Embodiment 1

[0034] Such as figure 1 A new type of strain clamp is shown, the drain plate (2) of this strain clamp adopts a new type of structure, which is different from the structure type of the conventional strain clamp drain plate, and the conventional strain clamp drain plate is used as The load-bearing structure is also used as a conductive structure. The drain plate used in the tension clamp provided by the present invention separates the two functions of load-bearing and conduction. The fatigue resistance of the drain plate (2) of the strain clamp of this type of structure is The performance has been greatly improved, which can effectively reduce the phenomenon of fracture of the drainage plate under long-term fatigue.

[0035] There are four bolts on the original strain clamp drainage plate, and the drainage plate and the drainage clamp are fastened together by bolts, which are tightly fitted and cannot move relative to each other; the newly designed tension clamp drainage plate (...

Abstract

The invention provides a novel strain clamp. The novel strain clamp comprises a metal body (1), a current guiding plate (2), a current guiding wire clamp (3) and a fixing piece (5); one end of the current guiding plate (2) is connected with the current guiding wire clamp (3) through the fixing piece (5); the other end of the current guiding plate (2) is sleeved and fixed with the metal body (1); the metal body (1) and the current guiding wire clamp (3) are used for fixing a power transmission line; the current guiding plate (2) is used for bearing the gravity of a wire and the waving stress ofthe strain clamp. According to the novel strain clamp provided by the invention, the force bearing part and wire part of the strain clamp are respectively designed, so that the wire can be stably andeffectively held, and the phenomenon that the current guiding plate is broken under the action of long-term fatigue can be reduced.

Description

technical field [0001] The invention relates to the field of fittings for overhead transmission lines, in particular to a novel strain clamp. Background technique [0002] The tension clamp is used to fix the conductor or lightning conductor on the tension insulator string of the non-linear tower, and it acts as an anchor. It is also used to fix the guy wire of the guy tower. It is an important fitting in the transmission line. The overhead transmission line aims to build an "environmentally friendly" project, comprehensively optimize the design of the project, and strictly ensure that the electric field, magnetic field, audible noise and radio interference levels meet the standard requirements. [0003] At present, the commonly used hydraulic tension clamps are mainly divided into double-plate tension clamps and single-plate tension clamps according to the structure of the drainage plate. For areas with severe breeze vibration and frequent galloping, it is often The breaka...
