Isitshalo esingekho sokulungiswa kwe thyristor PIS

Isithwiti sokugcina ngokungcolile sika thyristor se-PIS sisebenzisa inkokhelo ye-thyristors ukulawula ngokucacile ukwahlukaniswa kwemali. Sichaza futhi sikhanya lapho uvolti liyagcuka kwi-zero point, bese lithola futhi licindezela lapho ikhurrenti liyagcuka kwi-zero point. Lokhu kungathi kungani kakhulu kweqondo lokuhlelwa kungaba yini (inductive, capacitive) noma ngokuphelele kwezimali (purely resistive), akukho moya othintayo kwegridi lapho licindezelwa, futhi ubudlelwane bokugcina bakhubeka ngokukhulu.
Ithumela i-intela yokuxhumana ehlukile, elimina ubidingo be-wiring wesibili. I-cable yenethiwekhi iyafakwa ngqo kufakwa, ithi kweqile kwenethiwekhi futhi ithi kuchazwe, futhi idatha yokusebenzisa iswitch ingabonakali futhi ingasebenzi ngokujulile.

ipharamitha yemikhina

◆ Ukuqashwa kwezinhlelo yokuphepha ngokusebenza kwezinhlelo yokuphepha okuningi ukungena kwezimali ezingenakukhona ukusebenza ngokuzenzakalelayo kumaqondo okungu-environment yokungena kwezimali;

Inikezwe amachip amadoda obudlelwane, isebenza kuhumshu oluphezulu lwama-24MHZ, nezinhloso zokukhangela nokubala okuphezulu, futhi amanye amathaski angakwehliswa ngokushesha.

◆ Imithwadi yokuthuma yohambo oludluliselwe, ukuthuma okuphezulu kohambo oluphezulu, ukugcina ukuthi izithyristor zilayele ngokushesha futhi zingene ngokugcdeepa;

◆ Inethiwekhi ye-LCR, ukulawula ukusebenza okuphephawuwe kwezithyristor;

◆ Hlela imoduli yezithyristor ehambelana nezincazelo, ukwesekwa kwezincazelo ezingaphezulu emva kokususa ikhaphasithela, futhi ukukhetha izinkinobho ezingemvelo ze-dv/dt ne-di/dt ukugcina ukusebenza okuphephawuwe kwezithyristor kumaqondo aphakeme kakhulu;

◆ Ukushisa kwe-fan DC, ukulungisa uhla, ukulungiswa ngokuzenzakalelayo hhayi ukulingana nezinga lokushisa okudingekayo, ukushisa okuphephawuwe futhi ukuba yilapho kudinga ukuphathwa ngemva kwekhala elide;

◆ Ukugcina ngokushesha kwekurenti yasebenzelo (ikhetho) kunye nesibuko sokuvula, kunye nokugcina okuphumelelayo;

◆ Ukuvula okupheleleyo kwi-zero-crossing, ukuvula ngokunxantathu, ukuvula okungaphantsi kwekurrenti, ukulawula ikurrenti yokuqalisa ≤ 2.5 amaxesha a- In;

◆ Ukusebenza ngokushesha engenazo mithi, ukulandelana ngokucacileyo, kunye nokugcina iphakamiso yasekugqibeleni.

◆ Ukuxhuma ngokwekhabhili yenethiwekhi, ukusebenza ngokuzenzekelayo nenkqubo yokulawula, ukugcina idatha, kunye nokusebenza okuchanekileyo kunye nokwaziwa kwegca.

• Imisebenzi yekhankatha

◆ Intemperethura yomoya: -25 ℃ ukuya +40 ℃;

◆ Umgciphelelo wamanzi: ≤ 90% e 25 ℃;
