Abstract
A mountainous area anti-swing transmission line tangent tower for glass fiber reinforced plastic V-shaped strings comprises a tower body, a ground wire support, an upper cross arm, a middle cross arm, a lower cross arm and the glass fiber reinforced plastic V-shaped strings. The ground wire support, the upper cross arm, the middle cross arm and the lower cross arm are arranged on the tower body. Each glass fiber reinforced plastic V-shaped string is composed of cylindrical glass fiber reinforced plastic insulating rods, a yoke plate and a suspension clamp. The upper ends of the glass fiber reinforced plastic V-shaped strings are connected with suspension wire hanging plates of the upper cross arm, the middle cross arm and the lower cross arm through Z-shaped hanging plates respectively. According to the mountainous area anti-swing transmission line tangent tower, the pressure resistance and the insulation performance of glass fiber reinforced plastic are combined with the stress features of the V-shaped strings, so that the condition that conventional V-shaped insulator strings are pressed and then fall or are damaged is avoided, windage yaw of wires on a tower head is effectively limited, and the electrical gap distance is guaranteed.
Description
Technical field:
The present invention relates to ultra-high-tension power transmission line technical field, relate in particular to a kind of anti-transmission line of electricity tangent tower that waves in mountain area that adopts glass fiber reinforced plastic V-arrangement string.
Background technology:
In the transmission line of electricity of mountain area, limited by landform, when straight line pole is positioned at lower, vertical span is less than normal, when wind wire, suspension string waves larger, when its angle of oscillation surpasses the design permission angle of oscillation of shaft tower, to cause that live part is inadequate to shaft tower member safe clearance, and existing conventional solution has: 1. adjust shaft tower position; 2. carry additionally weight; 3. reduce the design stress of wire; 4. use instead and allow the larger shaft tower of swing angle; 5. this place's tangent tower is replaced by anchor support; But the main limitation of above scheme is as follows:
1) adjust position, rising tower position, change tower, carry additionally weight and reduce the design stress of wire, can only in less scope, reduce angle of oscillation, DeGrain.
2) tangent tower is replaced by anchor support, can thoroughly solves the gap that angle of oscillation causes inadequate, but can cause construction costs significantly to raise.
Summary of the invention:
The present invention is withstand voltage by glass-reinforced plastic material, insulating properties combine with V-type string loading characteristic, has avoided conventional V-arrangement insulator string pressurized come off or damage, and has effectively limited the windage yaw of wire at tower head place, guarantees electric clearance distance.
In order to solve the problem existing in background technology, the present invention is by the following technical solutions: it comprises tower body, earth wire support, upper cross-arm, middle cross-arm, lower cross-arm, glass fiber reinforced plastic V-arrangement string, on described tower body, be provided with earth wire support, upper cross-arm, middle cross-arm and lower cross-arm, glass fiber reinforced plastic V-arrangement string is comprised of cylindricality glass fibre reinforced plastic insulating rod, yoke plate and suspension clamp, and described glass fiber reinforced plastic V-arrangement string upper end is connected with the thread gripping-board that dangles of upper cross-arm, middle cross-arm, lower cross-arm respectively with Z-type link plate.
Adopt the present invention to compare and have the following advantages with conventional solution:
(1) use glass fiber reinforced plastic V-arrangement string, solved the problem that conventional insulator string can not pressurized.
(2) avoided, because angle of oscillation is excessive, tangent tower is replaced by anchor support, thereby effectively saved investment.
(3) glass fiber reinforced plastic V-arrangement was ganged up Z-type link plate and was connected with cross-arm, can swing along line direction, therefore the present invention is identical with tangent tower on force way.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
The specific embodiment:
With reference to Fig. 1, it comprises tower body 1 the present invention, earth wire support 2 perpendicular to line direction, lower cross-arm 3 perpendicular to line direction, middle phase cross-arm 4, upper phase cross-arm 5 and glass fiber reinforced plastic V-arrangement string 6, on described tower body, be provided with earth wire support, upper cross-arm, middle cross-arm and lower cross-arm, glass fiber reinforced plastic V-arrangement string 6 is by cylindricality glass fibre reinforced plastic insulating rod, yoke plate and suspension clamp form, though conventional bar-shaped composite insulator string and disc insulator string can bearing tensions, but can not pressurized, at shaft tower, be positioned at lower and often can not bear relevant pressure, the present invention adopts glass fiber reinforced plastic V-arrangement string, utilize its insulation characterisitic and can pressurized feature, in addition glass fiber reinforced plastic V-arrangement string upper end with Z-type link plate respectively with upper cross-arm, middle cross-arm, the thread gripping-board that dangles of lower cross-arm connects, make it can be along line direction swing.
The loading condition of shaft tower of the present invention is with basic identical with the tangent tower of condition, be subject to the wind load of horizontal direction, longitudinal load is mainly derived from lead wire and earth wire Longitudinal Wind load, in accident when broken string, is along line direction tension force, stringing tension force during installation, vertical load is from lead wire and earth wire, gold utensil, ice load and shaft tower deadweight, maintainer and instrument gravity.
The scope of application of the present invention is that the conventional tangent tower Kv of 0 < Kv < 0.5(need be greater than 0.5), vertical load direction is downward, adopt glass fiber reinforced plastic V-arrangement string, utilize its compressive property, restriction tower head place wire waves, solved the tower head electric clearance deficiency that the too small angle of wind deflection of shaft tower Kv causes greatly, this tower is with exhaling high angle tower tower material can reduce by 40% left and right.
