Description
Technical field
The utility model is related to casting technology field, more particularly to a kind of integrally formed Shell of circuit breaker.
Background technology
Pot-type sulfur hexafluoride circuit breaker is the common electrical equipment of power domain.In the prior art, common pot type hexafluoro
The tank body for changing sulphur breaker mostly uses iron plate or aluminium sheet is welded, thus the forming process of tank body is time-consuming and laborious, after molding
The overall dimensions of cylinder body are larger, and the weld seam between each rustproof aluminium sheet weldment of tank body can cut-off generation shadow to breaker
Ring, cause the break performance of breaker to reduce, and even if there is integrally formed sulfur hexafluoride breaker tank body, the tank body casting because
Thickness differs, and thick spot temperature greatly is higher cold really slow, and thin pieces part is cold really fast, cannot really be synchronized because cold, and generation is successively cold really,
At this moment it just will produce shrinkage depression, and the place that the position of feeding generally can be big in wall thickness, thermal center, turning, casting section thickness transition.Therefore
Cause finished product rate in casting process relatively low due to unreasonable in design, stability gradually becomes in During Process of Long-term Operation
Difference causes sulfur hexafluoride gas to leak, and influences the working performance of sulfur hexafluoride breaker.
Invention content
The utility model provides a kind of sulfur hexafluoride breaker tank body of aluminium alloy one cast molding, overcomes because of design
It is not fit and generate casting qualified rate it is low, the disadvantage for the operation stability difference that works long hours.
The utility model uses following technical scheme：A kind of sulfur hexafluoride breaker tank body, including tank ontology, feature exist
Include for the shelly-shaped first part of hemisphere face in the tank ontology, first part's hemisphere face-piece is downwardly extending tubbiness chamber
Body is second part, and the second part is inclined outwardly extensions, forms circular cone face-piece, for Part III, the Part III to
Outer horizontal extension forms Part IV mounting portion；The second part side is provided with round hole, shell surface shape around the round hole
At boss, to increase the mechanical strength around round hole.It is arranged from the boss lower end between the Part IV mounting portion
One section of thickened area, the tank ontology are aluminium alloy one cast molding.
Preferably, the thickened area thickness is 3-6 millimeters.
Preferably, the thickening sector width is 40-60 millimeters.
Preferably, the tank body Part IV mounting portion is equipped with installation screw, facilitates the sulfur hexafluoride breaker
The installation of tank body is fixed.
Preferably, the Part IV mounting portion is the cylindrical cavity of upper and lower opening, the Part IV mounting portion circle
Column cavity internal diameter is less than the second part tubbiness cavity internal diameter, and the Part IV mounting portion cylindrical cavity outer diameter is more than described
At circular cone face-piece largest outside diameter.
It may further be preferable that the Part III circular cone face-piece and the Part IV mounting portion corner part fillet mistake
It crosses.
It may further be preferable that one middle side part outwardly convex of tubbiness cavity described in second part, to increase accommodation space.
Preferably, the Part IV mounting portion is more than the Part III Conical Shells With along the thickness of tank body short transverse
The thickness in face can effectively improve the Mechanical Structure Strength of the tank body.
Advantageous effect
The utility model by increasing the thickened area of certain thickness in the thicker place of wall thickness, local transition corner,
Because thicker in these local wall thickness, when cast molding, cools down slow in casting process, the place of cooled and solidified in the ban
When the liquid metals in the place of postcooling solidification is siphoned away, the shortcomings of middle part is easy to form shrinkage cavity, collapse at this, so as to cause at
Sulfur hexafluoride breaker tank body after type is easy gas leakage or fault location mechanical strength deficiency and leads to structure during the work time
It is destroyed.By the way that thickened area is arranged, when the metal liquid in riser can fill into the thickened area by the Feeding channel, avoid out
It is the shortcomings of showing shrinkage cavity, collapsing, being somebody's turn to do so that sulfur hexafluoride breaker tank body yield rate during cast molding is shown
It writes and improves, the compactness of sulfur hexafluoride breaker tank body part is significantly improved, worked in follow-up sulfur hexafluoride breaker
Cheng Zhong can keep prolonged stability, be not easy to be destroyed, and sulfur hexafluoride gas is not easy to leak.The utility model structure letter
It is single, material is saved, product qualification rate is high during cast molding.
Description of the drawings
Fig. 1 is the front view of a specific embodiment of the utility model.
Fig. 2 is the utility model this specific embodiment B-B direction schematic partial cross-sectional view.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The all other embodiment obtained, shall fall within the protection scope of the present invention.
The utility model provides a kind of sulfur hexafluoride breaker tank body of aluminium alloy one cast molding, overcomes because of design
It is not fit and generate casting qualified rate it is low, the disadvantage for the operation stability difference that works long hours.
The utility model uses following technical scheme：A kind of sulfur hexafluoride breaker tank body, including tank ontology, feature exist
