Problems solved by technology

However, the overhanging line insulators generally adopt an "I" string structure. In order to ensure the distance between the wire and the ground, the height of the tower will increase, which will indirectly increase the area occupied by the wineglass tower, and the "I" string structure will produce wires under the action of strong winds. Swing phenomenon, prone to wind flashover

Embodiment 1

[0031] see figure 1 , figure 1 It is a structural schematic diagram of an embodiment of the wineglass tower 100 of the present application. Specifically, the wineglass tower 100 may include a tower head 101 and several sets of composite cross arms 102. In an implementation scenario, the wineglass tower 100 may be provided with two tower arms for the convenience of connecting three-phase conductors, namely figure 1 The tower arm 1011 and the tower arm 1012 are arranged symmetrically in the center. In several groups of composite cross arms 102, at least one end of each group of composite cross arms 102 is connected to the tower head 101, for example, as figure 1 As shown, several groups of composite cross-arms 102 are specifically four groups, including composite cross-arm 1021 , composite cross-arm 1022 , composite cross-arm 1023 , and composite cross-arm 1024 . One end of the composite cross arm 1021 , the composite cross arm 1022 , the composite cross arm 1023 , and the co...

Embodiment 2

[0038] In the implementation manner mentioned in the first embodiment above, as figure 1 As shown, due to the large distance between the tower arm 1011 and the tower arm 1012, generally, it is necessary to adopt the following figure 1 The middle composite cross-arm 1022 and the composite cross-arm 1023 are connected to each other, so as to realize the connection of the middle-phase conductor. In specific implementation, such as Figure 6 As shown, there may also be a small distance between the two tower arms 1111 and the tower arm 1112 in the tower head 1110, so that the connection with the tower arm 1111 and the tower arm 1112 can be realized by using a group of composite cross arms 1122 in the C area . For details, please refer to Figure 6 A structural schematic diagram of another embodiment of the wineglass tower 110 is shown.

[0039] Besides that, with figure 1 Similar to the wineglass tower 100 shown, Figure 6 The wine glass tower 110 in the above is provided wit...

Embodiment 3

[0046] see Figure 8 , Figure 8 It is a structural schematic diagram of an embodiment of the wineglass tower 130 of the present application. and figure 1 The Blackjack Tower 100 shown differs in that Figure 8 Several groups of composite cross-arms 1320 of the wineglass tower 130 do not include composite cable-stayed cross-arms.

[0047] Besides that, with figure 1 The Blackjack Tower 100 in the similar, Figure 8 The wineglass tower 130 in includes a tower head 1310. In an implementation scenario, in order to facilitate the connection of three-phase wires, the wineglass tower 130 can be provided with two tower arms, namely Figure 8 The tower arm 1311 and the tower arm 1312 are arranged symmetrically in the center. In several groups of composite cross arms 1320, at least one end of each group of composite cross arms 1320 is connected to tower head 1310, for example, as Figure 8 As shown, several sets of composite cross-arms 1320 include four sets of composite cross-a...

Abstract

The invention discloses a cup type tower, which comprises a tower head and a plurality of sets of composite cross arms. One or more ends of each set of composite cross arms are connected to the towerhead, at least part of the position, away from the tower head, of each set of composite cross arms is used for hung connection of wires, and the parts, used for hung connection of the wires, of the multiple sets of composite cross arms are located on the same horizontal plane, and thus, it is guaranteed that the wires connected to the cup type tower in a hung mode are arranged on the same horizontal plane. The composite cross arms have the characteristics of high mechanical strength and excellent insulation performance, thus line insulators arranged in an overhung mode can be replaced to achieve the electrical insulation and mechanical connection effects, the wires are in hung connection, and the tower height can be decreased and the floor area can be saved while the same ground clearanceof the wires is guaranteed.

Description

technical field [0001] The present application relates to the technical field of power transmission insulation equipment, in particular to a wine glass tower. Background technique [0002] In the field of power equipment, a wineglass tower is a transmission tower with three-phase wires arranged horizontally and the overall outline of the tower resembles a wineglass. Generally speaking, it is made of metal such as iron, and the connection between the wine glass tower and the wire is connected by a suspension insulator, which plays the role of electrical insulation and mechanical connection between the wire and the wine glass tower. However, the overhanging line insulators generally adopt an "I" string structure. In order to ensure the distance between the wire and the ground, the tower height will increase, which will indirectly increase the area occupied by the wineglass tower, and the "I" string structure will produce wires under the action of strong winds. Swing phenomeno...
