Ring Main Unit thiab Nws Daim Ntawv Thov
Nrog rau txoj kev loj hlob sai ntawm Tuam Tshoj txoj kev lag luam kev lag luam, cov tsev siab siab tau teeb tsa hauv ntau lub nroog. Thaum txoj haujlwm ntawm lub nroog tau dhau los ua ntau dua thiab zoo meej thiab nyuaj, qhov kev thov rau kev ntseeg siab ntawm cov khoom siv hluav taws xob kuj siab dua, thiab ntau tus neeg siv yuav tsum tau siv ob lossis ntau lub zog. Nyob rau hauv cov nroog ntug dej hiav txwv tsim, piv txwv li, qhov ntom ntawm cov tsev niaj hnub hauv nroog tau nce, nrog rau qhov nyuaj ntawm txoj kab kev tsim kho, thiab daim phiaj hluav taws xob kuj tau ua nyuaj dua, thiab ib zaug muaj kev txhaum hauv Circuit Court, nws nyuaj rau txheeb xyuas thiab kho nws hauv lub sijhawm luv luv. Nyob rau hauv cov xwm txheej no, qhov kev tsis sib haum xeeb ntawm cov tsoos hluav taws xob faib hluav taws xob thiab cov kev xav tau ntawm cov hluav taws xob ntau zuj zus tau tsim, thiab kev txhim kho ntawm cov khoom siv hluav taws xob ib txwm siv los ua qhov tsis muaj tseeb. Lub hav zoov ntawm lub nplhaib tseem ceeb muab qhov kev daws teeb meem zoo tshaj plaws rau qhov kev tsis sib haum xeeb no.
Lub nplhaib tseem ceeb yog ib pawg ntawm cov khoom sib kis thiab cov khoom xa tawm tau nruab rau hauv cov hlau lossis cov khoom tsis yog xim hlau los yog ua rau hauv lub caij nyoog hom nplhaib network fais fab mov chav tsev ntawm cov khoom siv hluav taws xob, qhov tseem ceeb ntawm cov khoom siv thauj khoom hloov thiab fuse, nrog qhov zoo ntawm cov qauv yooj yim, ntim me me, tus nqi qis, tuaj yeem txhim kho cov khoom siv hluav taws xob thiab kev ua haujlwm thiab kev nyab xeeb ntawm cov khoom siv hluav taws xob. Nws yog dav siv nyob rau hauv cov chaw faib khoom thiab lub thawv-hom substations nyob rau hauv cov chaw thauj khoom ntawm cov neeg nyob hauv nroog, cov tsev siab, cov tsev loj, cov chaw tsim khoom thiab cov lag luam. Tam sim no, feem ntau siv lub nplhaib tseem ceeb hauv Suav teb feem ntau yog kev sib txuas ntawm kev hloov pauv thiab cov khoom siv fuse, cua insulated load hloov cov txee, ua raws li lub tshuab nqus tsev hloov khoom. Yav dhau los, kev hloov pauv hauv tsev muaj kev sib cuag tsis zoo, peb theem tsis tau synchronized rau kev ua haujlwm tawg, kev ua txhaum lub peev xwm ua me me, kev ua haujlwm tsis yooj yim, lub neej luv luv no tsis zoo, kev teeb tsa hauv Circuit Court breaker txee raug txwv, thiab lub nplhaib tseem ceeb tau hloov pauv cov khoom siv hluav taws xob nrog cov khoom siv hluav taws xob nkaus xwb.
Nyob rau hauv lub load hloov thiab fuse ua ke lub nplhaib lub ntsiab chav tsev, lub fuse yog ib tug tam sim no-txheej fuse uas muaj peev xwm tiv taus siab tawg tam sim no, thiab lub arc tshwm sim los ntawm melting ntawm lub fuse nyob rau hauv lub qhib txheej txheem yog cuam tshuam los ntawm quartz xuab zeb mus ua txhaum lub Circuit Court, thaum lub fuse firing pin pib lub caij nplooj ntoos hlav cia impactor ntawm lub load hloov mus synchronize lub peb ncej kev sib cuag, tag nrho lub sij hawm ntawm lub load hloov. inverse lub sij hawm txwv. Tsis pub dhau 10ms, lub faulty fais fab mov raug txiav tawm sai sai, thiab nws tsis yooj yim los tshwm sim qhov tshwm sim ntawm qhov ploj lawm theem fais fab mov. Vim lub sij hawm luv luv, qhov hloov pauv tam sim no (lub fuse ntawm lub fuse melts kom lub caij nplooj ntoos hlav cia impactor yuav yog qhov txhaum tam sim no los ntawm txoj kab thaum lub sij hawm tag nrho cov txheej txheem ntawm lub load hloov tawg) yog ntau me dua lub ncov txhaum tam sim no, zoo tiv thaiv nws cov kab thiab khoom siv. Yog li ntawd, lub load hloov thiab fuse lub nplhaib tseem ceeb tiv thaiv chav tsev muaj kev nyab xeeb thiab txhim khu kev qha, thiab cov kab tsim tsis xav tau kev ntsuas luv luv tam sim no, tab sis kuj txuag tus nqi ntawm cov kab. Cov qauv ntawm Ring lub ntsiab chav tsev yog compact, thiab nws cov cua kub dissipation kev ua tau zoo dua li lub laub-hom txee. Nws cov ncej loj me me, lub sijhawm no nws tuaj yeem ntsia tau rau ntawm phab ntsa lossis deb ntawm phab ntsa. Nws cov hneev taw me me kuj tseem txuag cov nqi tsim kho pej xeem.
