Clamp type cable sheath grounding cabinet

Abstract

The invention discloses a clamp-type cable sheath grounding cabinet, comprising a support frame arranged on the ground, a cabinet body and a plurality of grounding copper bars and characterized in that a right-angled edge strip with holes is respectively arranged on four corners in the cabinet body in the height direction, a plurality of fixed plates I and fixed plates II installed in the width direction of the cabinet body are arranged between the adjacent right-angled edge strips, a plurality of transverse copper bars I or transverse copper bars II are arranged perpendicular to the fixed plates I in the width direction of the cabinet body at intervals, the transverse copper bars I or the transverse copper bars II are installed on the fixed plates I through insulators I, longitudinal copper bars I are fixed on the transverse copper bars I, longitudinal copper bars II are fixed on the transverse copper bars II, total leading-out copper bars I are fixed on the longitudinal copper bars I, total leading-out copper bars II are fixed on the longitudinal copper bars II, and the total leading-out copper bars I and the total leading-out copper bars II are supported by insulators II fixed on the right-angled edge strips. The clamp-type cable sheath grounding cabinet radically solves the problems of disordered installation mode, poor uniformity, poor anti-interference property, poor resistance uniformity and the like when a cable shielding layer is grounded.

Description

technical field [0001] The invention relates to the installation field of cables or wires protected by a box, in particular to a clamp-type cable sheath grounding cabinet, which is mainly suitable for grounding the shielding layer of signal cables in railway signal systems. Background technique [0002] At present, there is no unified standard for the installation method of the grounding of the signal cable shielding layer in the railway signal system. The on-site installation method is chaotic, the installation is not neat, and the uniformity is poor. The protection effect is poor, the length of the grounding wire is different, and the grounding resistance of the cable shielding layer is not consistent. [0003] The existing cable grounding device, such as the invention patent application publication number CN104821539A, which discloses "the invention discloses a cable grounding box", includes an outer box, an inner box is arranged in the outer box, and the inner box It ca...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a clamp-type cable sheath grounding cabinet, which fundamentally solves the problems caused by the confusion and poor uniformity of the installation mode of the grounding of the cable shielding layer, and the non-independent setting of the steel armor sheath and the aluminum sheath grounding channel of the cable. Poor anti-interference performance, poor consistency of grounding resistance of cable shielding layer caused by uneven length of grounding wires, etc.
