Surge Lighting Surge Protective Device 3P 1000 1500VDC

Nws yog cov hlau oxide semiconductor tsis-linear tsis kam nrog ZnO ua cov khoom tseem ceeb. Thaum qhov hluav taws xob siv rau nws ob qhov kawg nce mus txog ib qho nqi, qhov kev tiv thaiv yog qhov rhiab heev rau qhov hluav taws xob. Nws txoj hauv kev ua haujlwm yog sib npaug rau kev sib txuas ntawm ntau lub semiconductor P-Ns. Varistors yog cov yam ntxwv zoo uas tsis yog-linear (I=non-linear coefficient hauv CU), muaj peev xwm loj tam sim no (-2KA/cm2), tsis tshua muaj qhov tsis zoo tam sim no (10-7-10-6A) , thiab tsis tshua muaj hluav taws xob (nyob ntawm seb vim qhov ua haujlwm voltage thiab tam sim no muaj peev xwm ntawm varistor, lub sij hawm teb rau instantaneous overvoltage yog ceev (~10-8s), thiab tsis muaj freewheeling.

Cov kev tsis sib xws ntawm varistors feem ntau suav nrog: varistor voltage (ie switching voltage) UN, reference voltage Ulma; residual voltage Ures; residual voltage ratio K (K=Ures/UN); siab tshaj plaws txaus peev Imax; dej ntws tam sim no; lub sij hawm teb.

Cov kev siv ntawm varistor yog: varistor voltage: UN Ntau dua los yog sib npaug rau [(√2 × 1.2)/0.7] U0 (U0 yog qhov ntsuas voltage ntawm industrial zaus fais fab mov)

Yam tsawg kawg siv hluav taws xob: Ulma Ntau dua lossis sib npaug rau (1.8-2) Uac (siv raws li DC cov xwm txheej)

Ulma Ntau dua los yog sib npaug rau (2.2-2.5) Uac (siv nyob rau hauv AC tej yam kev mob, Uac yog AC ua hauj lwm voltage)

Qhov siab tshaj qhov siv hluav taws xob ntawm varistor yuav tsum tau txiav txim siab los ntawm kev tiv thaiv hluav taws xob tiv thaiv hluav taws xob, thiab qhov seem ntawm qhov hluav taws xob ntawm varistor yuav tsum qis dua qhov poob voltage theem ntawm cov khoom siv hluav taws xob tiv thaiv, piv txwv li (Ulma) max tsawg dua lossis sib npaug. rau Ub/K, saum toj no Hauv cov qauv, K yog qhov seem voltage piv, thiab Ub yog qhov poob voltage ntawm cov khoom tiv thaiv.
