Problems solved by technology

[0003] Since the busbar carries large current and high voltage in the process of power transmission, the busbar products have extremely high requirements on insulation performance and fire resistance performance, but the existing busbar insulation layer is still difficult to meet the performance requirements under special circumstances

[0026] see figure 1 and figure 2 , which discloses the first embodiment of the dense insulated busway of the present invention, including a busbar protective shell 10 and a number of busbars 20 arranged in the busbar protective shell 10, and these busbars 20 are arranged side by side in parallel and closely adjacent to each other. The busbars 20 arranged side by side in parallel and closely adjacent to each other are covered with a ceramic foam insulation layer 30 .

[0027] The busbar 20 includes a busbar conductor 21 , a ceramicized silicone rubber insulating layer 22 covering the busbar conductor 21 , and a heat shrinkable sleeve 23 heat-shrinkable on the ceramicized silicone rubber insulating layer 22 .

[0028] The ceramicized silicone rubber insulating layer 22 is preferably formed by at least one ceramicized silicone rubber composite tape wound on the busbar conductor 21, and multiple ceramicized silicone rubber composite tapes can be wound, for example, 2 layers, 3 l...

Abstract

The invention discloses busbars which comprise busbar conductors, ceramic silicon rubber insulating layers wrapped on the busbar conductors, and heat-shrinkable sleeves. The ceramic silicon rubber insulating layers are formed by ceramic silicon rubber composite belts in a winding mode or in an extruded mode. The invention further provides an intensive insulating bus duct which comprises a busbar protective shell and a plurality of busbars arranged in the busbar protective shell. The busbars are adjacently arranged in parallel side by side, and a ceramic foaming heat insulating layer is wrapped outside the busbars which are adjacently arranged in parallel side by side. Compared with the prior art, the ceramic silicon rubber insulating layer is excellent in flame resistance and fire resistance, even though the ceramic silicon rubber insulating layer exceeds duration of fire resistance to burn, the ceramic silicon rubber insulating layer can still be burned to form the firm protective shell which can prevent the busbar conductors from being damaged, and ensures the normal using function of the busbars. Except for the flame resistance and fire resistance of the ceramic silicon rubber, the ceramic foaming heat insulating layer has the advantages of small density, light mass, heat insulation, heat preservation and the like. Therefore, the ceramic foaming heat insulating layer can prevent the outside high temperature from being conducted to the interiors of the busbars, and ensure the normal using function of the busbars.

Description

technical field [0001] The invention relates to a busbar and a dense insulated bus duct including the busbars. Background technique [0002] Bus line (bus line) refers to products made of high-conductivity copper (copper row) and aluminum materials to transmit electric energy and collect and distribute electric power. It is the main conductor used to transmit electric energy in power stations or substations, through which the electric energy output by generators, transformers or rectifiers is transmitted to various users or other substations. [0003] Since the busbar carries large current and high voltage in the process of power transmission, the busbar products have extremely high requirements on insulation performance and fire resistance performance, but the existing busbar insulation layer is still difficult to meet the performance requirements under special circumstances. Contents of the invention [0004] The object of the present invention is to provide a busbar wi...
