Abstract

The utility model relates to an anti-adhesion and anti-whiplash along-line double-split four-clamp spacer for overhead transmission lines and relates to the electric power technical field. The anti-adhesion and anti-whiplash along-line double-split four-clamp spacer for overhead transmission lines comprises four clamps, four pressing plates and four spacer ball columns; a ball socket is arranged in each clamp; each spacer ball column comprises a ball head and a steel column, wherein the ball head is arranged in a corresponding ball socket, and the steel column is provided with an external screw thread; the four steel columns are connected together through a spacer frame; the spacer frame includes two transverse rods which are parallelly distributed; the transverse rods are connected with each other through connecting rods; two ends of each transverse rod are respectively provided with a threaded hole; each steel column is arranged in corresponding threaded holes so as to be in threaded connection with the transverse rods; and each steel column is in threaded connection with three hex nuts, wherein one of the hex nuts on the steel column is arranged at one side of a corresponding transverse rod, and the other two hex nuts are arranged at the other side of the corresponding transverse rod. Based on the above design, the interval between two conductors is adjustable, and sub conductors can be supported.

Description

The two division of the anti-whiplash fair line of prevent adhesion four wire clamp conductor spacers for overhead transmission line

Technical field

The utility model relates to power technology field, particularly the two division of the anti-whiplash fair line of prevent adhesion four wire clamp conductor spacers for a kind of overhead transmission line.

Background technology

In overhead transmission line, often due to reasons such as wind excitation, wire icing, line constructions, there is conductor galloping.Can frequently there is the phenomenons such as sub-conductor adhesion, whiplash, degree of speeding reduction in some many division circuit.After sub-conductor sticks together, the geometry spacing of bundle conductor significantly reduces, and corona discharge starting voltage reduces, and causes easily occurring corona discharge, and local direct-to-ground capacitance also reduces, and these all can cause the increase of line loss and the interference near communication apparatus.More serious situation is, bundle conductor occurs after adhesion, and wire whiplash phenomenon is outstanding, and the mutual serious wear of wire, not only further increases line loss, also can cause the accident of disconnected strand of wire, broken string.

Normal conditions mainly adopt the method that installs conductor spacer on wire additional to solve this problem now.But existing conductor spacer structure is all in a plane perpendicular to wire, in the middle of a lot of pairs of division circuits, can be offset in suitable wire direction every rod and the tie point of sub-conductor, can not play the effect of supporting sub-conductor, sub-conductor adhesion still occurs, cause power-off.

Summary of the invention

The purpose of this utility model is in order to overcome the deficiencies in the prior art, provides the two division of the anti-whiplash fair line of a kind of overhead transmission line prevent adhesion four wire clamp conductor spacers, and two wire pitch are adjustable, and can play the effect of supporting sub-conductor.

The purpose of this utility model is achieved in that the two division of the anti-whiplash fair line of overhead transmission line prevent adhesion four wire clamp conductor spacers, comprise four wire clamps, four block pressur plates, four conductor spacer goalpost, every block pressur plate is connected with wire clamp by bolt respectively, every block pressur plate arranges respectively half slot with corresponding wire clamp inner side, rubber tile is set respectively in each half slot, ball-and-socket is set respectively in each wire clamp, described each conductor spacer goalpost comprises respectively bulb and steel column, each bulb is separately positioned in corresponding ball-and-socket, on described every steel column, external screw thread is set respectively, four steel columns connect by conductor spacer framework, conductor spacer framework comprises two cross bars that are arranged in parallel, between two cross bars, connect by connecting rod, the two ends of every cross bar arrange respectively screwed hole, every steel column is separately positioned in corresponding screwed hole and is threaded with cross bar, three hex nuts are threaded respectively on every steel column, one of them hex nut on every steel column is arranged on a side of cross bar, two other hex nut is arranged on the opposite side of cross bar.

Of the present utility model by above design, two groups of wire clamps, cover plate on a wherein cross bar of conductor spacer are connected respectively a root wire with two groups of wire clamps, pressing plate on another root cross bar.Conductor spacer goalpost bulb part is connected with the ball-and-socket of wire clamp, pressing plate can be done 360 ° and rotate freely, and there is rubber tile in wire clamp, pressing plate, there is damping function, the sub-conductor that can effectively dissolve in fair line direction is waved, steel column part and conductor spacer framework bolt hole are threaded connection, and can realize the electrodeless adjusting of two wire pitch.The bolt hole upper surface of conductor spacer framework and lower surface are respectively provided with one group of spring washer, plain washer and hex nut for reinforcing being connected of goalpost and conductor spacer framework.
