Description
Technical field
The present invention relates to power Transmission technical fields, more particularly to a kind of conducting wire for preventing overhead transmission line conductor from waving
Rotatable suspension clamp.
Background technique
Overhead transmission line (abbreviation route) is the important equipment of the energy of transmitting electric power, by route tower, conducting wire, aerial earth wire
Equal elements composition, the conducting wire of alternating current circuit includes A, B, C three-phase, and the conducting wire of DC line includes positive and negative the two poles of the earth.It is covered in certain
Non-uniform eccentric icing can be formed under ice and windy conditions, on conducting wire, changed the aerodynamic quality of conducting wire, easily caused conducting wire
Violent oscillatory motion, be visually known as waving.The distance between conducting wire can be reduced and electric discharge is caused to be tripped by waving；It can also increase and lead
Line tension simultaneously causes down tower, broken string, is one of the major failure for threatening transmission of electricity safety.
Every phase/polar conductor of the lower route of voltage is solid conductor；Every phase/polar conductor of the higher route of voltage is general
Certain distance is spaced apart from each other by several and is formed by the sub-conductor that certain shapes arranges, referred to as split conductor.According to sub-conductor number
Amount is further divided into binary fission, tripartition, quadripartion, six divisions and eight split conductors.Between two baseline road towers, led along division
Line fills a conductor spacer every tens of meter amperes and is used to support and fixes sub-conductor.
Split conductor is easier to wave than single conductor, this is caused by the icing difference of single conductor and split conductor
's.Winter Gale is moved along ground level, and the supercooling steam in air is blowed to conducting wire and is condensed in the windward side of conducting wire
Cheng Bing, referred to as eccentric icing.This bias icing can be generated using wire center line as the torque of rotation axis.
(1) for single conductor, which can make conducting wire rotate an angle, the windward side hair of such conducting wire by torque direction
Changing --- a part of conductive line surfaces within the scope of windward side have produced windward side and have not continued to icing originally；Without
A part of conductive line surfaces within the scope of windward side have been transferred to windward side and have started icing --- the windward side (i.e. Ice Area) of conducting wire
It is gradually changed with the rotation of conducting wire, finally forms the relatively uniform annular icing of a circle on conducting wire, and annular icing is led
Line is similar with no ice coating wire, is not easy to form lift, so the probability that single conductor is waved is relatively low.
(2) for split conductor, since conductor spacer secures sub-conductor, although there is moment loading of eccentric icing to lead
Line does not rotate, therefore its windward side (i.e. Ice Area) is fixed.As time went on, the icing of windward side gradually increases
Add, thicken, i.e., eccentric icing is increasingly severe.Compared with uniform annular ice coating wire, serious bias ice coating wire is easier to
Lift is formed, so the probability that split conductor is waved is relatively high.
The prior art is that the part fixed wire clamps of regular intervals stick are designed to revolution wire clamp, is formed between cable clip rotary type
Every stick.Wish that conducting wire clamped by revolution wire clamp has and effect and uniform icing effect is freely rotated similar to single conductor, from
And it is able to suppress split conductor also and waves.But on the route for having used cable clip rotary type conductor spacer on split conductor, wire clamp
Rotary conductor spacer to wave inhibitory effect unobvious；And without the route of conductor spacer on conducting wire, including single conductor and it is arranged above and below
The route of binary fission conducting wire still waves generation.
Include: according to the major reason that analysis causes the conducting wire on power transmission line to be waved
(1) one the reason is that current cable clip rotary type conductor spacer revolution wire clamp for conducting wire rotary resistance still compared with
Greatly, the torque that relatively thin lighter eccentric icing generates is not enough to rotate conducting wire.And conducting wire formed it is thicker it is heavier, be enough to rotate
Before the eccentric icing of conducting wire, waves and often have occurred and that.
(2) suspension clamp is that conducting wire forms eccentric icing and causes second important original waving to the rotary resistance of conducting wire
Cause.The element for being directly connected to and limiting conducting wire rotation on route with conducting wire includes conductor spacer and suspension clamp, and wherein conductor spacer is used
On conducting wire between steel tower, sub-conductor of the conductor spacer to support split conductor generally is filled every tens of meter amperes, due to
The packing density of conductor spacer is larger, is taken seriously for the rotation of conducting wire, icing and the influence waved；Suspension clamp is only in every base
It is used on steel tower (tangent tower), clamp conducting wire and hangs on conducting wire on tower, is i.e. the installation interval of suspension clamp is two base steel towers
The distance between, usually 300m-500m, although the conducting wire being clamped in suspension clamp is completely fixed, due to pendency
The packing density of wire clamp is much smaller than conductor spacer, thus it for the rotation of conducting wire, icing and the influence waved, there is no by foot
Enough attention.But suspension clamp between two base tangent towers conducting wire rotation restriction effect experiments have shown that: in distance
The farther away conducting wire middle section of suspension clamp, conducting wire rotational angle caused by eccentric icing is maximum, i.e., suspension clamp is for middle section lead
The restriction effect of rotation is relatively small；And it is closer apart from suspension clamp, conducting wire rotational angle caused by eccentric icing is smaller, i.e., outstanding
The restriction effect that vertical line folder rotates conducting wire is gradually increased.Therefore, suspension clamp can not neglect the restriction effect that conducting wire rotates
Slightly, it should also as the important factor in order of conductor galloping, which is directed not only to that the single conductor of conductor spacer is not used,
It is related to having used the split conductor of cable clip rotary type conductor spacer.
In conclusion the restriction effect that suspension clamp rotates conducting wire is the single conductor of no conductor spacer and has used wire clamp
The one of the major reasons that the split conductor of rotary conductor spacer is still waved.
Therefore, how to provide and can inhibit the conducting wire bias icing of transmission line of electricity and the suspension clamp of conductor galloping, be current
Technical problem urgently to be resolved.
