Makala na Fasaha don Samun Kwayoyin Tashin Gwamnati na Dandamawa don Samun Kwayoyin Samun Kwayoyin

Samun kammala ta yadda mafi kyau transformer Fiye don dukkiai na sana’a shi ne mafi mahimmanci don amfani da saurin kariya mai tsayi, kula da kariya mai yawa, kuma ba da imkanin rarraba a duniya na gaba. Bayanin baya zai nuna matsaloli na samun kammala na transformer a cikin dukkiai na sana’a.

Matsala 1: Samun dukkiai na kariya

Rubuta dukkiai na kariya wanda transformer ya sauke su, kuma rubuta bayanan kariya don hakan kowanne:

Kammala ta fuskantar (wurin kammala: kW, kVA, HP)

Jami'a Litar

Shirin kariya (shirin daya/shirin uku)

Kariya na amfani (rubuta idan aka sani)

Matsala 2: Gyara dukkiai na kariya zuwa kVA

Don saboda kammala ta fuskantar na transformer ta kammala a kVA, dukkiai na kariya dole ne su gyare su zuwa wannan wuri ta amfani da wadannan formulas:

Kudin kwayoyin talaka: kVA = √3 × V × A / 1000

Kudin kwayoyin talaka ta yanki: kVA = V × A / 1000

Idan kudin amfani da kudin tashin talaka suka fama: kVA = kW / PF

Tsarin 3: Yi hisabon kudin amfani a yanzu ta hanyar amfani da kudin tashin talaka da kudin tsinkanin kwayoyin talaka

Kwayoyin talaka na kasuwanci ba su dambe a cikin kudin amfani mai sauwi ko cikin kudin amfani ta yanki; don haka, kudin talaka biyu suna amfani wajen rarraba kudin da aka hisabta:

Kudin tashin talaka: Ya rarraba kudin amfani mai sauwi na kwayoyin talaka

Kudin tsinkanin kwayoyin talaka (kudin farko): Ya bayyana cewa kwayoyin talaka biyu ko karin ba su ci gaba da kudin amfani ko su ci gaba da kudin amfani ta yanki a lokaci daya

Misali na hisab: Kudin amfani ta yanki shine 1000 kVA; kudin tashin talaka shine 0.8; kudin amfani a yanzu = 1000 × 0.8 = 800 kVA

Tsawo 4: Zai ƙara ƙarfi na amanani

Don gane cikin sauyin tekniki na masa, kaddamarwa na ƙarfi, da yin ƙarfi na yanki, ƙarfi na amanani na 10% –25% an sanya don bincika yin ƙarfi na transformer.

Yi amfani da misalali: Ƙarfi da ke bukata don zabi = 800 × 1.2 = 960 kVA

Tsawo 5: Yi kwatanta da ƙarfin da ke aminci

Kwatanta sona da ƙarfin da ke aminci a sararin ƙarfi na yankin kudande na kudande da za a zabi ƙarfin da ke cikin wani daga cikin ƙarfin da ke aminci wacce suka fi kuma sona. Ƙarfin da ke aminci: 30, 50, 63, 80, 100, 315, 500, 630, 800, 1000, da 1250 kVA. Ya zama tsawo na gaba, transformer na 1000 kVA ta zabi.

Tsawo 6: Tabbata ku ƙarfin da ke cikin jihirin

Tabbata ku ƙarfin da ke cikin biyu na transformer don tabbata ku cewa yana da shugaban kudande:

Ƙarfin na farko ya zama shugaban kudande na gida.

Tashin kudurrin da farko ya zama da kudurrin da aka shigar da abin ƙirƙirin.

Tsakarar 7: Duba ƙayyadaddun halin ayyukan da suka zuwa

Wayar yin sanyi: Abubuwan da suka yi a cikin gida suna da kyau don amfani da su, amma abubuwan da suka yi a waje na gida suna da kyau don amfani da su.

Kudurrin da ke baiwa: Yi amfani da kudurrin da ke baiwa don hana kudurrin da ke baiwa a cikin jihun da ke bayar da kudurrin.

Kudurrin ayyukan: Za a zaɓa abubuwan da suka yi a cikin gida don hana kudurrin da ke bayar da kudurrin a cikin jihun.

Shirin kasuwa: Tabbata kuwa da kudurrin da ke cikin gida, rufin ruwa, sarrafa, da sauran halin ayyukan.

Kammalawa

Zabinta na alakar masifa yana ƙarƙashin yin amfani da safe, kuma yin amfani da energy efficiency, kuma yin amfani da operational stability na power distribution system. Yadda muke lissafi total equipment load ta hanyar daidai, kuma yadda muke zaɓa electrical coefficients ta hanyar daidai, kuma yadda muke bari capacity expansion margins zai iya tabbatar da cewa system ya dace da current production power needs, kuma yana iya tabbatar da future capacity upgrades. A wasu lokaci, yadda muke tabbatar da voltage, operating conditions, kuma equipment parameters zai iya tabbatar da long-term, stable operation na transformer.
