Description
Technical field
The utility model relates to high voltage substation field, relates in particular to a kind of linear pattern isolating switch housing.
Background technology
Existing linear pattern isolating switch shell be take assembly welding formula linear pattern isolating switch shell as main, comprise main cylinder, main drum flange, a cartridge module, cone cylinder, because the main drum flange latus rectum at two ends is less than main cylinder latus rectum, therefore between main cylinder and main drum flange, be provided with cone cylinder, play reducing effect.The large end of cone cylinder is welded and fixed and is connected with main drum flange, small end is welded and fixed and is connected with main drum flange, this linear pattern isolating switch shell mechanism is simple, but there is lower column defects: the one, main cylinder starts reducing with the large end of cone cylinder junction, after welding, be horn structure herein, easily produce larger stress and concentrate; The 2nd, because the diameter in cone cylinder different cross section is different, during manufacture, cone cylinder outside diameter and main cylinder external diameter, cone cylinder end diameter and the basically identical difficulty of main drum flange diameter of bore is larger, manufacturing process difficulty is high, is difficult to guarantee the accuracy of manufacture.
Summary of the invention
This is practical for the deficiencies in the prior art, designs a kind of main cylinder reducing place stress that can significantly reduce and concentrates, and manufacturing process difficulty is low, is easy to guarantee the high accuracy linear pattern isolating switch shell of the accuracy of manufacture.
The utility model is achieved through the following technical solutions technical goal.
High accuracy linear pattern isolating switch shell, comprises main cylinder, main drum flange, a cartridge module; Described cartridge module is comprised of a cylinder, a drum flange, and described cylinder is welded and fixed and is connected with a cylinder for main cylinder side; Its improvements are: also comprise reducing cylinder; Described reducing cylinder is by the whole variable-diameter structure of holding greatly cylindrical tube, cone cylinder, small end cylindrical tube to form successively, and cone cylinder adopts arc transition to be connected with large end cylindrical tube, the small end cylindrical tube at two ends; The large end cylindrical tube of described reducing cylinder is welded and fixed and is connected with main cylinder, and small end cylindrical tube and main drum flange are fixedly welded to connect.
In said structure, described main drum flange is provided with inner stopper; Described main drum flange is linked on reducing cylinder small end cylindrical tube by inner stopper, and is welded and fixed connection.
In said structure, a cylinder junction for described cylinder and main cylinder side is provided with outer groove, internal groove; The depth H 1 of described outer groove is less than the depth H 2 of internal groove.
In said structure, the depth H 2 of described internal groove is greater than 1/2 of a cylinder cylindrical shell wall thickness δ.
The utility model compared with prior art, has following good effect:
1. adopt the reducing cylinder that is provided with large end cylindrical tube, cone cylinder, small end cylindrical tube, the large end cylindrical tube of reducing cylinder is welded and fixed and is connected with main cylinder, like this, main cylinder reducing place is fillet corner structure, significantly reducing main cylinder reducing place stress concentrates, reducing cylinder with main cylinder, being connected of main drum flange be cylindrical tube, control large end cylindrical tube external diameter and main cylinder external diameter, small end cylindrical tube external diameter with less with the basically identical difficulty of main drum flange diameter of bore, manufacturing process difficulty is little, also be convenient to assembling, the accuracy of manufacture is high.
2. main drum flange is provided with inner stopper, and main drum flange is linked on reducing cylinder small end cylindrical tube by inner stopper, and is welded and fixed connection, is easy to like this guarantee the axiality of main drum flange and reducing cylinder, also improves packaging efficiency.
3. a cylinder junction for a cylinder and main cylinder side is provided with outer groove, internal groove, and the depth H 1 of outer groove is less than the depth H 2 of internal groove, and this divided edge structure has increased the cross-direction shrinkage power of weld joint on inner side metal, has avoided the generation of a drum flange eave tile phenomenon.
