Ka’idar injin wutar lantarki: buƙatun don da’irar faɗakarwa rectifier

1. Don mita da lokacin bugun bugun jini, muna amfani da nau’in gada mai cikakken iko mai cikakken iko, wanda ke raba abubuwan thyristor guda shida. Don haka, ana buƙatar da’irar faɗakarwa don samar da siginonin faɗakarwa na lokaci-lokaci guda shida (Vg, Vg2, Vg3, Vg4, Vg5, V g6) Kuma alaƙar lokaci na bugun bugun faɗar shida shine 60° daban-daban a jere.

2. Pulse nisa da jagorar baki: a cikin nazarin ka’idar aiki na nau’in gada mai nau’in nau’in gada mai cikakken iko, an ambaci cewa gada mai cikakken iko dole ne ya kunna thyristors biyu a kowane lokaci, wanda ke buƙatar. kowane sake zagayowar (360°) A ciki, dole ne a kasance kuma bugun jini guda biyu ne kawai ke wanzu a kowane lokaci. Saboda haka nisa daga kowane bugun jini ya kamata ya zama mafi girma T/60=60°, kuma nisa bugun bugun jini bai kamata ya kasance mai fadi da yawa ba. Gabaɗaya, ana fatan ya zama ƙasa da T/3/120°. Don kunnawa daidai, ana buƙatar bugun bugun bugun jini ya sami isasshe babban jagora, amma saboda mitar bugun bugun jini a cikin tsarin gyara guda ɗaya yayi ƙasa (50Hz) kuma faɗin bugun bugun yana da girma (fiye da T/6), idan Abubuwan da ke cikin thyristor ba a haɗa su a cikin jerin ba, Abubuwan da ake buƙata don jagorancin jagorar bugun jini ba shi da yawa, idan dai zai iya zama ƙasa da 0.3ms.

3. Ƙarfin bugun jini, don kunna thyristor a ƙarƙashin amfani da bugun jini, ana buƙatar bugun bugun jini don samun wani iko. Matsakaicin wutar lantarki mai faɗakarwa da matsakaicin ƙarfin halin yanzu na lantarki mai sarrafawa da ake buƙata ta thyristors na iyakoki daban-daban sun bambanta.

Misali, matsakaicin matsakaicin ƙarfin wutar lantarki na KP200A shine 4V, matsakaicin matsakaicin ƙarfin halin yanzu shine 200mA, matsakaicin ƙarfin ƙarfin ƙarfin gaba na sandar sarrafawa shine 10V, matsakaicin ƙyalli da aka yarda da sandar iko shine 2A.

1. Canjin lokaci, don ba da damar ƙarfin lantarki na rectifier don saduwa da buƙatun siginar “iyakar yanzu”, “iyakar ƙarfin lantarki”, “overcurrent”, “overvoltage”, da dai sauransu, ana buƙatar lokacin bugun bugun rectifier wanda ya haifar da shi. bugun bugun jini na iya zama tsakanin “0° ~ 150°”A cikin iyakar canjin.
