Indlela yokubala i-UPS yeXesha lokuSebenza: Ifomula, imizekelo kunye nobungakanani bebhetri 

Kuya kude kube nini i-UPS igcina izixhobo zisebenza ngexesha lokucima kombane? Impendulo ixhomekeke ngaphezu kwenombolo ye-VA eprintwe kwindawo yolawulo. Ixesha lokuqhuba le-UPS limiselwa ngumthwalo wokwenyani oqhagamshelweyo, amandla ebhetri, ukusebenza kakuhle kwe-inverter, umthamo osetyenziswayo wokukhupha, imeko yebhetri kunye nobushushu bokusebenza.

Impendulo ekhawulezayo: Uqikelelo lwesicwangciso esisebenzayo yile:

Ixesha lokusebenza (iiyure) ≈ Amandla ombane ebhetri-ebhankini × ii-amp-iiyure × iintambo ezinxuseneyo × ukusebenza kakuhle × ubungakanani obusebenzisekayo ÷ umthwalo oqhagamshelwe kwiiwathi

Le fomula iluncedo kubungakanani bokuqala, kodwa ayiloxesha lokuqhuba eliqinisekisiweyo. Ukuziphatha kokukhutshwa kwe-lead-asidi akunamgca, kwaye iinkqubo zokwenyani zinemida yokunqanda i-inverter, ukuguga kwebhetri, ilahleko yekhebula kunye nefuthe lobushushu. Ukhetho lokugqibela kufuneka lusebenzise idatha yexesha lokusebenza yomenzi we-UPS kunye nokubalwa kwebhetri ethile.

Amagalelo amahlanu owadingayo

Phambi kokubala ixesha lokugcinwa kwebhetri ye-UPS, qokelela la maxabiso:

1. Umthwalo oqhagamshelwe kwiiwatts: amandla okwenene asetyenziswe zizo zonke izixhobo eziya kuhlala zivuliwe ngexesha lokucima.
2. UPS watt kunye nokalisho lweVA: umthwalo kufuneka uhlale ngaphantsi kwemida yomibini.
3. Ibhetri-yebhanki yeDC yombane: i-voltage edibeneyo yeebhetri ezixhunywe kuthotho.

Ukuba kukho nawaphi na ala maxabiso alahlekileyo, isiphumo sinokulahlekisa.

I-VA, iiWatts kunye ne-Watt-Hours azifani

Iimpazamo ezininzi ze-UPS zokulinganisa ziqala ngokuphatha i-VA, iiwatts kunye neeyure ze-watt njengokutshintshana.

Ubudlelwane obusisiseko phakathi kwe-watts kunye ne-VA yile:

Watts = VA × Power Factor

Ngoko ke:

I-VA efunekayo = Layisha iiWatts ÷ Factor yamandla

Umzekelo: ukuba isixhobo sisebenzisa i-1,800 W kwaye umbane osebenzayo yi-0.9:

1,800 W ÷ 0.9 = 2,000 VA

I-UPS kufuneka ixhase ubuncinane i-1,800 W kunye ne-2,000 VA. Umda wokucwangcisa kunye nesibonelelo sokukhula kwixesha elizayo kufuneka kongezwe ngaphambi kokukhetha imodeli yokugqibela.

Inyathelo-nge-Inyathelo le-UPS yeNkqubo yokuSebenza

Inyathelo loku-1: Bala amandla ebhetri yeNominal

Ngomtya webhetri omnye:

Amandla ebhetri yegama (Wh) = amandla ombane ebhasi yeDC × ibhetri Ah

Ukuba imitya efanayo idityaniswe ngaxeshanye:

Amandla ebhetri yegama (Wh) = amandla ombane ebhasi yeDC × Ah × inani leentambo ezihambelanayo

Kuluhlu lweentambo, iivolthi zebhetri zongeza kodwa ukulinganisa kwe-Ah akwenzi. Kwimitya ehambelanayo, umthamo we-Ah wongeza ngelixa i-voltage yomtya ihlala ifana.

Inyathelo lesi-2: Sebenzisa ngokuSebenzayo

I-inverter kunye namacandelo e-UPS angaphakathi asebenzisa amandla. Ubalo lokucwangcisa lunokusebenzisa into esebenzayo efana ne-0.85 ukuya kwi-0.95, kuxhomekeke kwisistim kunye nomthwalo.

Amandla emva kwelahleko yokuguqulwa = I-Nominal Wh × ukusebenza kakuhle kwe-UPS

Sebenzisa eyona datha yomenzi xa ikhona.

Inyathelo lesi-3: Faka i-Sable-Sable-Capacity and Condition Factors

Ibhetri akufanele iphathwe ngokungathi i-100% yamandla e-nameplate yayo iya kuhlala ifika kumthwalo. Sebenzisa izinto zoku:

• intambo enye yebhetri;
• impumelelo yokucwangcisa: 92%;
• ubungakanani obusebenzisekayo: 70%.

Amandla aqhelekileyo:

384 V × 100 Ah = 38,400 Wh

Uqikelelo lwamandla asebenzisekayo:

38,400 Wh × 0.92 × 0.70 = 24,729.6 Wh

Ukucwangcisa ixesha lokusebenza:

24,729.6 Wh ÷ 10,000 W = 2.47 iiyure, okanye malunga nemizuzu eyi-148

Lo mzekelo ubonisa indlela esebenza ngayo ifomula, hayi uyilo lwendalo yonke. Ubungakanani bebhetri, amandla ombane eDC kunye nomthamo wokutshaja kufuneka uhambelane ne-UPS ekhethiweyo.
