Umgaqo-siseko wokuSebenza we-Solid State High Frequecy

Oku kubizwa ngokuba yi "solid state high frequency" kungenxa yokuba isebenzisa ii-transistors (MOS field effect transistors okanye IGBT) as the main inverter components.Ngokungafaniyo netyhubhu yokufunxa ihollow(umphandle ugcwele igesi enesidima, ngoko ke unokubizwa ngokuba "yigesi"),i-transistors ziqinile.

I-Solid state high frequency yimveliso ehlaziyiweyo ye-vacuum tube frequency ephezulu, kwaye isekethe yayo ephambili iyafana ne-thyristor medium frequency, kodwa yahlukile kwi-vacuum tube frequency ephezulu. Umgaqo wayo osisiseko uthi: 

Inqanaba lesithathu le-AC (i-380V kunye ne-50HZ rhoqo e-China) iguqulwa ibe yi-voltage eguquguqukayo etyhutyhayo i-DC ngokusebenzisa isekethe yokulungisa (i-SCR okanye i-diode kunye ne-IGBT), le DC iyahluzwa okanye i-flat wave ibe yi-DC egudileyo, kwaye emva koko iye kwi-inverter bridge (usebenzisa i-transistor yamandla amakhulu i-MOSFET okanye i-IGBT) ukuba ibe yangoku ephezulu. Lo mzuzu ophezulu wangoku unikezelwa kwi-tank yesiphaluka umthwalo resonance ingasetyenziselwa ukufudumeza kwentsimbi.Iiyunithi zamandla ebhulorho ye-Inverter ithatha imodyuli yemodyuli.isibini iimodyuli zamandla ziyafana.kodwa inani leemodyuli zamandla ezisetyenzisiweyo ziyahluka ngokuxhomekeke kwisixhobo se-power.Nokuba isixhobo sikhulu okanye sincinci, ulwakhiwo lufana.

Xa kuthelekiswa neetyhubhu zokufunxa ezisebenza ngamaza amaninzi, izibonelelo zezixhobo ezisebenza ngamaza amaninzi ngolu hlobo lulandelayo:

1.Umgangatho wokuwelda okulungileyo: uthelekiso lubonisa ukuba imibhobho yentsimbi edityaniswe sisixhobo sobume obuqinileyo sinobubanzi obudityanisiweyo kunye nobushushu, kunye neebhubhu ezimbalwa zangaphakathi nangaphandle.

2. Ukugcina amandla: uvavanyo lubonisa ukuba iinkcukacha ezifanayo le welder inokugcina ngaphezu kwe-25% yombane xa kuthelekiswa nezixhobo ze-vacuum tube.

3. Ukonga amanzi: ngenxa yokulahleka okuncinci kokuzilahlekela.akufuni manzi okupholisa amaninzi kakhulu.ngoko isebenzisa amanzi angaphantsi kwama-50% ngaphantsi kwesixhobo setyhubhu yokufunxa eneenkcukacha ezifanayo.

4.Ubungakanani obuncinci kunye nobunzima obulula: ngenxa yobukhulu obuncinci bamacandelo aphambili (MOSFET) kwaye akukho balawuli be-welding transformer.filament regulators.matching coils.gate circuits.etc. Ngoko ivolumu iyonke ingaphezulu kwe-50 °/4. encinci kunesixhobo setyhubhu ye-vacuum yeenkcukacha ezifanayo

5.Kulula ukusebenza: akukho mbane, amandla ombane aphezulu akadluli kumakhulu ambalwa eevolthi, ngoko ayisayi kubangela ukwenzakala
