Description
Technical field
The utility model is related to Transmission Line Design fields, and in particular to around strain insulator on the horizontally arranged wire jumper of common-tower double-return
Tower.
Background technology
With the development of transmission line construction, transmission line of electricity is more and more, and scissors crossing is also with regard to more and more, voltage class
Higher, scissors crossing requirement is higher, when boring more voltage levels transmission line of electricity, is typically due to bore the limit for getting over space of points distance
System, causes path length to increase, brill is made to get over difficulty and is greatly improved.Steel tower, which bores more circuit, at present following several ways：
1st, double back line conductor vertical arrangement bores the situation of getting over：Using span is reduced, reduce arc sag, floor height compressed according to span,
For flat mound area circuit, there are reserved passageway to implement for former circuit, can not such as be realized substantially without reserved passageway.
2nd, single loop drilling gets over situation：Using span is reduced, reduce arc sag, wineglass or dry font may be selected as the case may be
Anchor support, but minimum exhales height to be limited by code requirement, and general circuit can be realized, for former line voltage distribution higher grade line
Road is difficult to realize.
3rd, cable drill gets over situation：It bores more place and uses cable mode, this kind brill more mode cost is high, to voltage class than relatively low
Can realize, can not be realized substantially for voltage class is higher.
Patent CN201621117164.3 disclose on a kind of wire jumper around bore get over tower, using support insulator by wire jumper around
Mode, effectively solve conventional jumper and pass through on the downside of the cross-arm, the problem of wire jumper arc sag distance to the ground is insufficient, effectively subtract
Small steel tower exhales title high.When boring more other power circuits, for tower height not by jumper string length limitation, flat mound area is easy to use,
The distance to the ground of consideration span center arc sag minimum point is only needed, without considering further that tower position periphery it is possible that being had an impact to wire jumper
Landform, tower height can be effectively reduced, better met and drilled more the distance between circuit requirement.Existing common-tower double-return
There are mainly two types of forms for line conductor arrangement：Three-phase is arranged vertically and three-phase rounded projections arranged.
By on the single loop wire jumper in patent document CN201621117164.3 around be applied in double circuit line need it is more
Go out three conducting wires, therefore, side cross-arm is subjected to the load of three-phase conducting wire.It is in order to meet above-mentioned requirements that needs increase cross-arm is long
Degree, needs to overcome a series of technical barrier, in the case of being limited in path, needs the spacing between strictly controlling per phase, reaches
To the purpose that can meet the requirement in path corridor but also highly be preferably minimized tower head.The growth of cross-arm will be so that cross-arm and tower
The stability of connection between body becomes particularly important.
