Abstract

The invention discloses an ultralow magnetic field cable. The ultralow magnetic field cable sequentially comprises a cable core, a wrapping tape and an outer sheath from inside to outside, wherein the cable core comprises seven insulation wire cores and a filler filling between the insulation cores and the wrapping tape, the seven insulation wires are respectively an N-phase insulation wire core and two A-phase insulation wire cores, two B-phase insulation wire cores and two C-phase insulation wire cores which encircle the N-phase insulation wire cores, and the two A-phase insulation wire cores, the two B-phase insulation wire cores and the two C-phase insulation wire cores are respectively and symmetrically arranged by 180 degrees and are respectively connected in parallel. By designing a symmetric and reverse structure, each phase line of three phase lines A, B and C is divided into two cores, the cables are arranged in a cabling way and are symmetrically arranged with each phase being 180 degrees, and the electromagnetic quantity of each phase in the power transmission process forms an equivalent reverse mode; and since the accumulation of the electromagnetic quantity is vector accumulation, mutual offset is formed, and the purpose of an ultralow magnetic field is achieved.

Description

technical field [0001] The invention relates to a cable, in particular to a power cable capable of generating an ultra-low magnetic field in the process of AC power transmission. Background technique [0002] Industry 4.0 and intelligent manufacturing have become the development direction of China's manufacturing industry. So how to realize intelligent manufacturing is the problem we need to solve at present. Intelligent manufacturing should include intelligent manufacturing technology and intelligent manufacturing system. Intelligent manufacturing system can not only continuously enrich the knowledge base in practice, have self-learning function, but also collect and understand environmental information and its own information, and analyze and judge and plan itself. behavioral capacity. Therefore, in the modern industrial manufacturing system, the integration process of sensory IoT from intelligent perception, intelligent communication, intelligent processing and intellig...
