Description

A kind of four return cables cut-off anchor support
Technical field
The utility model is related to ultra-high-tension power transmission line technical field, and especially a kind of four return cable cut-offs anchor support.
Background technology
Existing four times overhead transmission line cables are cut-off in engineering, generally use the return cable terminal tower of two base four, respectively The overhead transmission line of suspension breaking point both sides.Conventional four return cable terminal towers aid in cross-arm to be formed by increasing cable, real Effective fixation of existing cable termination.The shortcoming of the program is to need the newly-built circuit pole tower of two base four to complete to cut-off, and shaft tower builds number Amount is more, and construction cost is higher, and floor space is larger.
Utility model content
A kind of four return cable that the purpose of this utility model is directed to the deficiencies in the prior art and provides cut-offs anchor support.
To achieve these goals, technical solution adopted in the utility model is:
A kind of four return cables cut-off anchor support, including tower body, be provided with tower body top layer ground wire cross-arm, on double back wire Cross-arm, lower double back wire cross-arm and bottom auxiliary cross-arm, the top layer ground wire cross-arm, upper double back wire cross-arm hang down from tower body side Straight to arrange both sides cross-arm in line direction, above-below direction is consistent;The lower double back wire cross-arm, bottom auxiliary cross-arm are in T fonts Arrangement, above-below direction is consistent.
Cable suspension support is respectively connected with each ending of lower double back wire cross-arm, is all connected with each cable suspension support There is fore-telling font cable to draw lower terminal.
The fore-telling font cable draws lower terminal and is made up of end, suspension insulator and arrester, suspension insulator, Arrester is arranged vertically, and arrester is located at suspension insulator top.
Described upper double back wire cross-arm is three-decker, and every layer of cross-arm is from tower body side perpendicular to line direction cloth Both sides cross-arm is put, above-below direction is consistent.
Described lower double back wire cross-arm is three-decker, and every layer of cross-arm arranges that above-below direction is consistent in T fonts.
Every layer of upper double back line conductor cross-arm utilizes both sides cross-arm wire, every layer of lower double back wire cross-arm to be hanged using both sides cross-arm Transmission line of electricity corner outboard wire is hung, every layer using one side cross-arm suspension transmission line of electricity corner inboard wire.
The beneficial effects of the utility model:The tower is applied to overhead transmission line corner, can as 45 degree of the corner number of degrees- 90 degree of angle tower, can be used for four loop unilateral or bilaterals and cut-offs, and preferably adjacent to tangent tower construction, is compared compared with scheme and saved One base shaft tower, reduces construction cost, reduces floor space.

Embodiment
A kind of four return cable as Figure 1-Figure 5 cut-offs anchor support, including tower body 1, top layer ground wire cross-arm 2, upper double Return wire cross-arm 3, lower double back wire cross-arm 4, bottom auxiliary cross-arm 5, cable suspension support 6 and foretell font cable and draw lower terminal 7. The top layer ground wire cross-arm, upper double back wire cross-arm arrange both sides cross-arm, above-below direction from tower body side perpendicular to line direction Unanimously.The lower double back wire cross-arm, bottom auxiliary cross-arm arrange that above-below direction is consistent, adjacent both sides cross-arm angle in T fonts In 90 degree.
The fore-telling font cable draws lower terminal and is made up of end, suspension insulator and arrester, suspension insulator, Arrester is arranged vertically, and arrester is located at suspension insulator top, and end is with arrester at an angle.
(1) when four times overhead transmission line cables cut-off and draw lower angle tower and implement bilateral and cut-off scheme.
The upper double back wire cross-arm, cross-arm leads ground using one side cross-arm suspension transmission line of electricity corner outside on the outside of corner Line, using lead wire and earth wire on the outside of one side cross-arm suspension transmission line of electricity corner, cross-arm is in certain angle with lead wire and earth wire to corner inner side cross-arm Degree.
The lower double back wire cross-arm, bottom auxiliary cross-arm and cable suspension support, in outside suspension transmission line of electricity corner Fixed between the wire cross-arm of side wire, between suspension transmission line of electricity corner outboard wire cross-arm and lower section bottom auxiliary cross-arm Cable termination, fixed position is located at wire cross-arm and bottom auxiliary cross-arm ending, and a cable termination can be fixed between cross-arm.
The lower double back wire cross-arm, middle layer conductor cross-arm, lower layer conductor cross-arm and bottom auxiliary cross-arm, transmit electricity in suspension At circuit corner between the wire cross-arm of inboard wire, suspension transmission line of electricity corner inboard wire cross-arm and lower section bottom auxiliary Cable termination is fixed between cross-arm, fixed position is located at the cable suspension support extended along wire cross-arm and bottom auxiliary cross-arm, And two cable terminations can be fixed between cross-arm.
The wire of wire cross-arm ending is hung on using wire jumper at the fore-telling font cable termination being introduced at below cross-arm, Realize that four times overhead transmission line bilateral cables cut-off.
(2) when the double back overhead transmission line cable cut-offs and draws lower angle tower double loop one side and cut-off scheme.
The lower double back wire cross-arm and bottom auxiliary cross-arm, the wire cross-arm of suspension transmission line of electricity corner inboard wire Between, cable termination fixed between suspension transmission line of electricity corner inboard wire cross-arm and lower section bottom auxiliary cross-arm cancel, Cancel the cross-arm that bottom auxiliary cross-arm 6 is located at below the inboard wire cross-arm of suspension transmission line of electricity corner simultaneously.
The outboard wire of wire cross-arm ending is hung on using wire jumper around the fore-telling font cable termination being introduced at below cross-arm Place;The inboard wire for hanging on wire cross-arm ending is directly connected, so as to realize that the unilateral cable of double back overhead transmission line is opened It is disconnected.
