Description
Technical field
The present invention relates to electric power T & D Technology field, specifically a kind of pipe method for connecting bus.
Background technology
Existingly for managing the technology that bus connects, mainly contain two classes, one class is to adopt the outer formula of pressing, the link at pipe bus is provided with 4 breaches, inner sleeve directly embeds pipe bus link, on pipe bus link cylindrical, with anchor ear, hold and lock bolt tightly again, there is profile out-of-flatness, unbecoming, follow-up construction trouble and consume material in the method many, the limitation that cost is high; Another kind of is on the basis of above-mentioned method of attachment, it is closely connected the welding of pipe bus link breach with inner sleeve after, again anchor ear is removed, the method has overcome the defect that in said method, profile is smooth, unbecoming, consumption material is many, cost is high, but exist, press the limitation that degree is poor, tensile strength is low, conductive effect is poor, particularly, in large electric current transmission of electricity process, electronic vibration easily causes the loosening distortion in junction, thereby causes coming off, disconnecting of pipe bus and connector.
Publication number is CN101615729, within open day, be on December 30th, 2009 Patent Application Publication a kind of pipe bus connector, this connector is set in pipe bus connecting portion by perisporium being provided with to the conductive sleeve of axially open, and adopts the scolder welding identical with pipe bus-bars conductor material that copper busbar connecting portion and conductive sleeve are closely connected as a single entity at opening part.This connector has overcome the easily limitation of loosening distortion of large current delivery process to a certain extent, but still has the defect that junction contact is poor, tensile strength is low, conductive effect is not good enough.
Publication number is CN101043104, within open day, be on 09 26th, 2007 Patent Application Publication a kind of tube bus connector, this tube bus connector is by copper, aluminium, the end of copper composite pipe bus adopts anchor ear, metallic sheath or with curved metal pressing plate by bolt by soft copper, thereby aluminium strip is directly fastened on formation tube bus connector on end of bus bars, the soft copper of tube bus connector, aluminium strip is connected with miscellaneous equipment terminal again, because this tube bus connector is directly by soft copper, aluminium strip is fastened on and on end of bus bars, forms integrative-structure, there is no connection bit, there is no contact resistance, reduce caloric value, ampacity is large, the end that guarantees bus can not produce high temperature, safe operation.But this tube bus connector exist equally outward appearance out-of-flatness, unbecoming, consume the limitation that material is many, cost is higher.
Publication number is CN101540441, within open day, be on September 23rd, 2009 Patent Application Publication a kind of tubular bus connector, this tubular bus connector includes the middle conductor of one section of tubular, two sections of the front and back of middle conductor inwall are respectively arranged with the internal conical surface that outer end diameter is larger, two sections of internal conical surface inner sides, be respectively arranged with the inner conical drogue matching with it, the endoporus of inner conical drogue is the circular hole matching with tubular bus external diameter, the outer wall of inner conical drogue has the outer conical surface matching with internal conical surface in above-mentioned middle conductor, on the barrel of inner conical drogue, also have a slit axially connecting, at middle conductor two ends, be respectively arranged with end cap, between end cap and middle conductor, by threaded engagement, be connected, the inner side of end cap is pressed on the outside end face of inner conical drogue.This connector smooth-shaped is refined, conductive contact surfaces is large, contact is large, there is higher connection reliability, but still exist, connect firm not, the undesirable limitation of tensile strength, when it is in order to improve fastness and the pull resistance of connection, certainly will strengthen two ends end cap and to centre, press promotion inner conical drogue to middle displacement, now easily make intervalve bus be out of shape and reduce electric conductivity.
Summary of the invention
