I-varistor idlala indima ebalulekileyo kwisiphaluka.Xa i-overvoltage isenzeka phakathi kwezigaba ezibini ze-varistor, iimpawu ze-varistor zingasetyenziselwa ukubethelela i-voltage kwixabiso le-voltage esisigxina, ukwenzela ukucinezela i-voltage kwisekethe, ukukhusela isiphaluka esilandelayo.
Ke ngaba uyazi ukuba yintoni na la magama: i-voltage yegama, i-varistor voltage, i-residual voltage ratio, ukumelana ne-insulation, umthamo wangoku, kunye nentsingiselo yangoku yokuvuza kwii-varistors?Ukuba awuyazi, funda eli nqaku ukuze ufunde.
1. I-Nominal voltage (V): Eyaziwa nangokuthi i-voltage elinganisiweyo, ibhekisela kwixabiso lombane kwi-varistor xa i-DC current ye-1m idluliswa.
2. I-Varistor voltage: Ixabiso lombane elilinganiswe kwiziphelo zombini ze-varistor xa i-current ethile (1mA DC) ihamba nge-varistor.
3. Umlinganiselo we-voltage eseleyo: Xa i-current through varistor ixabiso elithile, i-voltage eveliswa kuzo zombini iziphelo ze-varistor ibizwa ngokuba yi-voltage eseleyo yeli xabiso langoku.Umlinganiselo wamandla ombane oshiyekileyo ngumlinganiselo wamandla ombane ashiyekileyo kumbane wegama.
4. Ukuxhatshazwa kwe-insulation: ukuxhatshazwa kwe-DC kwe-insulator phantsi kweemeko ezichaziweyo.Ukuxhatshazwa kwe-insulation ye-varistor kubhekisela kwixabiso lokumelana phakathi kwentambo ekhokelayo (iphini) ye-varistor kunye ne-insulating surface ye-resistor.
5. Umthamo wokuhamba (kA): ixabiso eliphezulu langoku elivunyelwe ukuba lidlule kwi-varistor phantsi kwexesha elichaziweyo kunye nenani lamaxesha, phantsi kokusetyenziswa kwe-standard impulse current.
6. Ukuvuza kwangoku (mA): kubhekiselele kumbane ojikelezayo kwi-varistor phantsi kobushushu obuchaziweyo kunye ne-peak DC yombane.
Ukuqonda imigaqo ekhethekileyo yee-varistors kunokunceda xa kuziwa ekukhetheni i-varistors.Khetha umenzi othembekileyo xa uthenga i-ceramic capacitors unokuphepha iingxaki ezininzi ezingeyomfuneko.JYH HSU (okanye iDongguan Zhixu Electronics)ayinayo kuphela imodeli epheleleyo ye-ceramic capacitors enomgangatho oqinisekisiweyo, kodwa inikezela ngokungenaxhala emva kokuthengisa.Wamkelekile ukuba uqhagamshelane nathi ukuba ufuna izixhobo ze-elektroniki.
