Description
Technical field
The present invention relates to transmission line of electricity technical field, and in particular to a kind of cable terminal pole.
Background technology
With developing rapidly for current social economy, because overhead transmission line has, floor space is larger, environmental beauty
The inferior position of difference, in the range of city proper, cable run progressively substitutes overhead transmission line, as city ultra-high-tension power transmission line
Main transmission of electricity form.At present, 220kV and above transmission line of electricity are located at suburb more uses overhead power transmission form, positioned at large and medium-sized city
City urban district mainly uses cable power transmission form, and the connecting structure of 220kV overhead transmission lines and cable run is current high voltage power transmission
The weak spot of network, can directly affect city transmission line of electricity normally, stably run, existing 220kV overhead transmission lines and electricity
Cable road connecting structure is commonly cable and angle steel tower connected mode, and this connected mode floor space is big, and construction requirement is high, straight
Connect influence project progress.
Publication No. CN203951149U patent document discloses a kind of 220kV double loops cable terminal pole and corresponding
Transmission system, cable terminal pole includes the long and short two root body of rod, coupling beam, cross-arm, expenditure insulator and cable termination support；Coupling beam
By the connection of the long and short two root body of rod to form double-rod structure, cross-arm includes upper strata, middle level and lower floor's cross-arm, its at the middle and upper levels cross-arm pacify
On the longer body of rod, middle level cross-arm is arranged in the coupling beam of the top, and lower floor's cross-arm is arranged on compared with quarter butt body；Aerial condutor with
Strain insulator-string connection on cross-arm, and jumper connection is supreme draws string, above draws to go here and there and is connected to cable termination by lead, and cable termination is placed on
On cable termination support, every one end of cross-arm is all connected with drawing string on a strain insulator-string and one, because the cable terminal pole is applicable
In connection double loop three-phase aerial condutor, so, upper strata, middle level and lower floor's cross-arm connect six roots of sensation aerial condutor and the six roots of sensation altogether
Lead, six wire is connected with six cable terminations on six groups of cable termination supports respectively, and six cable terminations are respectively with six
Root cable connection, to complete the final conversion of aerial condutor and cable.
Scheme realizes the company of 220kV overhead transmission lines and cable run using cable terminal pole disclosed in above-mentioned patent document
Connect, although reduce floor space than traditional angle steel tower connected mode and reduce difficulty of construction, but in order to avoid short circuit
And break down, three-phase aerial condutor corresponding lead in double loop need to stagger in space, and the three-phase aerial condutor with every time is distinguished
The cross-arm of connection also will be in the different perpendicular in space office, and above-mentioned patent document is by setting two bodies of rod, by even
The long and short two root body of rod is connected into double-rod structure by beam, and upper strata cross-arm is installed on the longer body of rod, is pacified in the coupling beam of the top
Middle level cross-arm is filled, lower floor's cross-arm is installed on the shorter body of rod so that three layers be connected respectively with the three-phase aerial condutor of every time
The cross-arm spatially different perpendicular in office, although this structure can realize three layers of cross-arm, spatially office is different
Perpendicular, but need to set two bodies of rod and connected two bodies of rod with coupling beam, floor space is larger, and constructs not
Convenient, cost is also higher.
The content of the invention
Therefore, the technical problem to be solved in the present invention be to overcome cable terminal pole floor space of the prior art it is big,
The defect that construction is inconvenient, cost is higher, so as to provide, a kind of floor space is small, be easy to construction, lower-cost cable termination
Bar.
