Abstract
The present utility model provides a double loop single column combined tension tower which is short in jumper wire, small in arc sag, and easy to construct and overhaul. The tower comprises two main towers and an auxiliary tower, the auxiliary tower is arranged between the two main towers, a tension string of the first main tower is connected with a jumper wire string of the auxiliary tower through a jumper wire, and a tension string of the second main tower is connected with the other jumper wire of the auxiliary tower through the jumper wire. In the loop single column combined tension tower, the auxiliary tower is arranged between the two main towers, regardless of the outside or the inside of a corner, the jumper wire is wound and led from the inner corner side, requirements of an electrical gap can be easily satisfied; up and down changing of the jumper wire is realized through utilizing the auxiliary tower fully, line conversion can be realized, the conversion method is concise and clear, and design, construction and operation are all convenience.
Description
Technical field
The utility model relates to a kind of strain tower, especially a kind of double loop single-column combination strain tower.
Background technology
In electric power system, because various factors, the triphase parameter of system is unequal, and this has just caused zero sequence and negative-sequence current.Excessive negative-sequence current will cause motor overheating in the system, at isolated neutral or after zero-sequence current does not surpass certain numerical value in the solidly grounded system, might cause the misoperation of protection.
For double circuit line, because the three-phase conducting wire in same loop arranges vertically in a side that all available space is little, and the requirement of the gap of supertension line is bigger, and strain insulator-string and wire jumper string are longer, and wire jumper is long between string, sag is big, constructional difficulties, and the operating maintenance difficulty is big.
The utility model content
The purpose of the utility model provides the double loop single-column combination strain tower that a kind of wire jumper is short, sag is little, construct easily and overhaul.
Realize a kind of double loop single-column combination strain tower of the utility model purpose; Comprise two king-towers and a secondary tower; Said secondary tower is between two king-towers; Strain insulator-string on first king-tower links to each other with wire jumper string on the secondary tower through wire jumper, and the strain insulator-string on second king-tower passes through wire jumper and links to each other with another wire jumper string on the secondary tower.
The beneficial effect of the utility model is following: a kind of double loop single-column combination strain tower of the utility model, between two king-towers, arrange a secondary tower, no matter still corner is inboard in the corner outside, its wire jumper all from the interior angle side around drawing, the electric clearance requirement that is content with very little; Make full use of the exchange up and down that secondary tower carries out wire jumper, realize the circuit transposition, transposition form is short and sweet, designs, constructs, moves all more convenient.
Description of drawings
Fig. 1 is the structural representation of a kind of double loop of the utility model single-column combination strain tower.
Embodiment
The embodiment of the utility model is following:
As shown in Figure 1; A kind of double loop single-column combination strain tower of the utility model; Comprise two king-towers and a secondary tower 3; Said secondary tower 3 is between two king-towers, and strain insulator-string on first king-tower 15 links to each other with wire jumper string 7 on the secondary tower 3 through wire jumper 6, and the strain insulator-string 5 on second king-tower 2 passes through wire jumper 6 and links to each other with another wire jumper string 7 on the secondary tower 3.
A kind of double loop single-column combination strain tower of the utility model is arranged a secondary tower 3 between two king-towers, no matter still corner is inboard in the corner outside, its wire jumper 6 all from the interior angle side around drawing, the electric clearance requirement that is content with very little; Make full use of the exchange up and down that secondary tower 3 carries out wire jumper 6, realize the circuit transposition, transposition form is short and sweet, designs, constructs, moves all more convenient.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineers and technicians in this area make the utility model technical scheme all should fall in the protection range that claims of the utility model confirm.
