HD 11 N Riam Hloov sawv cev rau qhov tseem ceeb hauv cov tshuab hluav taws xob photovoltaic (PV) niaj hnub, tsim tshwj xeeb rau kev ua haujlwm nyab xeeb thiab txhim khu kev qha hauv kev siv hluav taws xob tauj dua tshiab. Raws li ib tug tshwj xeeb disconnection ntaus ntawv, no riam hloov ua kom muaj kev ruaj ntseg muaj peev xwm nyob rau hauv kev sib cais thaum ua raws li nruj me ntsis kev ua hauj lwm yuav tsum tau rau DC thiab AC distributions nyob rau hauv lub hnub ci zog installation. Nws engineering tsom rau kev ua haujlwm ntev thiab kev nyab xeeb, ua rau nws haum rau ntau yam kev lag luam thiab kev lag luam PV teeb tsa.

MCB Isolator Hloov, tshwj xeeb tshaj yog BYG1-125 series, yog cov ntsiab lus tseem ceeb ntawm cov tshuab hluav taws xob niaj hnub. Tsim los muab kev sib cais ntawm kev nyab xeeb thiab meej meej, cov cuab yeej sib xyaw ua ke kev tiv thaiv ntawm lub tshuab hluav taws xob me me (MCB) nrog lub peev xwm huv si ntawm kev sib cais. Raws li lub ntsiab lus tseem ceeb ntawm kev tswj hwm, nws muaj peev xwm txiav tawm tag nrho cov hluav taws xob mus rau qis qis thaum lub sij hawm tu, kho lossis kaw thaum muaj xwm txheej ceev, yog li ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom siv. Nws txoj kev tsim kho rugged thiab nruj cov qauv hluav taws xob ua rau nws yog ib qho tseem ceeb hauv kev lag luam thiab kev lag luam.

BYW1 series sawv cev rau kev nce qib loj hauv kev tiv thaiv hluav taws xob thev naus laus zis. Tsim los rau AC 50Hz daim phiaj, qhov ntse ntse universal cua Circuit Court breaker (ACB) yog ntsuas txog 690V thiab muaj peev xwm tuav tau txog li 6300A. Raws li lub hauv paus ntawm kev nyab xeeb fais fab kev faib tawm, nws ntseeg tau los tiv thaiv kev tsim kho tseem ceeb hauv cov nroj tsuag kev lag luam, cov chaw lag luam, thiab cov chaw loj los ntawm kev puas tsuaj hluav taws xob.

Cov khoom siv hluav taws xob niaj hnub xav tau kev daws teeb meem kev nyab xeeb, thiab BY02L-63 series muab kev tiv thaiv tseem ceeb. Qhov Residual Current Circuit Breaker (RCBO) ua ke nrog overcurrent, luv-circuit, thiab lub ntiaj teb to tiv thaiv nyob rau hauv ib tug compact ntaus ntawv. Rated rau 3kA tawg muaj peev xwm, nws tiv thaiv vaj tse, kev lag luam, thiab kev lag luam tshuab tiv thaiv hluav taws xob tiv thaiv hluav taws xob thiab hluav taws kub nyhiab tshwm sim los ntawm rwb thaiv tsev faults. Nrog rau rhiab heev rau qhov txaus ntshai qhov seem tam sim no (feem ntau 30mA), nws tam sim ntawd disconnects circuits thaum muaj kev cuam tshuam rau lub neej tsis txaus, muab kev tiv thaiv cov neeg ua haujlwm tseem ceeb.

BY08DC 1 + 2-12.5 series sawv cev rau kev nce qib tseem ceeb hauv kev tiv thaiv photovoltaic. Qhov tshwj xeeb Dc Surge Protective Device (SPD) no muab qhov tseem ceeb T1 + T2 surge tiv thaiv tshwj xeeb tsim rau lub hnub ci sib txuas lub thawv thiab cov inverter. Siv high-zog hlau oxide varistor (MOV) thev naus laus zis, nws muab kev tiv thaiv zoo tiv thaiv xob laim (10/350μs) thiab hloov pauv hloov pauv (8/20μs). Nrog kev tso tawm muaj peev xwm ntawm 20kA txog 40kA ib tus ncej, SPD no ua kom cov khoom siv DC tseem ceeb tseem tiv thaiv los ntawm kev puas tsuaj hluav taws xob thoob plaws hauv nws lub neej ua haujlwm.

BY04L-63 series sawv cev rau kev nce qib tseem ceeb hauv kev nyab xeeb hluav taws xob, sib xyaw ua haujlwm tiv thaiv tseem ceeb rau hauv ib qho khoom siv. Qhov Residual Current Circuit Breaker (RCBO) no muab kev tiv thaiv zoo tiv thaiv peb qhov teeb meem loj: overcurrent, short-circuit, thiab txaus ntshai residual tam sim no (lub ntiaj teb to). Tsim los rau kev ntseeg siab, nws muaj txiaj ntsig zoo tiv thaiv ob tus neeg ua haujlwm los ntawm hluav taws xob poob siab thiab kev teeb tsa los ntawm hluav taws kub txaus ntshai los ntawm kev cuam tshuam los ntawm kev rwb thaiv tsev los yog ntau dhau tam sim no, ua rau nws tseem ceeb rau cov tshuab hluav taws xob niaj hnub no.
