Abstract
The present invention relates to a special alloy electric contact material for low-voltage electric appliances, which has the composition ratio (weight percentage) of 0.1% to 3% of C, 0.5% to 5% of vanadium carbide, 0.5% to 10% of niobium carbide; 0.5% to 5% of zirconium oxide; 0.01% to 1% of lanthanum oxide; 0.1% to 1% of tellurium, 0.5% to 5% of plumbum and 0.1% to 1% of selenium, and the rest is copper. The alloy contact material has the advantages of good electric conductivity and thermal conductivity, high electri arc burning and welding resistance and favorable oxidation resistance and combination properties, and can be used for the low-voltage electric appliances instead of a silver alloy contact material.
Description
The invention belongs to a kind of electrical contact material, particularly a kind of electric special alloy contact material for low-voltage electric appliance.
Low-voltage electrical apparatus is a kind of electrical equipment that is of wide application, and its electrical contact then is one of key element of low-voltage electrical apparatus, and its effect is to connect and breaking current.Electrical contact material adopts the silver-base alloy of series such as Ag-Ni, Ag-CdO, Ag-SnO mostly at present, so traditional a large amount of precious metals silver of electrical contact consumption.Therefore, research and applied cost are cheap, and the no silver alloy electrical contact material of dependable performance is significant.For guaranteeing the low-voltage electrical apparatus reliability during operation, electrical contact material must have good electrical conductivity, thermal conductivity, anti-electrical arc erosion and resistance fusion welding, also must have good antioxygenic property simultaneously.For satisfying above-mentioned performance requirement, the novel alloy electrical contact material must be the following a kind of composite material of composition: add a certain amount of high-melting-point in the metallic copper matrix with good heat-conductivity conducting performance, the carbide of high rigidity, oxide are to increase the anti-electrical arc erosion of alloy, the ability of anti-melting welding also will add the non-oxidizability that alloying elements or compound make contact material have certain arc extinguishing ability and improve alloy contact material in addition.
The purpose of this invention is to provide the special alloy electrical contact material that a kind of low-voltage electrical apparatus is used, this kind alloy contact material has good electrical conductivity, thermal conductivity, anti-electrical arc erosion and resistance fusion welding, this alloy material also has excellent non-oxidizability and combination property simultaneously, replaces the silver alloy contact material in low-voltage electrical apparatus.
Electric special alloy contact material for low-voltage electric appliance provided by the invention is characterized in that: proportioning components is (percentage by weight): carbon 0.1-3; Vanadium carbide 0.5-5; Niobium carbide 0.5-10; Zirconia 0.5-5; Lanthana 0.01-1; Tellurium 0.1-1; Plumbous 0.5-5; Selenium 0.1-1; Copper surplus.
In alloy, add carbon, can improve the anti-electrical arc erosion and the resistance fusion welding of alloy electrical contact.
The carbide that adds high-melting-point high rigidity such as vanadium carbide, niobium carbide in alloy can increase the anti-electrical arc erosion and the resistance fusion welding of alloy electrical contact, when particularly these carbide and carbon add alloy simultaneously, can increase the electric life of alloy electrical contact.
In alloy, add zirconia, lanthana and can increase the arc extinction performance and the resistance fusion welding of alloy electrical contact.
In alloy, add tellurium, selenium, lead, can increase the arc extinction performance of alloy electrical contact.
The advantage of alloy contact material provided by the invention is: have excellent conducting performance, heat conductivility, anti-electrical arc erosion performance and resistance fusion welding, have excellent non-oxidizability and excellent comprehensive performance simultaneously, can replace the silver alloy contact material in the low-voltage electrical apparatus, reduce cost.
