Izilumkiso zokukhethwa kunye nokufakwa kwe-thyristor kwi-furnace yokunyibilikisa induction

Unikezelo lwamandla ombane ophakathi luyinxalenye ebalulekileyo yesithando sokunyibilikisa i-induction, kwaye i-thyristor yintliziyo ye-intermediate frequency power supply. Ukusetyenziswa kwayo ngokuchanekileyo kubalulekile ekusebenzeni kwesixhobo. Umsebenzi wangoku we-thyristor ungamawaka amaninzi amps, kwaye i-voltage idla ngokuba ngaphezu kwewaka le-volts. Ukhuseleko olulungileyo lwebhodi yolawulo oluphambili lonikezelo lwamandla ombane oluphakathi kunye neemeko ezilungileyo zokupholisa amanzi ziyimfuneko. Ke ngoko, nantsi izilumkiso zokukhethwa kunye nokufakwa kwe-SCR yesithando somlilo sokunyibilikisa.

Iimpawu zokugqithiswa kwe-thyristor: Umonakalo we-thyristor ubizwa ngokuba yi-breakdown. Ngaphantsi kweemeko eziqhelekileyo zokupholisa kwamanzi, umthamo ogqithisiweyo wangoku unokufikelela ngaphezu kwe-110%, kwaye i-SCR yonakaliswe ngokuqinisekileyo phantsi koxinzelelo. Ukuqwalasela i-voltage yokunyuka, abavelisi bahlala bekhetha amacandelo e-SCR ngokusekelwe kumaxesha ama-4 ombane osebenzayo xa kuveliswa izixhobo. Umzekelo, xa umbane olinganisiweyo wokusebenza wekhabhathi yobonelelo lwamandla ombane ophakathi yi-1750V, amacandelo amabini e-silicon ane-standard voltage ye-2500V akhethwa ukuba asebenze ngokulandelelana, elilingana nombane wokuxhathisa we-5000V.

Uxinzelelo oluchanekileyo lofakelo lwe-SCR: 150-200KG / cm2. Xa isixhobo siphuma kumzi-mveliso, ngokuqhelekileyo sifakelwe umatshini wokushicilela owenziwe ngoxinzelelo olukhulu olwenziwa ngamanzi. Ukusetyenziswa ngesandla kwee-wrenches eziqhelekileyo akukwazi ukufikelela kweli xabiso ngamandla amakhulu, ngoko akukho mfuneko yokuba nexhala malunga ne-thyristor etyunyuziweyo xa ilayishwa ngesandla uxinzelelo; ukuba uxinzelelo lukhululekile, luya kutshisa nge-thyristor ngenxa yokutshatyalaliswa kobushushu obuphantsi.
