Kev ua haujlwm ntawm pawg them nyiaj zoo ib yam li cov roj dispenser hauv qhov chaw nres tsheb roj. Nws tuaj yeem kho tau rau hauv av lossis phab ntsa, ntsia rau hauv cov vaj tsev pej xeem (cov tsev pej xeem, cov khw muag khoom, cov chaw nres tsheb pej xeem, thiab lwm yam) thiab cov chaw nres tsheb hauv tsev lossis chaw them nqi, thiab them ntau hom tsheb hluav taws xob raws li qib sib txawv. Cov tswv yim kawg ntawm pawg them nyiaj ncaj qha txuas nrog AC daim phiaj hluav taws xob. Cov zis terminals tau muab faib ua AC thiab DC, thiab tau nruab nrog cov ntsaws ntsaws kom them hluav taws xob tsheb.
Kev nyab xeeb thiab kev ntseeg siab yuav tsum tau txiav txim siab hauv kev tsim cov khoom siv hluav taws xob. Yog li ntawd, cov cuab yeej tiv thaiv kev nyab xeeb thiab txhim khu kev qha yuav tsum tau siv rau kev tiv thaiv overcurrent thiab overvoltage ntawm cov tswv yim kawg, cov zis kawg thiab kev sib txuas lus. Ntawm no peb pom zoo kom muaj hluav taws xob siab thiab siab tam sim no fuse spfj160 los ntawm Littelfuse, tus thawj coj hauv kev lag luam fuse. Cov qauv no yog qhov zoo tshaj plaws tiv thaiv hluav taws xob tiv thaiv kev daws teeb meem rau DC tso zis ntawm pawg them nyiaj thiab tau siv dav hauv thaj chaw them nyiaj.
Spfj series yog thawj fuse muaj npe nyob rau hauv ul2579 daim ntawv pov thawj catalog hauv kev lag luam hluav taws xob, uas yog siv los tiv thaiv 1000VDC, 70-450a high voltage thiab cov khoom siv tam sim no. Nws tsim thiab tsim ua tau raws li qhov yuav tsum tau ua ntawm IEC tus qauv 60269-6, thiab tau dhau VDE 125-450a daim ntawv thov daim ntawv pov thawj. Cov qauv nruj no tuaj yeem ua kom muaj kev nyab xeeb ntawm cov khoom siv thiab cov neeg ua haujlwm, ua spfj series tiag tiag cov khoom lag luam thoob ntiaj teb. 125-450a cov khoom muab J-Class vaj tse loj, uas tuaj yeem txuag tau ntau qhov chaw rau cov khoom lag luam thiab txo cov nqi zoo heev. Nyob rau tib lub sijhawm, Littelfuse ntawm Shiqiang tus neeg sawv cev tuaj yeem muab 1000VDC fuse tuav rau cov koob no kom tau raws li cov kev xav tau tshwj xeeb ntawm qee cov neeg siv khoom.
Qhov ntsuas hluav taws xob ntawm spfj160 yog 1000VDC / 600vac thiab qhov ntsuas tam sim no yog 160A, uas tuaj yeem ua tau raws li qhov xav tau ntawm DC them pawg ntawm ntau qib. Rated tawg tam sim no mus txog 200KA @ 600VAC kab tias 20KA @ 1000VDC, siab dua qhov kev tawg tam sim no txhais tau hais tias lub fuse tsis tshua muaj kev tawg raws li kev txwv, yog li nws muaj kev nyab xeeb dua thiab txhim khu kev qha.
