Background technology
The existing scheme of currently available technology generally uses a base double loop cable termination tower, the terminal tower to adopt generally using drum Type is arranged, and increases by one layer of auxiliary cross-arm in lower layer conductor cross-arm lower section.In single time overhead transmission line cable T joint draws lower engineering, Using three layer conductor cross-arms suspension wire on the one side of double-loop terminal tower, using wire cross-arm and auxiliary cross-arm suspended cables end End, and by wire jumper by wire around suspension string, arrester and the end junction for causing cable termination, so as to realize trolley line Under road cable T joint draws.
Realize that T connects using double loop strain rod tower, construction cost is higher, column foot floor space is larger, T connects place's wire suspension The perpendicular arrangement of point is different from the arrangement mode of conventional triangular form or upper font, causes adjacent tangent tower wire suspension string to deviate lead Straight state, when electric clearance is unsatisfactory for requiring, need to carry out adjacent tower transformation, so as to construction cost and floor space is significantly increased.
Utility model content
Under overcoming the deficiencies in the prior art, a kind of single time overhead transmission line cable T joint of the utility model offer to draw Anchor support, the single time overhead transmission line cable T joint draws lower anchor support, proposes that single time strain insulator T connects and draws lower scheme, it is only necessary to uses one Base single loop cable T joint anchor support realizes cable T joint, and construction cost is relatively low, and floor space is smaller, and former line arrangement side is not changed Formula, is adapted to neighbouring tangent tower construction, can be used as anchor support.
The utility model solves the technical scheme that is used of above-mentioned technical problem:
A kind of single time overhead transmission line cable T joint draws lower anchor support, including tower body, ground wire cross-arm, upper strata auxiliary cross-arm, Middle layer conductor cross-arm, lower floor aid in cross-arm, cable suspension support, fore-telling font cable to draw lower terminal and support insulator.
The ground wire cross-arm is arranged on the top of tower body, and both sides cross-arm is arranged perpendicular to line direction.
Upper strata auxiliary cross-arm is arranged on the lower section of ground wire cross-arm, and one side cross-arm is arranged perpendicular to line direction, and on The ending of layer auxiliary cross-arm is fixed fore-telling font cable and draws lower terminal and support insulator.The bottom of upper strata cross-arm and tower body connecting place Phase conductor in fixed strain insulator-string suspension.
The middle layer conductor cross-arm is arranged on the lower section that upper strata aids in cross-arm, and both sides cross-arm is arranged in horizontal path direction, in Layer cross-arm ending fixes strain insulator-string Pendent edge phase conductor, and middle layer conductor cross-arm ending is provided with fixed fore-telling font cable and draws lower terminal Cable suspension support.
Lower floor's auxiliary cross-arm is arranged on the lower section of middle layer conductor cross-arm, and both sides cross-arm is arranged in horizontal path direction, under The ending of layer auxiliary cross-arm is provided with the cable suspension support that fixed fore-telling font cable draws lower terminal, and the cable suspension support is set On the both sides cross-arm of lower floor's auxiliary cross-arm.
The fore-telling font cable draws lower terminal and is made up of end, suspension insulator and arrester.
The beneficial effects of the utility model:The single time overhead transmission line cable T joint draws lower anchor support, proposes that single loop is resistance to Open T and connect and draw lower scheme, it is only necessary to cable T joint is realized using a base single loop cable T joint anchor support, construction cost is relatively low, take up an area face Product is smaller, and former line arrangement mode is not changed, is adapted to neighbouring tangent tower construction, can be used as anchor support.
