Malunga nesizathu sokutshiswa kwe-varistor

Kwisekethe, indima ye-varistor yile: okokuqala, ukukhuselwa kwe-overvoltage;okwesibini, iimfuno zokuxhathisa umbane;okwesithathu, iimfuno zovavanyo lokhuseleko.Ke kutheni i-varistor itshisa kwisekethe?Siyintoni isizathu?

I-Varistors ngokubanzi idlala indima ekukhuselweni kwamandla ombane kwiisekethe, kwaye inokusetyenziswa kunye neefuse zokubetha umbane okanye olunye ukhuseleko lombane.Ngokuqhelekileyo isetyenziselwa ukukhusela umbane.Xa i-overvoltage isenzeka, i-varistor iya kuchithwa kwaye isiphaluka esifutshane siya kwenzeka, ukwenzela ukuba i-voltage kwiziphelo zombini ze-varistor iya kunyanzeliswa kwindawo ephantsi.Kwangaxeshanye, i-overcurrent ebangelwa yi-short circuit iya kutshisa i-fuse yangaphambili okanye iNyanzelise ukutshintshelwa komoya ukuba ihambe, ngaloo ndlela inqumle umbane ngenkani.Ngokuqhelekileyo, inempembelelo encinci kwezinye izinto ze-elektroniki emva komonakalo, jonga nje amacandelo esekethe aqhagamshelwe kuyo.Kwimeko yomonakalo wokubhoboza, i-fuse iya kuvuthela.

Xa i-voltage ingaphantsi kwe-voltage elinganisiweyo ye-varistor, ukuchasana kwe-varistor akupheli kwaye akukho mpembelelo kwisiphaluka.Xa i-voltage kwisiphaluka idlula i-voltage ye-varistor, ukuchasana kwe-varistor kuya kuhla ngokukhawuleza, okuya kudlala indima ye-shunt kunye nokunciphisa i-voltage, kwaye i-fuse kwisiphaluka esifanayo iya kubethwa ukuze idlale indima yokukhusela.Ukuba akukho fuse kwisekethe, i-varistor iya kuqhuma ngokuthe ngqo, yonakaliswe kwaye ingaphumeleli, ilahlekelwe yimpembelelo yayo yokukhusela, kwaye ibangele ukuba isiphaluka esilandelayo sitshise.
Ezi zizathu zithathu zingentla zizizathu ezenza ukuba i-varistor itshise kwisiphaluka.Ingqwalasela ekhethekileyo kufuneka ihlawulwe ekusebenzeni kwixesha elizayo ukuphepha umonakalo kwi-capacitor.
