Technical scheme is: a single time alternate damping conductor spacer of transmission line integral type which this alternate damping conductor spacer of characterized in that includes composite insulator that three one end is connected with three wire one -to -ones respectively and the attenuator of being connected with three composite insulator's the other end, composite insulator include silicon rubber full skirt cluster on the combined material plug of combined material plug, cluster cover, with the one end of combined material plug with metal fastener that the wire is connected and two fix respectively on the combined material plug and support the aluminum alloy equalizer ring that butts silicon rubber full skirt cluster both ends.
Description
Technical field
The utility model relates to a kind of single loop integral type transmission line of electricity suppressing wire ice-shedding alternate
Damping conductor spacer, in particular, is the inter-phase spacer of a kind of band antivibrator, is arranged on heavy icing area transmission of electricity
Between each phase conductor of circuit, thus suppress wire ice-shedding.
Background technology
Electric power energy is the important substance basis of human survival and development, is that national economy society is sent out continuously and healthily
The favourable guarantee of exhibition.Ultra-high-tension power transmission line system is as lifeline engineering important in electrical network, and its safety is straight
Connect the realization being related to power system normal function, be the primary goal of power transmission system design.
Ultra-high-tension power transmission line, due to features such as housing structure are high, lead wire and earth wire span is big, approach region is wide, is being worn
During the most 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 transmission line of electricity mechanically and electrically performance drastically to decline, thus causes icing thing
Therefore generation.
The reason causing powerline ice-covering accident have lead wire and earth wire uniformly with uneven icing, wire ice-shedding,
Lead wire and earth wire broken string and lead wire and earth wire icing are waved.Wherein wire ice-shedding is to cause transmission line of electricity flashover fault
The one of the main reasons of the accident of falling tower.Wire ice-shedding is the common phenomenon in the transmission line of electricity of ice formation, is
Refer to ice coating wire raise at temperature, icing same period of producing under natural wind effect or vibration percussion or not same period
Come off, thus cause the jumping characteristic of wire to move.Wire ice-shedding can cause conductor spacing to reduce, and causes
Flashover fault；Wire ice-shedding can produce bigger dynamic impulsion to insulator chain, gold utensil and steel tower simultaneously
Power, produces destruction to it.
Utility model content
The purpose of this utility model is the deficiency overcoming prior art to exist, it is provided that a kind of suppression wire deices
The single alternate damping conductor spacer of back transmission line integral type jumped；The alternate damping conductor spacer of this transmission line of electricity should be able to
Reduce the Oscillation Amplitude of wire ice-shedding, gold utensil, the bad of shaft tower generation are moved by weakening wire ice-shedding
Stress effect, effectively prevents from deicing the generation of flashover fault.
The purpose of this utility model completes 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
The composite insulator that connects one to one with three of the wires respectively including three one end and with three compound inslations
The antivibrator that the other end of son connects；Described composite insulator includes that composite plug, string are enclosed within compound
Silicon rubber umbrella skirt string on material plug, the metal wire that one end of composite plug is connected with described wire
Folder and two aluminium alloys being separately fixed on composite plug and abut against silicon rubber umbrella skirt string two ends
Grading ring.
Three armed levers of described antivibrator are radially arranged, the end of each armed lever and a composite insulator
Connect.
The axis of three armed levers of described antivibrator is generally aligned in the same plane and intersects at same point, and axle two-by-two
It is spaced 120 degree between line.
Compared with prior art, the beneficial effects of the utility model are: by installing between transmission line wire
With the inter-phase spacer of antivibrator, 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 wire ice-shedding to insulation
The dynamic impact forces that substring, gold utensil and steel tower produce, prevents it from destroying.Meanwhile, antivibrator can subtract effectively
The internal force of inter-phase spacer self during little ice-shedding, prevents it from rupturing.Compare the most conventional separate type phase
Between conductor spacer, integral type inter-phase spacer have saving material, easy-to-install feature.
This utility model extensively can be applied in the transmission line of electricity of ice formation.

Detailed description of the invention
Below in conjunction with embodiment shown in the drawings, this utility model is described in further detail.
Alternate damping conductor spacer shown in Fig. 1, including three composite insulators, the one of each composite insulator
End is connected with wire, and the other end is connected with antivibrator；Three armed levers of this antivibrator are radially arranged, often
The end of individual armed lever connects a composite insulator.Figure shows: the axis of three armed levers of antivibrator is alternate
120 degree and be generally aligned in the same plane, and the axis of each armed lever is basic with the axis of the composite insulator being connected
Overlap.
In described composite insulator, silicon rubber umbrella skirt string string is enclosed within composite plug；Composite core
One end of rod is attached with described wire by metal wire clamp；Two aluminium alloy grading rings are separately fixed at multiple
On condensation material plug and abut against the two ends of silicon rubber umbrella skirt string, thus silicon rubber umbrella skirt string is carried out spacing.
Principle of the present utility model is (seeing Fig. 2): the alternate damping conductor spacer of this transmission line of electricity is by three of the wires
Connecting into an entirety, wherein during a wire ice-shedding, other two wires can produce resistance to it,
Reduce its jump height；Meanwhile, in antivibrator can effectively reduce conductor vibration amplitude and inter-phase spacer self
Power, prevents inter-phase spacer self from rupturing.
Finally it should be noted that listed above is only that this utility model is at 220kV heavy icing area single loop
Specific embodiment in transmission line of electricity.Obviously, this utility model is not limited to above example, it is also possible to application
In other electric pressure heavy icing area transmission lines of electricity.Those of ordinary skill in the art can be public from this utility model
The all deformation directly derived in the content opened or associate, are all considered as protection domain of the present utility model.
