Description
Technical Field
The invention relates to the field of high-voltage transmission lines, in particular to a single-loop multipurpose pole tower.
Background
The electric power pole tower has various structures in the high-voltage transmission line, the cross arm of the electric power pole tower is a straight plane cross arm, and the structure basically meets the requirements of a common transmission line wiring method. Along with the improvement of urban planning requirements, the requirements on power transmission line corridors are also more stringent, and the early T joint and the later pi joint of the two power transmission lines are problems to be solved when the existing planning and long-term planning of the power transmission lines are performed.
At present, when a transmission line is newly built, the existing pole tower needs to be modified so as to be capable of being connected in a T mode and in a pi mode. The engineering adopts a high-voltage-class double-loop Zhang Dalai resistance to realize single-loop T connection and pi connection, the structure of the engineering adopts a ground wire, an upper part, a middle part, a lower part and an auxiliary cross arm, and the engineering adopts a double-loop design, so that the size of a tower body and the cross arm is larger, and the number of the cross arms is more; in addition, the double-loop strain tower can only be connected in a T way or a pi way, and if the two ways of connection are changed into the other way, the tower needs to be changed. These problems described above may result in waste of resources.
On the other hand, when the T connection and pi connection of a single loop are realized by adopting the double-loop Zhang Dalai with high voltage level from the technical aspect, the axial force of the pole tower can be increased due to the fact that the jumper wire strings of the pole towers at the two ends of the T grounding point deviate from the suspension point, so that the load of the pole tower is increased, and the safety is poor. Another "cable replacement overhead" solution is poor in economy and many in operation and maintenance failure points due to the large number of cables used.
Therefore, the novel pole tower is designed, so that the pole tower can meet the requirements of early T connection and later pi connection of a power transmission line, and the problem that resource waste is caused can be solved at present.
