Uhlalutyo lwesizathu sokutshiswa kwe-Thyristor

Ngexesha lokusetyenziswa kwesithando somlilo esiphakathi, ukutshisa kwe-thyristor kaninzi kwenzeka, okuhlala kucaphukisa abasebenzi bokugcinwa kwesithando somlilo esiphakathi, kwaye ngamanye amaxesha abakwazi ukuwacombulula.Ngokweerekhodi zokugcinwa kwesithando somlilo esiphakathi iminyaka emininzi, idatha inokubonwa ngezantsi ukuze ibhekiswe ngabasebenzi bokulondoloza.

1.Ijacket yokupholisa amanzi ye-inverter thyristor iyanqunyulwa okanye umphumo wokupholisa uyancipha, ngoko ke umkhono wokupholisa amanzi kufuneka utshintshwe.Ngamanye amaxesha kwanele ukujonga ubuninzi bamanzi kunye noxinzelelo lwejacket yokupholisa amanzi, kodwa kaninzi ngenxa yengxaki yomgangatho wamanzi, umaleko wesikali unamathele eludongeni lwejacket yokupholisa amanzi.Ngenxa yokuba isikali luhlobo oluthile lwe-thermal conductivity differential nangona kukho ukuhamba okwaneleyo kokuhamba kwamanzi, umphumo wokutshatyalaliswa kobushushu uyancipha kakhulu ngenxa yokuhlukaniswa kwesikali.Indlela yokugweba kukuba amandla asebenza kumandla amalunga nemizuzu elishumi ngaphantsi kwelo lexabiso lokuphuphuma.Emva koko amandla ayeka ngokukhawuleza, kwaye umbindi wento elawulwa yisilicon yachukumisa ngokukhawuleza ngesandla emva kokuyeka.Ukuba ivakala ishushu, impazamo ibangelwa sesi sizathu.

2.Unxibelelwano phakathi kwegroove kunye nomqhubi luhlwempu kwaye luphukile.Jonga i-slot kwaye udibanise iingcingo, kwaye uziphathe ngokweyona meko.Xa ucingo lokuqhagamshelwa kweshaneli inemeko yokubopha yoqhagamshelwano olubi okanye umgca ophukileyo, ukunyuka kwamandla kwixabiso elithile kuya kuvelisa isenzeko somlilo, esichaphazela umsebenzi oqhelekileyo wezixhobo, ezikhokelela ekukhuselweni kwezixhobo.Ngamanye amaxesha i-overvoltage edlulayo iveliswa kuzo zombini iziphelo kwi-thyristor ngenxa yokukhathala.It ukhuseleko overvoltage kade kakhulu, iya bum i element thynstor.Ukugqithiswa kwe-overvoltage kunye ne-overcurrent ihlala isenzeka ngaxeshanye.

3.I-instantaneous burr voltage ye-thyristor iphezulu kakhulu xa i-thyristor iguqulwa.Kwisekethe ephambili yobonelelo lwamandla ombane ophakathi, umbane oguqukayo wesigaba se-burr ufunxwa kukuxhathisa kunye nokufunxa.Ukuba i-resistor kunye ne-capacitor circuit zivuliwe kwi-absorption circuit iya kubangela ukuba i-voltage ye-reverse burr iphakame kakhulu kwaye itshise i-thyristor.Kwimeko yokusilela kwamandla, sisebenzisa itheyibhile ye-WAN Xiu ukulinganisa i-absorpti kwi-resistance kunye ne-capacitance ye-absorption capacitor, ukuze kuqinisekiswe ukuba kukho impazamo kwisekethe yokumelana ne-resistance capacitance.

4.Umthwalo unciphisa i-sulation ye-grou nd: ukugquma kwe-loop yomthwalo kuyancipha, kubangela ukuba umthwalo uvuthe phakathi komhlaba, uphazamise ixesha lokuqalisa i-pulse okanye wenze i-voltage ephezulu kuzo zombini iziphelo ze-thyristor kwaye ukutshisa i-thyristor element.

I-5.I-Pulse trigger circuit fault: Ukuba i-pulse ye-trigger ilahlekile ngokukhawuleza xa ifowuni isebenza, iya kubangela isiphaluka esivulekileyo se-inverter kwaye ivelise i-voltage ephezulu ekupheleni kwesiphumo sonikezelo lwamandla ombane ophakathi kwaye itshise i-thyristor element.Olu hlobo lwesiphoso luvame ukubunjwa kwe-inverter pulse kunye nephutha lesekethe yokuphuma.Inokuthi ihlolwe yi-oscilloscope, kwaye inokuba luqhagamshelwano olubi lwe-inverter lead wire, kwaye inokugungqa idibaniso yocingo ngesandla kwaye ifumane indawo yempazamo.

I-6.Isixhobo sivula xa umthwalo usebenza: Xa isixhobo sisebenza ngamandla aphezulu, ukuba umthwalo ngokukhawuleza ukwisiphaluka esivulekileyo, i-silicon elawulwayo iya kutshiswa ekupheleni kokuphuma.

7. Umthwalo omfutshane ujikelezwe xa izixhobo zisebenza: Xa izixhobo zisebenza ngamandla aphezulu, ukuba umthwalo ujikeleza ngokukhawuleza, uya kuba nempembelelo enkulu yesekethe yangoku kwi-SCR: kwaye ukuba intshukumo yokukhusela yangoku. ayinakukhuselwa, izinto ze-SCR ziya kutshiswa.

I-8.Ukukhuselwa kwenkqubo yokungaphumeleli (ukungaphumeleli kokukhusela): Ukhuseleko lwe-SCR ikakhulu luxhomekeke kwinkqubo yokukhusela.Ukuba kukho ukusilela kukhuseleko) kwinkqubo, isixhobo asiqhelekanga kancinci emsebenzini waso, nto leyo eya kuzisa ingxaki kukhuseleko lwe-SCR.Ngoko ke, kubalulekile ukujonga inkqubo yokukhusela xa i-SCR ivutha.

Ukungaphumeleli kwenkqubo yokupholisa ye-9.SCR: I-Thyristor ishushu kakhulu emsebenzini kwaye ifuna ukupholisa ukuqinisekisa ukusebenza kwayo okuqhelekileyo.Ngokubanzi, zimbini iindlela zokupholisa isilungisi esilawulwa yisilicon: enye kukupholisa amanzi kwaye enye kukupholisa umoya.Ukupholisa amanzi kusetyenziswa kakhulu, kwaye ukupholisa umoya kusetyenziswa kuphela unikezelo lwamandla ngaphantsi kwe-100KW.Ngokuqhelekileyo, isixhobo esiphakathi se-frequency kunye nokupholisa kwamanzi sixhotyiswe ngesekethe yokukhusela uxinzelelo lwamanzi, kodwa ngokusisiseko kukukhusela impembelelo epheleleyo.Ukuba amanzi athile avaliwe, akanakukhuselwa.

10.I-reactor isengxakini: Ukuvutha kwangaphakathi kwe-reactor kubangela ukuba icala le-cur nt lecala elikwi-verer liphazamiseke.
