Izixazululo zezakhiwo.

Ukunyuka - ingozi elinganiselweUkwenyuka kuyingozi evame ukubukelwa phansi. Lawa ma-voltage pulses (ama-transients) athatha isekhondi elilodwa kuphela abangelwa ukushaya kombani okuqondile, okuseduze nokukude noma ukushintsha imisebenzi yensiza yamandla.Umbani oqondile naseduze Umbani oqondile noma oseduze uwukushaya kombani esakhiweni, eduze kwaso noma emigqeni engena esakhiweni (isb., isistimu yokuphakelwa kwamandla kagesi aphansi, izintambo zezokuxhumana kanye nedatha). I-amplitude namandla aqukethwe emisinga yomfutho ewumphumela kanye ne-impulse voltages kanye ne-electromagnetic field ehambisanayo (LEMP) kusongela kakhulu uhlelo ukuthi luvikeleke. Umsinga wombani obangelwa ukushaya kombani oqondile ungene esakhiweni ubangela ukukhuphuka kwamandla okungamavolthi ambalwa angu-100,000 kuwo wonke amadivaysi anomhlaba. Ukwenyuka kubangelwa ukwehla kwamandla kagesi ku-impedance ye-earthing evamile kanye nomphumela wokukhuphuka kwesakhiwo maqondana nemvelo. Lokhu ukucindezeleka okuphezulu kakhulu kumasistimu kagesi ezakhiweni. Ngokungeziwe ekwehleni kwe-voltage ku-impedance ye-earthing evamile, ama-surges ayenzeka ekufakweni kukagesi wesakhiwo kanye namasistimu axhunyiwe namadivayisi ngenxa yomphumela wokungeniswa kwenkambu yombani kagesi. Amandla alokhu kukhuphuka okubangelwa kanye nemisinga yomfutho ewumphumela aphansi kunaleyo yombani oqondile wamanje. Umbani ushaya kude Umbani ushaya 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. Ukushintsha imisebenzi Ukushintsha 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. Ukuvikelwa kokunikezwa kwamandla kanye nezinhlelo zedatha Izimo ezibhubhisayo ezakhiweni zokuhlala, zamahhovisi nezokuphatha kanye nasezimbonini zezimboni kungenzeka zenzeke, ngokwesibonelo, ohlelweni lokuphakelwa kukagesi, uhlelo lobuchwepheshe bolwazi kanye nohlelo lwezingcingo, izinhlelo zokulawula izindawo zokukhiqiza ngebhasi kanye nezilawuli ze-air-conditioning noma izinhlelo zokukhanyisa. . Lezi zinhlelo ezibucayi zingavikelwa kuphela umqondo wokuvikela obanzi. Kulo mongo, ukusetshenziswa okudidiyelwe kwemishini yokuvikela ukukhuphuka (izibambisi zombani nezivimbela ukukhuphuka) kubaluleke kakhulu. Umsebenzi wokubopha umbani wamanje ukukhipha amandla aphezulu ngaphandle kokubhujiswa. Zifakwe eduze ngangokunokwenzeka kuze kube yilapho uhlelo lukagesi lungena esakhiweni. Izibambisi ezihlinzayo zona zivikela izinto ezisetshenziswayo. Zifakwe eduze ngangokunokwenzeka kumishini okufanele ivikelwe. Ngomndeni wayo womkhiqizo oBomvu/Ulayini wezinhlelo zokuphakela amandla kanye nomndeni wayo womkhiqizo oYellow/Line wezinhlelo zedatha, i-THOR inikeza amathuluzi okuvikela okuhlinzwa avumelanisiwe. Iphothifoliyo ye-modular ivumela ukuqaliswa okuthuthukisiwe kwezindleko kwemiqondo yokuvikela yazo zonke izinhlobo zesakhiwo nosayizi bokufaka.
