Khusela izixhobo zombane, ukuqala nge-SPD yokukhusela umkhuseli!

Intshayelelo

SPD surge mkhuseliluhlobo olutsha lwemveliso yokukhusela umbane eyenziwe ngumkhuseli wokunyuka kunye nesekethe ye-elektroniki, esetyenziswa ikakhulu ukukhusela izixhobo zombane ekubetheni umbane kunye nombane.Umgaqo osebenzayo womkhuseli wokutyanda we-SPD kukukhawulela umbane wangoku nge-SPD ukuya kuluhlu oluthile ngokusebenzisa ityhubhu yokunciphisa umbane kunye nediode ngaphakathi.SPD.

Iimpawu zeSPD surge abakhuseli:

I-1, Ukunciphisa umbane we-stroke yangoku (ekwabizwa ngokuba ngumbane wokukhupha ngoku);

2, Ukunciphisa amandla ombane wepulse (okt ukukhupha amandla ombane);

3, i-Electromagnetic Pulse (EMI) eneSitrowuli soMbane esiThintelweyo;

4, Ukunciphisa amandla enziwe ngombane;

5, Ukukhusela into kumonakalo obangelwa kukubetha ngokuthe ngqo kombane okanye ukuphazamiseka kwe-electromagnetic;

6, Ukunciphisa i-over-voltage eyenziwe kwisekethe (i-voltage induction induction okanye i-over-voltage induced).

Ububanzi beSicelo

SPD surge mkhuseli uyakhuselaizixhobo zombane ukusuka overvoltage umbane kunye nezinye overvoltage ngequbuliso kunye overcurrent kwinkqubo yamandla.Inokukhusela izixhobo zombane kwi-overvoltage kwaye iqinisekise ukhuseleko lomntu.

Abakhuseli be-SPD Surge basebenza kwezi ndawo zilandelayo:

(1) Indawo yokungenisa umbane kwizakhiwo eziphakamileyo;(2) I-inlet ye-optical cables yonxibelelwano kunye neentambo zomqondiso kwiintambo zombane;(3) I-inlet yeebhokisi zokuhambisa kunye neekhabhinethi;(4) I-inlet ye-cable cores kunye neengcingo eziphezulu;(5) Indawo yokufaka umbane kwiinkqubo zekhompyutha;kunye (6) I-inlet yesixhobo sokutshintsha kwizakhiwo siya kuxhotyiswa ngezikhuseli zokunyuka ze-SPD ukuba isixhobo sokutshintshela siqhutywa ngumbane we-AC, ngelixa indawo yokungena yombane we-AC iya kuxhotyiswa ngezikhuseli zokushukuma ze-SPD.

Isalathiso sokusebenza

I-1, Xa isibambi se-SPD sisebenza njengesiqhelo, akusayi kubakho nxibelelwano lubi, ngaphezulu kombane okanye ngaphantsi kombane.

I-2, Xa i-SPD i-surge arrester ikwintsebenzo eqhelekileyo, akukho mpembelelo enkulu yangoku edlula kwi-surge arrester.

3, Umthamo wangoku we-SPD arrester awuyi kuba ngaphantsi kwamaxesha angama-1.2 omthamo olinganisiweyo wangoku wesixhobo esikhuselweyo, kwaye awuyi kuba ngaphantsi kwe-1000A (okanye i-voltage elinganisiweyo ayiyi kuba ngaphantsi kwe-10 / 350V);ukuba umthamo wangoku wezixhobo ezikhuselweyo zingaphezulu kwe-10/350V, nceda uqhagamshelane nathi ukuze ukhethe amandla akhoyo afanelekileyo ngaphakathi koluhlu olukhuselekileyo nolusebenzayo.
