Ungayiguqula kanjani i-KW iye ku-KVA

Wake wazibuza ukuthi kungani i-generator yakho eyi-100 KW akwanele? Kungaba yinkinga ye-Power Factor.

I-KW ilinganisa amandla angempela. I-KVA ikhombisa amandla aphelele asetshenzisiwe - kufaka phakathi imfucuza. Azihlali zinjalo.

Ukuqonda umehluko kubalulekile lapho usayizi wokulinganisa okufana nama-generator, ama-transformers kanye nezinhlelo.

Kulokhu okuthunyelwe, uzofunda ukuthi i-KW neKVA kusho ukuthini, kungani bebalulekile, nokuthi ungaguqula kanjani phakathi kwabo.

Uyini umehluko phakathi kwe-KW neKVA?

Amandla wangempela vs amandla abonakalayo

Ake sikuphule:  I-KW  imele  ama-kilowatts , futhi ingamandla  wangempela . Lokhu kuyingxenye kagesi empeleni eyenza umsebenzi owusizo - njengokujikeleza fan noma ukukhanyisa i-bulb.

Ngakolunye uhlangothi,  i-KVA , noma  ama-kilovolt-amperes ,  anamandla asobala . Kubandakanya wonke amandla angempela namandla athile angezekile angenzi msebenzi kepha avele ageleze ngohlelo. Leyongxenye eyengeziwe ibizwa ngokuthi  amandla okuphendula.

Ngakho-ke, cabanga nge-KW njengoba amandla oyisebenzisayo. I-KVA yilokho uhlelo lwakho  oludonsela  kulo mthombo. Bahlobene kodwa abalingani kuzinhlelo eziningi ze-AC.

Kungani le ndaba? Yebo, uma unwebeka i-generator, motor, noma i-transformer, lo mehluko usiza ukugwema ukugcwala ngokweqile nokwehluleka.

Indima ye-Power Factor ekuguqulweni

Nakhu lapho  izinyathelo zamandla (PF)  zingena khona. Kuyisixhumanisi phakathi kwe-KW neKVA.

I-Power Factor  iyinombolo ukusuka  ku-0 kuye ku-1 . Kukutshela ukuthi kungakanani ugesi owenza umsebenzi wangempela. I-PF yokusho  1 ukuthi wonke amandla awusizo. Kepha lokho akuvamile.

Empilweni yangempela, amasistimu amaningi asebenza ngo  -0.8 pf . Ama-motors, amayunithi we-HVAC, namakhompyutha avame ukudala i-PF ngezansi 1 ngoba agcina futhi abuyisele amandla esikhundleni sokuyisebenzisa konke.

Yingakho ke:

Uma uhlelo lwakho ludinga ama-100 kw ku-0.8 pf, empeleni udinga ama-125 kVA ukusekela. Ngakho-ke, isici samandla aphansi esisho i-KVA ephakeme ye-KW efanayo.
kva = kw ÷ pf

Ithebula lokuqhathanisa elisheshayo (kw vs kva)

Nali itafula lokwenza izinto zicace:

ipharamitha	kw (kilowatt)	kVA (kilovolt-ampere)
Uhlobo lwamandla	Amandla angempela (asebenzayo)	Amandla abonakalayo (awonke)
Uhlobo	kw = voltage × manje × pf	kva = voltage × okwamanje
Kubandakanya i-PF?	Yebo	-Nokuba
