Izisombululo zezakhiwo.

Ukunyuka - umngcipheko ongaphantsiI-Surges yingozi ehlala ijongelwa phantsi.Ezi pulses zamandla ombane (transients) ezithatha kuphela isibini sesibini zibangelwa ukubetha kombane ngokuthe ngqo, kufutshane kunye nokude okanye ukutshintshwa kwemisebenzi yombane.Umbane othe ngqo nakufutshane

Ukubetha kombane ngokuthe ngqo okanye kufutshane kukubetha umbane kwisakhiwo, kufutshane naso okanye kwimigca engena kwisakhiwo (umz. inkqubo yonikezelo lwamandla ombane ombane ophantsi, unxibelelwano ngefowuni kunye neengcingo zedatha).Ubukhulu kunye nomxholo wamandla weziphumo zemisinga yempembelelo kunye nombane we-impulse kunye ne-electromagnetic field ehambelana nayo (LEMP) isoyikisa kakhulu inkqubo ukuba ikhuselwe.

Umsinga wombane obangelwa kukubetha kombane ngokuthe ngqo kwisakhiwo ubangela ukunyuka kwamandla eevolthi ezininzi ze-100,000 kuzo zonke izixhobo zomhlaba.Izandi zibangelwa kukuhla kwamandla ombane kwindawo eqhelekileyo ye-earthing impedance kunye nesiphumo sokunyuka okunokwenzeka kwesakhiwo ngokuphathelele kokusingqongileyo.Olu lolona xinzelelo luphezulu kwiinkqubo zombane kwizakhiwo.

Ukongeza kokuhla kwamandla ombane kwindawo yesiqhelo ye-earthing impedance, utyando lwenzeka kufakelo lombane lwesakhiwo nakwiinkqubo eziqhagamshelweyo kunye nezixhobo ngenxa yesiphumo sokungeniswa kombane wombane wombane.Amandla ala maza ombane abangelwayo kunye nemisinga yempembelelo yesiphumo angaphantsi kwaleyo yombane wempembelelo yangoku.

Ukubetha umbane kude

Ukubetha kombane okukude kukubethelwa kombane kude lee kwinto eza kukhuselwa, kuthungelwano lwe-voltage oluphezulu lomgca we-medium-voltage okanye ngokusondeleyo kunye nokukhutshwa kwelifu-to-lifu.

Ukutshintsha imisebenzi

Ukutshintsha imisebenzi yezixhobo zamandla kubangela ukunyuka (SEMP - Ukutshintsha i-Electromagnetic Pulse) malunga ne-volts ye-1,000 kwiinkqubo zombane.Zenzeka, umzekelo, xa imithwalo ye-inductive (umz. i-transformer, i-reactors, ii-motor) icinyiwe, ii-arcs zivutha okanye uhambo lwe-fuses.Ukuba unikezelo lwamandla kunye neengcingo zedatha zifakwe ngokufanayo, iinkqubo ezinovakalelo zingaphazamiseka okanye zitshatyalaliswe.

Ukukhuselwa konikezelo lwamandla kunye neenkqubo zedatha

Ukutshatyalaliswa okutshabalalisayo kwizakhiwo zokuhlala, iiofisi kunye nezakhiwo zolawulo kunye nezityalo zemizi-mveliso kunokwenzeka ukuba zenzeke, umzekelo, inkqubo yokubonelela ngombane, inkqubo yeteknoloji yolwazi kunye nenkqubo yefowuni, iinkqubo zokulawula izibonelelo zokuvelisa nge-fieldbus kunye nabalawuli be-air-conditioning okanye iinkqubo zokukhanyisa. .Ezi nkqubo ezinobuthathaka zinokukhuselwa kuphela ngumbono wokhuseleko olubanzi.Kulo mxholo, ukusetyenziswa ngokulungelelanisiweyo kwezixhobo zokukhusela zokunyuka (umbane wangoku kunye nababambeli bokunyuka) kubaluleke kakhulu.

Umsebenzi wababambeli bangoku bombane kukukhupha amandla aphezulu ngaphandle kokutshatyalaliswa.Zifakwe ngokusondeleyo ngokunokwenzeka kwindawo apho inkqubo yombane ingena kwisakhiwo.Ii-Surge arresters, nazo, zikhusela izixhobo ze-terminal.Zifakwe ngokusondeleyo kangangoko kunokwenzeka kwisixhobo sokukhuselwa.

Ngosapho lwayo lweRed/Line yemveliso yeenkqubo zonikezelo lwamandla kunye nosapho lwemveliso yeYellow/Line kwiinkqubo zedatha, i-THOR ibonelela ngezixhobo zokukhusela ezihambelanayo.Iphothifoliyo yeemodyuli ivumela ukuphunyezwa kweendleko eziphuculweyo zeengcamango zokukhusela kuzo zonke iintlobo zesakhiwo kunye nobukhulu bofakelo.
