Abstract
The invention discloses a high-precision linear type disconnector shell which comprises a main cylinder, a main cylinder flange, a branch cylinder component and a reducing cylinder. The branch cylinder component comprises an branch cylinder and an branch cylinder flange, wherein the branch cylinder is fixedly connected with the branch cylinder on the lateral side of the main cylinder. The reducing cylinder sequentially comprises a large-end cylindrical cylinder, a conical cylinder and a small-end cylindrical cylinder, wherein the conical cylinder is connected with the large-end cylindrical cylinder and the small-end cylindrical cylinder at two ends in an arc transition manner, the large-end cylindrical cylinder is fixedly connected with the main cylinder through welding, and the small-end cylindrical cylinder is fixedly connected with the main cylinder flange through welding. An inner stop opening is formed in the main cylinder flange. The main cylinder flange sleeves the small-end cylindrical cylinder of the reducing cylinder through the inner stop opening and is fixedly connected with the same through welding. An outer groove and an inner groove are formed in the connection of the branch cylinder and the branch cylinder of the main cylinder. The depth H of the outer groove is smaller the depth H2 of the inner groove. The high-precision linear type disconnector shell is small in structural stress, easy to manufacture and high in manufacturing precision.
Description
Technical field
The present invention relates to high voltage substation field, relate in particular to a kind of linear pattern isolating switch housing.
Background technology
Existing linear pattern isolating switch shell is taking 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, due to the diameter difference in cone cylinder different cross section, will be by larger to 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 when manufacture, manufacturing process difficulty is high, is difficult to ensure the accuracy of manufacture.
Summary of the invention
This is practical for the deficiencies in the prior art, designs one and can significantly reduce main cylinder reducing place stress and concentrate, and manufacturing process difficulty is low, is easy to ensure the high accuracy linear pattern isolating switch shell of the accuracy of manufacture.
The present invention 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 made up 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 overall 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 present invention 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 ensure 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.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the enlarged diagram of II part in Fig. 1.
