Wani irin matsakaicin mitar wutar lantarki zai iya biyan bukatun induction narkewa tanderu?

1 Abubuwan buƙatun ikon fitarwa na murhun narkewar shigar da wutar lantarki na tsaka-tsakin mitar thyristor.

Ƙarfin fitarwa na matsakaicin mitar wutar lantarki na thyristor dole ne ya dace da matsakaicin ƙarfin narkewar tanderu, kuma ana iya daidaita ƙarfin fitarwa cikin sauƙi. Wannan shi ne saboda rayuwar crucible na induction narkewa tanderun yawanci game da dubun tanderun kuma ya lalace. Dole ne a sake gina ginin tanderun da aka yi amfani da shi, kuma bayan an gina sabon ginin wutar lantarki, dole ne a yi amfani da tanda mai ƙananan wuta a kai. Yawanci, tanderun yana farawa daga 10-20% na ƙarfin da aka ƙididdigewa, sa’an nan kuma ƙara ƙarfin ta hanyar. 10% a tazara na yau da kullun har zuwa ƙimar ƙarfin wutar lantarki. Bugu da ƙari kuma, a cikin tsarin tanderun, lokacin da cajin ya narke, dole ne a gwada abun da ke cikin cajin. Yayin gwajin, don hana cajin daga narkewa da tafasa da ƙarfi, matsakaicin wutar lantarki dole ne ya rage ƙarfin fitarwa don kiyaye cajin ya yi dumi. Dangane da halin da ake ciki a sama, ana buƙatar cewa za a iya daidaita wutar lantarki ta tsaka-tsakin tsaka-tsakin thyristor daga 10% -100% na ƙimar fitarwa. Tanderun diathermic da ake amfani da su don ƙirƙira ba shi da tsarin yin burodi.

2 Abubuwan buƙatun mitar fitarwa na murhun narkewar shigar da wutar lantarki na tsaka-tsakin mitar thyristor.

Dangantakar da ke tsakanin ingancin wutar lantarki da mitar tanderun narkewa tana da alaƙa. An fara daga ingancin wutar lantarki, ana iya tantance mitar fitarwa na tsaka-tsakin mitar wutar lantarki na thyristor. Misali, muna kiran wannan mita fo. Inductor a haƙiƙa coil ne mai inductive, kuma don rama ƙarfin amsawa na nada, ana haɗa capacitor a layi daya a ƙarshen biyun na coil, wanda ya ƙunshi LC oscillating circuit. Lokacin da fitarwa mita f na thyristor inverter yayi daidai da na halitta oscillation mita fo na induction narkewa narke madauki, sa’an nan ikon factor na madauki daidai da 1. Za a samu matsakaicin iko a cikin induction narkewa tanderu. Ana iya gani daga sama cewa mitar oscillation na dabi’a na madauki yana da alaƙa da ƙimar L da C. Gabaɗaya, ƙimar diyya capacitor C yana daidaitawa, yayin da inductance L ya canza saboda canjin canji. permeability coefficient na tanderun abu. Ƙarfin wutar lantarki μ na ƙarfe mai sanyi yana da girma sosai, don haka inductance L yana da girma, kuma lokacin da zafin jiki na karfe ya fi girma fiye da Curie point, ma’auni mai mahimmanci μ = 1 na karfe, don haka inductance L yana raguwa, don haka madauki narkewar tanderun induction Mitar oscillation na halitta fo zai canza daga ƙasa zuwa babba. Domin sanya murhun murɗawa shigar da wutar lantarki koyaushe ya sami matsakaicin ƙarfi yayin aikin narkewa, wannan yana buƙatar mitar fitarwa f na matsakaicin mitar wutar lantarki na thyristor na iya canzawa tare da canjin fo, kuma koyaushe kiyaye mitar ta atomatik.

3 Sauran buƙatun don samar da wutar lantarki na matsakaicin mitar thyristor.

Wannan saboda lokacin da cajin tanderu ke narkewa, da zarar matsakaicin wutar lantarki ya gaza, crucible zai lalace a lokuta masu tsanani. Sabili da haka, ana buƙatar samar da wutar lantarki na tsaka-tsakin tsaka-tsakin thyristor don yin aiki da dogaro, kuma dole ne ya kasance yana da mahimmancin ƙarfin lantarki mai iyakance kariyar ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun wutar lantarki da kariya na yau da kullun, da yanke ruwa. Kariya, da sauran na’urorin kariya ta atomatik. Bugu da ƙari, ana buƙatar cewa ƙarfin wutar lantarki na tsaka-tsakin tsaka-tsakin thyristor yana da babban nasara na farawa, kuma aikin farawa ya kamata ya dace.
