Embodiment
Below in conjunction with the accompanying drawings, the specific embodiment of the present invention is described in detail, it is to be understood that of the invention
Protection domain do not limited by embodiment.
As shown in Figure 1 to Figure 2, a kind of lightning-arrest needle tubing pipe of transformer substation framework provided in an embodiment of the present invention mutually passes through T-shaped connection
Flexible Node, including the first pipeline section 10, the second pipeline section 11 and support tube 12, the first pipeline section 10 and the second pipeline section 11 it is perpendicular be in T
Shape structure, support tube 12 are connected to the side that the first pipeline section 10 deviates from the second pipeline section 11, and the node includes mutually passing through plate 20, connecting plate
21 and supporting plate 22, mutually pass through on plate 20 the diameter identical arc-shaped slot offered with the first pipeline section 10, mutually pass through on plate 20 with arc
The adjacent one side of shape notch is connected with the second pipeline section 11, mutually passes through another side adjacent with arc-shaped slot on plate 20 and connecting plate 21
It is connected, the one side of supporting plate 22 is connected on connecting plate 21, another side is connected on support tube 12.
In order to be supplied to connecting plate 21 to provide higher tension, supporting plate 22 is perpendicular to connecting plate 21.
In order to mitigate construction weight, the convenience of welding is improved on the premise of structural strength is ensured, on the second pipeline section 11
Ribs is provided with, the length of intersecting for mutually passing through plate 20 and ribs is 30mm.
As shown in Figure 3-4, Fig. 3 and Fig. 4 is that the T-shaped connection Flexible Node of lightning rod reinforces front and rear Stress Map.
The needle tubing pipe of taking shelter from the thunder of table 1 mutually passes through element stress contrast at different height before and after T-shaped connection Flexible Node is reinforced
Stress after being reinforced it can be seen from table on different height node, which has, significantly to be reduced.
The needle tubing pipe of taking shelter from the thunder of table 2 mutually passes through during T-shaped connection Flexible Node is reinforced when use different intersection length d list at different height
First stress contrast
Intersect length d and take during 30mm at node (near weld seam) element stress than significantly reducing before unguyed, and its
Yield strength of the value much smaller than material；Difference intersects the maximum stress that length phase is passed through at the attachment weld of 20 and second pipeline section of plate 11
It can be reduced in 30mm in secure threshold, when intersecting length and being 40mm, the maximum stress value is slightly decreased, but fall
Less, smaller, to weld during in order to construct convenience is influenceed on structure, takes that to intersect length be 30mm.
A kind of lightning-arrest needle tubing pipe of transformer substation framework mutually passes through the reinforcement means of T-shaped connection Flexible Node, including：
S1, blanking；
S2, it will mutually pass through plate 20 and be soldered on the first pipeline section 10 and the second pipeline section 11；
S3, is welded to connect plate 21, and connecting plate 21 is perpendicular with mutually passing through plate 20；
S4, weld supporting plate 22.
In order that both sides uniform force, prevent because stress causes welding deformation during welding, the two of the first pipeline section 10
Side is provided with the node, mutually passes through plate 20 and uses the symmetrical synchronous welding in both sides.
Disclosed above is only several specific embodiments of the present invention, and still, the embodiment of the present invention is not limited to this, is appointed
What what those skilled in the art can think change should all fall into protection scope of the present invention.
