I-varistor idlala indima ebalulekile kumjikelezo.Lapho i-overvoltage yenzeka phakathi kwezigaba ezimbili ze-varistor, izici ze-varistor zingasetshenziswa ukubopha i-voltage enanini le-voltage elilinganiselwe, ukuze kucindezelwe i-voltage kusekethe, kuvikelwe isekethe elandelayo.
Ngakho-ke uyazi ukuthi yini la magama: i-voltage yegama, i-varistor voltage, isilinganiso se-voltage esalayo, ukumelana nokushisa, umthamo wamanje, kanye nencazelo yamanje yokuvuza yama-varistors?Uma ungazi, funda lesi sihloko ukuze ufunde.
1. I-Nominal voltage (V): Eyaziwa nangokuthi i-voltage elinganiselwe, ibhekisela enanini le-voltage kuyo yonke i-varistor lapho i-DC current engu-1m idlula.
2. I-Varistor voltage: Inani le-voltage elilinganiswa kuzo zombili iziphetho ze-varistor lapho i-current ethile (1mA DC) igeleza ku-varistor.
3. I-Residual voltage ratio: Uma i-current ngokusebenzisa i-varistor iyinani elithile, i-voltage ekhiqizwa kuzo zombili iziphetho ze-varistor ibizwa ngokuthi i-voltage esele yaleli nani lamanje.Isilinganiso se-voltage esalayo isilinganiso se-voltage esalayo ku-voltage yegama.
4. Ukumelana ne-insulation: ukumelana kwe-DC kwe-insulator ngaphansi kwezimo ezithile.Ukumelana nokufakwa kwe-varistor kubhekisela enanini lokumelana phakathi kwentambo yokuhola (iphini) ye-varistor kanye ne-insulating surface ye-resistor.
5. Umthamo wokugeleza (kA): inani eliphakeme lamanje elivunyelwe ukudlula i-varistor ngaphansi kwesikhawu sesikhathi esishiwo kanye nenani lezikhathi, ngaphansi kokusetshenziswa kwe-standard impulse current.
6. I-Leakage current (mA): ibhekisela kumanje ogeleza ku-varistor ngaphansi kwezinga lokushisa elishiwo kanye ne-voltage ephezulu ye-DC.
Ukuqonda imigomo ekhethekile ye-varistors kungasiza uma kuziwa ekukhetheni ama-varistors.Khetha umkhiqizi onokwethenjelwa lapho uthenga ama-capacitor e-ceramic angagwema izinkinga eziningi ezingadingekile.I-JYH HSU (noma i-Dongguan Zhixu Electronics)ayinayo kuphela amamodeli agcwele ama-capacitor e-ceramic anekhwalithi eqinisekisiwe, kodwa futhi inikeza ngaphandle kokukhathazeka ngemva kokuthengisa.Siyakwamukela ukuthi usithinte uma udinga izingxenye ze-elekthronikhi.
