Txheej txheem cej luam
High voltage fuse yog qhov tsis muaj zog tshaj plaws uas tau teeb tsa hauv daim phiaj hluav taws xob.Thaum cov dej ntws dhau los, lub ntsiab lus nws tus kheej yuav sov thiab fuse, thiab lub voj voog yuav tawg los ntawm lub luag haujlwm ntawm arc extinguishing nruab nrab los tiv thaiv cov kab hluav taws xob thiab cov khoom siv hluav taws xob.Fuses yog dav siv nyob rau hauv me me fais fab daim phiaj nrog voltage qis dua 35 kV.
Lub fuse muaj xws li fuse tube, hu rau conductive system, post insulator thiab base phaj (los yog mounting phaj).Nws tuaj yeem muab faib ua tam sim no txwv fuse thiab poob fuse.
Qauv
Lub fuse ntawm no series muaj ob tug ncej insulators, hu rau puag, fuse raj thiab puag phaj.Cov ncej insulator yog ntsia rau ntawm lub hauv paus phaj, lub rooj sib txuas yog tsau rau ntawm cov ncej insulator, thiab lub fuse tube muab tso rau hauv lub rooj sib tham thiab tsau, tab sis lub kaus mom tooj liab ntawm ob qho kawg yog qhov txhab ntawm lub plooj (porcelain raj), thiab lub fuse. nyob rau hauv lub fuse chim yog ntsuas raws li tam sim no loj.Ib los yog ntau tshaj fuses raug mob ntawm lub ribbed core (rated tam sim no tsawg dua 7.5A) los yog ncaj qha ntsia hauv lub raj ( ntsuas tam sim no ntau dua 7.5A), thiab tom qab ntawd ntim nrog quartz xuab zeb.Copper npog yog siv rau ntawm ob qho kawg.Thaum lub overload tam sim no los yog luv Circuit Court tam sim no dhau, lub fuse yuav tshuab tam sim ntawd, thiab lub arc yuav raug generated nyob rau tib lub sij hawm, thiab quartz xuab zeb yuav tua lub arc tam sim ntawd.Thaum lub fuse tshuab, lub cable ntawm lub caij nplooj ntoos hlav kuj tshuab thiab tawm ntawm lub caij nplooj ntoos hlav, qhia tias lub fuse yog cua tshuab.Ua kom tiav txoj haujlwm.
Cov lus qhia rau kev siv
RN1 hom sab hauv tsev puv quartz xuab zeb fuse, haum rau:
(1) Qhov siab tsis siab tshaj 1000 meters.
(2) Qhov kub ntawm ib puag ncig nruab nrab tsis siab tshaj +40 ℃, tsis qis dua -40 ℃.
Hom RN1 fuses tsis tuaj yeem ua haujlwm hauv ib puag ncig hauv qab no:
(1) Cov chaw sab hauv tsev nrog cov av noo ntau dua 95%.
(2) Muaj qhov chaw muaj kev phom sij ntawm cov khoom siv hluav taws kub thiab tawg.
(3) Qhov chaw muaj kev vibration hnyav, viav vias lossis cuam tshuam.
(4) Cov cheeb tsam nrog qhov siab tshaj 2,000 meters.
(5) Cov huab cua muaj kuab paug thiab qhov chaw tshwj xeeb humid.
(6) Cov chaw tshwj xeeb (xws li siv hauv cov khoom siv xoo hluav taws xob).
