Kuitwa kwevacuum arc yekudzima kamuri inogadzirisa mashandiro eiyo contactor, uye ma mechanical maitiro e contactor pachawo anoonawo kushanda kwevacuum arc yekudzima kamuri.Kuti kushanda kwevacuum contactor kunosangana nezvinodiwa zvinonyanya kuenderana nekuti maitiro ayo emagetsi anozadzisa zvinodiwa. yekufananidza vacuum arc yekudzima kamuri.
Kutanga, kutarisa kwekutanga kumanikidziro ekubatana.Apo iyo vacuum arc yekudzima kamuri inobata pasina simba rekunze, maitiro ane simba anovhara ne static contacts pasi pechiito chemhepo yemhepo, iyo inonzi autistic force.Kukura kwesimba kunoenderana. pachiteshi chengarava chinoyambuka-chikamu nharaunda yemavhuvhu.Kazhinji, simba rekuvhara harigoni kuvimbisa kubatwa kwemagetsi kwakakodzera pakati pemagetsi uye static contacts yevacuum arc yekudzima kamuri, uye kunze kwekunze kunowedzera.Iyo yakayerwa ikozvino yekamuri yearc;b.Iyo arc chamber yekubatanidza zvinhu;c.Kudzora kwemagetsi pakati pesimba uye static contacts kana kamuri yearc yakavharwa. Maererano nezvinhu izvi kusarudza zvakakodzera kushandiswa kushandiswa, simba rekuvhara uye kudzvinyirira kwekunze kwepamusoro kunonzi kukanganiswa kwekubatana kwemusoro wekubatana, kunonziwo kudzvinyirira kwekupedzisira.
2. Basa rekupedzisira kumanikidziro pane contactor.Reasonable terminal pressure, Iva nechokwadi chekugadzirisa kupikisa kwehutano pakati pemagetsi uye static contacts yekamuri yekudzima arc, Kubata kupikisa kunogona kuyerwa nekugadzirisa dunhu;Inonzwisisika terminal yekumanikidza, Inogona kusangana nezvinodiwa zvesimba rinopisa kugadzikana kwevacuum arc yekudzima kamuri, Inogona kukunda kudzoreredza pakati pevanobatika munzvimbo yakakwira yazvino, Kuona kuvharwa kwakazara pasina kukuvara, ndiko kuti, vanobatika havazonamatira rufu;Inonzwisisika terminal pressure, Inogona kuderedza kudzikiswa, Simba rekuita rinokonzeresa kubata kana rakavharwa, Kunyudzwa neiyo elastic inogona simba;Inonzwisisika terminal pressure, Mukuita kushandura hunhu, Kana iyo terminal pressure ikasangana nezvinodiwa, Iyo yekusangana chitubu compression yakakurawo, Iyo elastic inogoneka simba ihombe, Kuwedzera kumhanya kwekutanga kwegedhi rekuchinja, Kuderedza kupisa kwearc nguva uye kuvandudza simba rekuchinja.
Tatu, tsanangudzo uye basa re overtravel.Any vacuum switch yakavharwa mu overstroke mode, kana yakavharwa, masangano ane simba haakwanisi kuenderera mberi mushure mekubata ma static contacts, asi kudzvinyirira pakati pevanoshamwaridzana vane simba vanoda.Iyi dzvinyiriro inowanikwa nekubatana. chitubu.Kana kufamba uye kufamba kunodhumhana, simba riri pachitubu chekusangana rinoramba richifamba.Iyo kureba kwekufamba panguva yekufamba ndeyekumanikidza sitiroko yekusangana kwechitubu, inova iyo overstroke.Kuwedzera pakuwedzera kukurumidza kwekutanga kwekuchinja, overstroke ine mabasa maviri akakosha: a.Simba rekusangana kwechitubu rinopfuudzwa kune kudzvanywa kwekubatana pakati pevanobatika kuti vasangane nezvinodiwa zvekushanda;b.Mushure mekushanda kwenguva refu kweiyo contactor, vanobatika vanopisa uye kuderedza huwandu hwese hwevanobatika.Kana overstroke inonzwisisika ichivimbiswa, imwe terminal pressure inogona kuita kuti vacuum contacts dzishande zvakajairwa.Ichokwadi, iyo yekubata yekumanikidza chitubu yakapa kudzvanywa kweiyo contactor switch state, iri kuvhara nguva yekusangana, kusvika kune prepressure kukosha kudzikisa. iyo yekuvhara bounce, kana iyo overstroke movement inopera, iyo terminal pressure inosanganawo nezvinodiwa zvekugadzira.
