Inverter intermediate frequency furnaces must have advantages over parallel intermediate frequency furnaces

1. The thyristor parallel circuit ndi ng’anjo yofanana ya resonance yapakatikati. Panthawi yosungunuka, makamaka kusungunuka kwa aluminiyamu, mkuwa ndi zipangizo zina, katunduyo ndi wochepa kwambiri, ndipo mphamvu yake imakhala yochepa kwambiri, yomwe imakhala ndi zambiri zokhudzana ndi chikhalidwe cha katunduyo, kotero kuti kusungunuka kwake kumathamanga pang’onopang’ono , Zovuta. mu kutenthetsa. The thyristor mndandanda wapakatikati kusungunula ng’anjo amasintha mphamvu kudzera pafupipafupi kusinthasintha kusinthasintha, choncho ndi zochepa amakhudzidwa ndi chikhalidwe cha katundu. Njira yonse ya smelting imakhalabe ndi mphamvu zokhazikika. Chifukwa ndi resonance yotsatizana, ndiye kuti, voteji resonance, voteji ya coil induction ndi yayikulu ndipo pano ndi yaying’ono, kotero Kutayika kwamagetsi ndikochepa.

2. Chifukwa ndi inverter yotsatizana, mphamvu yamagetsi ndi yapamwamba ndipo ma harmonics ndi ang’onoang’ono, kotero palibe chifukwa choyikira chipangizo chowongolera mphamvu. Izi zitha kupulumutsa ogwiritsa ntchito ndalama zambiri, komanso ndi zida zapamwamba zomwe dipatimenti yopereka magetsi imalimbikitsa mwamphamvu.

3. Pamene ng’anjo yapakatikati yapakati ikugwira ntchito, chowongolera nthawi zonse chimagwira ntchito mokwanira, ndipo mphamvu yotulutsa mpweya wa inverter imasinthidwa ndikuwongolera ma frequency a inverter trigger pulse. Ndipo katundu wapano ndi mafunde a sine, kotero kuti ng’anjo yapakatikati yapakatikati siyiyipitsa kwambiri gululi yamagetsi ndi ma harmonics apamwamba, ndipo mphamvu ndiyokwera kwambiri. Ma inverter ofananira sangathe kukwaniritsa ntchito imodzi kapena ziwiri zokha zosinthira mphamvu, chifukwa kusintha kwamagetsi kwamagetsi ofananirako kumatheka kokha posintha mphamvu yamagetsi a mlatho wokonzanso. Pamene parallel inverter rectifier mlatho umagwira ntchito pang’onopang’ono, mbali ya rectifier conduction ndi yaying’ono kwambiri. M’boma, mphamvu yazidayo idzakhala yotsika kwambiri, ndipo parallel inverter katundu pano ndi mafunde a square, omwe adzaipitsa kwambiri gululi. Ngati mphamvu isinthidwa ndi kusintha kwa inverter kumbuyo kwa kuthamanga kwa ngodya, kusintha kwa mphamvu kumakhala kochepa kwambiri. Chifukwa chake, magetsi ofananirako a inverter sangathe kukwaniritsa ntchito imodzi ndi ziwiri.
