Abstract
The utility model relates to an ultra-long dense insulated bus groove, which is used for electric power distribution. The ultra-long dense insulated bus groove comprises a metal housing (1) and a conductive rows (3) which are coated by insulated material (2). The utility model is characterized in that the conductive rows (3) are longitudinally ranged in the metal housing (1) at regular intervals, and bolts (4) which fix the conductive rows (3) in the metal housing (1) are arranged among the conductive rows (3). The bus groove of the utility model solves the difficult problem of sagging of the ultra-long bus groove by the method that the conductive rows (3) are longitudinally ranged in the metal housing (1), and the utility model has the characteristics of good radiating performance and high short-circuit intensity.
Description
Technical field
The utility model relates to a kind of bus duct that is used for the intensive insulation of overlength of electrical power distribution.
Technical background
Bus duct is to be made of the busbar and the metal shell of isolating with insulating material.Bus duct can be divided into according to the insulation mode of busbar: bus ducts such as intensive insulation, air insulation, double insulation.The busbar of intensive isolated bus groove laterally is set up in parallel in metal shell after isolating with insulating material, and is close together with shell, and as shown in Figure 2, its heat dispersion will be got well than other bus duct, so its scope of application is the widest.Because bus duct single-unit length is generally 3 meters, when the bus duct level was installed, every joint bus duct must have two supports to be fixed.When the wall level is installed, it is not difficult to add two supports on the wall, if but on relatively large factory building, airport etc. when large-scale occasion level is installed, support can only be installed on the pillar, and the spacing of an intercolumniation is often greater than 3 meters, that have even reach 9 meters, this brings difficulty for the installation of bus duct, even it is 9 meters that the length of single-unit bus duct is done length, but the structure of existing intensive isolated bus groove and the deadweight of bus duct will cause bus duct sagging, make the connector of bus duct produce displacement cause connecting unreliable.The existing sagging method of bus duct that solves has two kinds: the one, and hanging with cable wire that bus duct makes it can not be sagging, just can't realize but run into when there is obstacle the bus duct top; Another kind method is thickening bus duct shell or the shape (for example making corrugated) that changes shell, and this method can reduce the sagging of bus duct, but is not an effective method.
Summary of the invention
The utility model has overcome the sagging defective of the intensive isolated bus groove of existing overlength, provide a kind of novel overlength intensive isolated bus groove, this bus duct is vertically arranged busbar and is placed in the metal shell, solved the sagging difficult problem of overlength bus duct, and had the advantages that heat dispersion is excellent, short-circuit strength is high.
The utility model is achieved in that the intensive isolated bus groove of a kind of overlength, the busbar that comprises metal shell, insulating material looping, it is characterized in that each busbar segment distance of being separated by vertically is arranged in the metal shell, is equipped with bolt busbar is fixed in the metal shell between busbar and busbar.
Operation principle of the present utility model is to adopt vertical arrangement of every busbar placed the metal shell inner structure, utilize I-beam load-bearing principle, regard every busbar as I-beam, the five-wire system bus duct is equivalent to five I-beams and vertically makes up, and five busbars and metal shell are tightened the composition one by bolt, thereby make the intensive isolated bus truss of overlength be located at sag engineering demands on the support.Because every busbar all is close to metal shell, so the more existing bus duct of the heat dispersion of bus duct is superior, the Short Circuit withstand strength capabilities is strong.
Description of drawings
Fig. 1 is the structural representation of the intensive isolated bus groove of the utility model overlength, and Fig. 2 is the structural representation of existing intensive isolated bus groove.
Among the figure: 1 metal shell, 2 insulating material, 3 busbars, 4 bolts.
Execution mode
Referring to Fig. 1, the intensive isolated bus groove of a kind of overlength, the busbar 3 that comprises metal shell 1, insulating material 2 loopings, each busbar 3 segment distance of being separated by vertically is arranged in the metal shell 1, the leptoprosopy that is busbar 3 is relative with leptoprosopy, the wide face of busbar 3 is close on the metal shell, bolt 4 is housed between busbar 3 and busbar 3 busbar 3 is fixed in the metal shell 1, and whole bus duct is formed one.The transversely arranged bus duct of bus ducts that this busbar 3 is vertically arranged and busbar is compared, and has extremely strong anti-sagging ability, so is applicable to the distribution in big span place; The Short Circuit withstand strength capabilities is strong in addition, perfect heat-dissipating.
Claims (1)
1. intensive isolated bus groove of overlength, the busbar (3) that comprises metal shell (1), insulating material (2) looping, it is characterized in that each busbar (3) segment distance of being separated by vertically is arranged in the metal shell (1), is equipped with bolt (4) busbar (3) is fixed in the metal shell (1) between busbar (3) and busbar (3).
