Abstract
The present invention relates to a kind of cabling arrangements of 500kV underground substations, the structure includes multiple cable laying frames and the cable being arranged on cable laying frame, described cable laying frame include a mullion being vertically arranged and with the vertically disposed multiple cross bars being parallel to each other of mullion, one end of each cross bar is hinged by bearing pin and mullion so that cross bar can turn to vertical direction in cable laying frame plane by horizontal direction.Compared with prior art, the present invention has the advantages that to save space, is easily changed, is anti-wear.
Description
Technical field
The present invention relates to underground substation cable laying field, more particularly, to a kind of cable of 500kV underground substations
Laying structure.
Background technology
With developing rapidly for social economy, all trades and professions are all constantly increasing to the demand of electric power, Shanghai Urban center
Area's power load more crypto set.In order to ensure the safe and reliable electricity consumption in downtown area, properly settle such regional land used it is nervous,
The siting of station is difficult, soil is expensive, the costly Construction Problems brought of earth clearance, is integrally required with reference to area planning, is
Land utilization ratio is improved, improves urban landscape, Optimizing City environment, underground substation is arisen at the historic moment.
Due to needing to lay more cable in underground substation and ground is moister, so needing in underground substation
Multiple cable troughs are set to add cable in the position for leaving ground, because existing cable trough is F shape supports, its cross bar can not
Withdraw, thus occupy many spaces, make the originally not abundant underground space narrower, and F shape supports are welding one
Body, it is not easy to remove and changes.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind saving space, it is easy to
Change, the cabling arrangements of antiwear 500kV underground substations.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of cabling arrangements of 500kV underground substations, the structure include multiple cable laying frames and are arranged on
Cable on cable laying frame, described cable laying frame include a mullion being vertically arranged and vertically disposed more with mullion
The individual cross bar being parallel to each other, one end of each cross bar are hinged by bearing pin and mullion so that cross bar can be put down in cable laying frame
Vertical direction is turned to by horizontal direction in face.
Described cross bar section is L-shaped, and its upper surface offers multiple waist-shaped holes side by side, and described cable is arranged on adjacent
Waist-shaped hole between, be fixed on by the band through waist-shaped hole on cross bar.
The spacing of described adjacent, parallel cross bar in the vertical direction is equal, equidistant from top to bottom on described mullion
The bayonet socket being provided for the other end clamping of cross bar.
Described multiple cross bars being parallel to each other alternately are arranged on the both sides of mullion.
It is additionally provided with the upper surface of described cross bar to the cable mounting seat of fixed cable position.
Described mullion is being provided with limited block with cross bar one end hinged place.
Described cable is twisted polyethylene cable.
Compared with prior art, the present invention has advantages below：
First, space is saved, the present invention, which uses, distinguishes the cross bar that alternate and equidistant setting can rotate in mullion both sides,
Left and right is staggered, and is rotated up being allowed to parallel with mullion when being not provided with cable on cross bar being close to, and so reduces
Very big space.
2nd, it is easily changed：The present invention uses the form of hinge, compared to the F shape cable troughs welded before, more just
In replacing and dismounting, and it can also extend, to adapt to more cabling requirements.
3rd, it is anti-wear：The present invention sets the cable mounting seat of plastic cement in the contact position of cable and cross bar, it is therefore prevented that due to adopting
Tightening compressing cable with band causes the situation of friction damage, increases security.
Brief description of the drawings
Fig. 1 is the structural front view of the present invention.
Fig. 2 is the structure left view of the present invention.
Wherein：1st, cable laying frame, 2, cable, 11, mullion, 12, cross bar, 13, cable mounting seat.
Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment：
As illustrated in fig. 1 and 2, the present invention provides a kind of cabling arrangements of 500kV underground substations, and the structure includes more
Individual cable laying frame 1 and the cable 2 being arranged on cable laying frame 1, cable 2 use twisted polyethylene cable, cable laying
Frame 1 include a mullion 11 being vertically arranged and with the vertically disposed multiple cross bars 12 being parallel to each other of mullion 11, each cross bar
12 one end is be hinged by bearing pin and mullion 11 so that cross bar 12 can be rotated in the plane of cable laying frame 1 by horizontal direction
To vertical direction, multiple cross bars 12 being parallel to each other alternately are arranged on the both sides of mullion 11, and adjacent, parallel cross bar 12 is perpendicular
The upward spacing of Nogata is equal, is provided for the card with the other end clamping of cross bar 12 on mullion 11 at equal intervals from top to bottom
Mouthful, mullion 11 is being provided with limited block with one end hinged place of cross bar 12.
The section of cross bar 12 is L-shaped, and its upper surface offers multiple waist-shaped holes side by side, and cable 2 is arranged on adjacent waist-shaped hole
Between, by being fixed on through the band of waist-shaped hole on cross bar 12, it is additionally provided with the upper surface of cross bar 12 to fixed cable position
The cable mounting seat 13 put, it is therefore prevented that cause the situation of friction damage due to tightening compressing cable using band, increase security.
The present invention is not had using the cross bar that alternate and equidistant setting can rotate is distinguished in mullion both sides on cross bar
It is rotated up being allowed to the space be close to, be effectively reduced occupancy parallel with mullion when setting cable.
