Technical field
The present invention relates to the insulator field, particularly a kind of damping insulator for transmission pressure of electric power conveying.
Background technology
According to the statistics of national grid department, ending for the end of the year 2009, the existing 110(66 of China) KV and above ultra-high-tension power transmission line count roughly 553382 kilometers, and the conservative estimation of electric power pylon quantity has 1,800,000 framves, and is increasing rapidly, enormous amount.In recent years, the natural calamities such as violent storm occur again and again, and therefore many electric power pylons damage and even collapse, and bring about great losses to electrical network.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of damping insulator for transmission pressure, and electric power pylon can be avoided to damage because of the whipping of transmission pressure.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of damping insulator for transmission pressure, and comprise multiple umbrella disk connected up and down, umbrella disk lower end is connected with wire clamp, is also connected with at least one buffer between multiple umbrella disk.
Described buffer is elastic buffer or magnetic current liquid buffer.
In described elastic buffer, be provided with piston in housing, piston is provided with multiple damping hole.
In described magnetic current liquid buffer, be provided with piston in housing, piston is provided with at least one damping hole, is filled with magnetic current liquid in housing, is provided with at least one group of coil near damping hole, and the pilot of coil passes from piston rod.
In described magnetic current liquid buffer, multiple damping hole is circumferentially uniform, and many group coils are positioned at outer ring and/or the inner ring of the circumference of multiple damping hole composition.
In described magnetic current liquid buffer, outside each damping hole, be provided with the coil with damping hole concentric.
In described magnetic current liquid buffer, each damping hole has bending path.
Also be provided with the back-moving spring for making piston reset.
Also resilient coating is provided with in the rodless cavity of housing.
Through carefully searching reason, the reason that electric power pylon damages is, the insulator that current China electric power pylon uses is all the structure of not damping, as shown in Figure 7, directly be connected with electric power pylon by transmission pressure, the vibration that wire produces directly just has passed to electric power pylon.And the span between electric power pylon is generally more than 500 meters, the wire between two towers is just as a huge rope skipping, and the vibration of getting rid of pendulum generation of wire is very fierce, and its stress alternation produced brings the destructive main cause damaged to electric power pylon.During break-in especially in whipping process, instantaneous load produces synergistic effect, and its destructive power is huge.
Therefore have employed in the present invention and add energy absorber on the insulator to overcome stress alternation, the stress alternation of especially instantaneous superposition brings destructive damage to electric power pylon.
A kind of damping insulator for transmission pressure provided by the invention, overcoming the stress alternation of transmission pressure generation, effectively protecting electric power pylon by adding buffer between umbrella disk.

Embodiment
Embodiment 1:
As in Fig. 1, a kind of damping insulator for transmission pressure, comprise multiple umbrella disk 1 connected up and down, umbrella disk 1 lower end is connected with wire clamp 3, is also connected with at least one buffer 2 between multiple umbrella disk 1.
Described buffer 2 is spring or elastic buffer.The spring (not shown) of independent setting can reduce stress alternation effectively, when especially can overcome break-in in whipping process, and the synergistic effect that instantaneous load produces.
In the scheme optimized, as shown in Figure 6, in the elastic buffer of employing, be provided with piston 27 in housing 23, piston 27 is provided with multiple damping hole 25.Also be provided with the back-moving spring for making piston 27 reset.In this example, the combination of the flexible members such as spring and damper, the damping curve due to the two is different, thus further reduces vibration.Back-moving spring can be arranged on rod chamber, as shown in Figure 6, also can be arranged on rodless cavity, or be arranged on rod chamber and rodless cavity simultaneously, or be arranged on the outside of housing 23.In the rodless cavity of housing 23, be also provided with resilient coating 28, for prevent piston 27 directly and housing 23 collide, there is cushioning effect simultaneously.
Embodiment 2:
As in Fig. 1, a kind of damping insulator for transmission pressure, comprise multiple umbrella disk 1 connected up and down, umbrella disk 1 lower end is connected with wire clamp 3, is also connected with at least one buffer 2 between multiple umbrella disk 1.
Described buffer 2 is magnetic current liquid buffer.
As shown in Figure 2, in described magnetic current liquid buffers, piston 27 is installed in housing 23, piston 27 is provided with at least one damping hole 25, be filled with magnetic current liquid 24 in housing 23, be provided with at least one group of coil 26 near damping hole 25, the pilot 21 of coil 26 passes from piston rod 22.Magnetic current liquid is the suspension liquid that magnetizable soft iron particles is suspended in hydrocarbon solution, is changed the mobility of magnetic current liquid by the size of current changing coil 26, thus changes the damping coefficient of damper.Magnetic current liquid buffer according to the Oscillation Amplitude size information of high-voltage conducting wires (such as wind speed size), can change coil current size, controls the cushioning ability of magnetic current liquid buffer, to adapt to the transmission pressure damping under different situations.Such vibration wire being got rid of pendulum generation is fallen by buffer " absorption ", and does not pass to electric power pylon, plays the effect of protection electric power pylon.
In the scheme optimized, described multiple damping holes 25 are circumferentially uniform, and many group coils 26 are positioned at outer ring and/or the inner ring of the circumference of multiple damping hole 25 composition.As shown in Fig. 3, Fig. 4, this structure is comparatively for ease of processing and installation.
In the scheme of further optimization, outside described each damping hole 25, be provided with the coil 26 with damping hole 25 concentric.As shown in Figure 5.The usefulness of this structure is higher.
In the scheme optimized further again, described each damping hole 25 has bending path, namely each damping hole 25 no longer with axis being parallel, but bending, the shape of such as spiral, thus the length effectively adding damping hole 25, improve damping, not shown.Adopt this structure can effectively reduce the volume of buffer.
In the scheme optimized, be also provided with the back-moving spring for making piston 27 reset.Under the Action of Gravity Field of transmission pressure, piston 27 is always tending towards the top that rests on housing 23, and this state is the vibrational energy being unfavorable for absorbing wire, therefore adopts back-moving spring to assist the middle part making piston 27 rest on housing 23 to be useful.With in embodiment 1, back-moving spring can be arranged on rod chamber or rodless cavity, or is arranged on rod chamber and rodless cavity simultaneously, more or be arranged on the outside of housing 23, not shown.
Resilient coating 28 is also provided with in the rodless cavity of housing 23.For prevent piston 27 directly and housing 23 collide, there is cushioning effect simultaneously.
