Description
Technical field
The present invention relates to the insulator field that electric power is carried, particularly a kind of damping insulator that is used for transmission pressure.
Background technology
According to the statistics of national grid department, by the end of the year 2009, existing 110 (66) KV of China and above ultra-high-tension power transmission line are counted roughly 553382 kilometers, and the conservative estimation of electric power pylon quantity has 1,800,000, and is increasing enormous amount rapidly.In recent years, natural calamities such as violent storm take place again and again, and therefore many electric power pylons damage even collapse, and bring about great losses to electrical network.
Summary of the invention
Technical problem to be solved by this invention provides a kind of damping insulator that is used for transmission pressure, can avoid electric power pylon and damage because of the whipping of transmission pressure.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is: a kind of damping insulator that is used for transmission pressure, comprise a plurality of umbrella disks that connect up and down, and the umbrella disk lower end is connected with wire clamp, also is connected with at least one buffer between a plurality of umbrella disks.
Described buffer is spring, elastic buffer or magnetic current liquid buffer.
In the described elastic buffer, piston is installed in the housing, piston is provided with a plurality of damping holes.
In the described magnetic current liquid buffer, piston is installed in the housing, piston is provided with at least one damping hole, is filled with magnetic current liquid in the housing, is provided with at least one group of coil near the damping hole, and the pilot of coil passes from piston rod.
Described a plurality of damping hole is uniformly distributed with on circumference, organizes outer ring and/or inner ring that coil is positioned at the circumference of a plurality of damping holes compositions more.
Described each damping hole is provided with the coil with the damping hole concentric outward.
Described each damping hole has crooked path.
Also be provided with the back-moving spring that is used to make piston reset.
Also be provided with resilient coating in the rodless cavity of housing.
Through carefully searching reason; The reason that electric power pylon damages is that the insulator that uses on China's electric power pylon at present all is the structure of not damping, as shown in Figure 7; Directly transmission pressure is connected with electric power pylon, electric power pylon has directly just been passed in the vibration that lead produces.And the span between the electric power pylon is generally more than 500 meters, and the lead between two towers is just as a huge rope skipping, lead to get rid of the vibration that pendulum produces be very fierce, the stress alternation of its generation is to bring the destructive main cause of damaging to electric power pylon.Especially during the break-in in the whipping process, instantaneous load produces synergistic effect, and its destructive power is huge.
Therefore adopted in the present invention and on insulator, added energy absorber to overcome stress alternation, the stress alternation of especially instantaneous stack is brought destructive the damage to electric power pylon.
A kind of damping insulator that is used for transmission pressure provided by the invention has overcome the stress alternation that transmission pressure produces through between umbrella disk, adding buffer, has protected electric power pylon effectively.

Embodiment
Embodiment 1:
In Fig. 1, a kind of damping insulator that is used for transmission pressure comprises a plurality of umbrella disks 1 that connect up and down, and umbrella disk 1 lower end is connected with wire clamp 3, also is connected with at least one buffer 2 between a plurality of umbrella disks 1.
Described buffer 2 is spring or elastic buffer.The spring (not shown) that is provided with separately can reduce stress alternation effectively, in the time of especially can overcoming in the whipping process break-in, and the synergistic effect that instantaneous load produces.
In the scheme of optimizing, as shown in Figure 6, in the elastic buffer of employing, piston 27 is installed in the housing 23, piston 27 is provided with a plurality of damping holes 25.Also be provided with and be used to back-moving spring that piston 27 is resetted.In this example, the combination of flexible member such as spring and damper because the damping curve of the two is different, thereby has further reduced vibration.Back-moving spring can be arranged on rod chamber, as shown in Figure 6, also can be arranged on rodless cavity, perhaps is arranged on rod chamber and rodless cavity simultaneously, perhaps is arranged on the outside of housing 23.In the rodless cavity of housing 23, also be provided with resilient coating 28, be used to prevent piston 27 direct and housing 23 collisions, have cushioning effect simultaneously.
Embodiment 2:
In Fig. 1, a kind of damping insulator that is used for transmission pressure comprises a plurality of umbrella disks 1 that connect up and down, and umbrella disk 1 lower end is connected with wire clamp 3, also is connected with at least one buffer 2 between a plurality of umbrella disks 1.
Described buffer 2 is a magnetic current liquid buffer.
As shown in Figure 2, in the described magnetic current liquid buffer buffers device, piston 27 is installed in the housing 23; Piston 27 is provided with at least one damping hole 25; Be filled with magnetic current liquid 24 in the housing 23, be provided with at least one group of coil 26 near the damping hole 25, the pilot 21 of coil 26 passes from piston rod 22.Magnetic current liquid is that magnetizable soft iron particles is suspended in the suspension liquid in the hydrocarbon solution, changes the flowability of magnetic current liquid through the size of current that changes coil 26, thereby changes the damping coefficient of damper.Magnetic current liquid buffer can change the coil current size according to the Oscillation Amplitude size information (for example wind speed size) of high-voltage conducting wires, controls the cushioning ability of magnetic current liquid buffer, to adapt to the transmission pressure damping under the different situations.Can lead be got rid of the vibration of putting generation like this and fall, and not pass to electric power pylon, play the effect of protection electric power pylon through buffer " absorption ".
In the scheme of optimizing, described a plurality of damping holes 25 are uniformly distributed with on circumference, organize outer ring and/or inner ring that coil 26 is positioned at the circumference of a plurality of damping holes 25 compositions more.Shown in Fig. 3, Fig. 4, this structure is for ease of processing and installation.
In the scheme of further optimizing, be provided with coil 26 outside described each damping hole 25 with damping hole 25 concentrics.As shown in Figure 5.The usefulness of this structure is higher.
In the scheme of further optimizing again, described each damping hole 25 has crooked path, promptly each damping hole 25 no longer with parallel axes; But crooked, the shape of spiral for example, thus effectively increased the length of damping hole 25; Improved damping, not shown.Adopt this structure can effectively reduce the volume of buffer.
In the scheme of optimizing, also be provided with and be used to back-moving spring that piston 27 is resetted.Under the action of gravity of transmission pressure, piston 27 always is tending towards resting on the top of housing 23, and this state is the vibrational energy that is unfavorable for absorbing lead, and therefore to adopt the auxiliary middle part that makes piston 27 rest on housing 23 of back-moving spring be useful.In embodiment 1, back-moving spring can be arranged on rod chamber or rodless cavity, perhaps is arranged on rod chamber and rodless cavity simultaneously, perhaps is arranged on the outside of housing 23, and is not shown.
Also be provided with resilient coating 28 in the rodless cavity of housing 23.Be used to prevent piston 27 direct and housing 23 collisions, have cushioning effect simultaneously.
