Abstract
The invention discloses a high-voltage bus duct, which comprises a conducting bar, wherein the outer surface of the conducting bar is a cross-linked polyethylene layer, the thickness of the cross-linked polyethylene layer is not smaller than 12mm when voltage is 35KV, and the thickness of the cross-linked polyethylene layer is not smaller than 8mm when the voltage is 10KV. The high-voltage bus duct has the advantages that cross-linked polyethylene has excellent electrical performance, small capacitance, excellent anti-aging characteristic and ultra-high thermal deformation resistance, and dielectric loss is smaller than that of paper insulation and PVC (Polyvinyl Chloride) insulation, so that the cross-linked polyethylene meets the requirements of the insulating property of the bus duct on the high-voltage, high-power and big-current bus duct, has good high and low temperature resistance and has IP (Ingress Protection) 68; the cross-linked polyethylene layer simultaneously performs the functions of an insulation layer and a water-proof layer, so that the bus duct has excellent water-proof performance; since the insulation performance is reliable, the bus duct is more compact in structure, can be directly installed and used without the supporting of a shell, and occupies a small area.
Description
Technical field
The present invention relates to a kind of high voltage bus groove.
Background technology
By air insulation or epoxy resins insulation between busbar in existing bus duct, owing to insulation mode determines
Bus duct structural volume is big, Heavy Weight.And for high voltage bus groove, because its power is big, reach 35KV, so to busbar
Insulating requirements higher, including the quality of the performance such as waterproof, all directly influence the quality of bus duct, performance and safety.
Summary of the invention
It is an object of the invention to provide a kind of good insulation preformance, high voltage bus groove simple and compact for structure, be particularly suited for
Effective insulation under high-power high-current エ condition.
Technical scheme: a kind of high voltage bus groove, including busbar, described busbar outer surface is for cross-linking poly-こ alkene layer.
Optimal, during voltage 35KV, the thickness of described crosslinking poly-こ alkene layer is not less than 12mm；During voltage IOKV, described friendship
The thickness of connection polyethylene layer is not less than 8mm.The power of bus duct, electric current are compared cable etc. and are wanted big many, at normal operating temperature
Under the conditions of (90 DEG C), short trouble temperature (130 DEG C) and short circuit temperature (250 DEG C), cross-link poly-こ alkene layer and disclosure satisfy that big electric current
Pass through.
In the present invention, described busbar is copper bar, aluminum row or Copper-Aluminum compound row.
Optimal, described cross-linked polyethylene layer is laid in described busbar outer surface.
Optimal, described cross-linked polyethylene layer uses Modularized splice to form, and is in close contact described busbar outer surface, spells
Seam seals with colloid.It is zigzag occlusion that described module connects 1/2 wall thickness face at ロ.Cross-link poly-こ alkene module to be in close contact
Busbar outer surface, contributes to high efficiency and heat radiation, and module connects the structure of ロ when can effectively prevent high-voltage arc straight radial
Leak out.
Above-mentioned busbar peripheral hardware encloser body supports.Owing to the busbar insulating properties of bus duct of the present invention are fine, therefore pacify
Directly can be fixed busbar in target location during dress so that bus duct structure is compacter, the space taken is little, certainly
Can also be auspicious as common bus duct one, it is supported at busbar peripheral hardware encloser body, then overall in target location installation.
Described housing is metal shell or non-metal shell.
Beneficial effect: compared with prior art, it is an advantage of the invention that cross-linking poly-こ alkene has splendid electric property, Jie
Matter loss ratio paper insulation and PVC insulation will little, aging resistance characteristic that electric capacity is little, splendid and superpower heat-resistant deforming performance, make
Crosslinked polyethylene high-power, big electric current bus duct on meet the needs of its insulating properties, high and low temperature resistance is good,
Degree of protection reaches IP68；Cross-link poly-こ alkene layer and simultaneously work as the effect of insulating barrier and waterproof layer so that bus duct has excellent
Water resistance；Owing to insulating properties are reliable so that bus duct structure is compacter, it is not necessary to shell supports to be mounted directly and makes
With, take up an area space little.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in embodiment being described below required for make
Accompanying drawing be briefly described.
Fig. 1 is present configuration schematic diagram；
Fig. 2 is the left view of Fig. 1；
Fig. 3 is crosslinked polyethylene modular structure schematic diagram；
Fig. 4 is the left view of Fig. 3.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe wholely.
Below in conjunction with the accompanying drawings and specific embodiment, progressive the present invention is illustrated, it should be understood that these embodiments are merely to illustrate
The present invention rather than limit the scope of the present invention, after having read the present invention, each to the present invention of those skilled in the art
The amendment planting the equivalent form of value all falls within the application claims limited range.
As shown in accompanying drawing 1,2, a kind of high voltage bus groove, including busbar 1, busbar I is that copper bar, aluminum row or copper aluminum are multiple
The row of conjunction, busbar I outer surface is cross-linked polyethylene layer 2.The thickness of cross-linked polyethylene layer 2 is different according to electric pressure, voltage
During 35KV, the thickness of cross-linked polyethylene layer 2 is not less than 12mm；During voltage IOKV, the thickness of cross-linked polyethylene layer 2 is not less than 8mm.
Bus duct is installed, and the two ends of busbar I offer installing hole 4, can directly be fixedly mounted by busbar I by installing hole 4,
After one group of busbar control spacing installs,.Can also be auspicious as common bus duct one, first at busbar I peripheral hardware encloser body 3
It is fixed support, is manufactured into entirety, then overall in target location installation.Housing 3 is metal shell or non-metal shell.
The busbar of bus duct is pancake structure, arranges layer crosslinked polyethylene at its outer surface and wants difficulty a lot.No
As the cylindrical structural of cable, it is attached to wire outer surface with fashion of extrusion, the simplest.In the present invention, cross-linked polyethylene layer 2
Busbar I outer surface can be attached to, it is also possible to by custom-designed module, use module by conventional laying method
The method changing splicing, module is in close contact busbar I outer surface, is sealed with colloid by splicing seams.As shown in accompanying drawing 3,4, crosslinking
Polyethylene block size needs to set according to splicing, and it is zigzag 5 that module connects 1/2 wall thickness face at ロ, during module splicing, and saw
Profile of tooth is mutually twisted, and effectively prevents from leaking out during high-voltage arc straight radial.
