Ukuze uthintele ukuvutha koqhagamshelwano lwesilivere, i-terminal yoqhagamshelwano olumileyo ibe yimo egobileyo, indawo ephakathi ephumayo.Ngoko i-arc ayiyi kumphezulu woqhagamshelwano wokutsha.Luhlobo lwefomu yoqhagamshelwano olungcono, kwaye ukusetyenziswa kwayo kuyanda.Inkqubo yokusebenza yoqhagamshelwano lomnxibelelwano ibeka phambili inani leemfuno zezinto.Ngenxa yokuba ubhedu lune-conductivity elungileyo yombane kunye ne-thermal conductivity.Ukuqina okwaneleyo.Iqondo eliphezulu lokunyibilika, ukusetyenzwa lula.Ke isetyenziswa ngokubanzi njengenxalenye yonxibelelwano yoqhagamshelwano lwe-high-voltage breaker circuit.Kodwa ngesandla sobhedu i-oxidized ngokulula, i-oxidation yokumelana noqhagamshelwano.Ke kwezinye izaphuli zesekethe, ubhedu lugqume umaleko wesilivere ngaphandle konxibelelwano oluphambili.

Isilivere ine-conductivity enhle, ifilimu ye-oxide iyaqhuba, inokuphucula ukusebenza koqhagamshelwano lobhedu lwesilivere.Ngokusetyenziswa rhoqo kwe-breaker circuit, i-silver contact arc effect thermal yanda kakhulu, indawo yoqhagamshelwano inokuba yilahleko enkulu, ngoko ke ukuchasana nobushushu besilivere, ukuchasana nokumelana ne-arc, ukuxhathisa kwe-abrasion kunye nokubeka phambili iimfuno eziphezulu.Indlela ye-powder metallurgy ivule indlela entsha yokuphuhliswa kwezinto zoqhagamshelwano.

I-metallurgy yomgubo endaweni yokusebenzisa indlela eqhelekileyo yesinyithi, kodwa iindidi ezimbini zomgubo wesinyithi zixutywe kunye kubumba olucinezelayo.Kwigesi ekhuselayo (i-hydrogen) kwinkqubo ye-sintering.Olu hlobo lwegolide ngokwenene ngumxube we-Taiwan.Ngenxa yokuba inkqubo ifana nemveliso ye-ceramic, ikwabizwa ngokuba yi-mold alloy.I-high-voltage breaker circuit breaker isetyenziswa ngokubanzi nge-tungsten yobhedu, i-nickel yesilivere, isilivere, igraphite njengokumelana noqhagamshelwano kwi-arc okanye i-arc resistance.Isetyenziswe kwii-relays, abafowunelwa, ukutshintshwa komoya, ukutshintshela umda wokuhamba, umkhuseli wemoto, ukutshintshwa kwe-micro, i-instrumentation, izixhobo zasekhaya, umbane wemoto (ukukhanya kokukhanya kunye nokuqala ukutshintshwa komthwalo wemoto), ukutshintshwa kokukhusela ukuvuza.Xa kuthelekiswa nesilivere ye-cadmium oxide, i-tin oxide yesilivere ayinayo i-cadmium yensimbi enetyhefu, apho i-oxide yesinyithi enozinzo oluphezulu lwe-thermal, enombane kunye ne-thermal conductivity, kwinkqubo yokucima inokumelana nobushushu obuphezulu, ukuxhathisa ukhukuliseko lwe-arc kunye i-anti welding, ukwenzela ukuba kuqinisekiswe ukuthembeka kokusebenza kwezixhobo zombane, ukwandisa ubomi benkonzo.Kwaye uphuhliso olukhawulezayo lwe-tin oxide yesilivere, nakweminye i-switch yombane ngaphandle kokwenza utshintsho olukhulu lunokusetyenziswa ngokuthe ngqo kwi-tin oxide yesilivere endaweni ye-AgCdO.Usetyenziso luqala kwi-10A ukuya kwi-100A, kwimisebenzi emininzi ekufutshane nokuba ngcono kunesilivere ye-cadmium oxide.

Iqulathe isixa sesilivere ukwenzela ukuba uthintele izizathu zoqhagamshelwano ezivuthayo, i-terminal yoqhagamshelwano olusisigxina ibe yimo egobileyo, uqhagamshelwano oluguqukayo phakathi kwenkqubo.Ngoko i-arc ayiyi kumphezulu woqhagamshelwano wokutsha.Luhlobo lwefomu yoqhagamshelwano olungcono, kwaye ukusetyenziswa kwayo kuyanda.Inkqubo yokusebenza yoqhagamshelwano lomnxibelelwano ibeka phambili inani leemfuno zezinto.Ngenxa yokuba ubhedu lune-conductivity elungileyo yombane kunye ne-thermal conductivity.Ukuqina okwaneleyo.Iqondo eliphezulu lokunyibilika, ukusetyenzwa lula.Ke isetyenziswa ngokubanzi njengenxalenye yonxibelelwano yoqhagamshelwano lwe-high-voltage breaker circuit.Kodwa ngesandla sobhedu i-oxidized ngokulula, i-oxidation yokumelana noqhagamshelwano.Ke kwezinye izaphuli zesekethe, ubhedu lugqume umaleko wesilivere ngaphandle konxibelelwano oluphambili.

Isilivere ine-conductivity enhle, ifilimu ye-oxide iyaqhuba, inokuphucula ukusebenza koqhagamshelwano lobhedu lwesilivere.Ngokusetyenziswa rhoqo kwe-circuit breaker, uqhagamshelwano lwe-arc thermal effect luyanda kakhulu, umphezulu woqhagamshelwano unokuba yilahleko enkulu, ngoko ke ukuchasana nobushushu besilivere, ukumelana nokumelana ne-arc, ukuxhathisa kwe-abrasion kunye nokubeka phambili iimfuno eziphezulu.Indlela ye-powder metallurgy ivule indlela entsha yokuphuhliswa kwezinto zoqhagamshelwano.
