Description

A kind of steel tower cross-arm component
Technical field
The present invention relates to steel tower cross-arm field, particularly relate to a kind of steel tower cross-arm component.
Background technology
At present, in electrical power distribution electric system, cross-arm, as supporting member, generally uses in the application.Insulator crossarm is generally provided with silicon rubber cluster parachute or ceramic cluster parachute, thus strengthens creep age distance, improve the dielectric level of cross-arm, and reduce the transmission of electricity corridor of cross-arm.
Current Composite at Abroad shaft tower has 2 kinds of typical structural shapes: one is a kind of cast composite bar that Canadian RS company develops, and is widely used in the overhead wire of Albeta area 10kV and 132kV electric pressure.Two is a kind of 220kV lattice composite material pole towers that San Diego, USA coal gas Utilities Electric Co. (SDGE) and Southern California Edison Co. (SCE) cooperation research and development go out, because shaft tower connecting joint structure is too complicated, die cost is very high, and this lattice transmission tower has only installed 3 base test shaft towers.External use composite material pole tower is mainly considered to reduce transport installation and operation maintenance cost, takes into account and considers to promote line antifouling and lightning protection properties.And China uses composite material pole tower mainly in order to improve dielectric strength, it is applied to the circuit in filthy and lightening activity district strongly.
At present, domestic existing cross-arm skeleton adopts club shaped structure, external surface covering high-temperature sulphurated siliastic, and mechanical strength is low, cannot stand directly on cross-arm and operate during maintenance, otherwise the cluster parachute on cross-arm will be out of shape and damage; In addition, because cross-arm is long-time outdoor use, therefore insect bite and unfirmly closing, also can damage the silicon rubber on cross-arm, thus affect dielectric level and the application life of cross-arm.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of steel tower cross-arm component, has that mechanical strength is high, rigidity is large, be out of shape little, weather, reasonable stress, save the advantage such as material and expense, be applicable to the overhead transmission line of 500kV.
For solving the problems of the technologies described above; the technical scheme that the present invention adopts is: provide a kind of steel tower cross-arm component; comprise: skeleton, the topping covering described skeleton external surface and the cluster parachute be cast in outside described topping; the section configuration of described skeleton is D font; be made up of two orthogonal right-angle sides and a circular arc, described skeleton is formed by connecting by angle steel or plate.
In a preferred embodiment of the present invention, described skeleton is by angle steel or plate is with bolts forms.
In a preferred embodiment of the present invention, described skeleton is that the mode adopting steel sleeve to add flange by angle steel or plate is formed by connecting.
In a preferred embodiment of the present invention, described cluster parachute is cast in the outside of described topping by APG technique.
In a preferred embodiment of the present invention, described topping is outdoor epoxy resin.
The invention has the beneficial effects as follows: adopt D font skeleton; and at skeleton outer side covers topping; cluster parachute is poured into a mould again outside topping; cross-arm component is had, and mechanical strength is high, rigidity is large; be out of shape little, weather, reasonable stress; save the advantage such as material and expense, be applicable to the overhead transmission line of 500kV.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of steel tower cross-arm of the present invention component one preferred embodiment;
Fig. 2 is the sectional schematic diagram of skeleton shown in Fig. 1;
In accompanying drawing, the mark of each parts is as follows: 1, skeleton, and 11, right-angle side, 12, circular arc, 2, topping, 3, cluster parachute.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises:
A kind of steel tower cross-arm component, comprising: skeleton 1, the topping 2 covering described skeleton 1 external surface and the cluster parachute 3 be cast in outside described topping 2.
The section configuration of described skeleton 1 is D font, is made up of, as shown in Figure 2 two orthogonal right-angle sides 11 and a circular arc 12.
The technique that described skeleton 1 adopts pultrusion to add winding makes, and described skeleton 1 is formed by connecting by the angle steel of composite material or plate, and connected mode can be adopt bolt freely to connect, and also can be that the mode adopting steel sleeve to add flange connects.
Described topping 2 pours into a mould the external surface of outdoor epoxy resin at described skeleton 1 for APG technique, or with the external surface of coating surface functional coating at described skeleton 1, for solving the problems such as its surperficial weatherability.
In the present embodiment, described cluster parachute 3 is cast in the outside of described topping by APG technique.The castable of APG has good anti-aging, the performance such as hydrophobicity, corrosion-resistant, anti-bird pest, resistance to electric trace, and can not produce injury to cluster parachute 3 when maintainer walks on cross-arm, is conducive to the operation and maintenance of circuit.Adopt polyurethane foam material as interior insulation in skeleton 1.
APG technique: i.e. epoxide resin automatic pressure gel forming technique (TheAutomaticPressureGelation), is mainly used in and produces mesohigh epoxy insulation goods.Its feature is can by the production cycle of epoxy insulation goods, from traditional vacuum cast needed within tens hours, shorten to tens minutes, and control exothermic effect preferably, be conducive to compensating the contraction caused because of curing reaction, and there is the outstanding advantages such as fabulous dimensional stability and very high mechanical strength.Especially be applied to solid-sealed polar pole used for vacuum circuit breaker, complexity, thin-walled, multi-faceted product of loosing core have more advantage.The outer high-voltage switch gear forward of Present Domestic is non-maintaining, Composite, miniaturization, the high life, high-performance development, adopt APG technology production High-Voltage Insulation goods more to demonstrate outstanding technical advantage and vast potential for future development.
Present invention is disclosed a kind of steel tower cross-arm component; adopt D font skeleton; and at skeleton outer side covers topping; outside topping, pour into a mould cluster parachute again, cross-arm component is had, and mechanical strength is high, rigidity large, is out of shape little; weather; reasonable stress, saves the advantage such as material and expense, is applicable to the overhead transmission line of 500kV.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize manual of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
