殻からなる短辺側壁15を備え、このタンク本体11に
真空外圧を加えた際における各端7;1(の1動きを1
況明する。Next, the effects of the present invention will be explained. In FIG. 6, the tank body 11 has a flat long side wall 13 and a short side wall 15 made of a partially cylindrical shell, and when a vacuum external pressure is applied to the tank body 11, each end 7; 1
The situation becomes clear.
いま、このタンク本体11に真空外圧P。が作用すると
長辺側!老13部分では端部力PBがタンク内側に働く
。また短辺側壁15となる部分円筒殻では真空外圧P。Now, there is a vacuum external pressure P in this tank body 11. When it acts, the long side! At the 13th section, the end force PB acts on the inside of the tank. Further, in the partial cylindrical shell that forms the short side wall 15, the vacuum external pressure P is applied.

って平坦になろうとする。しかし、この平坦になる力、
すなわち座屈に対して最も影);クシが太きいのは長辺
側壁13と垂直方向の力P2である。When this acts, a force P1 parallel to the long side wall 13 and a force P2 perpendicular to the long side wall 13 move in the 01M portion, and a force P is transmitted as the resultant force. Here, the partial cylindrical shell has a vacuum external pressure P. It tries to become flat by adding . However, this flattening force,
In other words, the comb is thickest due to the force P2 in the direction perpendicular to the long side wall 13.
従ってこの力P2を長辺側壁13の端部力PBとで相殺

大させることができる。Therefore, by canceling out this force P2 with the end force PB of the long side wall 13, the balance between the force P2 of the partial cylindrical shell and the end force PB of the long side wall PB is maintained, and the strength against buckling is increased. and can be stabilized. Therefore, in reality, it is necessary to suppress the force P2 that attempts to flatten the partial cylindrical shell by the end force P of the flat long side wall 13, and by setting P2≦PR, the force P2 This makes it possible to prevent buckling due to oxidation and increase the vacuum resistance, that is, the buckling resistance.

によって、PB以下に減少させることが必要である。Stationary @i Electric appliances For example, in a transformer tank 10, the length of the long side wall 13 in the longitudinal direction is generally determined, and the length of any one of the tank height H (see Figure 5) and tank width W is determined. If so, the dimensions of the entire tank are determined. This is due to electrical constraints due to the transformer capacity, for example, r■-]fiη-shaped winding dimensions and insulation distance. In order to satisfy the above boundary P2≦PB, the long side wall 13
Since the end force PB is given by PB-7LH, the force P perpendicular to the long side plate 13 at the end of the partial cylindrical shell is
2 to below PB by selecting an appropriate radius R and opening angle θ of the cylindrical shell.

。For example, in a tank that adopts a partially cylindrical shell when the length L of the flat long side wall is 2500 mm, P2≦P
In order to satisfy B, the radius R and the opening angle θ must be designed within the range surrounded by the curve L = 2500 mm and the axis of the opening angle θ, taking into account the tank width W. , it is possible to provide a transformer tank with excellent buckling resistance.
