Kuti udzivise nekuda kwesirivheri yekubatira kupisa, static yekubata terminal kuita yakakomberedzwa chimiro, yepakati yekubatana inobuda chikamu.Saka iyo arc haingaite pane yekubata kumeso kwekupisa.Iri imhando yefomu yekubata iri nani, uye kushandiswa kwayo kuri kuwedzera kuwanda.Nzira yekushanda yekubatana kwekubatana inoiswa mberi nhamba yezvinodiwa zvezvinhu.Nokuti mhangura ine yakanaka magetsi conductivity uye thermal conductivity.Zvakakwana kuoma.Nzvimbo yepamusoro yekunyungudika, nyore kugadzirisa.Saka inoshandiswa zvakanyanya seyekusangana conductive chikamu chepamusoro voltage wedunhu breaker.Asi neruoko rwemhangura iri nyore oxidation, iyo oxidation yekusangana kwekupokana.Saka mune mamwe mabreaker breaker, mhangura yakavhara sirivheri layer kunze kwekusangana kukuru.

Sirivha ine yakanaka conductivity, iyo oxide firimu iri conductive, inogona kuvandudza mashandiro esirivha akaputirwa mhangura yekubatana.Nekugara uchishandiswa kwedunhu breaker, sirivheri yekubata arc thermal mhedzisiro yakawedzera zvakanyanya, iyo yekubata kumeso inogona kunge iri kurasikirwa kwakanyanya, saka sirivheri yekubata kupisa kwekudzivirira, kuramba kune arc kuramba, abrasion kuramba uye kuisa mberi kwepamusoro zvinodiwa.Powder metallurgy nzira yakavhura nzira nyowani yekuvandudzwa kwezvinhu zvekusangana.

Powder metallurgy pachinzvimbo chekushandisa yakajairwa metallurgical method, asi iwo maviri marudzi esimbi poda yakasanganiswa pamwe chete mu mold pressing forming.Mune gasi rekudzivirira (hydrogen) mukuita sintering.Rudzi urwu rwegoridhe chaizvoizvo musanganiswa weTaiwan.Nokuti maitiro acho akafanana neceramic chigadzirwa, inonziwo mold alloy.High voltage circuit breaker inoshandiswa zvakanyanya nemhangura tungsten, sirivheri nickel, sirivheri, graphite seyakabatana kuramba kune arc kana mhete arc kuramba.Inoshandiswa mune relays, macontactor, mhepo inochinja, muganhu wekuyerera switch, mota inodzivirira, micro switch, chiridzwa, midziyo yemumba, mota yemagetsi (light switch uye kutanga mota inotakura switch), leakage protection switch.Kana ichienzaniswa nesirivheri cadmium oxide, sirivheri tin oxide haina chepfu simbi cadmium, umo iyo simbi oxide ine yakanyanya kugadzikana yekupisa, ine yakanaka magetsi uye yekupisa conductivity, mu-off process ine yakanyanya kupisa kupisa, arc erosion resistance uye. anti welding, kuitira kuti uve nechokwadi chekuvimbika kwekushanda kwemidziyo yemagetsi, kuwedzera hupenyu hwebasa.Uye kukurumidza kukura kwesirivheri tin oxide, kunyangwe mune imwe yemagetsi switch pasina kuita shanduko huru inogona kushandiswa zvakananga sirivheri tin oxide kutsiva AgCdO.Mashandisirwo anotangira pa10A - 100A, mukuita kwakawanda kuri pedyo nekutonaka kupfuura sirivheri cadmium oxide.

Iine huwandu hwesirivheri kuitira kuti udzivise kusangana nekupisa zvikonzero, static yekubata terminal kuita yakakomberedzwa chimiro, ine simba kubata mukati mechikamu chemaitiro.Saka iyo arc haingaite pane yekubata kumeso kwekupisa.Iri imhando yefomu yekubata iri nani, uye kushandiswa kwayo kuri kuwedzera kuwanda.Nzira yekushanda yekubatana kwekubatana inoiswa mberi nhamba yezvinodiwa zvezvinhu.Nokuti mhangura ine yakanaka magetsi conductivity uye thermal conductivity.Zvakakwana kuoma.Nzvimbo yepamusoro yekunyungudika, nyore kugadzirisa.Saka inoshandiswa zvakanyanya seyekusangana conductive chikamu chepamusoro voltage wedunhu breaker.Asi neruoko rwemhangura iri nyore oxidation, iyo oxidation yekusangana kwekupokana.Saka mune mamwe mabreaker breaker, mhangura yakavhara sirivheri layer kunze kwekusangana kukuru.

Sirivha ine yakanaka conductivity, iyo oxide firimu iri conductive, inogona kuvandudza mashandiro esirivha akaputirwa mhangura yekubatana.Nekugara uchishandiswa kwecircuit breaker, kubata arc thermal athari inowedzera zvakanyanya, kubata kumeso kunogona kuve kurasikirwa kwakakomba, saka sirivheri yekubata kupisa kuramba, kuramba arc kuramba, abrasion kuramba uye kuisa mberi kwepamusoro zvinodiwa.Powder metallurgy nzira yakavhura nzira nyowani yekuvandudzwa kwezvinhu zvekusangana.
