Abstract
This is a contactor for low voltage electric facilities with low content or none of silver. The making material includes 0.05-20% CeO2 or La2O3, copper, 0.05-15% silver or fine diamond powder.
Description
Technical field
The present invention relates to a kind of low-voltage electrical apparatus electrical contact material, particularly a kind of low-voltage electrical apparatus electrical contact material of few Yin Jieyin type.
Background technology
All adopt Pd-Ag substrate alloy material as electrical contact material in traditional low-voltage electrical apparatus, these Ag-based electrical contact materials cost an arm and a leg, and all will consume a large amount of noble metal silvers every year.
In recent years, domesticly invented a kind of electric contact material of copper-based alloy, representing patent is " copper base low-voltage electrical apparatus electrician contact alloy material " patent No. (94102452.0).This copper based no silver contact material is to add cadmium (Cd) and diadust in the copper matrix, and this contact material has excellent resistance fusion welding and anti-electrical arc erosion performance, and price is low.Use in the part low-voltage electrical apparatus at home, obtained result of use preferably.But also exist shortcoming on this copper-based non-silver contact serviceability: 1) the arcing molten bath of contact surface causes contact surface rough and uneven in surface more greatly after the arcing.2) when the big arcing rear section of diamond addition Buddha's warrior attendant graphitization, remain in contact surface, have influence on the contact resistance of contact.These shortcomings can cause the low-voltage electrical apparatus that uses this contact too high in break-make and electric life form test back temperature rise, have influence on the particularly use on A.C. contactor in low-voltage electrical apparatus of copper-based non-silver contact.Also contain the harmful element cadmium in the copper-based non-silver contact.
Summary of the invention
The objective of the invention is to propose a kind of silver-economizing low-voltage electrical-appliance contact materials, this electrical contact material only contains the oxidation and corrosion ability that a spot of silver increases copper, resistance fusion welding and arc ablation resistance ability all are better than copper based no silver contact material, can reduce the temperature rise afterwards of electrical contact significantly, and low price, can in low voltage electrical apparatus industry, replace the silver-base alloy contact material comprehensively.
The composition proportion that the present invention proposes a kind of few Yin Jieyin type electrical contact material is (percentage by weight):
Ceria or lanthanum sesquioxide 0.05-20%
Copper surplus
On the composition proportion basis of above-mentioned material, also can add following at least a composition (percentage by weight):
Diadust 0.05-5%
Silver 0.05-15%
In copper alloy matrix, add lanthanum sesquioxide or the ceria molecule that disperse distributes, can make alloy contact have the excellent anti-melting welding ability and the ability of arc resistant scaling loss.Rare earth element can also cause the electric arc arc root instability of contact surface when the combustion fox, shift out contact surface very soon, thereby shorten the arcing time, the material that reduces contact surface splashes, reduce the molten bath area, the integrality of contact surface after the assurance arcing, these effects all can reduce the back temperature rise of making of contact significantly.
In electrical contact material, add a spot of diadust and combine the resistance fusion welding and the anti-electrical arc erosion ability that can further improve contact material with rare earth oxide.In copper alloy, add the anti-oxidant and corrosion resistance that noble metal silver can improve alloy monolithic, reduce the degree of oxidation of electrical contact material in atmosphere, further reduce the temperature rise afterwards of electrical contact material.
The manufacturing process of silver-economizing low-voltage electrical-appliance contact materials:
1, mix---various material powders composition proportion is on request mixed;
2, moulding---the powder compression molding under the pressure of 300MPA that mixes;
The pressed compact of 3, sintering---compression moulding is come out of the stove in the cooling in 2 hours of 900 ℃ of sintering under protective atmosphere or in the vacuum.
4, hot working---the pressed compact behind the sintering is at 100mpa800 ℃ of following thermo forming.
5, rolling---be rolled into the thickness of requirement.
6, blanking forming---mould blanking forming is processed into the shape of requirement.
Advantage of the present invention is: this electrical contact material only contains a spot of silver even does not have the oxidation and corrosion ability that silver increases copper, resistance fusion welding and arc ablation resistance ability all are better than copper based no silver contact material, can reduce the temperature rise afterwards of electrical contact significantly, and low price, can in low voltage electrical apparatus industry, replace the silver-base alloy contact material comprehensively.
