Cable wire clamp shaped like Chinese character pin

Abstract

The invention provides a cable wire clamp shaped like a Chinese character pin. The cable wire clamp is fixed on a bracket through a bolt and comprises a cover plate, a base and a Y-shaped isolation assembly, the base is provided with the two connected grooves, and the connecting portion of the two grooves is a boss. The cover plate is fixed right below the base through a bolt, the cover plate andthe base are fixed into the shape of Chinese character pin, and the Y-shaped isolation assembly is inserted into the bosses, so that the impact load after a short-circuit fault of a cable is reduced,and the damage probability of the cable wire clamp is greatly reduced. According to the invention, the violent relative movement between the base and the isolation assembly can be hindered, the electromagnetic vibration energy of the cable during normal operation is consumed, the impact speed is reduced, the vibration reduction effect is improved, the cable wire clamp is not easy to damage, and the service life of the cable wire clamp is prolonged. According to the invention, through a flexible connection mode, the wire clamp is prevented from being damaged because of the fixed connection.

Description

technical field [0001] The invention relates to the technical field of power transmission network, in particular to a character-shaped 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 str...

AI Technical Summary

Problems solved by technology

The pin-shaped cable clamp in the current technology is a rigid connection, and the isolation component is only used to isolate the three-phase cable. After a short-circuit fault occurs on the rigidly connected cable, the cable is subject to a large impact load, which makes the cable clamp easily damaged.
