Kev ceev faj rau kev txhim kho qis - voltage capacitors hauv ib puag ncig sab hauv

Hauv kev tsim kho cov kev siv nyiaj fais fab hluav taws xob hauv chav xa khoom siv hluav taws xob, kev teeb tsa zoo ntawm cov khoom siv kev nyab xeeb ntawm cov khoom siv thiab cov txiaj ntsig ntawm kev them nyiaj. Yog li, dab tsi yog qhov ceev faj thiab cov ntsiab lus tseem ceeb rau kev teeb tsa hauv av {2} Mounted Capacitors hauv chav?

I. Cov kev xav tau yooj yim rau kev teeb tsa ib puag ncig

Sab hauv ib puag ncig rau kev txhim kho qis - voltage capacitors yuav tsum tau nruj me ntsis tswj tau. Lub ambient kub yuav tsum tau tswj hwm nruab nrab ntawm -25 Degree thiab {{{{}}} degree, nrog cov txheeb ze cov av noo tsis zoo tshaj 85% thiab tsis muaj hws. Txhua lub castror yuav tsum tau muab nrog lub tshav kub kub dissipation plhaw ntawm ntau dua lossis sib npaug nrog 100mm, thiab qhov kev ncua deb ntawm cov pawg yuav tsum khaws cia siab tshaj 50 hli. Noj ib tug 400v / 30kvar capacitor ua ib qho piv txwv, lub teeb meem ntawm ib chav yog} kg, thiab lub installation bracket thauj coefficient coj raws li 1.5 zaug ntawm cov npoo kev ruaj ntseg. Nyob rau tib lub sijhawm, kev co cov kev co yuav tsum zam thiab kev sib txuas xoob yuav tsum tau tiv thaiv.

Ii. Hluav Taws Xob Cov Khoom Siv Kev Tshwj Xeeb

Kev teeb hluav taws xob yuav tsum ua raws cov qauv nruj. Tus ntoo khaub lig {{1} ntu ntu ntawm cov xaim yog xaiv ntawm 1.5 zaug tus ntaus nqi tam sim no, thiab tus tooj liab- Al} Al} Aleinate sib txuas nrog cov tshuaj pleev tau sib txuas. Txhua lub catacitor tau nruab nrog fuse nrog lub fuse ua ke, nrog cov ntaus nqi tam sim no tau 1.6 - 2.0 sij hawm cov rated tam sim no ntawm lub capacitor. Lub hauv paus av hlau muaj tus ntoo khaub lig {7} Ntu ntu ntawm ntau dua lossis sib npaug nrog 16 hli, thiab cov av tiv taus tsawg dua lossis sib npaug rau 4ω. Yog tias nws yog nyob rau hauv ib daim phiaj nrog kev sib haum xeeb, ib 7% lossis 14% reactance cov ntsuas ntsuas tus ntsuas ntsuas ntawm kev sib haum xeeb ntawm Harmonics.

III. Kev nqis tes ntawm kev tiv thaiv kev tiv thaiv kev nyab xeeb

During installation, a multi-layer security protection system must be established. The cabinet's protection level should be no less than IP30, and warning signs should be set on the operation surface. The discharge resistance will reduce the residual voltage to below 50V within 5 minutes, and the discharge circuit should be permanently connected. It is recommended to install a temperature monitoring device, which will trigger an alarm if the temperature exceeds 70℃. For large-capacity compensation devices (>300kvar), Siab Tawv Khoom Siv lossis tawg {{}} Cov lus qhia ua pov thawj yuav tsum tau teeb tsa, thiab cov siab nyem kev yuav tsum zam thaj chaw uas tib neeg nyob.

IV. Txoj kev System debugging thiab kuaj

Ua ntej tso rau hauv kev ua haujlwm, txoj kev debugging yuav tsum muaj. Siv 2500v Meohmeter ntsuas cov rwb thaiv tsev tsis kam ntawm cov electrodes. Rau cov cuab yeej hloov tshiab, nws yuav tsum loj dua los yog sib npaug rau 1000mω. Qhov sib txawv ntawm cov nqi tseem ceeb yuav tsum tau nyob hauv tus nqi rated ± 5% rau {}}}}} theem muaj peev xwm yuav tsum tsawg dua lossis sib npaug rau 5%. Tom qab muaj hwj chim rau, saib xyuas peb -}} theem tam sim no tsis txaus ntseeg tam sim no (<10%), temperature rise (with the temperature difference from the environment ≤ 25℃), and noise level (≤ 45dB). After the first operation for 24 hours, re-tighten the electrical connection points.
