Coal mine area shielding monitoring type cable and using method thereof

Abstract

The invention discloses a coal mine area shielding monitoring type cable and a using method thereof. The cable comprises a cable body, a rubber protective sleeve, a protective sleeve and a copper net shielding layer, a blocking layer is fixedly connected to the interior of the copper net shielding layer, and a copper platinum shielding layer is fixedly connected to the interior of the blocking layer; and a first insulating layer is fixedly connected to the interior of the copper platinum shielding layer. According to the invention, through the arrangement of flow guide balls, the copper net shielding layer and the copper platinum shielding layer, sufficient shielding protection can be carried out on wires in the cable body, when the cable is subjected to electromagnetic interference, the cable body firstly blocks interfering electromagnetism through the copper net shielding layer, and the electromagnetism is directly poured out of equipment through the flow guide balls, so that the electromagnetism is guided to the ground; part of the electromagnetism penetrating through the copper net shielding layer can be absorbed by the copper platinum shielding layer again and then discharged through an equipment grounding port, the shielding effect of the equipment is greatly improved through the two-layer shielding mode, and therefore the use efficiency of the equipment is effectively improved.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a shielded monitoring cable used in coal mine areas and a method for using the same. Background technique [0002] The shielded monitoring cable is a transmission line that uses a metal mesh braid to wrap the signal line. The braid is usually red copper or tinned copper. The shielding is to ensure the transmission performance of the system in an environment with electromagnetic interference. The anti-interference here It should include two aspects, that is, the ability to resist external electromagnetic interference and the ability of the system itself to radiate electromagnetic interference. The necessary electromagnetic waves, which is also the method used by most shielding systems. [0003] For shielded monitoring cables, it is not enough to have a metal shielding layer, and more importantly, the shielding layer must be completely and well grounded, so that the interference cu...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of shielding monitoring type cable for coal mine area and its use method, to solve the design of existing coal mine area shielding monitoring type cable that adopts insulating layer and shielding layer to add wire more in the above-mentioned background technology, although It can better shield and protect the wires, but the shielding ability is limited. When used in complex coal mining areas, it still causes the wires to be easily interfered by electromagnetic interference, which affects the normal operation of the equipment.
