The single-circuit tee-joint transmission tower comprises a tower body, a wire cross arm, a tee-joint auxiliary cross arm, a main line insulator chain and a tee-joint line insulator chain. The wire cross arm and the tee-joint auxiliary cross arm are arranged on the tower body; the tee-joint auxiliary cross arm is arranged below the wire cross arm; the included angle between the tee-joint auxiliary cross arm and the wire cross arm is 90 degrees; the main line insulator chain is arranged on the wire cross arm; and the tee-joint line insulator chain is arranged on the tee-joint auxiliary cross arm. Compared with the common single-circuit tee-joint transmission towers, a main line wire of the novel single-circuit tee-joint transmission tower disclosed by the utility model remains triangular arrangement, suspension strings of adjacent towers at two sides of a tee-joint tower remain vertical, electric clearance of a tower head keeps meeting the original rule design requirements, changing an adjacent tangent tower to a strain tower is avoided, the number of newly-built towers is reduced and the construction cost is saved.
Description
Technical field:
The utility model relates to the ultra-high-tension power transmission line technical field.
Background technology:
Conventional single loop T connects transmission tower and adopts the one-sided cross-arm of double (seeing Fig. 1), and wire adopts vertical arrangement to arrange, its shortcoming is as follows:
(1) the basic routing line wire is converted to vertical arrangement by rounded projections arranged and causes T to connect phase conductor suspension string under the adjacent straight transmission tower of tower both sides to depart from vertical state, cause the tower head electric clearance to diminish;
(2) T connects tower both sides adjacent straight transmission tower and changes anchor support into, needs to remove two tangent towers, and newly-built two anchor supports, increased construction cost greatly.
The utility model content:
It is that the T set up perpendicular to former wire cross-arm direction on the basis of existing single loop anchor support connects auxiliary cross-arm that single loop T of the present utility model connects transmission tower, make the basic routing line wire still adopt rounded projections arranged to arrange, do not need to make adjacent tangent tower into anchor support simultaneously.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises that tower body, wire cross-arm, T connect auxiliary cross-arm, basic routing line insulator string, T link insulator string, be provided with wire cross-arm and T on tower body and connect auxiliary cross-arm, T connects auxiliary cross-arm below the wire cross-arm, T connects auxiliary cross-arm and wire cross-arm angle is 90 degree, be provided with the basic routing line insulator string on the wire cross-arm, T connects on auxiliary cross-arm and is provided with T link insulator string.
The utility model is that the T set up perpendicular to former wire cross-arm direction below existing single loop tension tower conducting wire cross-arm connects auxiliary cross-arm, make the basic routing line wire still adopt rounded projections arranged to arrange, when circuit T connects, the T link " on " wire by wire jumper be connected to basic routing line " on " on the wire wire jumper, the T link " in " wire is connected on basic routing line " left side " wire wire jumper by wire jumper, T link D score wire is connected on basic routing line " right side " wire wire jumper by wire jumper, after T has connect, the basic routing line wire still keeps triangular arrangement, T connects tower both sides adjacent straight transmission tower suspension string and keeps vertical state, solve conventional T and connect the problem that middle adjacent towers tower head electric clearance diminishes, also without changing tangent tower into anchor support, the adjacent straight transmission tower can continue to use, reduced newly-built shaft tower quantity, thereby saved construction cost.
The utility model connects transmission tower with conventional single loop T and compares, make the basic routing line wire still keep triangular arrangement, T connects tower both sides adjacent towers suspension string and keeps vertical state, the tower head electric clearance still keeps former rules designing requirement, avoided changing the adjacent straight transmission tower into anchor support, reduce newly-built shaft tower quantity, saved construction cost.
