Technical field
Tabula strengthened by the composite material that the utility model relates to a kind of heavy icing area transmission line of electricity wineglass tower; Specifically, be that a kind of composite material that adopts forms stressed tabula face as component, be arranged on heavy icing area transmission line of electricity wineglass tower tower window K Nodes, thus strengthen the component of wineglass tower anti-ice calamity ability.
Background technology
Electric power energy is the important substance basis of human survival and development, is the favourable guarantee of national economy, social sustained and rapid development.Ultra-high-tension power transmission line system is as lifeline engineering important in electrical network, and its safety is directly connected to the realization of power system normal function, is the primary goal of power transmission system design.Freezing rain and snow disaster weather causes the serious icing of transmission line of electricity, cause load significantly to increase, transmission line of electricity machinery and electric property sharply decline, produce that connector damages, tower head distortion, or cause cross-arm to be broken collapsing with shaft tower, even cause the continuous event of falling tower of domino effect.
Wineglass tower, as a kind of single loop transmission line tangent tower type of classics, is widely used in the transmission line of electricity of each electric pressure.Domestic more than 80% heavy icing area transmission line of electricity adopts single circuit design at present, wherein 70% adopts wine glass-shaped tangent tower.The feature of wineglass tower is that its structure belongs to hinged arch model, and upper lower bent lever is connected by K node, operational excellence always under normal design load.But, re-covering under ice condition, the longitudinal force effect that wineglass tower produces owing to suffering the operating modes such as lead wire and earth wire broken string, uneven icing, easily occurring that leading edge deformation, tower body reverse the situation of even tower; Within 08 year simultaneously, ice damage statistics also shows, and the national 500kV transmission line of electricity statistics of falling tower totally 506 bases, single-circuit steel tower accounts for 380 bases, and wherein wineglass tower 183 base, accounts for 48.2% of the single loop sum of falling tower, illustrates that wineglass tower exists certain weak spot under icing overload condition.
From a large amount of Calculation Anaysis for Tunnel Structure result, it is relatively weak that wineglass tower bears uneven ice load ability, particularly under twisting conditions, tower window both sides K node bears as an isolated node moment of torsion that external loads causes, master near this place, tiltedly material all bear larger parasitic moment and shearing action, there is certain structural hidden danger.
Utility model content
The purpose of this utility model is the deficiency overcoming prior art existence, provides a kind of composite material of heavy icing area transmission line of electricity wineglass tower to strengthen tabula; This component should be able to when not affecting electric clearance in wineglass tower tower window, wineglass tower K Nodes improve in twisted planar by force intensity, increase tower window rigidity, effectively to reduce the rod member internal force of K Nodes, improve a glass tower icing overload capacity.
The purpose of this utility model has been come by following technical solution:
Tabula strengthened by the composite material of heavy icing area transmission line of electricity wineglass tower, it is characterized in that: the T-shaped truss that tabula is the tower window bottom being fixed on wineglass tower strengthened by this composite material, and this T-shaped truss is parallel to each other by two and keeps at a certain distance away and forms with the T-shaped frame that some support members are connected as a single entity; The two ends, left and right of described T-shaped truss are fixed on the K node of wineglass tower respectively by connector, and the bottom of described T-shaped truss is fixed on the node of wineglass tower tower window bottom.
The consistency of thickness of the K position of joints of described certain distance and wineglass tower.
Described support member is several X framves connected between two T-shaped framves, or several connecting rods connected between two T-shaped framves.
Described T-shaped frame and support member are connected to form by composite material aggregators by several composite material tubes.
Described connector is be fixed on steel casing joint on T-shaped frame and the attaching nut supporting with steel casing joint.
Compared with prior art, the beneficial effects of the utility model are: this technology makes full use of the insulating properties of composite material, when not affecting electric clearance in wineglass tower tower window, the stressed tabula in a twisted planar is added at wineglass tower K Nodes, former outside of cranking arm internal force that is main, tiltedly material is increased newly tabula material and the main material in inner side of cranking arm is shared, and tower window Path of Force Transfer is more reasonable.Adopt composite material tabula technology strengthened wineglass tower structure to stablize, well solve the problem that ordinary glass tower K node parasitic moment and shearing are concentrated, improve wineglass tower overall structure reliability.Newly-designed wineglass tower is after employing composite material tabula reinforcement technology, and main, oblique material specification of cranking arm all can correspondingly reduce, and overall cost can save about 4%, improves heavy icing area wineglass tower tower head icing overload capacity more than 20% simultaneously.Built wineglass tower is after employing composite material tabula reinforcement technology, and its icing overload capacity improves more than 25%, its anti-ice calamity ability of General Promotion.Can extensive use in newly-designed wineglass tower or built wineglass tower.
