Description
Technical field
The present invention relates to a kind of single loop alternate damping conductor spacer of integral type transmission line of electricity suppressing wire ice-shedding, in particular, it is a kind of inter-phase spacer with antivibrator, is arranged between each phase conductor of heavy icing area transmission line of electricity, thus suppressing wire ice-shedding。
Background technology
Electric power energy is the important substance basis of human survival and development, is the favourable guarantee of national economy society 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。
Ultra-high-tension power transmission line is due to features such as housing structure are high, lead wire and earth wire span is big, approach region is wide, and when passing through multiple meteorological condition district, counterweight icing region cannot be dodged completely。Freezing rain and snow disaster weather can cause the serious icing of transmission line of electricity, causes that transmission line of electricity mechanically and electrically performance sharply declines, thus causing the generation of icing density。
The reason causing powerline ice-covering accident has lead wire and earth wire uniformly to wave with uneven icing, wire ice-shedding, lead wire and earth wire broken string and lead wire and earth wire icing。Wherein wire ice-shedding is the one of the main reasons causing transmission line of electricity flashover fault and the accident of falling tower。Wire ice-shedding is the common phenomenon in the transmission line of electricity of ice formation, refers to the icing same period of ice coating wire generation under temperature rising, natural wind effect or vibration percussion or does not come off the same period, thus causing the jumping characteristic of wire to move。Wire ice-shedding can cause conductor spacing to reduce, and causes flashover fault；Insulator chain, gold utensil and steel tower can be produced bigger dynamic impact forces by wire ice-shedding simultaneously, and it is produced destruction。
Summary of the invention
It is an object of the invention to the deficiency overcoming prior art to exist, it is provided that a kind of single alternate damping conductor spacer of back transmission line integral type suppressing wire ice-shedding；The alternate damping conductor spacer of this transmission line of electricity should be able to reduce the Oscillation Amplitude of wire ice-shedding, weaken the bad dynamic effect that gold utensil, shaft tower are produced by wire ice-shedding, effectively prevents from deicing the generation of flashover fault。
It is an object of the invention to complete by following technical solution:
A kind of single alternate damping conductor spacer of back transmission line integral type, it is characterised in that this alternate damping conductor spacer includes the composite insulator that three one end connect one to one respectively and the antivibrator being connected with the other end of three composite insulators with three wires；Silicon rubber umbrella skirt string, the metal wire clamp that one end of composite plug is connected with described wire and two the aluminium alloy grading rings being separately fixed on composite plug and abutting against silicon rubber umbrella skirt string two ends that described composite insulator includes composite plug, string is enclosed within composite plug。
Three armed levers of described antivibrator are radially arranged, the end of each armed lever is connected with a composite insulator。
The axis of three armed levers of described antivibrator is generally aligned in the same plane and intersects at same point and 120 degree of interval between two two axial lines。
Compared with prior art, the invention has the beneficial effects as follows: by installing the inter-phase spacer with antivibrator between transmission line wire, can significantly reduce wire ice-shedding height and wire deices close to distance, effectively prevent from deicing the generation of flashover fault。Alternate damping conductor spacer can also reduce the dynamic impact forces that insulator chain, gold utensil and steel tower are produced by wire ice-shedding, it is prevented that it destroys。Meanwhile, antivibrator can reduce the internal force of inter-phase spacer self during ice-shedding effectively, it is prevented that its fracture。Comparing separate type inter-phase spacer conventional at present, integral type inter-phase spacer has saving material, easy-to-install feature。
The present invention can extensive use in the transmission line of electricity of ice formation。

Detailed description of the invention
Below in conjunction with embodiment shown in the drawings, the present invention is described in further detail。
Alternate damping conductor spacer shown in Fig. 1, including three composite insulators, one end of each composite insulator is connected with wire, and the other end is connected with antivibrator；Three armed levers of this antivibrator are radially arranged, the end of each armed lever connects a composite insulator。Figure shows: alternate 120 degree and be generally aligned in the same plane of the axis of three armed levers of antivibrator, and the axis of each armed lever essentially coincides with the axis of the composite insulator being connected。
In described composite insulator, silicon rubber umbrella skirt string string is enclosed within composite plug；One end of composite plug is attached by metal wire clamp and described wire；Two aluminium alloy grading rings are separately fixed on composite plug and abut against the two ends of silicon rubber umbrella skirt string, thus carrying out spacing to silicon rubber umbrella skirt string。
Principles of the invention is (referring to Fig. 2): three wires are connected into an entirety by the alternate damping conductor spacer of this transmission line of electricity, and wherein during a wire ice-shedding, it can be produced resistance by other two wires, reduces its jump height；Meanwhile, antivibrator can effectively reduce conductor vibration amplitude and inter-phase spacer self internal force, it is prevented that inter-phase spacer self ruptures。
Finally it should be noted that listed above is only present invention specific embodiment in 220kV heavy icing area single loop transmission line of electricity。It is clear that the invention is not restricted to above example, it is also possible to it is applied in other electric pressure heavy icing area transmission lines of electricity。All deformation that those of ordinary skill in the art can directly derive from present disclosure or associate, are all considered as protection scope of the present invention。
