Abstract
The invention discloses a reinforced high-pressure GIS (gas insulated switchgear) shell. The reinforced high-pressure GIS shell comprises a barrel and flanges at two ends of the barrel. An inner seam allowance is arranged on the end face of one side of an inner hole of each flange; an inner groove is arranged in the orifice of an inner hole at each of two ends of the barrel; the inner seam allowances sleeve the barrel at intervals and are fixedly connected with the same by welding; the depth L1 of each female end is 0.9-1 times of the wall thickness of the barrel; the upper end face of each inner seam allowance is provided with a chamfer 45 degrees to 55 degrees in angle alpha, and the depth L2 of the chamfer is 0.4-0.5 times of the wall thickness of the barrel; the lower end face of each inner seam allowance is provided with another chamfer 35 degrees to 40 degrees in angle beta, and the depth L3 of the chamfer is 0.5-0.7 times of the wall thickness of the barrel; the length L4 of the truncated edge of each inner groove is 0.2 to times of the wall thickness of the barrel; further, gaps are reserved between the end face of the barrel and the lower end faces of the inner seam allowances. The reinforced high-pressure GIS shell is convenient to clean before welding, small in welding stress and welding deformation and small in allowance of secondary machining of the flanges.
Description
Technical field
The present invention relates to high voltage substation field, relate in particular to a kind of GIS housing.
Background technology
High pressure GIS(Gas Insulated Switchgear Cubicle Gas-Insulated Switchgear) housing is the critical component of high-voltage combined electrical apparatus, comprises two end flanges, cylindrical shell; One side end face of flange has the inner stopper matching with cylindrical shell external diameter at endoporus; The both ends of the surface of cylindrical shell are opened internal groove at endoporus; After cylindrical shell and inner stopper assembling, be fixedly welded between two end flanges; Structure was in the past: the deburring of inner stopper upper surface, after cylindrical shell and inner stopper assembling, cannot clear up degree of depth impurity, and when welding, lateral angle weld seam is difficult for merging with weld joint on inner side, cause housing weldquality low, easily produce pore, be mingled with, weld crack and the weld defect such as lack of penetration, affect the result of use of housing, its life-span is had a greatly reduced quality.On the other hand, the groove docking mode of cylindrical shell and flange in the past, lateral angle weld seam is greater than weld joint on inner side, the cross-direction shrinkage amount of lateral angle weld seam is greater than interior weld joint on inner side, cause flange to produce eave tile distortion, in flange, outer face and tubular axis departure are large, need to carry out secondary operations, allowance is bigger than normal, and thickness became uneven after flange processing.
Summary of the invention
This is practical for the deficiencies in the prior art, propose one and can be convenient to preweld cleaning, significantly improve welding quality, significantly reduce and cause flange to produce the welding stress of eave tile distortion simultaneously, reduce the deviation of the interior outer face of flange and axis, reduce the reinforced high pressure GIS housing of the surplus of flange secondary operations.
The present invention is achieved through the following technical solutions technical goal.
Reinforced high pressure GIS housing, comprises the flange at cylindrical shell, two ends; Described flange endoporus is provided with inner stopper in a side end face; The two ends bore orifice of described cylindrical shell is provided with internal groove; Described flange inner stopper gap is sleeved on cylindrical shell, is fixedly connected by welding; Its improvements are: described inner stopper degree of depth L1 is 0.9～1 times of cylindrical shell wall thickness; Described inner stopper upper surface is provided with chamfering, and chamfer angle α is 45 °～55 °, and degree of depth L2 is 0.4～0.5 times of cylindrical shell wall thickness; Described inner stopper lower surface is provided with chamfering, and chamfer angle beta is 35 °～40 °, and degree of depth L3 is 0.5～0.7 times of cylindrical shell wall thickness; Described internal groove root face length L 4 is 0.2～0.3 times of cylindrical shell wall thickness.
In said structure, gap is left in described body end surface and inner stopper lower surface, and this gap L 5 is 0.2～0.3 times of cylindrical shell wall thickness.
The present invention compared with prior art, has following good effect:
1. flange inner stopper upper surface is provided with chamfering, is convenient to clear up groove depth impurity, prevents pore, is mingled with, weld crack and the weld defect such as lack of penetration, significantly improves welding quality.
2. flange inner stopper upper surface is provided with chamfering, this groove docking mode inner side is little with outer side weld difference, can weld cross-direction shrinkage amount in balance medial and lateral, significantly reduce and cause flange to produce the welding stress of eave tile distortion, reduce the deviation of the interior outer face of flange and axis, reduce the surplus of flange secondary operations.
3, gap is left in body end surface and inner stopper lower surface, further reduce groove docking mode inner side and outer side weld difference, further reduce and cause flange to produce the welding stress of eave tile distortion, further reduce the deviation of the interior outer face of flange and axis, further reduce the surplus of flange secondary operations.
