Description
Technical field
The utility model relates to a kind of angular transition connection shells, more particularly to one kind is for gas-insulated metal-enclosed
The angular transition connection shell of switchgear (GAS insulated SWITCHGEAR, GIS), belongs to substation equipment technology
Field.
Background technique
Cubicle Gas-Insulated Switchgear (GAS insulated SWITCHGEAR, GIS) is widely used in various shapes
The substation of formula uses mainly as the control of power equipment and transmission line of electricity, protection and measurement in the power system.
Since urban land is more and more nervous and demand of the user to power transformation station arrangement, usually require that GIS product is installed
It can be carried out the conversion of different angle.
Currently, the GIS angles of product conversion connection shell of each voltage class is installed not convenient because structure limits, it is more difficult to
Guarantee product strength, the space of shell both ends connection is very narrow, due to this fault of construction, be easy to cause the connection of shell both ends not
Close or loosening, influences product overall stability.
Summary of the invention
The technical problems to be solved in the utility model is：Provide a kind of structurally reasonable, reliable angle of switching performance turn
Connection shell is changed, the GIS angles of product conversion connection shell installation for solving current each voltage class is inconvenient, shell both ends
The problem of narrow space of connection.
In order to solve the above-mentioned technical problem, there is provided a kind of angular transition connection shells for the technical solution of the utility model
Body, which is characterized in that including middle section sphere, middle section sphere is the spherical structure that both ends are equipped with opening, the both ends point of middle section sphere
Not with upper section flange and lower section flanged joint, bending angle is formed between upper section flange and lower section flange.
Preferably, the upper section flange is to be obliquely installed, and lower section flange is vertically arranged.
Preferably, the angle at the bending angle is 110 °~170 °.
Preferably, the radius of the middle section sphere is 150mm~500mm.
Preferably, the end face of the upper section flange is equipped with multiple first connect by the first bolt with upper body
The end face of through-hole, lower section flange is equipped with multiple the second through-holes connecting by the second bolt with lower case.
Preferably, the wall thickness of the angular transition connection shell is 5mm~30mm.
Preferably, the upper section flange and middle section sphere junction arc transition, middle section sphere and lower section flanged joint
Locate arc transition.
The utility model it is structurally reasonable, by housing design at bending shape, upper body may be implemented and lower case connects
The angular transition and reliable and stable connection connect, bending part and each seamed edge use arc transition, can convert GIS by user's requirement
Angle is connected, user layout demand is met.
Detailed description of the invention
