Embodiment
The present invention is described in further details with reference to the accompanying drawings and detailed description.
Referring to Fig. 2 and 4, the embodiment of the present invention additionally provides a kind of new isolated-phase enclosed bus, and it includes shell 1 and led
Body 2, conductor 2 be located at the inside of shell 1 and between it is spaced.In a tubular form, conductor 2 can be set shell 1 by supports insulative 3
Inside shell 1.Kelvin effect when being transmitted due to electric current, conductor 2 is in a tubular form.In order to reduce production cost, shell 1 and conductor
2 material is preferably all aluminium.The quantity of the inner wire 2 of shell 1 is one.
Referring to Fig. 1, the embodiments of the invention provide a kind of conductor of new isolated-phase enclosed bus, it is spiral weld gold
Category pipe (or spiral welded pipe), the conductor of isolated-phase enclosed bus shown in Fig. 2 is the conductor shown in Fig. 1, and the conductor is spiral weld
Metal tube, the shell of isolated-phase enclosed bus shown in Fig. 2 is non-helical welded tube, i.e., the metal tube manufactured using prior art.Referring to
Fig. 3, the embodiments of the invention provide a kind of shell of new isolated-phase enclosed bus, it is spiral weld metal tube (or spiral shell
Revolve welded tube), the shell of isolated-phase enclosed bus shown in Fig. 4 is the shell shown in Fig. 3, and the shell is spiral weld metal tube, Fig. 4 institutes
The conductor for showing isolated-phase enclosed bus is non-helical welded tube, i.e., the metal tube manufactured using prior art.Preferably, it is new from phase
The conductor and shell of enclosed busbar are spiral weld metal tube.
During manufacture, shell 1 or conductor 2 are that, using strip metal roll bending as raw material, frequent warm rolling is molded, form helical form
Pipe seam, then pipe seam is welded and is made with forming spiral weld 11,21.Due to using spiral weld metal tube, phase
Than in prior art：The small short section of cylinder is generally rolled into using aluminium sheet, about 1 meter~3 meters, diameter more long length is shorter, so
The aluminum barrel of these short sections is spliced into longer aluminum barrel again afterwards so that narrower blank, i.e. band (coiled material) blank can be used, it is raw
The larger shell of caliber is produced, the different shell of caliber can also be produced with the blank of same width, while compared with ERW, its is strong
Degree increases.During fabrication, it is to be welded when rolling, circularity is preferably corrected without the later stage, and size adjusting is convenient, speed of production
Hurry up, efficiency high, good product quality, precision be high, saves material, saves artificial.The aluminum barrel of short section is spliced into longer in the prior art
Aluminum barrel when, by the way that the weld seam of circumferencial direction is welded together between adjacent short section, and the weld seam of circumferencial direction is leads
Electric section, therefore welding quality proposes that requirements at the higher level, complex process, and quality are difficult to control to.Using spiral weld metal tube,
The weld seam quantity of circumferencial direction can be reduced, manufacture difficulty is reduced.Only the longitudinal joint of equivalents, eliminates circumferential weld, therefore lead
Electric energy power is only determined in itself by base material, is no longer influenced by the influence of weld seam conductive capability.
In order to reduce fusion length, the conductive effect of conductor 2 is improved, conductor 2 is by one section of metal tubular into as integral type
Structure.The rotation direction of the spiral weld 21 of conductor 2 can be dextrorotation or left-handed.Likewise, shell 1 also by one section of metal tubular into,
As integral structure.The rotation direction of the spiral weld 11 of shell 1 can be dextrorotation or left-handed.It is preferred that the spiral of shell 1 and conductor 2
The rotation direction of weld seam is identical, and strip width used is identical.
It is multistage metal tube, as split-type structural by 2 points of conductor to adapt to the connection distance between distinct device,
Multistage metal tube is produced during production, every section of metal tube is spiral weld metal welded tube, then by being sequentially connected multistage metal
Pipe assembles to form conductor 2.Likewise, be multistage metal tube by 1 point of shell, as split-type structural produces multistage during production
Metal tube, every section of metal tube is spiral weld metal welded tube, then assembles to form shell 1 by being sequentially connected multistage metal tube.
It is preferred that the two ends of adjacent both ends metal tube are welded to connect to be welded to connect, that is to say girth welding, so make by connected mode
It must manufacture and install simple and convenient, in other examples, can also be connected by flange, the present embodiment is not limited this
It is fixed.The rotation direction of every section of metal tube can be with identical, can also be different, and the rotation direction that the spiral weld 21 of conductor 2 is allow when identical is
Dextrorotation is left-handed.For spiral weld metal tube conductor spiral weld on conductor axial direction spacing can with for spiral weld gold
The spiral weld for belonging to the shell of pipe is equal in the upward spacing of enclosure axis.
In order to reduce the production difficulty of conductor 2 and the production cost of shell 1 and reduction conductor 2 and shell 1, conductor 2 and shell 1
Material be preferably all aluminium, in other examples, the material of conductor 2 and shell 1 can also select copper.
In summary, beneficial effects of the present invention are as follows：
Speed of production is fast, efficiency high；Save material, save artificial；Good product quality, precision are high；Only equivalents
Longitudinal joint, eliminates circumferential weld, therefore conductive capability is only determined in itself by base material, is no longer influenced by the influence of weld seam conductive capability.
As known by the technical knowledge, the present invention can be by the embodiment party of other essence or essential feature without departing from its spirit
Case is realized.Therefore, embodiment disclosed above, for each side, is all merely illustrative, and is not only.Institute
Have within the scope of the present invention or be included in the invention in the change being equal in the scope of the present invention.
