A PV array DC isolator, inozivikanwawo seDC disconnect switch kana DC isolator switch, chinhu chinoshandiswa mu photovoltaic (PV) masisitimu ekupa nzira yekubvisa iyo yakananga ikozvino (DC) simba rinogadzirwa nemagetsi ezuva kubva kune yese system.Icho chinhu chakakosha chekuchengetedza chinobvumira vashandi vekuchengetedza kana vanopindura zvekukurumidzira kuparadzanisa iyo PV array kubva kune inverter uye zvimwe zvikamu zvekugadzirisa kana kugadzirisa matambudziko.
Heano mamwe mapoinzi akakosha nezve PV array DC isolator:
Chinangwa: Chinangwa chikuru chePV array DC isolator ndechekupa nzira yakachengeteka yekubvisa magetsi eDC anogadzirwa nesolar panels kubva kune yese system.Iyo inova nechokwadi chekuti hapana simba reDC riripo padivi rehurongwa panguva yekugadzirisa kana kana paine emergency.
Nzvimbo: PV array DC isolators inowanzoiswa padyo nesolar panels kana panzvimbo iyo iyo DC wiring kubva pamapanera inopinda muchivako kana kamuri yemidziyo.Iyo inobvumira kuwana nyore uye nekukurumidza kubviswa kwePV array.
Zviyero zvemagetsi: PV array DC isolators yakayerwa kubata voltage uye mazinga azvino ePV system.Iwo zviyero zvinofanirwa kuenderana kana kudarika iyo yakanyanya voltage uye ikozvino yePV array kuti ive nechokwadi chekushanda kwakachengeteka uye kwakavimbika.
Manual operation: PV array DC isolators inowanzoitwa nemaoko switch.Anogona kubatidzwa kana kudzimwa nekupuruzira switch kana kutenderedza mubato.Kana iyo isolator iri panzvimbo yekuregwa, inopwanya dunhu reDC uye inoparadzanisa iyo PV array kubva kune yese system.
Chengetedzo kufunga: PV array DC isolator akagadzirwa aine kuchengeteka mupfungwa.Kazhinji vane zvinhu zvakaita sezvibatiso zvinovharika kana zvivhariso kudzivirira kupinda kusina mvumo kana kukanganisa.Zvimwe zvitsaura zvinewo zviratidzo zvinooneka kuratidza chimiro chekuchinja, zvichiratidza kana iyo PV array yakabatana kana kubviswa.
Kutevedzera zviyero: PV array DC isolators inofanirwa kutevedzera zviyero nemirau, senge National Electrical Code (NEC) kana International Electrotechnical Commission (IEC) zviyero, zvichienderana nehutongi.Kuteerera kunovimbisa kuti iyo isolator inosangana nezvinodiwa zvekuchengetedza zvinodiwa.
Zvakakosha kubvunza ane hunyanzvi hwemagetsi kana solar installer paunenge uchisarudza nekuisa PV array DC isolator kuti uve nechokwadi chekuyera, kuiswa, uye kuteedzera macode emagetsi emuno nemirairo.SAKA TINOKUMBIRA KUTI TINZURE NEKUDA KWAKO KWAKAKOSHA: https://www.cncele.com/
