Abstract
A kind of mountain area of glass fiber reinforced plastic V-arrangement string is anti-waves transmission line tangent tower.It comprises tower body, earth wire support, upper cross-arm, middle cross-arm, lower cross-arm, glass fiber reinforced plastic V-arrangement string, described tower body is provided with earth wire support, upper cross-arm, middle cross-arm and lower cross-arm, glass fiber reinforced plastic V-arrangement string is made up of cylindricality glass fibre reinforced plastic insulating rod, yoke plate and suspension clamp, and described glass fiber reinforced plastic V-arrangement string upper end Z-type link plate is connected with the pendency thread gripping-board of upper cross-arm, middle cross-arm, lower cross-arm respectively.The utility model is withstand voltage by glass-reinforced plastic material, insulating properties combine with V-type string loading characteristic, avoids conventional V-arrangement insulator string pressurized and comes off or damage, effectively limit the windage yaw of wire at tower head place, ensures electric clearance distance.
Description
Technical field:
The utility model relates to ultra-high-tension power transmission line technical field, particularly relates to a kind ofly to adopt that the mountain area of glass fiber reinforced plastic V-arrangement string is anti-waves transmission line tangent tower.
Background technology:
In the transmission line of electricity of mountain area, limit by landform, when straight line pole is positioned at lower, vertical span is less than normal, when wind wire, suspension string waves comparatively large, when its angle of oscillation exceedes the design permission angle of oscillation of shaft tower, live part will be caused inadequate to shaft tower component safe clearance, and existing conventional solution have: 1. to adjust shaft tower position; 2. weight is carried additionally; 3. the design stress of wire is reduced; 4. the shaft tower allowing swing angle larger is used instead; 5. this place's tangent tower is replaced by anchor support; But the main limitation of above scheme is as follows:
1) adjust position, raise tower position, change tower, carry additionally the design stress of weight and reduction wire, angle of oscillation can only be reduced in less scope, DeGrain.
2) tangent tower is replaced by anchor support, it is inadequate thoroughly can to solve the gap that angle of oscillation causes, but construction costs can be caused significantly to raise.
Utility model content:
The utility model is withstand voltage by glass-reinforced plastic material, insulating properties combine with V-type string loading characteristic, avoids conventional V-arrangement insulator string pressurized and comes off or damage, effectively limit the windage yaw of wire at tower head place, ensures electric clearance distance.
In order to solve Problems existing in background technology, the utility model 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, described tower body is provided with earth wire support, upper cross-arm, middle cross-arm and lower cross-arm, glass fiber reinforced plastic V-arrangement string is made up of cylindricality glass fibre reinforced plastic insulating rod, yoke plate and suspension clamp, and described glass fiber reinforced plastic V-arrangement string upper end Z-type link plate is connected with the pendency thread gripping-board of upper cross-arm, middle cross-arm, lower cross-arm respectively.
The utility model is adopted to have the following advantages compared with conventional solution:
(1) use glass fiber reinforced plastic V-arrangement string, solving Conventional insulation substring can not the problem of pressurized.
(2) avoid, because angle of oscillation is excessive, tangent tower is replaced by anchor support, thus effective investment reduction.
(3) glass fiber reinforced plastic V-arrangement was ganged up Z-type link plate and was connected with cross-arm, can swing, therefore the utility model was identical with tangent tower on force way along line direction.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
With reference to Fig. 1, the utility model it comprise tower body 1, perpendicular to the earth wire support 2 of line direction, perpendicular to the lower cross-arm 3 of line direction, middle phase cross-arm 4, upper phase cross-arm 5 and glass fiber reinforced plastic V-arrangement string 6, described tower body is 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 composition, though conventional bar-shaped composite insulator string and disc insulator string can bear pulling force, but can not pressurized, be positioned at lower at shaft tower and often can not bear relevant pressure, the utility model 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 Z-type link plate respectively with upper cross-arm, middle cross-arm, the pendency thread gripping-board of lower cross-arm connects, make it can along line direction swing.
The loading condition of the utility model shaft tower is substantially identical with the tangent tower of same condition, be subject to the wind load of horizontal direction, longitudinal load is mainly derived from lead wire and earth wire Longitudinal Wind load, along line direction tension force during accident broken string, stringing tension force during installation, vertical load is conducted oneself with dignity from lead wire and earth wire, gold utensil, ice load and shaft tower, maintainer and instrument gravity.
The utility model scope of application is that 0 < Kv < 0.5(conventional linear tower Kv 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, solve the tower head electric clearance deficiency that the too small angle of wind deflection of shaft tower Kv causes greatly, this tower is comparatively with exhaling high angle tower tower material to reduce about 40%.
