Abstract

The utility model provides a linear tower in mesh shaped string suspension mode, which is characterized in that two ''U''-shaped string assembled by insulator strings of the upper conductive wire are suspended at the root portion and the end portion of the cross arm of the tower in each loop, two ''V''-shaped string assembled by insulator strings of the lower conductive wire are suspended, and the ''V''-shaped string is attached to the bottom surface of the ''U''-shaped string. No unbalanced force from each portion of the tower is generated from each part of the tower of the utility model, the transferring of force is simple and clear, all the insulator string are pulled, the suspension string can be attached to a three-phase conductive wire after mesh-shaped string suspension, and the requirements to the discharging interval is met at the same time. Compared with the ordinary multi-loop tower, the height is lowered, the number of cross-arms is reduced, so that the weight is effectively decreased, convenience and safety of operation is increased, and the tower is suitable for electricity delivery line in various voltage stages.

Description

A kind of tangent tower of netted extension string mode
Technical field
The utility model belongs to high pressure, superhigh pressure and ultra high voltage power line tower and suspension insulator is hung the string mode field, relates to a kind of tangent tower of netted extension string mode.
Background technology
From the engineering experience of circuit in the past, the extension string of tangent tower pattern generally has following two major types formulas, promptly " I " string and " V " go here and there, each pattern can be by list, duplex is hung on the tower body appropriate location, but satisfy the power-frequency voltage in electric, the lead of operating mode such as switching overvoltage and lightning overvoltage is to the discharging gap requirement of iron tower, and insulator string belongs to flexible cable structure, tension does not allow pressurized only on mechanics, pressurized will cause that insulator is lax to come off or damage, " I " string in the past and " V " are though string can satisfy every requirement of above operating mode, no matter simply connected still is the front and back duplex can only be hung a phase conductor but each " I " string or " V " go here and there, for the multiloop lead, this has just increased the quantity of hanging point, thereby has increased the quantity of iron tower cross-arm.In the power transmission sequence design, iron tower need be resisted the multiple load effect of occurring in nature, ice and snow disaster in the past show various tangent towers the rigidity of line direction generally a little less than, especially under the operating mode that broken by ice, and cross-arm is led owing to being positioned at, the direct application point of ground wire lines tension force, the degree of being damaged is bigger more direct, and the quantity that reduces cross-arm can make iron tower more compact structure, rigidity better.The general multilayer vertical arrangement of common iron tower lead in the multiloop circuit, with the iron tower cross-arm at interval, though vertical arrangement can make the circuit corridor become narrower, this can cause the iron tower overall height higher between each layer, and the iron tower overall height is high more, often iron tower weight is heavy more.For some area to the no requirement (NR) of circuit corridor (as meagrely-populated area or desert region) tower weight index is low more economic advantages are arranged more.
It is not only relevant with the structure of iron tower itself how to compress tower height reduction tower weight under the requirement of satisfying the line-to-ground distance, and how to arrange also relevant with lead.Lead links to each other with iron tower by insulator, and the connected mode that therefore changes insulator just can change the arrangement of lead.
The utility model content
Technical problem to be solved in the utility model is to hang how netted connection and design matching used compact iron tower with it of string, can satisfy the requirement of the various electric pressure power transmission sequences that comprise ultra high voltage.
For solving the problems of the technologies described above, the utility model provides a kind of tangent tower of netted extension string mode, it is characterized in that: the insulator string that hangs two upper conductors in each loop is assembled into " U " type string and is suspended on iron tower cross-arm root and end, two insulator strings that hang lower wire are assembled into " V " type string, connect " V " type string below " U " type string.
Iron tower each several part of the present utility model does not have out-of-balance force under various operating modes, the transmission of power is succinct, distinct, the whole tensions of insulator string, and the extension string after netted connection can connect three-phase conducting wire, satisfies the requirement of electric discharging gap simultaneously.Compare with common multiloop iron tower, reduced tower height, reduced cross-arm quantity, thereby effectively lowered tower weight, increased the convenience and the fail safe of operation, be applicable to the power transmission sequence of various electric pressures.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
With reference to accompanying drawing, the insulator string 2,4 that hangs two upper conductors in each loop is assembled into " U " type string by last connection gold utensil 3 and is suspended on iron tower 1 cross-arm root and end, two insulator strings 5 that hang lower wire are assembled into " V " type string by lower link gold utensil 6, connect " V " type string below " U " type string.
