Zog Cia PCS
Lub tshuab hluav taws xob cia yog ib qho tseem ceeb ntawm cov tshuab hluav taws xob txuas dua tshiab niaj hnub. Lawv tau siv dav vim tias lawv txo cov pov tseg hluav taws xob zoo thiab txhim kho tag nrho cov txiaj ntsig ntawm lub zog hluav taws xob. Vim muaj kev sib cuam tshuam ntawm cov roj teeb thiab daim phiaj fais fab, cov converters yuav tsum tau ua AC-DC hloov dua siab tshiab thiab pab kom bidirectional zog txaus. Tsis tas li ntawd, cov hloov pauv ua lub luag haujlwm tseem ceeb hauv lub zog khaws cia los ntawm kev tswj hwm lub zog los ntawm kev tswj qhov loj thiab kev taw qhia ntawm tam sim no, ua rau lub ncov shaving thiab hav filling los txhim kho kev siv hluav taws xob zoo, nrog rau kev tiv thaiv overload kom muaj kev nyab xeeb ntawm lub cev.
Nruab nrab ntawm lub rectifier circuit thiab converter circuit, aDC-LINK capacitoryog xav tau rau kev txhawb nqa tam sim no thiab kev lim dej. Nws lub luag haujlwm tseem ceeb yog nqus cov mem tes siab tam sim no ntawm DC-LINK tsheb npav, tiv thaiv cov mem tes hluav taws xob siab los ntawm kev tsim tawm ntawm impedance ntawm DC-LINK. Qhov no tseem tiv thaiv qhov kawg ntawm qhov kev cuam tshuam ntawm overvoltage.
YMIN capacitors muaj cov yam ntxwv hauv qab no hauv lub converter teb
01. Muaj peev xwm
DC-Link capacitor khaws cov hluav taws xob hluav taws xob, ua kom nws muab lub zog txuas ntxiv mus rau lub tshuab hloov pauv thaum lub sijhawm muaj qhov cuam tshuam loj ntawm kab hluav taws xob lossis hluav taws xob tawm, ua kom lub cev ua haujlwm ib txwm muaj. Tsis tas li ntawd, thaum lub converter system xav tau ntau lub zog, DC-Link capacitor tuaj yeem tso tawm lub zog sai sai kom tau raws li qhov xav tau ntawm lub sijhawm. Nyob rau hauv inductive loads xws li motors, lub capacitor kuj muab reactive zog them, stabilizes voltage, thiab txhim kho lub cev muaj zog kev ua tau zoo. Qhov no plays lub luag haujlwm tseem ceeb hauv kev txhim kho qhov system efficiency thiab stability.
02. Ultra-High Voltage Resistance
YMIN capacitors, nrog rau lawv cov ultra-high voltage kuj, kuj tuaj yeem ua cov khoom tiv thaiv. Thaum lub sijhawm ua haujlwm converter, lawv tiv thaiv cov khoom siv hluav taws xob tsis zoo los ntawm kev puas tsuaj los ntawm qhov hluav taws xob hluav taws xob. Qhov no ua rau lub zog cia converters los muab kev ruaj ntseg voltage thiab zaus kev txhawb nqa rau daim phiaj hluav taws xob, kom ntseeg tau tias kev ua haujlwm txhim khu kev qha ntawm lub cev.
03. High Current Surge Resistance
YMIN capacitors zoo nqus cov mem tes siab tam sim no tsim los ntawm lub converter ntawm DC-Txuas kawg, ua kom cov zis hluav taws xob muaj zog los ntawm kev tswj tam sim no. Qhov no ua kom lub converter ua tau raws li qhov xav tau ntawm ntau yam xwm txheej thiab muab cov khoom siv AC zoo. Thaum lub sij hawm pib cov txheej txheem ntawm cov converters, YMIN capacitors tsim ib feem ntawm lub charging Circuit Court, pab tiv thaiv kev cuam tshuam ntau dhau ntawm cov khoom siv hluav taws xob thiab kev thauj khoom.
04. Lub Neej Ntev
Ymin capacitors, tsim los ntawm cov txheej txheem qauv qauv thiab raug ua kom nruj ua ntej kev sib tw, feature high density thiab kev nce tam sim no tsis kam. Cov kev ua tau zoo no ua rau cov hloov pauv hauv lub zog khaws cia kom ua haujlwm ruaj khov nyob rau lub sijhawm ntev, txo qhov ua tsis tiav thiab cov nqi kho.
