Isolator switch ndeye yakakwira-voltage switchgear, inonyanya kushandiswa mumaseketi akakwira-voltage.Iyo switchgear isina arc yekudzima mudziyo, inonyanya kushandiswa kudzima dunhu pasina mutoro wazvino, kupatsanura simba remagetsi, uye kuve nenzvimbo yekudzima iri pachena munzvimbo yakavhurika kuti ive nechokwadi chekutarisa kwakachengeteka uye kugadziriswa kwezvimwe zvigadzirwa zvemagetsi.Iyo inogona kutendeseka kupfuudza yakajairika mutoro ikozvino uye pfupi-yedunhu kukanganisa ikozvino munzvimbo yakavharwa.Nekuti haina yakakosha arc yekudzima mudziyo, haigone kudzima mutoro wazvino uye pfupi-yedunhu ikozvino.Nokudaro, kushandura kwekuzviparadzanisa kunogona kungoshandiswa chete kana dunhu rave rakabviswa nemutambo wedunhu.Izvo zvinorambidzwa zvachose kushanda nemutoro kuti udzivise midziyo yakakomba uye tsaona dzemunhu.Magetsi emagetsi chete, zvinosunga mheni, hapana-mutoro matransformer ane excitation yazvino isingasviki 2A, uye hapana-mutoro maseketi ane ikozvino asingasviki 5A anogona kushandiswa zvakananga nekuzviparadzanisa nevamwe.Mumagetsi emagetsi maapplication, macircuit breakers uye ekuzviparadzanisa nevamwe anonyanya kushandiswa mukubatana, uye iyocircuit breakersanoshandiswa kushandura uye kucheka mutoro (kukanganisa) ikozvino, uye iyo isolator switch inoumba iri pachena yekubvisa poindi.
Thesolar panel dc isolator switchchinhu chekudzivirira chemagetsi chinogona kuzvibvisa pachako kubva kumamodules mu solar photovoltaic system.Mune photovoltaic application, PV DC isolators inoshandiswa pamaoko kubvisa solar panel kugadzirisa, kuisirwa kana kugadzirisa.Mukuisa, kugadzirisa kwechinyakare uye mamiriro ekukurumidzira, iyo pani inoda kuve yakaparadzaniswa kubva kudivi re AC, saka inoshandisirwa nemaoko switch yekuzviparadzanisa inoiswa pakati pepaneru neinopinza inverter.Iyi mhando yekuchinja inonzi PV DC isolator switch nekuti inopa DC yekuzviparadzanisa pakati peiyo photovoltaic panel uye yese system.Iyi ndiyo yakakosha kuchengetedza switch, inosungirwa mune yega yega photovoltaic simba rekugadzira system zvinoenderana neIEC 60364-7-712.Solar panel dc isolator switch ndechimwe chezvinhu zvakakosha zve photovoltaic system kuchengetedza.Kuvimbika kwayo uye kugadzikana kwakabatana neyakagadzika simba rekugadzira uye purofiti yeiyo photovoltaic system, pamwe nekuchengetedza uye kwakavimbika kushanda kweiyo photovoltaic system.Nekuwedzera kwekuisa photovoltaic, kugadzirwa kwemagetsi kwakakwezva kutarisisa kwakawanda.Zvisinei, vatengesi vemagetsi vari kuwedzera kunetseka pamusoro pekuchengetedza nyaya, izvo zvinowanzoitika mumagetsi e photovoltaic mumakore achangopfuura.
Nyika dzeEurope dzakaita seGermany neNetherlands dzinoda vanogadzira inverter kuti vagadzirise yakavakirwa-mukati PV DC isolator switch, nepo nyika dzakaita seUnited Kingdom, India, neAustralia dzichida kuti photovoltaic masisitimu anofanirwa kuisa ekunze PV DC isolator switch.Nekujekeswa kweChina's photovoltaic policy, nhamba ye photovoltaic installs yakawedzera gore negore, kunyanya kune akagoverwa photovoltaic systems, uye matenga edenga akawedzera kufarirwa.
