Description
Technical field
The utility model relates to a kind of OPPC pre-hinged strain clamp, belongs to the technical field of power system transmission line aspect.
Background technology
Along with industrialized development, electricity needs is increasing, adds that energy-saving consumption-reducing measure is carried out by country, and power industry releases the transmission of electricity communication wire that a kind of optical fiber and phase line unite two into one.Only be used in the upper use of Optical Fiber composite overhead Ground Wire (OPGW) in the past, and used successfully in phase line further now.Just need a large amount of strain clamps to connect in actual installation.This novel conductive wire uses traditional strain clamp in actual installation, comprises wedge clamp and bolt-type strain clamp, but traditional strain clamp all exists its limitation used and shortcoming.Wedge clamp utilizes wedge shape to clamp phase line in cinching process, and the stress causing phase line to bear concentrates on very little position, thus causes damage to phase line, affects the useful life of phase line, and can not bear larger pulling force.Screw bolt-type utilizes bolt and clamping plate to apply pressure in vertical direction to phase line, utilizes the frictional force between them to reach fixed effect.This is that stress is concentrated on the very short position of phase line, Relatively centralized equally, easily damage phase line and fail safe is lower.
Summary of the invention
For the deficiency that the problems referred to above exist, the purpose of this utility model is, provides a kind of OPPC pre-hinged strain clamp.
A kind of OPPC pre-hinged strain clamp, comprise, the U-shaped ring A (1) mounted with connecting rod, it is characterized in that, the side of U-shaped ring A (1) is provided with U-shaped ring B (9), its U-shaped ring B (9) intersects with the ring portion of U-shaped ring A (1) and is connected, ball-eye (2) connecting insulator (3) that U-shaped ring B (9) is arranged by side, the side of insulator (3) is provided with socket-clevis eye (4), cardioid ring (5) bolt that described socket-clevis eye (4) and side are arranged is connected, preformed armor rods is sleeved on cardioid ring (5) by the breach (11) on cardioid ring (5), its preformed armor rods adopts double layer design: outer preformed armor rods (6) and internal layer preformed armor rods (7), OPPC Optical Fiber composite overhead Ground Wire (8) is had in the internal package of internal layer preformed armor rods (7).
Described preformed armor rods adopts the aluminium-clad steel wire of prefabricated spiral shape to make, and its outer preformed armor rods (6) is wrapped on the ceiling of internal layer preformed armor rods (7).
Described outer preformed armor rods (6) and cardioid ring (5) twisting part are divided into U-shaped structure.
The utility model has structure simple, easy for installation, and protection OPPC Optical Fiber composite overhead Ground Wire, not by the infringement that stress is concentrated, can bear larger load again.A whole set of connected mode meets the connection request in ring that State Grid installs and ring, bolt and hole, makes every effort to the maximization of connecting portion contact area, avoids point cantact, carry out insulation processing simultaneously to installation, guarantee use safety.

In figure: U-shaped ring A1, ball-eye 2, insulator 3, socket-clevis eye 4, cardioid ring 5, outer preformed armor rods 6, internal layer preformed armor rods 7, OPPC Optical Fiber composite overhead Ground Wire 8, U-shaped ring B9, bolt 10, breach 11.
Embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, a kind of OPPC pre-hinged strain clamp, comprise, the U-shaped ring A1 mounted with connecting rod, it is characterized in that, the side of U-shaped ring A1 is provided with U-shaped ring B9, described U-shaped ring B9 intersects with the ring portion of U-shaped ring A1 and is connected, ball-eye 2 connecting insulator 3 that U-shaped ring B9 is arranged by side, the side of insulator 3 is provided with socket-clevis eye 4, cardioid ring 5 bolt that described socket-clevis eye 4 and side are arranged is connected, preformed armor rods is sleeved on cardioid ring 5 by the breach 11 on cardioid ring 5, described preformed armor rods adopts the aluminium-clad steel wire of prefabricated spiral shape to make, take double layer design: internal layer preformed armor rods 7 is protective layer, outer preformed armor rods 6 is shell of tension, described outer preformed armor rods 6 is wrapped on the ceiling of internal layer preformed armor rods 7.Internal layer preformed armor rods 7 wraps up OPPC Optical Fiber composite overhead Ground Wire 8.
Described preformed armor rods, for the phase line of different wire diameter, being prefabricated into the helical form to phase line vertical direction there being precompression by particular manufacturing craft, organizing into groups online.Internal layer preformed armor rods 7 is divided into four groups in order to marshalling easy for installation, often group becomes an entirety through adhesion process, diamond dust on inside spin even application, its objective is the effect playing increasing friction force, hang on to OPPC Optical Fiber composite overhead Ground Wire 8, make the effective length of internal layer preformed armor rods 7 become as a whole with phase line.
Outer preformed armor rods 6 is the main undertaker of tension force, making adopt the wire diameter larger than internal layer preformed armor rods 7 be also made into helical form, by marshalling, bonding and the process of inside spin sandblasting diamond dust, U-shaped is made through stranded in advance with cardioid ring 5 connecting portion, the groove of itself and cardioid ring 5 is matched, thus form maximum contact-making surface, avoid point cantact.The afterbody of the outer preformed armor rods 6 of its U-shaped is wrapped on internal layer preformed armor rods 7 uniformly.
The quantity of setting up insulator 3 is required according to line design.
