Description
Technical field
The utility model relates to the conductor spacer that a kind of superhigh pressure, UHV transmission line are used, particularly preformed binary fission anti-skid ball strand conductor spacer.
Background technology
At a distance, jumbo superhigh pressure, UHV transmission line, every phase conductor has adopted two, three, four, the six roots of sensation, eight and above oidiospore lead.In order to satisfy electric property, reduce the surface potential gradient, and under short-circuit conditions, unlikely generation electromagnetic force causes attract each other collision, whiplash between wire harness, though or the attraction that causes moment is collided, but can return to the normal condition of the spacing of design after accident is eliminated, need to guarantee that bundle conductor wire harness spacing remains unchanged, need in span, suitable position be installed by the conductor spacer of suitable specification and quantity for this reason.Lead spacer is installed, can also plays certain inhibitory action to subspan oscillation and aeolian vibration simultaneously.
The binary fission conductor spacer of typing is a ball strand conductor spacer.As shown in Figure 1, its design feature is: the connected mode of the tangle ball rod 5 and 6 riveted joints of stay pipe 7 employing aluminium alloy rivets of (1) ball strand conductor spacer, at the long-term long duration of action owing to the gentle breeze vibration in service, rivet and riveted joint place are easy to generate wearing and tearing and cause the accident, and exist hidden danger is installed.(2) connection of ball being twisted the wire clip body 1 of conductor spacer by bolt and nut 3 realizes being connected of bulb stay pipe 5 and wire clip body 1 with ball gland 4 locking.(3) ball strand conductor spacer has adopted chuck formula structure, conductor spacer is to the clamping of lead 8 and holding by bolt and nut 3 fastening wire clamps 1 and line pressure lid 2 and realizing, the stress surface of lead 8 is confined within the width of chuck, be generally tens millimeters, stress area is too small, exists because of producing stress to concentrate the safe addiction of damage wires to suffer from.(4) the chuck formula structure of ball strand conductor spacer, need wire clip body 1 be fixed on the lead 8 by bolt and nut 3, owing to used bolt and nut, so need strict control mounting torque when installing, otherwise, thereby perhaps cause because of mounting torque is less than normal conductor spacer to the clamping of lead partially pine cause suitable the line grip of conductor spacer not up to standard, thereby perhaps cause conductor spacer that the clamping tension of lead is caused excessive compression damage lead to lead because of mounting torque is excessive, have the deficiency of secure context.(5) mode that fixes by bolt and nut of ball strand conductor spacer is installed on the lead, erection stage, and the fitting operation personnel need be with corresponding instrument (as: torque spanner etc.) to climb to carry out work high above the ground on the tower, and homework burden is bigger, inefficiency.(6) acceptance phase, for accurately check each wire clamp even each bolt mounting torque whether meet the requirements, the technical staff has to go up shaft tower by the base climbing, one by one the mounting torque of conductor spacer is measured, workload is big, and working strength is big, work difficulty is big, and is dangerous big.(7) if the installation process operating personnel are careless, bolt and nut may be from landing on the shaft tower, gently then causes bolt and nut to fall into thick grass or mountain valley and lose, and is heavy then hit the staff who assists under the tower and cause security incident.
