Waa maxay nooca tamarta soo noqnoqda ee dhexdhexaadka ah oo buuxin karta shuruudaha foornada dhalaalidda induction?
1 The output power requirements of the foornada dhalinta dhalaalaysa for the thyristor intermediate frequency power supply.
Awoodda wax-soo-saarka tamarta soo noqnoqda ee thyristor dhexdhexaadka ah waa inay buuxisaa awoodda ugu badan ee foornada dhalaalka induction, iyo awoodda wax soo saarka si fudud ayaa loo hagaajin karaa. Tani waa sababta oo ah nolosha qulqulka foornada dhalaalka induction badanaa waxay ku saabsan tahay tobanaan foorno waana ay dhaawacdaa. Foornada foornada qashinka ah waa in dib loo dhisaa, ka dib marka la dhiso foornada cusub ee foornada, waa in lagu sameeyaa foorno awood yar leh. Sida caadiga ah, foornada waxay ka bilaabataa 10-20% awoodda la qiimeeyay, ka dibna waxay kordhisaa awoodda 10% wakhtiyada caadiga ah ilaa awooda la qiimeeyo. Intaa waxaa dheer, habka foornada, marka kharashka la dhalaaliyo, ka kooban kharashka waa in la tijaabiyaa. Inta lagu jiro tijaabada, si looga hortago in kharashka dhalaalayo oo uu si xoog leh u karkariyo, sahayda soo noqnoqda ee dhexdhexaadka ah waa in ay yareysaa awoodda wax soo saarka si ay u ilaaliso diirimaadka. Marka la eego xaaladda kor ku xusan, waxaa loo baahan yahay in tamarta soo noqnoqda dhexdhexaadka ah ee thyristor si fudud loogu hagaajin karo 10% -100% awoodda wax soo saarka ee la qiimeeyay. Foornada diathermic ee loo isticmaalo been-abuurka ma laha hab wax lagu dubto.
2 Shuruudaha soo noqnoqda soo-saarka foornada dhalaalka induction ee tamarta soo noqnoqda dhexdhexaadka ah ee thyristor.
Xidhiidhka ka dhexeeya waxtarka korantada iyo inta jeer ee foornada dhalaalka induction waa mid la xidhiidha. Laga bilaabo waxtarka korantada, inta jeer ee wax soo saarka tamarta soo noqnoqda ee thyristor dhexdhexaad ah ayaa la go’aamin karaa. Tusaale ahaan, waxaan ugu yeernaa inta jeer een fo. Inductor-ku dhab ahaantii waa gariiradda wax-soo-saarka, si loo magdhabo awoodda fal-celinta gariiradda, capacitor-ku waxa uu ku xidhan yahay is barbar socda labada daraf ee gariiradda, kaas oo ka kooban wareegga oscillating LC. Marka inta jeer ee soo-saarka f ee inverter-ka thyristor uu la mid yahay inta jeer ee oscillation dabiiciga ah ee foornada foornada dhalaalaysa ee induction, ka dibna qodobka awoodda wareegga wuxuu la mid yahay 1. Awoodda ugu badan ayaa laga heli doonaa foornada dhalaalka induction. Waxaa laga arki karaa kor ku xusan in inta jeer ee oscillation dabiiciga ah ee loop la xiriiriyo qiyamka L iyo C. Guud ahaan, qiimaha capacitor magdhow C waa go’an, halka inductance L isbedel ay sabab u tahay isbedelka of isku-dhafka permeability ee walxaha foornada. Isku-dheelitirnaanta μ ee birta foornada qabow aad bay u weyn tahay, markaa inductance L waa weyn tahay, marka heerkulka birta uu ka sarreeyo barta Curie, isku-dhafka permeability μ=1 ee birta, markaa inductance L ayaa hoos u dhacda, markaa foornada dhalaalaysa induction loop Inta jeer ee oscillation dabiiciga ah fo waxa uu ka beddeli doonaa hoose ilaa sare. Si loo sameeyo foornada dhalaalidda induction had iyo jeer u hesho awoodda ugu badan inta lagu jiro habka dhalaalidda, tani waxay u baahan tahay in soo-saarka f ee tamarta soo noqnoqda dhexdhexaadka ah ee thyristor ay bedeli karto isbeddelka fo, oo had iyo jeer sii joogtaynta joogtada si toos ah.
3 Shuruudaha kale ee tamarta soo noqnoqda ee thyristor.
Tani waa sababta oo ah marka kharashka foornada uu dhalaalayo, mar haddii korontadu ay xumaato inta jeer ee dhexdhexaadka ah, qoloftu waxay waxyeeloobi doontaa xaalado daran. Sidaa darteed, tamarta soo noqnoqda ee thyristor dhexdhexaad ah ayaa looga baahan yahay inay u shaqeyso si la isku halleyn karo, sidoo kale waa inay lahaataa lagama maarmaanka u ah ilaalinta xaddidaadda xaddidan ee hadda jirta, ilaalinta xad-dhaafka ah iyo ilaalinta hadda, iyo gooynta biyaha. Ilaalinta, iyo aaladaha kale ee ilaalinta tooska ah. Intaa waxaa dheer, waxaa loo baahan yahay in tamarta soo noqnoqda dhexdhexaadka ah ee thyristor ay leedahay heerka guusha bilawga sare, iyo hawlgalka bilawga ah waa inuu noqdaa mid ku habboon.
