Abstract
The invention discloses a laminated silver-copper-brazing-filler-metal three-composite electrical contact material manufactured by a coating and sleeving method and a manufacturing method thereof. Silver-alloy powder and copper-alloy powder are manufactured by using an atomization method or a powder mixing method; the silver-alloy powder and the copper-alloy powder are manufactured into a silver-alloy/copper-alloy band material; and then compounding is carried out on the silver-alloy/copper-alloy band material and a brazing filler metal to obtain a three-composite electrical contact material. Therefore, an electrical contact material having advantages of low material costs, excellent integrated electrical performances, silver saving and environmental protection is provided to replace the traditional copper-alloy contact material, silver-alloy contact material, and silver-copper-alloy contact material.
Description

Relay, catalyst, the core parts of chopper are electrical contact (point), and it carries connects the heavy of breaking current
Task, the quality of contact elements depends on the performance of electrical contact (point) material and scientific and effective combination, and it is security appliance
Important guarantee.
At present, the contact material that on market, usage amount is maximum is silver alloy and the big class of copper alloy two.Copper alloy contact material
Certain applications are on chopper and high-voltage switch gear, although copper alloy contact material is cheap, but copper alloy electric contact antioxidation
Poor performance, different in size to the commercial time after installation, when electrical equipment shelves time length, use, electrical contact surface can form oxidation
Film, disjunction can discharge substantial amounts of heat the most in use, will also result in surface and is generated oxide-film by thermal oxide, makes contact resistance increase
Affect electric conductivity and heat conductivity greatly, make the temperature rise of electrical equipment increase；Increasing of switch temperature rise, all components and parts in meeting acceleration switch
Lost efficacy, shortened its electric life.Therefore vicious cycle occurs, makes electrical equipment cross heat-induced damage and occur that contact melted leads to safe thing
Therefore.
Existing silver alloy contact material is widely used on relay, catalyst, chopper.Wherein, silver tungsten and silver carbonization
Tungsten graphite is used in the typical material on chopper.
The most general miniature circuit breaker uses Agcdo or silver graphite alloy (such as AgC4) contact material etc..But it contains
Silver amount is the highest, and the silver content of silver cadmium oxide contact material is all more than 85%, and is the main flow product in current contact material market
Product, annual consumption silver amount is the hugest.But silver resource is very limited of today, along with the increase of consumption, will cause silver
Rapid rise of price, so that the cost producing electrical contact material remains high, Business Economic Benefit declines, and social benefit is the most greatly cut
Subtract.And another metallic element cadmium environmental pollution of this series products is relatively big, does not meets the development trend of nowadays environmental protection.Therefore,
Appliance manufacturers is on the premise of ensureing quality, it is desirable to alloy industry uses base metal to replace noble silver to lower product
