Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further details the present invention:
It is bored the invention discloses a kind of double loop 500kV straight line and gets over tower, be that brill used in power transmission engineering gets over tower, it is outstanding which gets over tower
It is suitable for 500kV double circuit lines.Here is specific embodiment:
The double loop 500kV straight line of the invention, which bores, gets over tower, specifically a kind of electric power pylon comprising tower body 13.The present invention
Mainly the conducting wire suspended portion on 13 top of tower body is improved.It further includes being fixed at 13 top of tower body that the brill, which gets over tower,
Upper cross-arm 1 and lower cross-arm 2.Upper cross-arm 1 and the arrangement setting of about 2 lower cross-arm, and upper cross-arm 1 is located at the most top of tower body 13
End.Common, the distance between upper cross-arm 1 and lower cross-arm 2 are 11.3m, and the suspension for upper conducting wire, lower wire and side conducting wire provides
Safety and sufficient space.
Using the processing that has a down dip at side conducting wire hanging point of the invention, that is, the arm 5 that has a down dip is set.Preferentially, upper cross-arm 1 and the arm that has a down dip
The distance between 5 be 2.6m, that is, the distance that arm 5 extends downwardly in vertical direction that has a down dip is 2.6m, significantly reduces entirety
Tower height.
The present invention is arranged ground wire hanging point 3 at the both ends of upper cross-arm 1 and hangs ground wire 4, also corresponding at upper 1 both ends of cross-arm
The arm 5 that has a down dip is arranged in ground wire hanging point 3.The arm 5 that has a down dip extends obliquely from the end of upper cross-arm 1.Have a down dip arm 5 end setting side
Conducting wire hanging point 6 can reduce the height that the brill gets over tower entirety by 8 Pendent edge conducting wire 7 of insulator chain, the dipping type structure for the arm 5 that has a down dip
Degree.The present invention is arranged upper conducting wire hanging point 9 with 13 intersection of tower body in upper cross-arm 1 and is hung with insulator chain 8, while the arm that will have a down dip
5 are also configured as conducting wire hanging point 9 and are hung with insulator chain 8 with upper 1 intersection of cross-arm.Above-mentioned two insulator chain 8 is symmetrically set
It sets, and upper end connect lower end handover together with two upper conducting wire hanging points 9 and hangs upper conducting wire 10.Upper cross-arm 1 is located at tower body
13 two sides are respectively arranged with one group of insulator chain 8 and hang upper conducting wire 10.Upper conducting wire 10, lower wire 12 and side conducting wire 7 are logical
It crosses insulator chain and bores what more tower was connect with straight line.It is specific as shown in Figure 1.
The present invention is arranged lower wire hanging point 11 at the both ends of lower cross-arm 2 and hangs lower wire 12 by insulator chain 8.This
The brill of invention gets over upper conducting wire, the lower wire of upper conducting wire 10, lower wire 12 and the side conducting wire 7 of tower at rounded projections arranged, under the setting
With side conducting wire under the premise of meeting electrical safety, the height at the top of tower body can reduce, realize that the brill of route is got over.It is specific such as to scheme
1, shown in Fig. 2.
As shown in Figure 1 and Figure 2, upper cross-arm 1 and lower cross-arm 2 are isosceles trapezoidal structure, and further, upper cross-arm 1
Length is greater than the length of lower cross-arm 2.The distance between upper cross-arm 1 and lower cross-arm 2 are 11.3m, which can satisfy conducting wire
Suspension demand and demand for security.
For the present invention in specific implement, the hanging point part as conducting wire is horn structure, i.e., the both ends of upper cross-arm 1
The conducting wire hanging point of the end in portion, the both ends of lower cross-arm 2 and the arm 5 that has a down dip is horn structure.
As shown in Fig. 2, ground wire hanging point can effectively reduce the whole height for boring and getting over tower lower than the top for getting over tower is bored.
The present invention is that double loop straight line bores more tower, and there are two ground wire hanging points for setting to hang ground wire, and there are six conducting wires for setting
Hanging point hangs double back line conductor.By hanging conducting wire, lower wire and side conducting wire rounded projections arranged on every group, from reduction iron
Tower whole height 9.8m.
The present invention realizes the sunk type suspension of side conducting wire, in the case where guaranteeing that ground wire and side conductor spacing are certain, drop
The low height of ground wire, to reduce whole tower height 2.6m.It can satisfy conductor spacing requirement simultaneously and grounded-line cooperation wanted
It asks.
The present invention, which realizes whole tower height, reduces 12.4m, while whole tower steel consumption reduces by 11.2%.
The present invention is a kind of two circuit tangent tower, and the brill for route is got over, and improves the knot of cross-arm and lower cross-arm
Structure and the hanging point for accordingly devising conducting wire are hung by conducting wire, lower wire and side conducting wire rounded projections arranged on every group of conducting wire, with
And the sunk type suspension of side conducting wire, it effectively reduces straight line and bores the tower height for getting over tower, be convenient for passing through for route.
The present invention is that double loop straight line bores more tower, has two groups of conducting wires and two ground wires and at arranged symmetrically.The present invention
In tangent tower the vertical direction pulling force of conducting wire is primarily subjected to when hanging conducting wire, upper conducting wire, lower wire and side conducting wire are set as
Triangle suspension.The suspension setting of conducting wire and ground wire in the present invention, can make the whole stress of tangent tower more rationally balanced, and
And it takes full advantage of straight line and bores the upper space for getting over tower.
Double back line conductor suspension arrangement setting of the invention is reasonable, the brill particularly suitable for 500kV dual loop transmission line
More, it can satisfy 500kV dual loop transmission line and bore electric clearance condition of getting over, guarantee electrical safety；High voltage etc. is avoided simultaneously
The transformation of grade route, with good economic efficiency and social benefit.
