Zoo sib xws thiab qhov sib txawv ntawm Fuse, Circuit Breaker Thiab Disconnector

Kev lag luam Photovoltaic (PV) tab tom muaj kev loj hlob sai raws li kev sib txawv ntawm Carbon-Neutrality-oriented txoj kev loj hlob, uas txawm li cas los xij tau ua rau muaj teeb meem ntau ntxiv nyob ib puag ncig kev nyab xeeb ntawm cov nroj tsuag hluav taws xob vim tias cov khoom siv hluav taws xob ntau dua tau siv dav. PV system tsim tau nce mus rau qhov nyuaj raws li cov ntawv thov tshiab thiab cov xwm txheej siv tau pom. Yuav ua li cas xa cov qauv kev tiv thaiv ntawm DC sab ib txwm muaj kev txhawj xeeb thiab kev tsis sib haum xeeb hauv kev lag luam. Hauv paus, kev nkag siab yuam kev ntawm fuse, Circuit Court breaker thiab disconnector uas feem ntau siv los tiv thaiv PV system yog lub hauv paus.

Fuse, Circuit Court breaker thiab disconnector, vim tias lawv cov haujlwm zoo sib xws (kev sib cais, kev tiv thaiv luv luv thiab lwm yam), yog qhov ua rau muaj kev tsis sib haum xeeb thiab kev nkag siab tsis zoo hauv kev lag luam. Txawm li cas los xij, qhov tseeb, lawv yog cov khoom siv sib txawv kiag li, vim tias lawv muaj qhov sib txawv ntawm cov hauv paus ntsiab lus ntawm kev tiv thaiv, tus qauv yuav tsum tau muaj, qhov xwm txheej ntawm daim ntawv thov thiab kev tiv thaiv! Raws li kev tsim kom muaj kev tiv thaiv kev faib tawm, nws yuav tsum nkag siab tag nrho cov cai ntawm kev tsim khoom raws li cov xwm txheej ntawm daim ntawv thov, kom cov cuab yeej siv tau tsim nyog raws li lawv tus kheej cov yam ntxwv los muab cov ntawv thov kom raug rau lawv txoj haujlwm, yog li txhim kho kev nyab xeeb thiab kev ua haujlwm. kev ntseeg ntawm qhov chaw nres tsheb.

Fuse: xa mus rau tus tiv thaiv tam sim no uas muaj cov khoom siv fuse thiab cartridge. Lub fuse lub caij yuav raug tshuab tawm los ntawm cov cua sov uas tsim los ntawm nws tus kheej thaum tam sim no outnumbers txwv rau ib lub sij hawm, thiab nyob rau hauv cov ntaub ntawv no Circuit Court yuav raug txiav tawm kom lub hom phiaj ntawm kev tiv thaiv yuav ua tau tiav.
Circuit Court breaker: xa mus rau lub tshuab hloov khoom siv uas muaj peev xwm hloov tau / tawm thiab nqa tam sim no thiab muaj kev sib cuag, lub kaw lus arc quenching, tus actuator thiab chav mus ncig. Nws yog siv los txiav tawm ib lub voj voog uas tsis ua haujlwm kom ua tiav lub hom phiaj ntawm kev tiv thaiv. Nyob rau hauv cov ntaub ntawv ntawm ib tug luv luv Circuit Court, lub counter-force lub caij nplooj ntoos hlav yuav kov yeej los ntawm ib tug magnetic teb uas tsim los ntawm ib tug ntau dua tam sim no, nyob rau hauv cov ntaub ntawv no tus actuator yuav tsum tau tsav los ntawm lub mus txawv tebchaws unit los hloov tam sim ntawd. Nyob rau hauv cov ntaub ntawv over-load, bimetallic strips yuav deformed mus rau ib qho twg ntawm qhov kub thiab txias vim yog nce tam sim no, ua rau lub actuator hloov tawm. Qhov siab dua qhov tam sim no, lub sijhawm luv rau qhov kev tiv thaiv no yuav yog.
Disconnector: los ua haujlwm feem ntau yog ib qho kev sib cais uas tuaj yeem tsim qhov pom tseeb ntawm kev tawg ntawm cov khoom siv hluav taws xob tau hloov kho thiab lub zog hluav taws xob, kom lav kev nyab xeeb ntawm kev kho dua. Yav dhau los, manually-ua haujlwm disconnector yog muab rau ntawm DC sab ntawm txoj hlua inverter. Nrog rau kev txhim kho ntse ntawm PV chaw nres tsheb, manually-ua haujlwm disconnector yog hloov los ntawm lub cev muaj zog ua haujlwm disconnector.
