Technical field
The present invention relates to ultra-high-tension power transmission line Anti-galloping fields, more specifically to a kind of double bundle conductor Anti-galloping
Conductor spacer soft connection device.
Background technique
The anti-bouncing spacer of current power transmission route double bundle conductor installation, is dangled using vertical way double-line between sub-conductor line
The fixed mode of wire clamp, waveform when conductor vibration along wire to upper and lower bending, conducting wire each point all there is sizes not
With dynamic bending stress, especially at suspension clamp, due to the restriction at wire clamp by fixed connecting plate, in wire clamp, dynamic bending stress is most
Big and duration longest, will be such that conducting wire bends repeatedly, easily lead to conducting wire tired stranded, broken string in wire clamp, stranded, disconnected
In anti-bouncing spacer suspension clamp, route is normally maked an inspection tour to be difficult to find in time line point, easily causes great power grid accident, and
And route repairing difficulty is big, time-consuming, at high cost.
In order to improve status, it is ensured that transmission line safety stable operation is analysed in depth and visited in conjunction with defect in recent years
It begs for, stranded, broken string situation did not occurred at wire clamp for the single conductor of discovery installation wire-clamp-type anti-bouncing spacer, and double divisions are led
Line installation anti-bouncing spacer occurred repeatedly it is stranded, broken string situation, it can be concluded that go out occur wire strand breakage, broken string
Really " arch-criminal " is stationary type vertical way double-line suspension clamp.As shown in Figure 1, upper sub-conductor and lower son are led in prior-art devices
Connection between line (average spacing 400mm) is fixed, it is easy to because of the dance between upper sub-conductor and lower sub-conductor
It moves and larger stress is generated to form damage to conducting wire.Therefore 50 many places of stranded defect that Dalian Area occurs, or even have disconnected
The generation of line accident makes sub-conductor catenary if vertical way double-line suspension clamp, which is fixedly connected with mode, is changed to the mode that is flexible coupling
There are certain activity nargin between folder, can effectively reduce the vibrational energy in wire clamp, reduce wire strand breakage, broken string risk,
Improve power supply reliability.