Nekudaro, iyo inonzi photovoltaic DC isolator switch pamusika ndeyeAC isolator switchkana yakagadziridzwa wiring vhezheni, kwete DC inoparadzanisa switch ine chaiyo arc yekudzima uye yakakwirira-simba rakacheka-kubvisa mabasa.Aya maAc isolator switch arikushaikwa zvakanyanya mukudzima arc uye simba rekuzviparadzanisa kubva pamutoro, izvo zvinogona kutungamira mukupisa zvakanyanya, kuvuza uye sparks, uye kunyange kupisa chiteshi chemagetsi chephotovoltaic.
Naizvozvo, zvakakosha kwazvo kusarudza inokwanisa solar panel dc isolator switch.BS 7671 inotaura kuti nzira yekuzviparadzanisa inofanira kupihwa kudivi reDC rekuisa photovoltaic, iyo inogona kupihwa neinoparadzanisa switch yakarongedzwa mu EN 60947-3.
Saka, ungasarudza sei yakakodzera PV DC yekuparadzanisa switch yeiyo photovoltaic system?
Iyo yakatemerwa kushanda voltage yeDC yekuparadzanisa switch inofanirwa kuenzana kana yakakura kupfuura zvinodiwa nehurongwa.Zvakajairika zvinosangana UL508i 600V, IEC60947-3 1000V uye 1500V.Kazhinji system voltage yakabatana kune imwe-phase inverter yakakwira se600V, uye matatu-chikamu tambo inverter kana centralized inverter yakakwira se1000V kana 1500V.
2 Mboro – Tambo imwe chete, 4 Danga – Tambo mbiri.
Kune yakavakirwa-mukati DC isolator switch, nhamba yeMPPT ye inverter inosarudza danda reDC isolator.Yakajairwa tambo inverters ine imwe MPPT, mbiri mbiri MPPT, uye shoma shoma yetatu MPPT.Kazhinji kutaura, mainverters ane rated simba re1kW～3kW anotora imwe MPPT dhizaini;iwo ma inverters ane akayereswa simba re3kW～30kW anotora maviri maviri MPPT kana mashoma matatu MPPT.
Kune yekunze DC isolator switch, unogona kusarudza mapango mana, mapango matanhatu, mapango masere emaseti akawanda emapanera ezuva kana mapango maviri seti yemapanera ezuva zvinoenderana neakasiyana masisitimu magadzirirwo.
Iyo PV DC isolator switch inofanirwa kusarudzwa zvinoenderana neyakakura voltage uye ikozvino yetambo yepaneru.Kana mushandisi achiziva ma parameter e photovoltaic inverters, kunyanya vanogadzira inverter, kuitira kuti vakwanise kuchengetedza mutengo, vanogona kusarudza zvinoenderana neinopinza DC voltage uye ikozvino curve kuve nechokwadi kuti inogona kushandiswa mumamiriro ese ekunze uye tembiricha.
BS 7671 inotaura kuti kupatsanura ma switch anoenderana ne EN 60947-3 akakodzera mafotovoltaic system.Iyo yakatemerwa kukosha kweiyo isolator switch inofanirwa kufunga nezve yakanyanya voltage uye yazvino yeiyo photovoltaic tambo kuti ive yega, uye wozogadzirisa ma paramita aya zvichienderana nekuchengetedza chinhu chinotsanangurwa nechiyero chazvino.Iyi inofanirwa kunge iri iyo shoma rating inodiwa kune isolator switch.
Iyo tembiricha yenzvimbo yekushanda, mwero wekudzivirira uye nhanho yekudzivirira moto inofanirwa kutariswa zvinoenderana nenharaunda.Kazhinji yakanaka PV DC isolator switch inogona kushandiswa zvakachengeteka pane ambient tembiricha ye -40°C kusvika 60°C.Kazhinji, mwero wekudzivirira wekunze DC yekuparadzanisa switch inofanira kusvika IP65;iyo yakavakirwa-mukati DC isolator switch inofanirwa kuve nechokwadi chekuti michina inosvika IP65.Chiyero chemoto chebhokisi reimba kana mutumbi mukuru uchaenderana neUL 94V-0, uye mubato uchaenderana neUL 94V-2.
Vashandisi vanogona kusarudza iyo yakakodzera modhi zvinoenderana nezvinodiwa chaizvo.Kazhinji, kune kuisirwa kwepaneru, kuisirwa base uye kuiswa kwegomba rimwe chete.
