Abstract

The invention provides an equipotential shielding tubular high-current bus and a preparation method therefor. The equipotential shielding tubular high-current bus comprises a shielding tube, wherein the shielding tube comprises a wave-transparent layer, an equipotential shielding layer, a main insulating layer, a wave absorbing layer and a protective layer; the tubular high-current bus is simple in structure and reasonable in design, and the wave-transparent layer is adopted to buffer a difference value between the wave absorbing layer and air impedance, so that the overall wave absorbing performance of the material is improved; the wave absorbing layer shielding is realized by counteracting an interference magnetic field by a reversing magnetic field generated by the high-conductivity material; by adopting the special-wave-transparent material insulating dielectric, high dielectric heat dissipation is realized; the current-carrying capability of the bus is improved, the bus loss is lowered, and the operating temperature is lowered; and the shielding layer, which is adopted to reduce electromagnetic radiation, is used for reducing, avoiding or eliminating adverse influence or harm to human health or various electronic equipment from electromagnetic radiation, so as to protect human health and the environment.

Description

technical field [0001] The invention relates to the technical field of equipotential shielding tubular high-current busbars, in particular to an equipotential shielding tubular type high-current busbar and a preparation method thereof. Background technique [0002] The equipotential shielded tubular high-current busbar is one of the transmission equipment for power transmission and transformation. The traditional insulated tubular high-current busbar has a particularly serious problem of electromagnetic radiation pollution. Electromagnetic radiation is more harmful to people. Electromagnetic radiation is the main cause of cardiovascular disease, diabetes, and cancer mutation; electromagnetic radiation can cause damage to the human reproductive system, nervous system, and immune system; Inducing factors of pathological changes; electromagnetic radiation directly affects children's growth and bone development, resulting in vision loss, retinal detachment, and decreased liver ...
