Momwe Mungawerengere Nthawi Yothamanga ya UPS: Fomula, Zitsanzo ndi Kukula Kwa Battery 

Kodi UPS idzasunga zida zikuyenda mpaka liti pamene magetsi azimitsidwa? Yankho limatengera zambiri kuposa nambala ya VA yosindikizidwa patsamba lakutsogolo. Nthawi yothamanga ya UPS imatsimikiziridwa ndi katundu weniweni wolumikizidwa, mphamvu ya batri, mphamvu ya inverter, mphamvu yotha kutulutsa, mawonekedwe a batri ndi kutentha kwa ntchito.

Yankho lofulumira: Chiyerekezo chokonzekera bwino ndi:

Nthawi yogwiritsira ntchito (maola) ≈ voliyumu ya banki ya banki × ma amp-maola × zingwe zofananira × kuchita bwino × chinthu chogwiritsa ntchito ÷ cholumikizidwa mu watts

Fomulayi ndiyothandiza pakukayika koyambirira, koma si nthawi yotsimikizika yothamanga. Makhalidwe otulutsa lead-acid siwofanana, ndipo makina enieni amakhalanso ndi malire a inverter cutoff, kukalamba kwa batri, kutayika kwa zingwe ndi zotsatira za kutentha. Kusankha komaliza kuyenera kugwiritsa ntchito data yothamanga ya wopanga UPS ndi kuwerengera batire kwachindunji.

Zolowetsa Zisanu Zomwe Mukufunikira

Musanawerengere nthawi yosunga batire ya UPS, sonkhanitsani izi:

1. Katundu wolumikizidwa mu watts: mphamvu yeniyeni yogwiritsidwa ntchito ndi zipangizo zonse zomwe zidzakhalabe panthawi yozimitsa.
2. Mavoti a UPS watt ndi VA: katunduyo ayenera kukhala pansi pa malire onse awiri.
3. Battery-bank DC voltage: voteji ophatikizana a mabatire olumikizidwa mu mndandanda.
4. Kuchuluka kwa batri mu ma amp-hours: mlingo wa Ah wa chingwe chimodzi; zingwe zofananira zimachulukitsa Ah.
5. Kuchita bwino ndi kuchotsera zinthu: zololeza kutayika kwa ma inverter, kuya kwakuya komwe kungagwiritsidwe ntchito, zaka za batri ndi kutentha.

Ngati chimodzi mwazinthu izi chikusowa, zotsatira zake zingakhale zosocheretsa.

VA, Watts ndi Watt-Hours Sizofanana

Zolakwitsa zambiri za UPS zimayamba ndi VA, watts ndi watt-hours ngati zosinthika.

Ubale woyambira pakati pa watts ndi VA ndi:

Watts = VA × Mphamvu Factor

Chifukwa chake:

Zofunikira VA = Katundu Watts ÷ Mphamvu Factor

Chitsanzo: ngati zida zimadya 1,800 W ndipo mphamvu yogwiritsira ntchito ndi 0.9:

1,800 W ÷ 0.9 = 2,000 VA

UPS iyenera kuthandizira osachepera 1,800 W ndi 2,000 VA. Mphepete mwakukonzekera ndi malipiro amtsogolo amtsogolo ayenera kuwonjezeredwa musanasankhe chitsanzo chomaliza.

Tsatanetsatane ndi Gawo UPS Runtime Formula

Khwerero 1: Kuwerengera Mphamvu ya Battery Yodziwika

Kwa chingwe chimodzi cha batri:

Mphamvu ya batire yadzina (Wh) = voliyumu ya basi ya DC × batire Ah

Ngati zingwe zofanana zilumikizidwa molumikizana:

Mphamvu ya batire yadzina (Wh) = voliyumu ya basi ya DC × Ah × kuchuluka kwa zingwe zofananira

Muchingwe chotsatira, ma voltages a batri amawonjezera koma mlingo wa Ah sutero. Mu zingwe zofanana, Ah mphamvu imawonjezera pomwe chingwe chamagetsi chimakhalabe chimodzimodzi.

