Isixhobo sokuKhusela i-TRS6 Surge

Inkcazelo emfutshane:

Umgaqo osebenzayo wesixhobo sokukhusela utyando: Ababambeli botyando oluchazwa ngokuqhelekileyo njenge-SPDs (iZixhobo zoKhuseleko lwe-Surge), zizixhobo ezenzelwe ukukhusela iinkqubo zombane kunye nezixhobo ngokuchasene nokugqithisa okwexeshana kunye nokugqithiswa kwe-impulse ezifana nezo zibangelwa ukubetha kombane kunye nokutshintsha kombane. Umsebenzi wabo kukuguqula ukukhutshwa okanye i-impulse current eyenziwa ngokugqithiswa komhlaba / emhlabeni, ngaloo ndlela ikhusela izixhobo ezisezantsi. IiSPD zifakwe ngokunxuseneyo ne...

Umgaqo osebenzayo wesixhobo sokukhusela utyando: I-surge arresters ngokuqhelekileyo ichazwa njenge-SPDs (iZixhobo zoKhuseleko lwe-Surge), zizixhobo ezenzelwe ukukhusela iinkqubo zombane kunye nezixhobo ngokuchasene nokugqithisa okwexeshana kunye nokunyanzeliswa kwezinto ezifana nezo zibangelwa ukubetha kombane kunye nokutshintsha kombane. Umsebenzi wabo kukuguqula ukukhutshwa okanye i-impulse current eyenziwa ngokugqithiswa komhlaba / emhlabeni, ngaloo ndlela ikhusela izixhobo ezisezantsi. I-SPDs ifakwe ngokuhambelana nomgca wombane ukuze ukhuselwe. Kwi-voltage ephakathi, ifaniswa nesekethe evulekileyo kwaye ine-impedance ephezulu ekupheleni kwayo. Xa kukho i-overvoltage, le impedance iwela kumaxabiso aphantsi kakhulu, ukuvala isekethe emhlabeni / emhlabeni. Emva kokuba i-overvoltage iphelile, i-impedance yabo iphakama kwakhona ngokukhawuleza kwixabiso lokuqala (eliphezulu kakhulu), libuyela kwiimeko ezivulekileyo ze-loop. Uhlobo lwesi-2 SPD yeyona nkqubo yokhuseleko iphambili kuzo zonke ufakelo lombane ophantsi kombane. Ifakwe kwi-switchboard nganye yombane, ikhusela ukusasazeka kwe-overvoltages kwiifakelo zombane kwaye ikhusela imithwalo. Uhlobo lwe-2 izixhobo zokukhusela (SPDs) zenzelwe ukukhusela ukufakwa kombane kunye nezixhobo ezibuthathaka ngokuchasene nokunyuka okungathanga ngqo kunye nokuqinisekisa izinga lokukhusela eliphantsi (Phezulu). Izixhobo ezikhuselayo zodidi lwe-2 zibonelela ngokhuseleko olusebenzayo kwezi zinto ziguquguqukayo zokuphazamiseka. Ingaba kwindawo yoshishino okanye kwisakhiwo sokuhlala, uhlobo lwe-2 lokukhusela luqinisekisa ukhuseleko olusisiseko lofakelo kunye nezixhobo zakho. Uluhlu lwe-TRS6 uhlobo lwe-2 SPDs lufumaneka lunamandla okukhutshwa kwe-80kA, i-100KA kwisigaba esisodwa okanye kwi-3-phase yoqwalaselo kunye neentlobo ezahlukeneyo zombane ukwenzela ukukhusela naluphi na uhlobo lwenkqubo yokubonelela ngombane. I-THOR Uhlobo lwe-2 ye-DIN-umzila we-SPD iimpawu zibonelela ngokuphendula ngokukhawuleza kwe-thermal kunye nomsebenzi ogqibeleleyo wokunqunyulwa kunye nokubonelela ngokhuseleko olukhawulezayo noluthembekileyo kwiinkqubo ezahlukeneyo zonikezelo lwamandla.Kwaye amandla ayo okukhupha ngokukhuselekileyo ngoku kunye ne-8/20 μs waveform. Eyakhelwe ngesiphoso sefestile kunye noqhagamshelwano olukhethiweyo lwe-alam ekude, inokubeka iliso kwimo yokusebenza ye-SPD ngokwayo.
