Description
Technical field
The present invention relates to a kind of inter-phase spacer vibrationproof anti-dance spring damping devices, belong to electric system overhead transmission line
Design, operation, maintenance field.
Background technique
Anti-galloping interphase spacer can effectively contain that transmission line icing is waved, and since two thousand and ten, anti-galloping interphase spacer is
It is widely used in national overhead transmission line, there are easy to fall off, mills in anti-galloping interphase spacer use process
Disconnected conducting wire and the problem of making wire strand breakage, it has also become the hidden danger of electric power netting safe running.
In March, 2016, State Grid Corporation of China's fortune examine the 5.2nd article of explicit stipulation in [2016] No. 413 texts: " should be avoided " three
Across " across installing inter-phase spacer in shelves " (" three across " i.e. across railway, expressway and important passway for transmitting electricity).Open source literature is pointed out:
Inter-phase spacer is Canadian's long rod insulator that alternate conducting wire is mutually isolated earliest, and both ends configure fixed folder
Tool is that current asynchronous wave of anti-route leads to the highly effective tool of phase fault, but its both ends fixture constraint conducting wire reverses
Cause time span wire icing uneven, aggravates time span conducting wire oscillation and wave, wire tension increase causes aeolian vibration to aggravate, by force
Strong wave easily makes inter-phase spacer both ends generate galvano-cautery.Currently, in existing various anti-galloping interphase spacers, in addition to rubber hinders
Outside Buddhist nun, without apparent safe and reliable energy consumption damping unit, it is imperative to research and develop new and effective damping unit.
Currently, having " a kind of inter-phase spacer spring damping device (ZL201520520764.3) " and " between one kind is alternate
Every stick dual spring damping unit (ZL201520612248.3) " two patents can play obviously during transmission line icing is waved
Energy consumption effect, it is but little being acted in terms of aeolian vibration because of spring deformation very little, or even do not work.
Wire icing is waved completely contradicts with effect caused by aeolian vibration, wire icing wave be significantly, low frequency
Rate, wave as low as 2~3 meters of amplitude, greatly to 4~6 meters, and the aeolian vibration of conducting wire be by a small margin, high-frequency, Oscillation Amplitude
Only 1 times or 2 times of diameter of wire or diameter of wire, therefore, the theoretical calculation model of vibrationproof and anti-dance be it is completely different, together
One spring damping device can not can play anti-dance effect but also play vibrationproof because its coefficient of elasticity, deformation quantity are widely different
Effect, the technical problem can not capture so far.
