Embodiment 1

[0034] Such as figure 1 As shown, this embodiment provides a torch-shaped single-circuit large-span power transmission tower, including a tower body 6, a tower leg 7, and an inverted trapezoidal tower window 5 connected to the tower body 6, the height of the tower body 6 and the tower leg Not less than 25m. The inverted trapezoidal insulating tower window 5 has a symmetrical structure, and the first ground wire bracket 1 and the second ground wire bracket 2 are symmetrically fixed on both ends of the top edge 504 of the inverted trapezoidal insulating tower window 5 (the left end and the right end shown in the figure) The first cross arm 3 and the second cross arm 4 are symmetrically fixed to the tops of the two sides (the left side 501 and the right side 503 shown in the figure) of the inverted trapezoidal insulating tower window 5 respectively. The middle part of the top edge 504 of the inverted trapezoidal insulating tower window 5 is provided with an insulating string for...

Abstract

The invention discloses a torch type single loop transmission tower, and belongs to the field of transmission towers. The tower comprises an inverted trapezoidal insulation tower window connected witha tower body. Two ends of the top side of the inverted trapezoidal insulation tower window are respectively connected with a ground wire bracket, and the tops of two sides are respectively connectedwith a side cross arm. The middle of the top side of the inverted trapezoidal insulation tower window is provided with an insulation string. A part of the inverted trapezoidal insulation tower windowlocated in the insulation range formed with the insulation string as the center and the safe electrical range as the radius. Two sides of the inverted trapezoidal insulation tower window adopt a steelmaterial. By designing the tower head into a star shape, the area of the tower window is greatly reduced, and the size and the weight of the tower head are further reduced, so that the tower can be used in the transmission line terrain with relatively soft geology in corridor-restricted area, use of tower material indicators can further be reduced, and the material cost is reduced.

Description

technical field [0001] The invention belongs to the field of high-voltage transmission poles and towers, in particular to a torch type single-circuit transmission poles and towers. Background technique [0002] There are various types of transmission poles and towers used for high-voltage transmission, and there are different types according to transmission circuits, functions, materials, etc. Single-circuit transmission pole tower is one of them, and its representative tower types include wine glass tower and cat head tower. [0003] The conductors of the wine glass tower are arranged horizontally, and are mostly used in medium and heavy ice areas with thicker ice coatings. When it is applied in the ice-covered area, it can avoid the flashover caused by the wire jumping off the ice. The conductors of the cat-head tower are arranged in a triangle, which occupies less corridor resources and is widely used in light ice areas. Taking the conventional 220kV transmission line a...
