Abstract
The invention relates to an ultra-high voltage transmission line protective device, and in particular relates to a floating type conductor spacer. The conductor spacer comprises a connected claw for fixing a guide line and a conductor spacer substrate for fixing the connected claw, wherein the connected claw and the conductor spacer substrate are connected by a bolt. The conductor spacer is characterized in that the conductor spacer substrate is formed by two annular plates, corresponding holes are distributed on the two annular plates evenly, the left and right adjacent holes are arc slotted holes, the connected claw is arranged between the two annular plates by a bolt, round holes are arranged on the annular plate at one side of the connected claw, and the arc slotted holes are arranged on the annular plate at the other side of the connected claw. In the technical scheme, the rigidity connection between the guide lines of the existing conductor spacer is changed into flexible connection, thus completely solving the problems of guide line galloping, subspan oscillation and the like caused by wind trailing vortex of adjacent partial guide lines, and improving the running safety of an ultra-high voltage transmission line. The protective device has the advantages of reasonable structure, practicality and the like, and is very suitable for fixing multiple split guide lines in high-voltage and ultra-high voltage transmission lines.
Description
Technical field
The present invention relates to the extra high voltage network protector, particularly a kind of floating type conductor spacer.
Background technology
At present; Problems such as the superhigh pressure multiple division electricity transmission line is waved in order to solve, aeolian vibration, subspan oscillation; Mainly be to distribute the conductor spacer distance rationally, means such as damping conductor spacer, damper, anti-dance device, preformed stockbridge damper are installed according to transmission line parameter; The vibrations between the bundle conductor, wave reduction, to guarantee the safe operation of lead.The multiple fission conductor of forming by six roots of sensation separate conductors like present 750kV extra high voltage network; Adopt six division conductor spacers that the six conductors equidistance is fixed between the multiple fission conductor, because six division conductor spacers are with six conductors fixing rigidly connected be one, the influence of adjacent lead wind vortex wake in the bundle conductor like this; The leeward side lead is in the wake flow of the place ahead sub-conductor formation; Make the leeward side lead produce drag force and lift, and problems such as conductor galloping, subspan oscillation take place, wave for a long time and vibrate; Will make multiple fission conductor produce fatigue fracture, influence the safe operation of ultra-high-tension power transmission line in junction with six division conductor spacers.
Summary of the invention
In order to overcome defective and the deficiency that prior art exists, the purpose of this invention is to provide a kind of floating type conductor spacer that adjacent lead wind vortex wake influence causes problems such as conductor galloping, subspan oscillation that solves.
The present invention solves the technical scheme that its problem adopts: a kind of floating type conductor spacer; The connection pawl and the conductor spacer matrix that is fixedly connected pawl that comprise fixing cord connect between pawl and the conductor spacer matrix and are connected through bolt, it is characterized in that the conductor spacer matrix is made up of two annular plates; On two annular plates, be uniformly distributed with and have corresponding hole; Adjacent two holes, the left and right sides in above-mentioned hole are the arcuation long slot bore, connect pawl and are installed between two annular plates through bolt, the hole on the annular plate that connects the pawl both sides; One side is a circular hole, and opposite side is the arcuation long slot bore.
Be set with spacer sleeve on the above-mentioned bolt, spacer sleeve is installed between two annular plates, connects pawl and is contained on the spacer sleeve cylindrical.
The circular arc of above-mentioned arcuation long slot bore is concentric with annular plate.
Be uniformly distributed with the quantity that has corresponding hole on above-mentioned two annular plates and be 2 multiple.
Technical scheme of the present invention is rigidly connected with between the existing conductor spacer lead; Become and flexibly connect; Facing the wind as a side lead, when the leeward side lead was in the wake flow that the place ahead sub-conductor forms, the drag force of its generation will drive the annular plate that is connected a pawl and a side with lift; Along angle of annular plate rotation; Make the leeward side lead break away from velocity wake region, thoroughly solved problems such as conductor galloping that adjacent lead wind vortex wake cause, subspan oscillation, improved the security of operation of ultra-high-tension power transmission line.Characteristics such as that the present invention has is rational in infrastructure, practicality are fit to fixing of multiple fission conductor in high pressure and the extra high voltage network very much.

Embodiment
Floating type conductor spacer as shown in Figure 1 is made up of with the conductor spacer matrix that is fixedly connected pawl the connection pawl 1 of fixing cord, connects between pawl and the conductor spacer matrix to be connected through bolt 3.As shown in Figure 2, the conductor spacer matrix is to be combined by left annular plate 6 and right annular plate 2, about be uniformly distributed with on two annular plates and have 6 holes, wherein the hole at 120 ° at three intervals is an arcuation long slot bore 4, the circular arc of arcuation long slot bore is concentric with annular plate.3 holes are circular hole in addition, are distributed between three arcuation long slot bores 4.Connect the bolt 3 of pawl 1 through hole on two annular plates about passing, be installed between two annular plates, the hole on the annular plate of left side is a circular hole, and the hole on the annular plate of right side is the arcuation long slot bore.Connect pawl and can conveniently rotate along bolt two center lines for making, and guarantee the spacing between two annular plates on bolt 3, to be set with spacer sleeve 5, spacer sleeve is installed between two annular plates, and the connecting hole that connects in the pawl 1 is contained on the spacer sleeve cylindrical.
Like the multiple fission conductor that present 750kV extra high voltage network is made up of six roots of sensation separate conductors, adopt this floating type conductor spacer that the six conductors immobile phase is connected as a single entity.When prescription facings the wind in the wake flow that lead forms before the leeward side lead is in; The drag force of its generation will drive with lift and be connected pawl generation power up or down; Three leads through connecting pawl, spacer sleeve, bolt drive interval rotate along the arcuation long slot bore on the annular plate; Make the leeward side lead break away from velocity wake region, thoroughly solved problems such as conductor galloping that adjacent lead wind vortex wake cause, subspan oscillation, improved the security of operation of ultra-high-tension power transmission line.
When left side annular plate 6 and right annular plate 2 aggregate erections; What the circular hole on the annular plate of a left side was corresponding is the arcuation long slot bore on the right annular plate; So just three transmission lines with the space are connected as a single entity through connecting pawl, spacer sleeve, bolt and left annular plate 6; In addition three transmission lines and right annular plate 2 are connected as a single entity; The annular plate of one side just can rotate to an angle along the arcuation long slot bore on the annular plate of opposite side, and the quantity in hole can design according to the quantity of transmission line bundle conductor on the annular plate, as is designed to 4,6,8 etc. 2 multiple.
