Problems solved by technology

Due to the large grid gap of about 10 meters, the ring formed by the ground grid and the cable shielding layer is relatively large. The measured value is close to 100A. Such a large current can burn the grounding terminal; in addition, after

Abstract

The invention discloses a multi-pin grounding shielded wire which comprises a cable body and N grounding mechanisms, wherein the cable body is cylindrical, and comprises a conductor layer, an insulating sheath and a shielding net from inside to outside in sequence; M exposed parts are arranged on the shielding net; each grounding mechanism comprises a grounding wire body and a grounding terminal; each grounding wire body is connected with the corresponding exposed part of the shielding net; each grounding terminal is connected with the corresponding grounding wire body; each grounding terminal comprises at least one grounding pin, and the grounding pin is grounded; N is greater than or equal to 3, and M is greater than or equal to N. The multi-pin grounding shielded wire adopts a cable multi-pin grounding manner, so that the loop current of a cable shielding layer is reduced. Besides, grounding points can be flexibly adjusted according to the actual use condition. The condition that the electric current which is generated by a high-intensity magnetic field and flows the cable shielding layer is too high can be effectively prevented, so that the grounding terminals can be prevented from being burnt, and the overall safe and stable operation of the can be ensured.

Description

technical field [0001] The invention relates to the technical field of electric cables, in particular to a multi-pin grounded shielded wire. Background technique [0002] In recent years, with the rapid development of power transmission technology in the power industry, the use of shielded wires has become more and more widespread. The shielded wire is a transmission line that uses a mesh braided wire to wrap the signal wire, usually braided copper mesh or copper (aluminum), the shielding layer needs to be grounded, and the external interference signal can be guided into the earth by this layer to prevent the interference signal from entering the inner layer Conductor interference also reduces the loss of the transmitted signal. At present, the industry mainly adopts two methods of single-ended grounding and double-ended grounding of the shielding layer. [0003] However, when the shielding layer is only grounded at one end, there is an induced voltage between the metal sh...
