Description

Pipe bus tapered connection device

Technical field

The utility model relates to electric power power transmission and transformation technical field, specifically a kind of pipe bus tapered connection device.

Background technology

Existing be used to manage the technology that bus connects and mainly contain two types; One type is to adopt the outer formula of pressing; Promptly the link at the pipe bus is provided with 4 breaches, and inner sleeve directly embeds pipe bus link, on pipe bus link cylindrical, holds and lock bolt tightly with anchor ear again; This method exists profile out-of-flatness, unbecoming, follow-up construction trouble and consumes material many, the limitation that cost is high; Another kind of is on the basis of above-mentioned method of attachment; To manage after bus link breach welding closely fuses its and inner sleeve, and anchor ear removed again, this method has overcome smooth, unbecoming, many, the defect of high cost of consumption material of profile in the said method; Degree is poor, tensile strength is low, the limitation of conductive effect difference but existence is pressed; Particularly in big electric current transmission of electricity process, electronic vibration is prone to cause the loosening distortion in junction, thereby causes coming off, breaking off of pipe bus and connector.

Publication number is CN101615729; The patent application that open day is on December 30th, 2009 discloses a kind of pipe bus connector; This connector is set in pipe bus connecting portion through the conductive sleeve that perisporium is provided with axially open, and adopts the scolder welding identical with pipe bus-bars conductor material to make copper busbar connecting portion and conductive sleeve closely be connected as a single entity at opening part.This connector has overcome the limitation that big current delivery process is prone to loosening distortion to a certain extent, but still has the defective that the junction contact is poor, tensile strength is low, conductive effect is not good enough.

Publication number is CN101043104, open day is that on 09 26th, 2007 patent application discloses a kind of tube bus connector, thereby this tube bus connector adopts the end of copper, aluminium, copper composite pipe bus anchor ear, metallic sheath or through bolt soft copper, aluminium strip directly is fastened on formation tube bus connector on the bus end with the curved metal pressing plate; The soft copper of tube bus connector, aluminium strip are connected with the miscellaneous equipment terminal again; Because this tube bus connector is directly soft copper, aluminium strip to be fastened on the bus end to be integrally formed structure, do not connect the position, there is not contact resistance; Reduce caloric value; Ampacity is big, guarantees that the end of bus can not produce high temperature, safe operation.But this tube bus connector exists outward appearance out-of-flatness, unbecoming, the consumption limitation that material is many, cost is higher equally.

Publication number is CN101540441; The patent application that open day is on September 23rd, 2009 discloses a kind of tubular bus connector; This tubular bus connector includes the middle conductor of one section tubular; The front and back of middle conductor inwall are respectively arranged with the bigger internal conical surface of outer end diameter for two sections, are respectively arranged with the inner conical drogue that matches with it two sections internal conical surface inboards, and the endoporus of inner conical drogue is the circular hole that matches with the tubular bus external diameter; The outer wall of inner conical drogue have with above-mentioned middle conductor on the outer conical surface that matches of internal conical surface, on the barrel of inner conical drogue, also have a slit that axially connects; Be respectively arranged with end cap at the middle conductor two ends, be connected through threaded engagement between end cap and the middle conductor, the inboard of end cap is pressed on the outside end face of inner conical drogue.This connector smooth-shaped is refined, conductive contact surfaces is big, contact pressure is big; Has higher connection reliability; Connect firm inadequately, the unfavorable limitation of tensile strength but still exist; When its fastness and pull resistance in order to improve connection, certainly will strengthen the two ends end cap and press the promotion inner conical drogue to middle displacement to the centre, make the distortion of intervalve bus this moment easily and reduce electric conductivity.
