Vacuum interrupter ye low voltage circuit breaker
Tsanangudzo pfupi yechigadzirwa:
Vacuum interrupter, inozivikanwawo sekuti vacuum switch chubhu, ndiyo yakakosha chikamu chepakati-yakakwirira voltage simba switch.Basa guru revacuum interrupter nderekuita kuti yepakati uye yakakwira voltage yedunhu ibvise magetsi evhacuum arc yekudzimisa kamuri yeceramic shell kuburikidza nekunakisisa kwekuvharira kwevacuum mukati mechubhu, iyo inogona kukurumidza kudzima arc uye kudzvinyirira ikozvino. , kuitira kudzivirira tsaona netsaona.
A vacuum interrupter anoshandisa vacuum yakakwirira kudzima arc pakati pemabatirwo maviri.Sezvo macontacts anofamba akaparadzana, ikozvino inoyerera kuburikidza nenzvimbo diki.Pane kuwedzera kwakanyanya kwekupikisa pakati pevanosangana, uye kutonhora panzvimbo yekubatana kunowedzera nokukurumidza kusvikira kuitika kwe electrode-metal evaporation.Panguva imwecheteyo, munda wemagetsi wakanyanya kukwirira padiki rekubatana gap.Kuparara kwegomba kunoburitsa vacuum arc.Sezvo iyo inotsinhanisa ikozvino inomanikidzwa kupfuura ne zero yekutenda kune arc kuramba, uye mukaha pakati peakamisikidzwa uye anofamba anobatika anowedzera, conductive plasma inogadzirwa nearc inosimuka kubva pagomba uye inova isiri-conductive.Ikozvino inovhiringwa.
AMF neRMF vanobatika vane spiral (kana radial) slots yakachekwa muzviso zvavo.Chimiro chemacontacts chinoburitsa magineti masimba ayo anofambisa arc nzvimbo pamusoro pepamusoro pemabatirwo, saka iyo arc haigare munzvimbo imwechete kwenguva yakareba.Iyo arc inogovaniswa zvakaenzana pamusoro penzvimbo yekubata kuchengetedza yakaderera arc voltage uye kuderedza kukukurwa kwekubatana.
Mushure mekunge nzvimbo dzapera uye dzakacheneswa ne electroplating uye kuongororwa kwemaziso kwepamusoro-soro yezvikamu zvose zvaitwa, iyo inovhiringidza inounganidzwa.High-vacuum solder inoshandiswa pazvisungo zvezvikamu, zvikamu zvakarongeka, uye zvinokanganisa zvinogadziriswa.Sezvo utsanana panguva yegungano inonyanya kukosha, mabasa ose anoitwa pasi pemamiriro e-air-conditioned clean-room.Nenzira iyi mugadziri anogona kuvimbisa anogara akakwira mhando yevanovhiringidza uye yepamusoro inogoneka ratings kusvika ku100 kA zvinoenderana neIEC/IEEE 62271-37-013.
