Description
Technical field
The utility model relates to electric power power transmission and transformation technical field, specifically a kind of hot tightening tube bus connecting 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 itself and inner sleeve; Again anchor ear is removed; This method overcome profile out-of-flatness in the said method, unbecoming, consume many, the defect of high cost of material, press that degree is poor, tensile strength is low, the limitation of conductive effect difference but exist, particularly in electric current transmission of electricity process greatly; 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 CN101043104A, 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.
Summary of the invention
For overcoming the limitation of prior art; The purpose of the utility model provides a kind of pipe bus connecting device, and this device adopts the close and firm between the heat deflation technology realization pipe bus to connect and has the advantage that the face contact is good, electric conductivity is good, tensile strength is high, profile is refined and cost is low.
To achieve these goals; The utility model adopts following technical scheme: a kind of hot tightening tube bus connecting device; Include pipe bus and inner sleeve; It is characterized in that: said pipe bus is identical material with said inner sleeve; Said pipe bus socket contact jaw (5) internal diameter is slightly littler than the external diameter that inner sleeve embeds link (6), and the socket contact jaw of said pipe bus and inner sleeve embed link and adopt heat to tighten technology to embed socket, makes between pipe bus and inner sleeve close and firm socket and face combines evenly, the face contact is good.
Preferably, insert depth is 50～180mm between the embedding link of said pipe bus socket contact jaw and said inner sleeve.
Preferably, said pipe bus socket contact jaw internal diameter embeds the little 0.10～0.20mm of external diameter of link than inner sleeve.
Preferably, contact-making surface and inner sleeve embedding outer contacting face is handled through uniform polish in the socket of said pipe bus.
Adopt technique scheme compared with prior art; Because the utility model adopts heat to tighten technology; Utilize principle of expanding with heat and contracting with cold; To manage bus socket contact jaw earlier and place under 400～500 ℃ the temperature conditions and add thermal expansion, thereby it is inner to make under the normal temperature that external diameter can be embedded into the pipe bus easily than the big slightly inner sleeve of pipe bus internal diameter, and accomplish embed socket after; Pipe bus socket contact jaw temperature is got back to room temperature gradually, makes pipe bus close and firm be socketed on the inner sleeve embedding link thereby form shrinkage; Wherein, Because pipe bus socket contact jaw partly places incubator outside when heating; Therefore when the heating-up temperature degree is lower than 400 ℃, reach the embeddable degree of inner sleeve that is expanded to thereby can't make pipe bus socket contact jaw be heated to 400～500 ℃ because heat radiation is too fast, and when heating-up temperature surpasses 500 ℃; The pipe bus is prone to oxidation and reduces its electric conductivity greatly, and makes pipe bus cracking, distortion easily; And pipe bus socket contact jaw temperature in incubator steadily rose to 400～500 ℃ from room temperature in 25～35 minute period makes pipe bus socket contact jaw metal material not receive to reach the required expansion requirement of socket fast under impression destruction, the situation indeformable, not oxidation deterioration; In addition, will manage in the bus contact-making surface and inner sleeve outer contacting mirror polish handle make combine evenly after the socket, the face contact is good, conduction is good, electronic vibration is not generated heat, do not taken place to the transmission of electricity process; Once more, the utility model device need not adopt anchor ear to connect, and has the advantage that outward appearance shape is refined, cost is low.
