Abstract
The utility model discloses a copper aluminium composite wire clamp, including upper portion aluminium matter cylinder and lower part aluminium matter rectangular plate, cast the copper cylinder in the aluminium matter cylinder, cast the transition alloy layer between copper cylinder and aluminium matter cylinder. This is novel through casting copper cylinder in the aluminium cylinder to set up copper aluminium transition alloy layer between aluminium cylinder and copper cylinder, weakened the condition that prior art copper aluminium connects and produces the galvanic cell effect, this novel various copper aluminium composite cable clamp with present in-service use compares, has electrochemical corrosion prevention, anti-oxidation corrosion, prevents that virtual connection overflows, rain-proof snow is moist, prevent dust pollution, prevent mechanical fracture's function, in addition, the utility model discloses manufacturing process is simple, and is low with the copper volume, and installation convenient to use can effectively reduce production, use cost, is a fine substitute product of current copper aluminium transition cable clamp.
Description
Technical field
The utility model relates to a kind of joint that connects copper conductor and aluminium conductor, especially a kind of compound wire clamp of copper aluminium that is used for transformer input and output binding post and outer guide line.
Background technology
Copper-aluminium transition equipment cable clamp is widely used in being connected of copper member in the galvanic circle and aluminium element, directly is connected the generation couple corrosion to prevent copper with aluminium.In the power engineering, copper, two kinds of conductors of aluminium are owing to its good characteristic extensive application, and both connections are inevitable.But because the metal active gender gap of two kinds of metals is bigger, when directly contacting, on the contact-making surface of two kinds of conductors, be easy to form the primary cell electro-chemical reaction, by electric current the time, quicken to produce couple corrosion, further aggravate the contact-making surface degradation.Couple corrosion makes and produces nonconducting alundum (Al (Al2O3) on the contact-making surface, and this material resistance is very big, and its breakdown strength is 4000V/cm, and this will cause the contact-making surface temperature to rise rapidly, produce heating and fire incident.
Existing copper-aluminium transition wire clip mainly contains two classes, and solder type and casting connect type.Two kinds of wire clamp main bodys are aluminum integral body, are divided into two parts: anterior copper-aluminium transition joint and rear portion aluminum connecting plate.Connect dual mode by welding or casting on the copper-aluminium transition joint and connect copper part, connect copper cash, connect aluminum steel by the aluminum connecting plate simultaneously, finish copper-aluminium transition with this with copper part.Solder type often copper consumption is big, and mechanical strength is low, easily produce the crack causes corrosion, and then causes electric power accident.Casting connects method because copper aluminium directly connects, and contact-making surface constitutes the primary cell condition, and then produces the primary cell couple corrosion.Therefore, be better than welding method, in prolonged application, still occur the heating accident easily though casting connects effect.
The utility model content
The utility model technical issues that need to address provide a kind of anti-couple-corrosion, the compound wire clamp of copper aluminium that anti-oxidation burn into mechanical strength is high.
For addressing the above problem, technical solution adopted in the utility model is: the compound wire clamp of a kind of copper aluminium, comprise top aluminium matter cylinder and bottom aluminium matter rectangular slab, and be cast with copper cylinder in the aluminium matter cylinder, between copper cylinder and aluminium matter cylinder, be cast with transition alloy layer.
Be provided with threaded connection hole in the described copper cylinder.
Described copper cylinder is the copper cylinders of six ribs.
Adopt the beneficial effect that technique scheme produced to be: this is novel by cast copper matter cylinder in the aluminium cylinder, and between aluminium cylinder and copper cylinder, the copper-aluminium transition alloy-layer is set, the prior art copper-aluminium joint of having weakened produces the condition of galvanic effect, this novel compound wire clamp of various copper aluminium with actual use is at present compared, have following characteristics: owing to adopt the alloy-layer of metal active between copper aluminium is transition zone, thereby effectively weakened the primary cell extent of reaction, therefore can effectively prevent couple corrosion.Because casting technique is adopted in copper aluminium joint portion, has sealing well, make air be difficult to contact, so can effectively prevent oxide etch.Because wire clamp copper screwed hole realizes that with the transformer connection post full cylinder is connected, contact area is big, and the contact firm stable can satisfy big electric current and pass through, and effectively prevents the heating accident that the virtual connection overcurrent brings.Downward because of wire clamp screwed hole in using, copper aluminium contact-making surface top seals fully, can effectively stop sleet ponding to enter.Because the casting of copper aluminium contact-making surface connects, therefore good seal can effectively stop extraneous dust pollution.Because the wire clamp compact conformation, and adopt casting technique processing, the wire clamp mechanical strength is big, has prevented that effectively wire clamp is subjected to the destruction that external force (installation, wind and rain, variations in temperature etc.) causes and makes the wire clamp fracture.In addition, the utility model manufacturing process is simple, and copper consumption is low, and is easy to install, can effectively reduce production, use cost, is a kind of good substitute product of existing copper-aluminium transition wire clip.

Fig. 2 is a left TV structure schematic diagram of the present utility model;
Fig. 3 is a plan structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
As Figure 1-3, the utility model comprises top aluminium matter cylinder 4 and bottom aluminium matter rectangular slab 5.Be cast with copper cylinder 1 with threaded hole in the aluminium matter cylinder, screwed hole 2 is used for being connected with the transformer bolt, adopts transition alloy layer 3 castings to be connected between copper cartridge outer surface and the aluminium matter cylinder, is cast into an integral body.The metal active of its transition alloy layer 3 is higher than copper, is lower than aluminium simultaneously, and the galvanic effect that weakened plays the effect of protection aluminium contact-making surface, will reduce the couple corrosion of primary cell.The aluminum rectangular slab 5 and the forward cylinder at wire clamp rear portion are an integral body, can assemble aluminium matter wire clamp as required in actual use, or fixedly aluminium is arranged.
