Tsis muaj teeb meem dab tsi ntawm qhov siab -voltage tam sim no- txwv fuse yog tiv thaiv los ntawm, nws ua haujlwm zoo ib yam: nws tsim cov khoom cua sov uas tsis muaj zog tshaj plaws hauv Circuit Court, hu ua yaj lossis fuse.
Feem ntau hais lus, high voltage tam sim no limiting fuses feem ntau xaiv nyiaj li yaj, nyiaj melting point thiab thermal conductivity yog zoo dua, thiab tsis yooj yim rau oxidize. Thaum luv luv - tam sim no los yog overload tam sim no dhau los ntawm cov yaj, cov nyiaj melts sov thiab melts, thiab ces vaporizes.
Raws li cov hluav taws xob conductivity ntawm hlau vapor yog qis dua li cov khoom thiab cov kua hlau, qhov kev tiv thaiv ntawm cov yaj dheev nce thiab tam sim no hauv Circuit Court dheev txo qis, uas yuav ua rau muaj hluav taws xob siab ntawm ob qho kawg ntawm cov yaj, ua rau qhov sib txawv thiab arc. Nyob rau hauv qhov kev txiav txim ntawm arc, ib tug loj tus naj npawb ntawm gases generated, tsim ib tug muaj zog dissociation nyhuv. Lub arc yog extinguished los yog lub arc raug yuam kom txias nyob rau hauv kev sib cuag nrog ib puag ncig khoom nruab nrab kom tua lub arc.
Feem ntau, arc extinguishing khoom ntawm high voltage tam sim no limiting fuse yog quartz xuab zeb. Qhov no yog vim quartz xuab zeb muaj thermal conductivity thiab rwb thaiv tsev kev ua tau zoo, thiab muaj ib tug loj kev sib cuag cheeb tsam nrog lub arc, uas yog yooj yim mus nqus lub zog arc.
Cov xuab zeb quartz tau ntim rau hauv cov raj yaj ua rau ntau qhov zoo ntawm cov khoom nruab nrab slit zawj, lub arc muaj kev faib, cua txias thiab nto adsorption (them cov khoom), thaum qhov sib txawv ntawm cov roj siab kuj muaj qhov cuam tshuam zoo ntawm lub arc, yog li lub arc yog sai sai tua.
Nyob rau hauv ib txwm ua hauj lwm theem, tam sim no los ntawm cov yaj yog tsawg tshaj li nws rated tam sim no, thiab lub fuse muaj peev xwm khiav lag luam ntseeg tau ntev ntev yam tsis muaj misoperation.
High voltage tam sim no limiting fuses tiv thaiv ntau yam khoom, xws li transformers, motors, voltage transformers, capacitors los yog tis kab.
