It is a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those skilled in the art exist
The every other embodiment being obtained under the premise of not making creative work, broadly falls into the scope of protection of the invention.
Refer to Fig. 1 and Fig. 2, it is a kind of overall structure figure and the STRUCTURE DECOMPOSITION of present invention low-voltage hollow bus duct respectively
Figure.With emerging in large numbers of modernization project facility and equipment, the fast increasing of power consumption of all trades and professions, especially numerous skyscraper and
The appearance in large-sized workshop workshop, the traditional cable as transmission pressure can not meet requirement in high current induction system, many
The used in parallel of road cable brings inconvenience to in-site installation construction connection.Plug type bus duct is as a kind of new distribution
Wire arises at the historic moment, and compared with traditional cable, fully demonstrates its superiority when high current conveys, simultaneously because adopting
New technology, new technology, the bus duct both ends junction substantially reducing and the contact resistance of branching port splicing position and temperature rise, and
Employ high-quality insulating materials in bus duct, thus improve the security reliability of bus duct, make whole system more
Perfect.Bus duct in the present embodiment, is the improvement further to existing bus duct, for but be not limited only to above-mentioned occasion.
As illustrated, the bus duct in the present embodiment, including housing, enclosure interior is divided into multiple parallel insulated cavities,
One conductor 1 of setting in each insulated cavity, described conductor 1 is low-voltage hollow conductor, and described housing includes upper shell 31 and lower casing
Body 32, described upper shell 31 is fixedly connected with lower house 32.The connection end setting of the corresponding lower house of of described upper shell 31
There is outside clad structure, another connection end is provided with evagination waterproof construction；Described lower house 32 has identical with upper shell 31
Connection end, upper shell 31 and lower house 32 pass through screw 33 or rivet fixing when, the outside clad structure of upper shell 31 with
The outside clad structure of housing 32 encases the evagination waterproof construction of lower house 32 and the evagination waterproof of upper shell 31 respectively from outside
Structure, screw 33 or rivet pass through outside clad structure to fix with evagination waterproof construction.Each described insulated cavity is by upper insulating part
21st, lower insulating part 22 and two phase insulation parts 23 surround, and are provided with a phase insulation part between two adjacent insulated cavities
23.One group of opposite side of the cross section of described conductor 1 is isometric line segment, and another group of opposite side is the semicircle waiting radius；With cutting of conductor 1
Face is corresponding, and described upper insulating part 21 and lower insulating part 12 are provided with the groove that section is semicircle, described phase insulation part 23
For planar structure.Described housing is almag housing.The width of described housing is 9～11 centimetres, the thickness of described housing
For 3～6 millimeters.Described conductor 1 adopts the conductor of isolated insulation technology processing for surface.Described conductor 1 is electrolysis copper conductor, aluminium
Conductor, aluminium alloy conductor or copper aluminum composite material conductor.
Low-voltage hollow conductor is set in this bus duct, housing is divided into upper shell 31 with lower house 32 and then to be fixedly connected,
Hollow conductor has reached maximized radiating effect by chimney type wind tunnel effect, and housing is divided into upper shell 31 and lower house 31,
Both connecting portions are superimposed naturally, form " sub- " character form structure, strengthen the mechanical strength of bus duct.In structure, this bus
Groove inner hollow conductor adopts new overall packing technology insulation close-packed arrays, the compact knot of the integral radiating of mutual closed assembly
Structure.Molding (aluminium alloy) closure not only has higher mechanical strength, and has excellent corrosion resistance and thermal diffusivity,
Can use as 100% earth conductor.This structure can efficient balance items impedance, thus greatly reduce bus duct system electricity
Crushing loses.Using hollow technology.Conductor adopts the cathode copper of high-quality, raffinal, copper aluminum composite material；Using New insulated material
Material, class of insulation b level, long-term work is to remain to keep good state of insulation in 130 DEG C of environment.Bus-bars conductor surface using every
From insulation technology technique, the industrial frequency withstand voltage that can bear 3750v lasts 1mim and no punctures and flashover.Ultrathin type, bus duct is originally
Only 10 centimetres of body width, shell, using double u-shaped structures, in evagination waterproof construction, is not only to protrude one layer of waterproof material, enters
Housing below waterproof material has been carried out thickening design by one step, and the coupling part of housing is not only thickness of shell twice, and
It is the design thicker than thickness of shell twice, embody the perfect adaptation of " mouth " font structure and " sub- " character form structure further,
Load is good, and achievable large span is horizontally mounted.Compact " sandwich " structure, using almag section bar shell, thickness reaches
