I-arc chamber yama-low-voltage circuit breaker, okukhethekile kwayo okubandakanya: amapuleti ensimbi amaningi amise okwe-U;indawo ebiyelwe eyenziwe ngezinto ezivikelayo ezimise okwe-parallelelepiped futhi inezindonga ezimbili ezisemaceleni, udonga olungezansi, udonga olungaphezulu nodonga lwangemuva, izindonga ezisemaceleni ezinezikhala, ngaphakathi, eziningi eziphambene ukuze kufakwe insimbi. amapuleti, izindonga ezingezansi nezingaphezulu ngayinye inesikhala esisodwa futhi indawo ebiyelwe ivuliwe ngaphambili.
Kuyaziwa ukuthi izigebengu zesekhethi zamandla abunjiwe zivame ukusetshenziswa ezinhlelweni zikagesi ezine-voltage ephansi yezimboni, okungukuthi, amasistimu asebenza afika cishe ku-1000 Volt.Ama-circuit breaker ngokuvamile ahlinzekwa ngohlelo oluqinisekisa ukuthi amandla amanje adingekayo kubasebenzisi abahlukahlukene, ukuxhuma nokunqanyulwa komthwalo, ukuvikela kunoma yiziphi izimo ezingavamile, njengokulayishwa ngokweqile kanye ne-short-circuit, ngokuvula isekethe ngokuzenzakalelayo, kanye ukunqanyulwa kwesifunda esivikelwe ngokuvula othintana nabo abahambayo ngokuphathelene nokuxhumana okuhleliwe (ukuhlukaniswa kwe-galvanic) ukuze kuzuzwe ukuhlukaniswa okugcwele komthwalo ngokuphathelene nomthombo wamandla kagesi.
Umsebenzi obalulekile wokuphazamisa i-current (kungakhathaliseki ukuthi igama, ukulayisha ngokweqile noma i-short-circuit current) uhlinzekwa yi-breaker circuit engxenyeni ethile ye-circuit breaker eshiwo eyakhiwe yilokho okubizwa ngokuthi i-deionizing arc chamber.Njengomphumela wokunyakaza kokuvula, i-voltage phakathi koxhumana nabo ibangela ukukhishwa kwe-dielectric emoyeni, okuholela ekwakhekeni kwe-arc kagesi ekamelweni.I-arc iqhutshwa yimiphumela ye-electromagnetic kanye ne-fluid-dynamics ngaphakathi kochungechunge lwamapuleti ensimbi ahlelwe ekamelweni, okuhloswe ngalo ukucisha i-arc eshiwo ngokupholisa.Ngesikhathi sokwakhiwa kwe-arc, amandla akhishwe umphumela we-Joule aphezulu kakhulu futhi abangela izingcindezi ezishisayo nezomshini ngaphakathi kwendawo yokuqukatha amapuleti.
