Vacuum ama-circuit breakers , noma ama-VCB, angamathuluzi okushintsha ugesi asebenzisa ubuchwepheshe be-vacuum ukuphazamisa amaza kagesi. Banikeza izinzuzo eziningi ngaphezu kwama-circuit breaker, okuhlanganisa izikhathi zokuphendula ezisheshayo, ukunakekelwa okuphansi, nokuphila isikhathi eside. Kulesi sihloko, sizohlinzeka ngencazelo yomkhiqizo enemininingwane, sichaze ukuthi isetshenziswa kanjani, futhi sixoxe ngendawo osebenza kuyo kakhulu.
Incazelo Yomkhiqizo
Ai-vacuum circuit breaker iqukethe ibhodlela levacuum eliqukethe isakhiwo sokuxhumana. Lapho isifunda sivaliwe, isakhiwo sokuxhumana sibanjwe endaweni yesiphethu. Lapho isifunda sivulwa, isakhiwo sokuxhumana sikhishwa kude noxhumana nabo, sakha i-arc. Ibhodlela le-vacuum lenzelwe ukucisha i-arc ku-vacuum, ukuvimbela ukulimala ezingxenyeni zikagesi. Ama-VCB atholakala ngebanga losayizi, amazinga kagesi, namandla okuphazamisa, okuwenza afanelekele izindawo ezahlukahlukene.
Ukusetshenziswa
Ukusebenzisa ai-vacuum circuit breaker kuyinqubo eqondile. Uma kwenzeka iphutha kusekethe, i-VCB kufanele ivulwe. Lokhu kungenzeka mathupha noma ngokuzenzakalelayo, kuye ngohlelo lokusebenza. Kuzinhlelo zokusebenza ezenziwa ngesandla, i-VCB ingavulwa ngesibambo noma ngokushintsha. Ezinhlelweni ezizenzakalelayo, izinzwa zithola iphutha, bese i-VCB ivuleka ngokuzenzakalelayo.
Imvelo
Ama-circuit breaker afanele indawo ehlukahlukene, kufaka phakathi izizinda zezimboni nezitshalo zikagesi. Ngokuvamile zisetshenziselwa ukuvikela amajeneretha, ama-transformer, nezinye izinto zikagesi. Ama-VCB akhethwa ngaphezu kwama-circuit breaker ezindaweni lapho izikhathi zokuphendula ngokushesha zibalulekile. Zifanele futhi izicelo ze-high-voltage lapho izinga eliphezulu lokuthembeka liyadingeka. Ama-VCB awanakekelo eliphansi, okuwenza alungele izindawo lapho ukusevisa kungase kube inselele khona, njengezinsimbi zikawoyela zasogwini noma iziza ezikude.
Izinzuzo
Ama-VCB anikeza izinzuzo eziningi ngaphezu kwama-breaker circuit. Okokuqala, banesikhathi sokuphendula esisheshayo, okubenza bafaneleke kakhulu izinhlelo zokusebenza ezinesivinini esikhulu. Okwesibili, azinakekelo eliphansi futhi ziphila isikhathi eside, okuholela ezindlekweni eziphansi ngokuhamba kwesikhathi. Ekugcineni, zisebenza buthule futhi azikhiqizi noma yimaphi amagesi ayingozi, okuzenza zibe inketho evumelana nemvelo.
Ukucatshangelwa
Uma ucubungula i-vacuum circuit breaker, kubalulekile ukukhetha usayizi ofanele, izinga le-voltage, nokuphazamisa umthamo. Ama-VCB abiza kakhulu kunama-circuit breaker, kepha izindleko zilungiswa ngezinzuzo zawo eziningi. Kubalulekile futhi ukuqinisekisa ukuthi i-VCB ifakiwe futhi igcinwa ngendlela efanele ukuze kuqinisekiswe ukuthi isebenza ngempumelelo lapho kudingeka.
Isiphetho
Sengiphetha, ama-circuit breaker anikeza izinzuzo eziningi ngaphezu kwama-breaker circuit, okuhlanganisa izikhathi zokuphendula ngokushesha, ukulungiswa okuphansi, nokuphila isikhathi eside. Zifanele uhla lwezindawo, okuhlanganisa iziza zezimboni nezitshalo zikagesi, futhi zilungele ukusetshenziswa kwezicelo ezinesivinini esikhulu. Uma ucabangela i-VCB, kubalulekile ukukhetha usayizi olungile, izinga le-voltage, nomthamo ophazamisayo. Angase abize kakhulu kunama-circuit breakers, kodwa izinzuzo ziwenza ube utshalomali olufanele. Ngokukhetha i-vacuum circuit breaker, ungathuthukisa ukuphepha nokuthembeka kwezinhlelo zakho zikagesi.
