a narrow-mouth wine glass tower for a power transmission line comprises a tower head which is in a narrow-mouth wine glass shape and is arranged at the top of a tower body;
the tower head comprises a hollow tower window, a middle cross arm arranged at the top of the tower window, and side cross arms which are arranged at the top of the tower window and extend outwards along two end sides of the middle cross arm; and the top of the side cross arm is respectively provided with a ground wire bracket;
the interfaces of the tower window and the two sides of the middle cross arm are respectively provided with a first suspension string hanging point,
the outer ends of the side cross arms are respectively provided with a second suspension string hanging point,
and third suspension string hanging points are respectively arranged at the top ends of the ground wire brackets.
The first suspension string point suspends a V-shaped wire suspension string of the middle phase wire in series connection.
And the second suspension string hanging point is used for suspending an I-shaped wire suspension string for serially connecting the side phase wires.
And the third suspension string hanging point is used for suspending a ground wire suspension string which is connected with the ground wire in series.
The lower surface of the middle cross arm is arched.
The tower window comprises two symmetrical crank arms,
the bottoms of the crank arms are mutually connected and fixed with the top of the tower body;
the waist of cranking arm is the X type, and widens the cross section at the waist node of X type, forms the ladder type and arranges.
The invention has the advantages that:
according to the power transmission line tower, the crank arms of the traditional wine glass tower are optimized to be in X-shaped arrangement, the nodes are properly opened to a certain width to form ladder-shaped arrangement, the negative end distance of the main material of the crank arms is effectively reduced, the node deformation is reduced, and the safety and reliability of the wine glass tower are improved.
According to the power transmission line tower, the tower-shaped tower head is optimized to be in a narrow wine cup shape, so that the size of the tower head is reduced, the tower weight and the bearing weight of a tower body are reduced, and the width of a line corridor is reduced; the middle phase conductor is inserted into the crank arm for suspension through the V-shaped conductor suspension string, so that the opening width of the tower window can be compressed to the maximum extent; meanwhile, the clearance circles of the middle phase lead and the side phase lead are both attached to the tower head rod piece, the tower head is more compactly arranged, and the corridor width is smaller; the novel transmission line tower effectively overcomes the defects that the existing transmission line tower lead is not compact in arrangement, heavy in tower weight and large in corridor width, has strong practicability and wide applicability, and particularly has good economic and social benefits.
