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 umbane ngokuthe ngqo okanye okufutshane kukubetheka kombane kwisakhiwo, ekusondeleni kwayo okanye kwimigca engena kwisakhiwo (umzekelo, inkqubo yonikezelo lwamandla aphantsi-voltage, unxibelelwano kunye nemigca yedatha). 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 umbane kude are lightning strikes far away from the object to be protected, in the medium-voltage overhead line network or in its close proximity as well as cloud-to-cloud discharge. Ukutshintsha imisebenzi Ukutshintsha imisebenzi of power utilities cause surges (SEMP - Switching Electromagnetic Pulse) of some 1,000 volts in electrical systems. They occur, for example, when inductive loads (e.g. transformers, reactors, motors) are switched off, arcs are ignited or fuses trip. If power supply and data lines are installed in parallel, sensitive systems may be interfered with or destroyed. Ukukhuselwa konikezelo lwamandla kunye neenkqubo zedatha Ukutshatyalaliswa okutshabalalisayo kwizakhiwo zokuhlala, iofisi 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. Ngentsapho yayo yemveliso eBomvu / yoMlayini kwiinkqubo zonikezelo lwamandla kunye nentsapho yemveliso yeYellow / Line kwiinkqubo zedatha, i-THOR inikezela ngezixhobo zokukhusela ezihambelanayo. Iphothifoliyo yeemodyuli ivumela ukuphunyezwa kweendleko eziphuculweyo zeengcamango zokukhusela kuzo zonke iintlobo zesakhiwo kunye nobukhulu bofakelo.
