Multi-splitting bus

Abstract

The invention relates to a multi-split bus, which is characterized in that: 1, a tubular electric conductor adopts a multi-split conductor, an insulating layer is arranged between two conductors, and each conductor has two electric conducting surfaces; 2, a rectangular electric conductor adopts a multi-layer split conductor, an insulating layer is arranged between two conductors, each conductor has two electric conducting surfaces, and the like; and 3, in a stranded wire type electric conductor, each strand of each layer of a conductor has an insulating layer (each strand of the conductor of a path-resistant stranded wire has the insulating layer). The current-carrying capacity is large, the temperature rise is low, the weight is light, non-ferrous metals are saved, the energy is saved, and the environment is protected. Under low temperature, only a part of the split conductors transmit the prior rated current, and the temperature rise of the conductor is higher than normal temperature rise; and without power-off, ice and snow cannot be hung on the conductor so as to prevent the ice and the snow overwhelming lines to avoid power failure. The multi-split bus has wide social benefit on improving power supply reliability.

Description

technical field [0001] The invention relates to the use of power generation, power transmission and transformation, and power consumption units for conveying various voltage levels and large currents, which is safe and energy-saving, and belongs to a new invention technology. Background technique [0002] 1.——The existing high-current bus has less current carrying capacity and more consumables. The conductor material selected is copper or aluminum, and the conductor shape is tubular, rectangular, and twisted (wire, cable, steel-cored aluminum stranded wire), The above conductors are integral electrical conductors.

Problems solved by technology

[0009] In order to overcome the shortcomings of the prior art (its shortcomings: less current carrying capacity, more consumables, and inability to melt ice and snow, etc.), the present invention provides a multi-split busbar (multi-layer conductive tube, multi-layer rectangular conductor, multi-layer multi-layer stranded wire) ), the multi-split busbar passes through multiple splits on conductors with the same cross-sectional area. Each split conductor and each layer of split conductors is an independent insulated conductor. There is insulation isolation between conductors and between layers. The cross-sectional area can increase the conductive surface area of ​​the conductor, realize the increase of current carrying capacity, low temperature rise, light weight, and save energy
