Isixhobo soKhuseleko lwe-TRS-A Surge

Inkcazelo emfutshane:

Uluhlu lwe-TRSA lwesixhobo sokukhusela utyando luhlangabezana neemfuno zomgangatho we-IEC61643 weklasi yokuqala yokubamba umbane. Xa isetyenziswe kunye nesigaba sokugqibela sombane-ukunciphisa umbane wokubamba umbane, isibambisi sombane esinamanqanaba amabini sinokufakwa kunye. Ngenxa yoyilo loyilo olutywiniweyo ngokukodwa, akuyi kubakho arc yokuvuza nangexesha lokusebenza.

TRS-A SPD

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.

Isixhobo sokukhusela umbane kwinqanaba lokuqala sinokukhupha umbane othe ngqo, okanye ukhuphe amandla amakhulu aqhutywe xa umbane wokuhambisa umbane ubethelwa ngokuthe ngqo ngumbane. Kwiindawo apho ukubetha kombane okuthe ngqo kunokuthi kwenzeke, ukhuseleko lombane lwe-CLASS-I kufuneka lwenziwe.

Uluhlu lwe-TRS-A uhlobo lwe-1 SPDs lukhoyo lunomthamo we-impulse wangoku we-15kA, 25KA, 50KA kwisigaba esisodwa okanye ulungelelwaniso lwesigaba se-3 kunye neentlobo ezahlukeneyo zombane ukwenzela ukukhusela naluphi na uhlobo lwenkqubo yokubonelela ngombane.

I-THOR Uhlobo lwe-1 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-10/350 μs waveform.
