Abstract
The invention discloses a high-voltage bus duct which comprises a conducting bar, wherein a crosslinked polyethylene layer is arranged on the outer surface of the conducting bar; the thickness of the crosslinked polyethylene layer is not less than 12mm when the voltage is 35KV, and the thickness of the crosslinked polyethylene layer is not less than 8mm when the voltage is 10KV. The high-voltage bus duct has the advantages that the crosslinked polyethylene has excellent electric property, less dielectric loss than that of paper insulation or polyvinyl chloride (PVC) insulation, small capacitance, excellent anti-aging properties and super-strong resistance to heat deformation, so the crosslinked polyethylene meets the requirements of the insulating property on the bus duct with high voltage, high power and heavy current and has excellent high/low-temperature resistance, and the protection grade can be up to IP68. The crosslinked polyethylene layer plays roles of an insulating layer and a waterproof layer, so the bus duct has excellent waterproofness. Because of the reliable insulating property, the bus duct is more compact in structure and small in floor area and can be directly arranged and used without support of a shell.
Description
Technical field
The present invention relates to a kind of bus duct, particularly a kind of high voltage bus groove.
Background technology
Pass through air insulation or epoxy resins insulation in the existing bus duct between the busbar, because insulation mode has determined that the bus duct structural volume is big, Heavy Weight.And,, reach 35KV because of its power is big for the high voltage bus groove, thus higher to the insulating requirements of busbar, comprise the quality of performances such as waterproof, all directly have influence on quality, performance and the safety of bus duct.
Summary of the invention
Goal of the invention: to the problems referred to above, the purpose of this invention is to provide a kind of good insulation preformance, high voltage bus groove simple and compact for structure, be particularly useful for the effective insulation under the high-power big electric current operating mode.
Technical scheme: a kind of high voltage bus groove, comprise busbar, said busbar outer surface is the crosslinked polyethylene layer.
Best, during voltage 35KV, the thickness of said crosslinked polyethylene layer is not less than 12mm; During voltage 10KV, the thickness of said crosslinked polyethylene layer is not less than 8mm.The power of bus duct, electric current are compared cable etc. and are wanted big many, and under normal operating temperature (90 ℃), short trouble temperature (130 ℃) and short circuit temperature (250 ℃) condition, the crosslinked polyethylene layer can satisfy big electric current to be passed through.
Among the present invention, said busbar is copper bar, aluminium row or the compound row of copper aluminium.
Best, the said crosslinked polyethylene layer said busbar outer surface that is laid in.
Best, said crosslinked polyethylene layer adopts modularization to be spliced, and closely contacts said busbar outer surface, and splicing seams seals with colloid.Said module spliced connection interface place 1/2 wall thickness face is the zigzag interlock.The crosslinked polyethylene module closely contacts the busbar outer surface, helps high efficiency and heat radiation, when the structure of module spliced connection interface can effectively prevent the high-voltage arc straight radial to external leakage.
Above-mentioned busbar is provided with housings support outward.Because the busbar insulation property of bus duct of the present invention are fine; Can directly fix in the target location when therefore installing busbar; Make the bus duct structure compact more, occupation space is little, can certainly be as common bus duct; Housing is set outside busbar supports, integral body is installed in the target location then.
Said housing is metal shell or non-metal shell.
Beneficial effect: compared with prior art; Advantage of the present invention is that crosslinked polyethylene has splendid electric property, dielectric loss than paper insulation and the PVC insulation is all little, electric capacity is little, splendid anti-aging characteristic and superpower heat-resistant deforming performance; Make crosslinked polyethylene on the bus duct of high-power, big electric current, satisfy the needs of its insulation property; High and low temperature resistance is good, and degree of protection reaches IP68; The crosslinked polyethylene layer plays the effect of insulating barrier and watertight composition simultaneously, makes bus duct have excellent waterproof property; Because insulation property are reliable, make the bus duct structure compact more, need not housing supports can directly install and use, and the occupation of land space is little.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the present invention; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Like accompanying drawing 1, shown in 2, a kind of high voltage bus groove comprises busbar 1, and busbar 1 is copper bar, aluminium row or the compound row of copper aluminium, and busbar 1 outer surface is a crosslinked polyethylene layer 2.The thickness of crosslinked polyethylene layer 2 is according to electric pressure and difference, and during voltage 35KV, the thickness of crosslinked polyethylene layer 2 is not less than 12mm; During voltage 10KV, the thickness of crosslinked polyethylene layer 2 is not less than 8mm.
When bus duct was installed, the two ends of busbar 1 offered installing hole 4, can after one group of busbar control spacing installs, get final product directly with busbar 1 fixed installation through installing hole 4.Also can earlier housing 3 be set outside busbar 1 and carry out fixed support as common bus duct, manufacture integral body, integral body is installed in the target location then.Housing 3 is metal shell or non-metal shell.
The busbar of bus duct is the pancake structure, at its outer surface one deck crosslinked polyethylene is set and wants difficulty a lot.Unlike the cylindrical structural of cable, attached to the lead outer surface, fairly simple with fashion of extrusion.Among the present invention, crosslinked polyethylene layer 2 can attached to busbar 1 outer surface, can also adopt the method for modularization splicing through custom-designed module through conventional laying method, and module closely contacts busbar 1 outer surface, and splicing seams is sealed with colloid.Like accompanying drawing 3, shown in 4, the crosslinked polyethylene block size is set according to the splicing needs, and module spliced connection interface place 1/2 wall thickness face is a zigzag 5, during the module splicing, the mutual interlock of zigzag, when effectively preventing the high-voltage arc straight radial to external leakage.
