Rectangular-cross-section conductor internally provided with multiple inner cores and capable of reducing AC resistance

Abstract

The invention discloses a rectangular-cross-section conductor internally provided with multiple inner cores and capable of reducing AC resistance. The conductor includes an external conductor which is used for transmitting AC and has a rectangular cross section. In the external conductor, the plurality of inner cores are arranged in parallel uniformly in an embedded manner and used for allowing positive AC to pass so as to be electrified with positive charge. The outer surface of each inner core is wrapped with a layer of internal insulating layer. The inner cores and the external conductor are made of a good conductor material. The internal insulating layers which prevent positive charge in the inner cores from entering the external conductor are made of an insulating material. During AC power transmission, the conductor is capable of enabling free conductive electrons flowing in the external conductor to tend to be distributed uniformly so as to reduce the AC resistance on an outer surface layer of the external conductor and reduce electric energy consumption brought to the conductor because of the AC resistance so that the external conductor is enabled to play fully a conductor role and thus the utilization rate of the conductive performance of the conductor in electric power transmission is improved significantly.

Description

technical field [0001] The invention relates to a rectangular-section conductor with a plurality of inner cores built in, which can reduce its own AC resistance and improve its utilization rate in AC power transmission, and belongs 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 elec...

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
