Abstract

The utility model discloses a copper aluminum compound conductive rod which belongs to high voltage apparatus components. The conductive rod is composed of a conductive end and a contact end; the contact end has two kinds of symmetry and non-symmetry; the middle part is a conductive end; a pure aluminum is adopted as a transition end for the contact end and the conductive end to improve stability of welding. The contact end for the invention adopts an industrial pure copper-purple copper rod with good conductive performance, higher melting point, excellent hot stability and higher hardness and wear proof performance; the non-contact end adopts aluminum or alloy aluminum with slightly bigger resistance rate, small density and low price; the gravity of the aluminum is only a third of copper and price is 57% of the copper, which is very useful for lowering cost and decreasing weight of equipment; mainly through increasing wall thickness of the conductive pipe part but not increasing the outer diameter size, conductive performance of the conductive rod can reach the level of the conductive rod for pure copper.

Description

Copper-aluminum composite conductive pole

Technical field

Utility model belongs to the High-Voltage Electrical Appliances components range, particularly a kind of copper-aluminum composite conductive pole.

Background technology

In the circuit breaker of the above electric pressure of 10KV, the combined electrical apparatus high-tension electricity devices such as (GIS), be used for the conductor of connection, conduction current between the element, be called conducting rod.The electric current that conducting rod passes through is 400-4000A, is made by red copper bar or copper tube usually.Conventional conductive bar material is red copper bar or copper tube, and weight is heavier, and the price height causes the device fabrication cost to increase.

Summary of the invention

The purpose of this utility model is to be red copper bar or copper tube at conventional conductive bar material in the above-mentioned prior art, and weight is heavier, and the price height causes the deficiency that the device fabrication cost increases and a kind of copper-aluminum composite conductive pole is provided.It is characterized in that: described conducting rod is made up of conducting end and contact jaw two parts, and the part that connects mutually with the fingertip element is called contact jaw, is divided into two big classes, and a class is a symmetrical structure, and a class is a unsymmetric structure; The two ends of symmetrical structure are contact jaw 1, and the middle part is a conducting end 3, in conducting end seal groove 7 is set; One end of unsymmetric structure is that contact jaw 1, one end is a conducting end 3, is connected by transitioning end 2 between contact jaw 1 and the conducting end 3, and the contact-making surface 4 of its conducting end 3 and transitioning end 2 is the plane, and the contact-making surface of contact jaw 1 and transitioning end 2 is a taper seat 5.

Described conducting end is hollow pipe or solid bar.

The contact-making surface of described conducting end and transitioning end is plane or step contact-making surface.

Described contact jaw is a red copper bar.

The conducting end of described unsymmetric structure conducting rod makes screw thread or cone.

The beneficial effects of the utility model are that this product is made up of conducting end and contact jaw two parts.Contact jaw adopts that electric conductivity is good, fusing point is higher, thermal stability is good, hardness and the higher industrial pure copper of anti-wear performance---red copper bar, possesses the ability of certain are-tight scaling loss, can realize movably contacting with the fingertip element; Conducting end does not generally movably contact with other element, adopts big slightly and little, cheap aluminium or the alloy aluminum manufacturing of density of resistivity.

The proportion of aluminium only is 1/3 of copper, price is the 40-50% of copper, help reducing cost greatly, alleviate weight of equipment, by increasing the conducting rod sectional area, promptly strengthen the wall thickness at conducting end pipe position, can reduce conducting rod resistance,, the resistance of copper aluminium composite conducting bar can be controlled to the level of fine copper conducting rod by designing and calculating, generally needn't strengthen under the situation of overall dimension of conducting rod, make the conducting rod of making reach the instructions for use of High-Voltage Electrical Appliances.
