5. Efficiency uye derating factors: mvumo yekurasikirwa kwe inverter, kudzika kunoshandiswa kwekubuda, zera rebhatiri uye tembiricha.

Kana chimwe chezvikoshi izvi chisipo, mhedzisiro yacho inogona kutsausa.

VA, Watts uye Watt-Hours Haana Kufanana

Mazhinji UPS saizi kukanganisa anotanga nekurapa VA, watts uye watt-maawa seanochinjika.

Hukama hwekutanga pakati pe watts neVA ndeiyi:

Watts = VA × Simba Factor

Naizvozvo:

Inodiwa VA = Rodha Watts ÷ Simba Factor

Muenzaniso: kana zvishandiso zvichishandisa 1,800 W uye iyo inoshanda simba chinhu 0.9:

1,800 W ÷ 0.9 = 2,000 VA

Iyo UPS inofanirwa kutsigira ingangoita 1,800 W uye 2,000 VA. Muganho wekuronga uye mvumo yekukura mune ramangwana inofanira kubva yawedzerwa usati wasarudza yekupedzisira modhi.

Nhanho-ne-nhanho UPS Runtime Formula

Nhanho 1: Verenga iyo Nominal Battery Energy

Kune imwe tambo yebhatiri:

Nominal bhatiri simba (Wh) = DC bhazi voltage × bhatiri Ah

Kana tambo dzakafanana dzakabatanidzwa mukufanana:

Nominal bhatiri simba (Wh) = DC bhazi voltage × Ah × nhamba yetambo dzakafanana

Mune akatevedzana tambo, bhatiri voltages anowedzera asi iyo Ah chiyero haidaro. Mune tambo dzakafanana, Ah huwandu hunowedzera nepo tambo yemagetsi inoramba yakafanana.

Danho 2: Shandisa Kubudirira

Iyo inverter uye yemukati UPS zvikamu zvinodya simba. Kuverengera kuronga kunogona kushandisa chinhu chinoshanda senge 0.85 kusvika 0.95, zvichienderana nehurongwa uye mutoro.

Simba mushure mekutendeuka kurasikirwa = Nominal Wh × UPS kunyatsoshanda

Shandisa iyo chaiyo mugadziri data kana iripo.

Nhanho 3: Shandisa Inoshandiswa-Kugona uye Mamiriro ezvinhu

Bhatiri harifanirwe kubatwa sekunge 100% yesimba rayo rezita richagara richisvika pamutoro. Shandisa zvinhu zve:

• shoma inobvumirwa discharge voltage;
• bhatiri chemistry uye chiyero chekubuda;
• zera uye mamiriro ehutano;

• usable-capacity factor: 70%.

Nominal energy:

48 V × 100 Ah = 4,800 Wh

Inofungidzirwa kushandiswa kwesimba:

4,800 Wh × 0.90 × 0.70 = 3,024 Wh

Kuronga nguva yekumhanya:

3,024 Wh ÷ 800 W = maawa 3.78, kana maminitsi angangoita 227

Iyi fungidziro yesimba iri nyore. Chaiyo nguva yekumhanya inogona kuva ipfupi nekuti lead-asidhi simba rinoshanduka nechiyero chekubuda, zera rebhatiri uye cutoff voltage. Mugadziri wenguva yekumhanya anodiwa asati avimbisa 227 maminetsi kumushandisi wekupedzisira.

Yakashanda Muenzaniso 2: Nhatu-Phase Bhizinesi Mutoro

Fungidzira:

• mutoro wakakomba: 10,000 W;
• DC bhatiri bhangi: 384 V, 100 Ah;
• tambo imwe yebhatiri;
• kunyatsoronga: 92%;
• usable-capacity factor: 70%.

Nominal energy:

384 V × 100 Ah = 38,400 Wh

Inofungidzirwa kushandiswa kwesimba:

38,400 Wh × 0.92 × 0.70 = 24,729.6 Wh

Kuronga nguva yekumhanya:

24,729.6 Wh ÷ 10,000 W = maawa 2.47, kana maminitsi angangoita 148

Uyu muenzaniso unoratidza kuti fomula inoshanda sei, kwete dhizaini yepasirese. Huwandu hwebhatiri, DC voltage uye huwandu hwekuchaja hunofanirwa kuenderana neUPS yakasarudzwa. Yakakwira-voltage bhatiri masisitimu inoda nyanzvi yeinjiniya, midziyo yekudzivirira uye nzira dzakachengeteka dzekuisa.
