Abstract
The utility model relates to a strain clamp for connecting an overhead transmission line tower with an optical fiber composition phase conductor (OPPC) with large sections. The strain clamp comprises an external clamping shell, an upper half cone block, a lower half cone block and a pressing piece, wherein the upper half cone block is arranged at the upper half part of the external clamping shell, the lower half cone block is arranged at the lower half part of the external clamping shell, and the conical degrees of the external walls of the upper and lower half cone blocks are matched with the conical degree of the inner wall of the external clamping shell; a cutting groove is arranged on the side surface of the external clamping shell, thus the OPPC is embedded conveniently; in addition, the pressing block is arranged to play a role of fixing the OPPC. An installation boss is arranged on the external wall of the external clamping shell, and two rotatable pulling plates are installed on the installation boss. Installation holes are arranged at one ends of the pulling plates, and connection holes are arranged at the other ends of the pulling plates. The two pulling plates are respectively installed on the installation boss on the external side of the external clamping shell through the installation holes, and the connection holes are connected with other line hardwares.
Description
Technical field
What Optical Fiber Composite built on stilts phase line (OPPC) in the utility model heavy in section related to strain clamp is the strain clamp that a kind of aerial power transmission line shaft tower connects the built on stilts phase line (OPPC) of heavy in section Optical Fiber Composite.
Background technology
The preformed strain clamp of the general employing of the built on stilts phase line OPPC of existing heavy in section Optical Fiber Composite; This strain clamp is installed inconvenient; And because its material is generally aluminium Baogang and big with built on stilts phase line (OPPC) contact area of Optical Fiber Composite; Cause the temperature of strain clamp to exceed a lot, be unfavorable for the safety and stability of power transmission sequence, and do not satisfy the construction demand of national resources economizing type electrical network than the built on stilts phase line of Optical Fiber Composite (OPPC) surface temperature.
Summary of the invention
The utility model provides Optical Fiber Composite built on stilts phase line in a kind of heavy in section use strain clamp to the weak point of above-mentioned technology, is that a kind of temperature is not higher than the temperature that Optical Fiber Composite is maked somebody a mere figurehead phase line (OPPC), the strain clamp of easy to install, good reliability.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: Optical Fiber Composite built on stilts phase line strain clamp in heavy in section comprises clamping shell body, last half cone piece, following half cone piece and briquetting.At the clamping shell body first half half cone piece is housed, in clamping shell body Lower Half half cone piece down is housed, the last half cone piece and the outer wall tapering of following half cone piece and the inwall tapering of clamping shell body are complementary.Also offer grooving in the clamping sides of outer shell, make things convenient for Optical Fiber Composite to make somebody a mere figurehead phase line (OPPC) and insert, also be furnished with briquetting in addition, play the compound built on stilts phase line of fixed fiber (OPPC).
The said outer wall tapering of going up half cone piece and following half cone piece is 7 °～10 °; The inwall tapering of said clamping shell body is 7 °～10 °.
The outer wall of said clamping shell body is provided with installation base; Rotatable arm-tie is installed on the installation base; Said arm-tie one end is provided with installing hole; The other end is provided with connecting hole, and two arm-ties are installed on the installation base in the clamping shell body outside through installing hole respectively, and connecting hole is connected with the All other routes gold utensil.
Operation principle:
When the utility model uses; The built on stilts phase line (OPPC) of Optical Fiber Composite is inserted in the wire clamp through clamping shell body grooving; To go up the half cone piece again, descend the alignment of half cone piece to wrap up to the built on stilts phase line (OPPC) of Optical Fiber Composite, subsequently its inwall along the clamping shell body will be installed in the clamping shell body, pull arm-tie then; Along with the increase awl piece of pulling force is not maked somebody a mere figurehead phase line (OPPC) generation slippage with Optical Fiber Composite all the time, the awl piece will progressively slide in the shell body.Pull arm-tie with built on stilts phase line (OPPC) tension of Optical Fiber Composite, arm-tie is connected gold utensil and links to each other with other.
The beneficial effect of the utility model is: the built on stilts phase line (OPPC) of Optical Fiber Composite because the clamp groove that only adopts awl piece and the clamping of clamping shell body to form is fixedly clamped, thereby the utlity model has easy to install, safe and reliable advantage; Secondly, the load bindiny mechanism of wire clamp adopts yoke plate and cramping body boss manner to connect, and installs very flexible; The 3rd, the clamping shell body is all done bead with the awl piece, can increase the frictional force between built on stilts phase line (OPPC) of Optical Fiber Composite and the wire clamp wire casing, is that wire clamp has more fail safe and reliability; The 4th, briquetting and following half cone piece can the compound built on stilts phase lines of fixed fiber (OPPC), make things convenient for Optical Fiber Composite to make somebody a mere figurehead continuing of phase line (OPPC).
