The utility model has the advantages of simple structure, convenient installation, reliable capability, large current capacity range, good pressure resistance and insulating performances and high short circuit resistance strength.
Description
The utility model relates to the air-cooled close type socket joint bus of a kind of hollow, belongs to transmission facility.
At present, the used bus of power, illumination, feed in places such as skyscraper, multi storied industrial factory building, the intensive workshop of equipment, laboratory, exhibition center, old old factory rehabilitation generally adopts the plug-in type enclosed busbar.Its conductor is rectangular copper bar or aluminium row, and bus connects the employing socket connection and adds break-through bolt outsourcing insulating sleeve, the method for attachment of this plug-in type, make bus fastening, expand with heat and contract with cold, need add special-purpose expansion joint in order to eliminate, cause complex structure, be easy to cause short circuit; In addition, the line of drawing connects by spliced eye, has increased contact resistance and fault point; Also have, bus need add special-purpose reducing joint when the change cross section, because bus bar elements is more, install more loaded down with trivial details.In a word, existing its structure of plug-in type enclosed busbar awaits improving.
The purpose of this utility model is to design a kind of simple in structure, by connecting the air-cooled close type socket joint bus of hollow that inner sleeve connects.
The purpose of this utility model is to realize like this, it is mainly by tubular hollow conductor (1), insulating barrier (2), outer cover of steel plate (3), lead-out wire switch-box (5), connect inner sleeve (10), bus connects jig parts such as (11) and forms, it is characterized in that: tubular hollow conductor (1) is coated with insulating barrier (2), the two sides of insulating barrier (2) are connected with side steel plate (7), the upper and lower surface of insulating barrier (2) is connected with upper steel plate (8) and lower steel plate (9), the end of tubular hollow conductor (1) is connected jig (11) connection by connecting inner sleeve (10) with bus, bus junction (4) are provided with lead-out wire switch-box (5).
Its feature also is: lead-out wire switch-box (5) is provided with wire hole (6).
Its feature also is: the junction, termination of tubular hollow conductor (1) is provided with flexible crack (14).
Its feature also is: bus connects jig (11) and is provided with lock screw hole (12) and lead-out wire terminal screw hole (13).
The utility model is compared with prior art: it is simple in structure, easy for installation, good looking appearance, dependable performance, carry the current capacity scope big, carry electric current to can be the 100-5000 ampere, withstand voltage good insulation preformance, Short Circuit withstand intensity is big, is applicable to three-phase four-wire system, three-phase five-wire mode and various using electricity system.
Further specify below in conjunction with drawings and Examples:
Accompanying drawing 1 is the utility model broken section structural representation.
Accompanying drawing 2 is junction, the termination structural representation of tubular hollow conductor (1).
Accompanying drawing 3 is the view profile of A-A among Fig. 2.
Wherein: 1, tubular hollow conductor, 2, insulating barrier, 3, outer cover of steel plate, 4, bus junction, 5, the lead-out wire switch-box, 6, wire hole, 7, side steel plate, 8, upper steel plate, 9, lower steel plate, 10, connect inner sleeve, 11, bus connects jig, 12, lock screw hole, 13, lead-out wire terminal screw hole, 14, flexible crack.
From accompanying drawing as can be seen: the utility model it mainly by tubular hollow conductor 1, insulating barrier 2, outer cover of steel plate 3, lead-out wire switch-box 5, connect inner sleeve 10, bus connects jig 11 parts such as grade and forms, among the described tubular hollow conductor 1 present embodiment figure is 4, also can be 5 tubular hollow conductor 1, tubular hollow conductor 1 is coated with insulating barrier 2, the length of the described insulating barrier that wears 2 visual tubular hollow conductor assembles by polylith is parallel, the distance that every insulating barrier of present embodiment is 2 is 250mm, the insulating barrier 2 outer outer cover of steel plate 3 that are provided with, the two sides that are insulating barrier 2 are connected with side steel plate 7, and the upper and lower surface of insulating barrier 2 is connected with upper steel plate 8 and lower steel plate 9; The end of tubular hollow conductor 1 is connected jig 11 and connects by connecting inner sleeve 10 with bus, the junction, termination of tubular hollow conductor 1 is provided with flexible crack 14, like this, when running into when expanding with heat and contract with cold, need not to add special-purpose expansion joint, can self adjusting; Bus connects jig 11 and is provided with lock screw hole 12 and lead-out wire terminal screw hole 13, locking by lock screw hole 12, can make the end of two tubular hollow conductor 1 connect more firmly, bus junction 4 also is provided with lead-out wire switch-box 5, lead-out wire switch-box 5 is provided with wire hole 6, uses in order to external line.
