Bayanin hanyoyi na transformer kamar yadda ake bayyana a cikin IEE-Business 60076

Dalilin Daɗi Masu Siffar da Kukaɗa

Takardun Daɗi Masu Siffar: Daga IEC 60076-1, daɗin masu siffar shi ne daɗi mafi yawa (kVA ko MVA) da aka iya tabbatar da shi ta hanyar adadin lalace mai taimaka, wanda ke ƙare cewa an samar da rayukancin gagarumin damar da kuma abubuwan sarrafa tasirin jiki.

Muhimmancin Tsari Mai Yawance Kukaɗa:

• Kasa na lalace mai ba suka rarrabe (P₀) da kuma kasa na lalace mai suka rarrabe (P_k) sun yawanci kukaɗa mai muhimmanci ga tsarin core da windings.

• Tsari na zama-zama (%) na nemi da ɗaukan windings da kafin bayanai; tsarin da suka da tsari mafi yawa za su iya buƙata da kukaɗa masu yawan.

Abubuwan Sarrafa Windings da Tsarin Siyasa

• Y-Type Winding: Ana amfani da shi a karkashin jiki mai yawa, ya fi kyau, da kuma ya taimaka waɗannan bayanai. Ana amfani da shi a cikin takamantukan Dyn11 don sauya tsari na zero-sequence.

• D-Type Winding: Ya fi kyau a karkashin jiki mai ƙasance, da kuma adadin lalace mai yawa. Idan an haɗa da Y-type windings, yana sauya ɗaya ɗaya na zero-sequence current (misali, Yd11 ko Dyn11 don 10/0.4kV distribution transformers).

Abubuwan Sarrafa Gagarumin Damar da Kukaɗa

Abubuwan Sarrafa Gagarumi:

• AN (Gagarumin Damar na Maida): Ana yi amfani da radiators don gagarumin damar, ya fi kyau amma ana iya haɗe da daɗin masu siffar.

• AF (Gagarumin Damar na Jiki): Ana buƙata fans, yana ƙara kukaɗa amma ana taimaka da daɗin masu siffar mai yawa.

Misalai Kukaɗa (daga takamantukan masana):

Tsarin Bayanai da Kukaɗa Mai Yawanci

• Classes na Bayanai:F-class ko H-class materials na bayanai sun taimaka da tsarin siyasa mai ƙarfi saboda ƙarfin damar mai yawa.

• Takamantukan Abubuwan Sarrafa:Impulse withstand voltages (misali, LI75 AC35 a karkashin jiki mai ƙasance da kuma LI170 AC70 a karkashin jiki mai yawa) sun yawanci fagen windings da kafin bayanai.

Hanyoyi da Kukaɗa Mai Yawanci

Tap Changers: A ±2×2.5% tap range ya buƙata da windings na sarrafa jiki, ina iya ƙara kukaɗa mai tsari.

Bayan Kwari

Kukaɗa masu transformer sun nuna daɗin masu siffar, kasa, abubuwan sarrafa gagarumi, da kuma takamantukan bayanai. Tsarin siyasa na musamman suna taimaka da takamantukan IEC 60076-1 da kuma IEC 60076-8, tare da takamantukan parameter (misali, ). Ya kamata a gudanar da models mai yawan ƙarfi kamar "optimal load rate," idan an amfani da su a cikin IEC standards.
