercially available current transformer casing comprises cylindrical shell, main flange, flange seat, main flange welding is fixedly connected on cylindrical shell two ends, flange seat is tubular construction, be welded and fixed and be connected on cylinder body outer wall, this current transformer casing is simple in structure, but tubular flange seat is directly welded and fixed and is connected on cylinder body outer wall, because cylindrical shell wall thickness is thinner, structural rigidity, the intensity of flange seat and cylindrical shell junction are poor, and easily distortion, affects the normal use of current transformer casing.
Summary of the invention
This is practical for the deficiencies in the prior art, designs a kind of structural rigidity, intensity that significantly improves flange seat and cylindrical shell junction, significantly improves the enhancement mode current transformer casing of current transformer casing dependability.
The utility model is achieved through the following technical solutions technical goal.
Enhancement mode current transformer casing, comprises cylindrical shell, main flange I, main flange II, flange seat; Described main flange I, main flange II are welded and fixed and are connected in cylindrical shell two ends; Described flange seat is tubular construction, is welded and fixed and is connected on cylinder body outer wall; Its improvements are: described flange seat and cylinder body outer wall junction are provided with inside flange, and flange seat end face of flange is welded and fixed and is connected on cylinder body outer wall.
In said structure, described main flange I is provided with annular groove, and described cylindrical shell end embeds in annular groove and is welded and fixed connection.
In said structure, described annular groove degree of depth L1 is 0.5～0.8 times of cylindrical shell wall thickness, and inside groove, to centroclinal, forms internal groove with cylinder body outer wall.
In said structure, the tilt angle alpha of described inside groove is 50 °～60 °.
The utility model compared with prior art, has following good effect:
1. flange seat and cylinder body outer wall junction are provided with inside flange, flange seat end face of flange is welded and fixed and is connected on cylinder body outer wall, like this, flange seat flange has certain thickness on the one hand, after cylinder body outer wall is welded and fixed and is connected, significantly improve structural rigidity, the intensity of flange seat and cylindrical shell junction, thereby significantly improve current transformer casing dependability; On the other hand, this structure, the hole of cylinder body outer wall and flange seat flange connections can be less, therefore, also significantly improves structural rigidity, the intensity of flange seat and cylindrical shell junction.
2. main flange I is provided with annular groove, and cylindrical shell end embeds in annular groove and is welded and fixed connection, this syndeton, and ease of assembly, increases work efficiency on the one hand; On the other hand, improve cylindrical shell and main flange I junction structural strength.
3. the inside groove of annular groove, to centroclinal, forms internal groove with cylinder body outer wall, adopts this groove, can make cylindrical shell and main flange I weld more thoroughly, further improves cylindrical shell and main flange I junction structural strength.
