Vacuum interrupter yekutengesa kunze TD-17.5/630-21 (188)
Tsanangudzo pfupi yechigadzirwa:
Subassemblies yevacuum interrupters yakatanga kuunganidzwa uye yakasimbiswa pamwechete muchoto chehydrogen-atmosphere.Chubhu yakabatana nemukati memuvharidzi yakashandiswa kuburitsa chinovhiringidza nepombi yekuvharisa yekunze uku chinovhiringidza chaichengetwa chiri pa400 °C (752 °F).Kubva kuma1970s, zvinokanganisa zvikamu zvakaunganidzwa muchoto chepamusoro-vacuum brazing neyakasanganiswa brazing-uye-evacuation process.Makumi (kana mazana) emabhodhoro anogadziriswa mubatch rimwe chete, achishandisa muto wepamusoro-vacuum unopisa patembiricha kusvika ku900 ° C uye kumanikidzwa kwe10-6 mbar.Saka, vanovhiringidza vanozadzisa zvinodiwa zvemhando "yakasimbiswa kwehupenyu hwese".Nekuda kweiyo otomatiki yekugadzira maitiro, iyo yemhando yepamusoro inogona kugara ichigadzirwa chero nguva.
Zvadaro, kuongororwa kwevanovhiringidza nenzira ye-X-ray nzira inoshandiswa kuongorora zvigaro pamwe nekukwana kwezvikamu zvemukati, uye kunaka kwezvibodzwa zvebrazing.Inochengetedza mhando yepamusoro yevacuum interrupters.
Panguva yekugadzira, iyo chaiyo yemukati dielectric simba yevacuum interrupter inomiswa nekuwedzera zvishoma nezvishoma voltage, uye izvi zvinosimbiswa neinozotevera mheni impulse voltage test.Mashandiro ese ari maviri anoitwa nehunhu hwepamusoro pane hwakatsanangurwa mumiyero, sehumbowo hwemhando yevacuum interrupters.Ichi ndicho chinodiwa chekutsungirira kwenguva refu uye kuwanikwa kwepamusoro.
Mune mamwe mamiriro ezvinhu, vacuum circuit breaker inogona kumanikidza yazvino mudunhu kusvika zero pamberi pezvakasikwa zero (uye kudzoreredzwa kwezvino) munharaunda inochinja-chinja.Kana interrupter oparesheni nguva isingafadzi maererano neAC-voltage waveform (kana arc yadzimwa asi macontacts achiri kufamba uye ionization haisati yaparara mune inovhiringidza), voltage inogona kudarika gap's stand voltage.
Mazuva ano, nekudzikira kwazvino kutema, vacuum circuit breakers haizokonzeresa kuwandisa kunogona kuderedza insulation kubva kumidziyo yakatenderedza.
