A conductor with a built-in multi-stranded core that reduces AC resistance

Abstract

The invention discloses a conductor with built-in multi-twisted inner cores which can reduce AC resistance. It includes an inner conductor which is fed with a positive direct current to make itself positively charged. The inner conductor includes a plurality of inner cores and fillers. The inner cores are mutually twisted into a bundle, and the outer surface of the bundled multiple inner cores is covered with an inner insulating layer, and the filler is filled between the bundled multiple inner cores and the inner insulating layer, and the inner insulating layer The outer surface is covered with an outer conductor for transmitting alternating current, the inner conductor, the inner insulating layer, and the outer conductor are concentric, wherein: the inner core, the filler, and the outer conductor are made of good conductor materials, and the inner insulating layer Made of insulating material. In AC power transmission, the present invention makes the free conductive electrons flowing in the outer conductor tend to be evenly distributed, reduces the AC resistance of the outer layer on the outer conductor, reduces power loss, and makes the outer conductor fully play the role of conductor, greatly improving the performance of the present invention. electrical conductivity and utilization.

Description

technical field [0001] The invention relates to a conductor which can reduce its own AC resistance, improve its utilization rate in AC power transmission, and has multiple inner cores twisted into bundles, belonging to the field of AC power transmission. Background technique [0002] At present, in the field of AC power transmission, there is a "skin effect" in the process of AC power transmission. The skin effect refers to a phenomenon that when there is an alternating current in the conductor, the alternating current flowing inside the conductor is unevenly distributed, and it is concentrated on the outer layer of the conductor (considered "skin") to flow. It can be seen from actual use that the skin effect makes the actual current inside the conductor smaller, and the current is concentrated on the outer layer of the conductor. As a result, the AC resistance of the free conductive electron flow in the outer layer of the conductor is increased, and the electrical energy lo...

It can be seen from actual use that the skin effect makes the actual current inside the conductor smaller, and the current is concentrated on the outer layer of the conductor. As a result, the AC resistance of the free conductive electron flow in the outer layer of the conductor is increased, and the electrical energy loss of the conductor is increased. increase so that the conductor is not fully utilized
