Description
Technical field
The present invention relates to high voltage substation field, particularly relate to a kind of linear type disconnecting switch housing.
Background technology
Existing linear type disconnecting switch shell is based on assembly welding formula linear type disconnecting switch shell, including main cylinder, main drum flange, cartridge module, cone cylinder, owing to the main drum flange latus rectum at two ends is less than main cylinder latus rectum, therefore between main cylinder and main drum flange, it is provided with cone cylinder, plays reducing effect.The big end of cone cylinder is welded and fixed with main drum flange and is connected, small end is welded and fixed with main drum flange and is connected, this linear type disconnecting switch shell mechanism is simple, column defects in the presence of but: one is that main cylinder starts reducing with cone cylinder big end junction, it is horn structure after welding herein, easily produces bigger stress and concentrate；Two is owing to the diameter in cone cylinder different cross section is different, and during manufacture, cone cylinder outside diameter is relatively big with the main basically identical difficulty of drum flange diameter of bore with main cylinder external diameter, cone cylinder end diameter, manufacturing process difficulty is high, it is difficult to ensure the accuracy of manufacture；Three is that the insulating properties in shell need to improve.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, design one and can substantially reduce stress concentration at main cylinder reducing, manufacturing process difficulty is low, it is easy to ensure the accuracy of manufacture, the enhancement mode disconnecting switch shell of good insulation preformance.
The present invention is achieved through the following technical solutions technical goal.
Enhancement mode disconnecting switch shell, including 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 with a cylinder for main cylinder side and is connected；It thes improvement is that: also include reducing cylinder；Described reducing cylinder is used arc transition to be connected by the overall variable-diameter structure holding greatly cylindrical tube, cone cylinder, small end cylindrical tube to form successively, cone cylinder with hold greatly cylindrical tube, the small end cylindrical tube at two ends；The big end cylindrical tube of described reducing cylinder is welded and fixed with main cylinder and is connected, and small end cylindrical tube is fixing with main drum flange to be welded to connect；Described main cylinder, reducing cylinder inner wall surface are provided with insulating coating.
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 more than the 1/2 of a cylinder cylinder wall thickness δ.
In said structure, described cylinder inner wall surface also is provided with insulating coating.
The present invention compared with prior art, has the positive effect that:
1. use to be provided with and hold greatly cylindrical tube, cone cylinder, the reducing cylinder of small end cylindrical tube, the big end cylindrical tube of reducing cylinder is welded and fixed with main cylinder and is connected, so, it is fillet corner structure at main cylinder reducing, substantially reduce stress at main cylinder reducing to concentrate, reducing cylinder and main cylinder, the connection of main drum flange are cylindrical tube, control big end cylindrical tube external diameter with main cylinder external diameter, small end cylindrical tube external diameter with less with the main basically identical difficulty of drum flange diameter of bore, manufacturing process difficulty is little, also allowing for assembling, the accuracy of manufacture is high.
The most main cylinder, reducing cylinder inner wall surface are provided with insulating coating, significantly improve the insulating properties of shell.
The most 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 so prone to the axiality ensureing main drum flange with reducing cylinder, also improves packaging efficiency.
4. a cylinder is provided with outer groove, internal groove with a cylinder junction for main cylinder side, the depth H 1 of outer groove is less than the depth H 2 of internal groove, this divided edge structure increases the cross-directional shrink force of weld joint on inner side metal, it is to avoid the generation of a drum flange eave tile phenomenon, also improves the structural strength of the present invention simultaneously.
5. a cylinder inner wall surface also is provided with insulating coating, improves the insulating properties of shell further.