Gawo 2: Ikani Mwachangu

Ma inverter ndi zida zamkati za UPS zimadya mphamvu. Kuwerengera kokonzekera kungagwiritse ntchito zinthu zogwira mtima monga 0.85 mpaka 0.95, kutengera dongosolo ndi katundu.

Mphamvu pambuyo pa kutembenuka kutayika = Mwadzina Wh × UPS bwino

Gwiritsani ntchito deta yeniyeni ya opanga pamene ilipo.

Khwerero 3: Gwiritsani Ntchito Zomwe Zingatheke ndi Zomwe Zili

Batire sayenera kuchitidwa ngati kuti 100% ya mphamvu yake ya nameplate idzafika nthawi zonse. Ikani zinthu zotsatirazi:

• osachepera ololedwa kutulutsa voteji;
• chemistry ya batri ndi kuchuluka kwa kutulutsa;
• zaka ndi thanzi;
• kutentha kozungulira;
• malo osungirako;
• kutayika kwa chingwe ndi kulumikizana.

Pokonzekera koyambirira, izi zitha kuphatikizidwa kukhala chinthu chogwiritsa ntchito. Mtengo wolondola uyenera kuchokera ku batri ndi zofunikira za kapangidwe ka UPS.

Khwerero 4: Gawani Mphamvu Zogwiritsidwa Ntchito ndi Katundu

Nthawi yothamanga (maola) = Mphamvu ya batri yogwiritsidwa ntchito (Wh) ÷ Katundu (W)

Muchulukitseni ndi 60 kwa mphindi:

Nthawi yothamanga (mphindi) = Nthawi yothamanga (maola) × 60

Ntchito Chitsanzo 1: Small Server Rack

Lingalirani:

• katundu wolumikizidwa: 800 W;
• banki ya batri: 48 V, 100 Ah;

• kukonzekera bwino: 90%;
• Zomwe zimagwiritsidwa ntchito: 70%.

Mphamvu mwadzina:

48 V × 100 Ah = 4,800 Wh

Mphamvu zoyerekeza:

4,800 Wh × 0.90 × 0.70 = 3,024 Wh

Nthawi yokonzekera:

3,024 Wh ÷ 800 W = maola 3.78, kapena pafupifupi mphindi 227

Uku ndi kuyerekeza kwamagetsi kosavuta. Nthawi yeniyeni yothamanga imatha kukhala yayifupi chifukwa kuchuluka kwa asidi wotsogolera kumasintha ndi kuchuluka kwa kutulutsa, zaka za batri ndi mphamvu yamagetsi. Wopanga nthawi yokhotakhota amafunika asanalonjeze mphindi 227 kwa wogwiritsa ntchito.

Ntchito Chitsanzo 2: Katundu Wamagawo Atatu Amalonda

Lingalirani:

• katundu wovuta: 10,000 W;
• banki ya batri ya DC: 384 V, 100 Ah;
• chingwe chimodzi cha batri;
• kukonzekera bwino: 92%;
• Zomwe zimagwiritsidwa ntchito: 70%.

Mphamvu mwadzina:

384 V × 100 Ah = 38,400 Wh

Mphamvu zoyerekeza:

38,400 Wh × 0.92 × 0.70 = 24,729.6 Wh

Nthawi yokonzekera:

24,729.6 Wh ÷ 10,000 W = maola 2.47, kapena pafupifupi mphindi 148

Chitsanzochi chikuwonetsa momwe fomula imagwirira ntchito, osati mawonekedwe achilengedwe chonse. Kuchuluka kwa batri, mphamvu yamagetsi ya DC ndi kuchuluka kwacharging ziyenera kufanana ndi UPS yosankhidwa. Makina a batri okwera kwambiri amafunikira uinjiniya waukadaulo, zida zodzitetezera komanso njira zosungirako zotetezeka.

Chifukwa chiyani Real UPS Runtime Nthawi zambiri Imakhala Yotsika Kuposa Kuwerengera Koyenera
