Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with the accompanying drawings and be embodied as
The present invention is described in detail for example.It should be appreciated that specific embodiment described herein is only in order to explain the present invention, not
For limiting the present invention.
Embodiment 1
As shown in figure 1, a kind of three-phase pipe bus vertical stratification of 500kV transformer station, mainly include A, B, C three-phase pipe mother 1
And pipe mother fixes gold utensil 5, support insulator 2 and support 3, support 3 therein adopts round steel pipe, on support 3 from top to bottom
It is welded and fixed three support members 4 successively, described support member 4 is mutually perpendicular to support 3 respectively, is welded and fixed in support member 4 one end
End bracket 8, passes through bolt 6, nut 7 composition is flexibly connected, with convenient construction again between described end bracket 8 and support insulator 2
During dismounting.
As shown in Figure 2 and Figure 3, the female fixing gold utensil 5 of described pipe is made up of mounting seat 50, lower plate 51 and train wheel bridge 52, upper
Arc groove is respectively provided with clamping plate 52, lower plate 51, and the radius of described arc groove is equal to the radius of pipe mother 1, so that
The female fixing gold utensil 5 of pipe can be fully contacted and the pipe mother 1 being gripped by it between, improves pipe mother by increasing contact area
Stability after 1 fixation.The chute 53 of bar shaped is arranged on described mounting seat 50, described lower plate 51 is run through by connecting pin 54
Chute 53 is movably hinged with mounting seat 50, makes lower plate 51 for linear motion with respect to mounting seat 50 along chute 53;Institute
State and be flexibly connected by bolt 6, nut 7 composition between lower plate 51 and train wheel bridge 52, pipe mother 1 is clamped and fixed in train wheel bridge
52nd, between lower plate 51, easy construction, and also pipe female 1 also has certain freedom of movement after installing, so that pipe mother 1
Certain buffering can be obtained when suffering from the impact of the sharp poundings such as earthquake, to ensure the operation safety of pipe mother 1.
As shown in figure 1, described support insulator 2 is linear structure, its one end passes through bolt 6, nut 7 and end bracket 8
Composition is flexibly connected, and the other end is flexibly connected also by mounting seat 50 composition in bolt 6, nut 7 fixing gold utensil 5 female with pipe,
Therefore, define insulation between support 3 fixing gold utensil 5 female with pipe, pipe mother 1 to be connected.Female 1 point of described A phase, B phase, C phase pipe
Not female with independent pipe fixing gold utensil 5 is connected, and pipe mother's 1 place plane of A phase, B phase, C phase is all mutually perpendicular to level ground,
A phase pipe therein female 1 and the distance between B phase pipe mother 1 L3 are 1.5m-2m, B phase pipe mother 1 and the distance between C phase pipe mother 1 L2
Also it is 1.5m-2m, vertical range L1 between C phase pipe female 1 and level ground is 2.5m-4.5m.Such structure can be effective
Prevent pipe mother 1 because of high-voltage breakdown, to ensure the safe operation of 500kV transformer station;And, described A phase pipe female 1 and B phase pipe mother 1
The distance between L3, B phase pipe female 1 and the distance between C phase pipe mother 1 L2 can be arranged to equal, make the general layout cloth of transformer station
Put more neat, attractive in appearance.
Embodiment 2
As shown in Figure 4, Figure 5, the mounting seat 50 in the female fixing gold utensil 5 of pipe arranges through hole, described lower plate 51 passes through
Connecting pin 54 is run through described through hole and is movably hinged with mounting seat 50, so that lower plate 51 can be with respect to 50 turns of mounting seat
Dynamic, pipe mother 1 so can also be enable to obtain certain buffering when suffering from the impact of the sharp poundings such as earthquake, to ensure pipe mother 1
Operation safety.Other structures are with embodiment 1.
After 500kV transformer station adopts above-mentioned three-phase pipe bus vertical stratification, due to phase between three support insulators 2
Mutually parallel and keep certain spacing so that being also to be parallel to each other and keep certain spacing between pipe mother 1, therefore, it can prevent
