HRW / HRXWO 10-35KV 10A Sab nraum zoov cov pa phem resistant hom silicon roj hmab siab voltage tam sim no limiting fuse

High voltage tam sim no limiting fuse muaj feem xyuam rau sab hauv tsev AC 50Hz, rated voltages ntawm 3.6KV, 7.2KV, 12KV, 24KV, 40.5KV, ntsuas tam sim no ntawm 0.5 thiab 2, 3, 5, 7.5, 10A systems, thiab muaj feem xyuam rau kev tiv thaiv. overload thiab luv Circuit Court txhaum ntawm sab nraum 35KV voltage transformers thiab fais fab kab.Nws tuaj yeem siv ua ke nrog lwm cov khoom siv hloov pauv, xws li cov khoom hloov pauv thiab cov contactors tiag tiag, ua cov khoom tiv thaiv luv luv thiab dhau ntawm lub zog hloov hluav taws xob thiab lwm yam khoom siv thaub qab, thiab tseem yog ib qho tsim nyog txhawb cov khoom siv rau high-voltage hloov thav duab, nplhaib. network thav duab, thiab high / low-voltage prefabricated substations.
High voltage tam sim no limiting fuse muaj tsawg tam sim no thiab ceev ceev.Tus nqi siab tshaj ntawm qhov txhaum tam sim no feem ntau tshwm ib nrab nthwv dej.Thaum tus choj lub cev raug txiav, tag nrho cov luv luv tam sim no yuav raug xa mus rau lub high-voltage tam sim no limiting fuse.Nyob rau hauv luv luv Circuit Court tam sim no ntawm lub fuse yuav vaporize, tawg, tsim arc nruab nrab ntawm qhov khoob thiab tua lub arc yav tom ntej thiab thaum nws sawv, txwv thiab yuam txiav tawm luv luv Circuit Court tam sim no (t ＜ 2ms), kom qhov tam sim no tsis tuaj yeem. ncav cuag tus nqi siab tshaj ntawm qhov luv luv tam sim no.Thaum qhov luv luv tam sim no nce mus rau Ip, lub fuse yuav fuse thiab txiav tawm tam sim no.Qhov kev txiav tawm tam sim no Ip tsuas yog kwv yees li 15% ntawm tus nqi siab tshaj ntawm qhov xav tau tam sim no, zoo heev txo qhov cuam tshuam ntawm qhov txhaum tam sim no ntawm lub zog hluav taws xob thiab thermal nyhuv ntawm lub zog tsim thiab cov cuab yeej hloov pauv.Lub arc voltage generated los ntawm high-voltage tam sim no limiting fuse yuav raug txwv los ntawm nonlinear tsis kam, uas tuaj yeem koom tes nrog tus choj tiv thaiv los daws qhov teeb meem ntawm lub peev xwm tsis txaus ntawm high-voltage tam sim no limiting fuse thiab txhim kho daim ntawv thov ntau yam ntawm tag nrho. ntaus ntawv.
Lub fuse yog tsim los ntawm cov raj yaj, cov plooj (porcelain bushing) (silicone rubber insulation sheath), fastening flange, transverse post insulator and a terminal.Txhim kho lub kaus mom lub davhlau ya nyob twg thiab cov kav dej yaj ntawm ob qho kawg hauv cov plooj (porcelain bushing) los ntawm nias, thiab tom qab ntawd kho cov plooj (porcelain bushing) ntawm tus pas nrig ncej insulator nrog cov khoom flange.
Cov yeeb nkab yaj tau txais kev saib xyuas nrog siab silicon oxide raws li qhov nruab nrab ntawm kev tua hluav taws, thiab cov hlau hlau uas muaj txoj kab me me yog siv los ua lub fuse.Thaum lub overload tam sim no los yog luv luv tam sim no dhau los ntawm lub raj yaj, lub fuse yuav yaj tam sim ntawd.Lub arc tshwm sim nyob rau hauv ob peb parallel nqaim slits.Cov hlau vapor nyob rau hauv arc nkag mus rau hauv quartz xuab zeb, muaj zog dissociated, thiab sai extinguishes lub arc.Yog li ntawd, lub fuse muaj kev ua tau zoo thiab muaj peev xwm tawg loj.
