Kev ua haujlwm tsis zoo ntawm hnub ci inverter

1. Kev khiav hauj lwm ib puag ncig thiab ib txwm ua haujlwm ntawm lub inverter: qhov siab yuav tsum tsis pub tshaj 1000m, thiab huab cua kub yuav tsum yog 0 ~ ntxiv rau 40 degree.

2. DC input fais fab mov tej yam kev mob, input DC voltage fluctuation ntau yam: ± 15 feem pua ​​ntawm cov rated voltage ntawm lub roj teeb cia.

3. Qhov ntsuas qhov tso zis hluav taws xob, nyob rau hauv qhov tso cai hloov pauv ntau ntawm cov lus qhia DC voltage, sawv cev rau qhov ntsuas hluav taws xob uas lub inverter yuav tsum muaj peev xwm tso tawm. Qhov tseeb stability ntawm qhov ntsuas tso zis voltage feem ntau teev raws li hauv qab no:

(1) Thaum lub sijhawm ua haujlwm tsis tu ncua, qhov hloov pauv qhov voltage yuav tsum raug txwv, piv txwv li, nws qhov sib txawv yuav tsum tsis pub tshaj ± 3 feem pua ​​lossis ± 5 feem pua ​​​​ntawm cov nqi ntsuas.

(2) Nyob rau hauv qhov kev hloov pauv ntawm kev hloov pauv tam sim ntawd lossis lwm yam cuam tshuam, qhov tso zis hluav taws xob sib txawv yuav tsum tsis pub tshaj ± 8 feem pua ​​lossis ± 10 feem pua ​​​​ntawm cov nqi ntsuas.

4. Rated tso zis zaus: qhov zaus ntawm inverter tso zis AC voltage yuav tsum yog tus nqi ruaj khov, feem ntau 50Hz fais fab zaus. Raws li kev ua haujlwm ib txwm muaj, qhov sib txawv yuav tsum nyob hauv ± 1 feem pua.

5. Rated tso zis tam sim no (los yog rated tso zis muaj peev xwm) yog hais txog cov rated tso zis tam sim no ntawm lub inverter nyob rau hauv lub teev load hwj chim yam ntau yam. Qee cov khoom lag luam inverter muab cov peev txheej tso tawm, uas tau qhia hauv VA lossis kVA. Lub peev xwm ntsuas ntawm inverter yog cov khoom lag luam ntawm cov zis tawm hluav taws xob thiab ntsuas cov zis tam sim no thaum cov zis hluav taws xob yog 1 (piv txwv li cov khoom siv dawb huv).

6. Rated tso zis efficiency: qhov ua tau zoo ntawm inverter yog qhov piv ntawm cov zis hluav taws xob rau cov khoom siv hluav taws xob raws li kev ua haujlwm tau teev tseg, qhia hauv feem pua. Qhov ua tau zoo ntawm inverter ntawm cov zis muaj peev xwm yog tag nrho cov khoom ua haujlwm, thiab qhov ua tau zoo ntawm 10 feem pua ​​​​ntawm cov zis muaj peev xwm yog qhov ua haujlwm qis.

7. Qhov siab tshaj plaws harmonic cov ntsiab lus ntawm inverter, lub siab tshaj plaws harmonic cov ntsiab lus ntawm cov zis voltage ntawm sine yoj inverter nyob rau hauv resistive load yuav tsum tsawg tshaj li los yog sib npaug rau 10 feem pua.

8. Lub peev xwm dhau ntawm lub inverter: lub peev xwm ntawm lub inverter tso zis ntau tshaj qhov ntsuas tam sim no hauv lub sijhawm luv luv raws li cov xwm txheej. Lub peev xwm overload ntawm lub inverter yuav tsum ua tau raws li qee qhov yuav tsum tau ua raws li qhov teev tseg ntawm lub zog load.
