Embodiment Construction

[0042] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0043] The embodiment of the present invention provides an in-line cable clamp, such as Figure 1-Figure 4 As shown, it realizes the functions of cable support and electrical conduction of various voltage levels, various spans, and various cross-sections, and bears various static loads during the installation and operation of cables, such as construction loads and axial deformation. Load, the in-line cable clamp provided by the embodiment of the present invention includes a plurality of clamps and damping components; the embodiment of the present invention uses three clamps, and the clamps are respectively flexibly connected by damping components to form an in-line cable clamp;

[0044] Wherein, at least one wire clip is used for fixed connection with the bracket and at least one wire clip is used for flexible connection with the bracket, and the damping asse...

Abstract

The invention provides a line-shaped cable clamp. The line-shaped cable clamp comprises a plurality of cable clamps and a damping assembly, and the wire clamps are flexibly connected through damping assemblies to form a linear cable wire clamp, wherein the at least one wire clamp is used for being fixedly connected with the support, the at least one wire clamp is used for being movably connected with the support, the damping assembly is used for absorbing impact loads in the linear direction, the impact loads generated after a short-circuit fault happens to the cable are reduced, and the damage probability of the cable wire clamp is greatly reduced. According to the invention, flexible connection is realized through the damping assembly; violent collision or high-frequency vibration between different phase wire clamps can be hindered; electromagnetic vibration energy of the cable during normal operation is consumed, the impact speed is reduced, the vibration reduction effect is improved, the cable clamp is prevented from being damaged due to fixed connection, the service life of the cable clamp is prolonged, and the cable clamp is suitable for different voltage classes, cable diameters, stand column intervals and tunnel sections.

Description

technical field [0001] The invention relates to the technical field of power transmission network, in particular to an inline cable clamp. Background technique [0002] With the continuous improvement of the level of urbanization, the demand for power transmission and distribution cables in urban construction will continue to grow, and the construction of urban cable lines and the design technology of power cable lines will continue to develop. The laying forms of high-voltage power cables mainly include cable tunnels, pipes, cable trenches, etc. The fixing and support of cables and their accessories mainly rely on the installation and use of cable fittings. [0003] Cable fittings mainly include clamps, brackets and columns, and the whole is arranged in sections at a certain interval. The cable is fixed and installed on the bracket through the clamp. When a short-circuit fault occurs in the power grid, a large short-circuit current will be generated, forming a strong magne...
