Abstract
The utility model relates to a compound insulation glass reinforced plastic crossarm which is mainly used for solving the problem that the existing compound insulation glass reinforced plastic crossarm in the prior art has low insulation performance. The compound insulation glass reinforced plastic crossarm is characterized in that a wooden internal reinforcement layer (1) is arranged between an upper glass reinforced plastic structural layer (2) and a lower glass reinforced plastic structural layer (3), and the outer parts of the upper glass reinforced plastic structural layer (2) and the lower glass reinforced plastic structural layer (3) are respectively connected with an upper polyurethane paint outer protection layer (4) and a lower polyurethane paint outer protection layer (5). The compound insulation glass reinforced plastic crossarm has high insulation strength, and the arc establishing rate of an insulator and the lighting stroke breaking rate of a circuit can be reduced.
Description
Technical field
The utility model relates to the accessory that uses in a kind of power transmission network, particularly a kind of compound inslation fiberglass cross-arm.
Background technology
In industry security was produced, the component of " " accounted for absolute critical role, and in electric power safety was carried, the dielectric level of power network line was again an important factors.The quality of insulating properties directly influences the use of electric power.Insulating properties are poor, and the probability of sustained arc of insulator and circuit thunderbolt breaking rate are just high.Carbon steel angle steel cross-arm is used in the insulation of power network line usually generally speaking, and a lot of performances of this type cross-arm all have adverse effect in electric power is carried, and the insulating properties of power network line are low.
Summary of the invention
The utility model technical problem to be solved is to overcome the low problem of carbon steel angle steel cross-arm insulating properties that exists in the background technology; And a kind of compound inslation fiberglass cross-arm is provided; This compound inslation fiberglass cross-arm dielectric strength is high, can reduce the probability of sustained arc and the circuit thunderbolt breaking rate of insulator.
The utility model solves its problem and can reach through following technical scheme: this compound inslation fiberglass cross-arm; Comprise top glass steel construction layer and bottom glass steel construction layer, wooden interior enhancement Layer, top polyurethane paint external protection and bottom polyurethane paint external protection; Described top glass steel construction layer and bottom glass steel construction interlayer accompany wooden interior enhancement Layer, and top glass steel construction layer and bottom glass steel construction layer outside are connected to top polyurethane paint external protection and bottom polyurethane paint external protection respectively.
Described top glass steel construction layer and bottom glass steel construction layer and wooden between enhancement Layer, top glass steel construction layer and bottom glass steel construction layer be connected to resin-rich layer respectively and between top polyurethane paint external protection and bottom polyurethane paint external protection.
The utility model and above-mentioned background compared with techniques can have following beneficial effect: this compound inslation fiberglass cross-arm is owing to adopt said structure; The product dielectric strength is high; Have that light weight, high strength, shrinkage factor are low, performance such as good toughness, not easy to crack, mechanical performance height, good anti-corrosion, weatherability are arranged, can increase the dielectric level of power network line preferably; Reduce the probability of sustained arc and the circuit thunderbolt breaking rate of insulator, guarantee the safe operation of power network line.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model.
Among the figure: enhancement Layer in 1-is wooden, 2-top glass steel construction layer, 3-bottom glass steel construction layer, 4-top polyurethane paint external protection, 5-bottom polyurethane paint external protection, 6-resin-rich layer.
The specific embodiment:
To be described further the utility model below in conjunction with accompanying drawing:
Shown in accompanying drawing 1; A kind of compound inslation fiberglass cross-arm; Comprise top glass steel construction layer 2 and bottom glass steel construction layer 3, wooden interior enhancement Layer 1, top polyurethane paint external protection 4 and bottom polyurethane paint external protection 5; Described top glass steel construction layer, 2 and 3 on bottom glass steel construction layer accompany wooden in enhancement Layer 1, top glass steel construction layer 2 and bottom glass steel construction layer 3 outside are connected to top polyurethane paint external protection 4 and bottom polyurethane paint external protection 5 respectively.Described top glass steel construction layer 2 and bottom glass steel construction layer 3 and wooden in 1 of enhancement Layer, top glass steel construction layer 2 and bottom glass steel construction layer 3 respectively and top polyurethane paint external protection 4 and 5 of bottom polyurethane paint external protections be connected to resin-rich layer 6.
The effect of glass fibre reinforced plastic structure layer is to make that section bar has axially, the interior external pressure strength of hoop up and down; The enhancement Layer effect is to make section bar can bear deformation intensity in wooden; The effect of polyurethane paint external protection is corrosion resistant, weather-proof, antiseepage, good, the anti-aging of water conservancy characteristic up and down.
This compound inslation fiberglass cross-arm is to be primary raw material with glass fibre and unsaturated-resin; Be processed into glass fiber reinforced plastic shapes through pultrusion; Section bar is tamped with flitch in the back; Two ends use glass fabric, unsaturated-resin to seal as raw material, hole by instructions for use and the fiberglass sealing of hole is carried out in boring, and are last and other spare and accessory parts are supporting is made.
