Lub luag haujlwm ntawm kev hloov cov khoom siv hluav taws xob hauv kev lag luam hluav taws xob yog dab tsi?
Tam sim no, vim muaj kev ua haujlwm ntawm substation unmanned tswj txoj cai nyob rau hauv kuv lub teb chaws, kev hloov hluav taws xob hloov ua lub luag haujlwm tseem ceeb hauv peb lub teb chaws thaum lub sijhawm ua haujlwm. Hauv cov khoom siv hluav taws xob, DC hloov hluav taws xob siv hluav taws xob yog siv los tiv thaiv relay, cov khoom siv tsis siv neeg, tswj Circuit Court, teeb pom kev zoo thiab suab thiab teeb pom kev zoo. Rau cov nroj tsuag hluav taws xob thiab substations, qhov no yog cov cuab yeej tseem ceeb. Txij li thaum tsis ua hauj lwm ntawm DC fais fab mov yuav ua rau muaj kev sib tsoo txhua lub sijhawm, cov kev xav tau siab tau muab tso rau ntawm qhov kev ntseeg siab thiab kev ruaj ntseg ntawm DC fais fab mov. Cov khoom siv hluav taws xob DC feem ntau siv silicon-tswj rectifiers. Nyob rau hauv xyoo tas los no, ntau lub tuam txhab hluav taws xob DC tau tshaj tawm cov khoom siv hluav taws xob hloov hluav taws xob ntse. Lub tshuab hluav taws xob no muaj ntau yam zoo, xws li kev nyab xeeb, kev cia siab, siab automation, miniaturization thiab lub teeb yuag, kev ua haujlwm siab tag nrho thiab tsis tshua muaj suab nrov, tsim nyog rau kev tsim kho cov kev xav tau ntawm daim phiaj hluav taws xob, thiab nws tsim nyog siv.
Tam sim no, DC fais fab mov siv nyob rau hauv Nyiv lub zog hluav taws xob yog maj mam hloov los ntawm ib txwm theem tswj fais fab mov mus rau ib tug modular high-frequency switching fais fab mov. Lub hauv paus ntsiab lus ntawm kev hloov pauv hloov hluav taws xob ntau zaus: AC fais fab mov yog txuas nrog lub rectifier module. Tom qab lim thiab peb-theem puv-yoj rectification, nws txuas nrog lub siab zaus inverter Circuit Court rau DC fais fab thiab hloov dua siab tshiab. Txuas qhov ncaj qha tam sim no mus rau qhov siab zaus hloov tam sim no, thiab thaum kawg cia qhov siab dhau mus. Tom qab mus dhau lub transformer, rectifier choj thiab lim, cov zis yog ruaj khov DC. Lub high-frequency switching fais fab mov yog tsim los ntawm high-frequency switching charging module, lub hauv paus roj teeb thiab ib lub roj teeb pob, thiab lub charger module thiab lub hauv paus roj teeb muaj built-in txawj ntse microprocessors.
Lub siab zaus hloov hluav taws xob hloov hluav taws xob rectifier module muaj lub microprocessor built-in los txhim kho qib ntawm kev tswj cov cuab yeej, ua kom yooj yim, thiab ceev installation thiab commissioning, muab hais tias DC system yuam kev teeb liab yuav tsum ua kom tiav raws li qhov ua tau, ntxiv rau ncaj qha. tso saib cov zis tam sim no ntawm lub module ntawm lub tswj vaj huam sib luag thiab Ntxiv rau qhov tso zis voltage thiab ntau yam kev khiav hauj lwm, nws tseem tuaj yeem saib xyuas cov chaw taws teeb saib xyuas module los ntawm kev sib txuas lus nrog cov khoom siv hluav taws xob hauv substation lossis automation network ntawm DC hloov kev saib xyuas. qhov system. Nws paub ntau yam haujlwm ntawm lub module thiab plaub qhov chaw taws teeb.
Lub high-frequency switching fais fab mov rectifier module muaj tsis siv neeg tam sim no sib koom ua hauj lwm nyob rau hauv parallel lag luam hom. Nyob rau tib lub sij hawm, nws muaj tshaj-tam sim no, tshaj-voltage, instantaneous short-circuit tiv thaiv, muaj kev ruaj ntseg thiab txhim khu kev qha tiv thaiv xob laim ntsuas, thiab muaj peev xwm tiv taus qhov cuam tshuam ntawm cov zis luv-circuit. Tsis tas li ntawd, ntau yam kev ntsuas tau zoo tau raug coj los ua kom tsis txhob cuam tshuam nrog cov khoom siv hluav taws xob ntau zaus thiab kev sib haum xeeb ntawm AC daim phiaj sab.
