Gwaro reDC neAC SPD Type 2 reSolar neMagetsi Systems

Ndakaona chiitiko chimwe chete chekukwira kwemvura chichibvisa mwedzi yakawanda yekugadzirwa, saka ndinogara ndichirapa Chishandiso Chinodzivirira Kukwira sechinhu chikuru chekugadzira, kwete chinhu chekuwedzera.

Gwaro reDC neAC SPD Type 2 rinotsanangura kuti sei Chishandiso Chinodzivirira Kukwira Mhinduro dzinodzivirira masisitimu ezuva nemagetsi kubva pakudarika simba remagetsi kwenguva pfupi, dzinovandudza nguva yekushanda, uye dzinoderedza mari yekuchengetedza nekubhadhara nguva refu.

Kana uchida kutumirwa kwezvinhu zvinofanotaurwa, mhando yakagadzikana, uye mutengo wakaderera wekuva muridzi, kunzwisisa kuti Type 2 SPDs ndiyo nzvimbo yakangwara yekutanga.

Chii chinonzi DC Surge Protection Device?

Ndinowanzoona njodzi dzeDC dzichiregeredzwa kusvika michina yakundikana, saka ndinogara ndichitanga ongororo dzesystem kubva kudivi reDC.

A Mudziyo wekudzivirira kukwira kwemvura weDC inoderedza kukwira kwemagetsi kwenguva pfupi pamasekete eDC nekutsausa simba rekukwira kwemagetsi pasi zvakachengeteka, ichidzivirira michina yakabatana kubva mukukuvadzwa.

Ndinoona dziviriro yeDC surge sedanho rekutanga rekudzivirira mumagetsi ezuva nemaindasitiri. Macircuit eDC anoonekwa pachena, akareba, uye anowanzoiswa panze. Izvi zvinoita kuti ave panjodzi huru yekusangana nemheni inokonzerwa nekukwira kwemhepo uye kuchinja kwemhepo. Chishandiso Chinodzivirira Kukwira Iyo yakaiswa kudivi reDC inoita shanduko mukati memasekonzi mashoma uye inosunga ma voltage spikes ane njodzi isati yasvika kumagetsi anonzwa.

Mukuisa chaiko, maDC SPD anodzivirira ma inverter, magetsi eDC, mabhatiri, uye ma control circuits. Pasina iwo, kukwira kamwe chete kunogona kukonzera kukanganiswa kwe insulation, kutadza kushanda zvakanaka kwe semiconductor, kana kudzikira kwe permanent performance. Ndakaona izvi zvichiitika mukudzivirira kukwira kwema surge kumafekitori uko nguva yekushanda inokurumidza kuva nguva yekunonoka kusvika.

Dhizaini yakanaka yeDC SPD inogara ichifunga nezvemhando yegrounding, kureba kwetambo, uye nzvimbo yekuisa. Handimbooni dziviriro yeDC sechinhu chakazvimiririra. Inofanira kushanda sechikamu chegrounding nebonding system yese.

DC SPD Rudzi rwechipiri yeSolar neMasisitimu eMagetsi

Ndinokurudzira mhando yechipiri yeDC SPDs munzvimbo zhinji dzinoshandiswa pakuparadzira simba rezuva nemagetsi.

Midziyo yeDC SPD Type 2 yakagadzirirwa kuchengetedza masisitimu eDC kubva kumhepo dzinokonzereswa nemheni uye mavoltage anochinja-chinja mumasevhisi echikamu chekugovera.

Mumapurojekiti angu, maSDD erudzi rwechipiri (Type 2 DC) ndiwo anonyanya kushandiswa. Anoiswa pasi pesystem huru yekudzivirira mheni uye anobata zviitiko zvinodzokorora zvekuputika zvinobudirira. Kusiyana nemidziyo yerudzi rwekutanga, akagadzirirwa mabhodhi ekuparadzira, mabhokisi ekubatanidza, uye ma inverter inputs.

Ini ndinoda dziviriro yerudzi rwechipiri yemagetsi ezuva epadenga, ePV yekutengeserana, uye akawanda mashandisirwo eSPD emaindasitiri. Anopa chiyero chakasimba pakati pehuwandu hwedziviriro nemutengo. Izvi zvinokosha kune vatariri vekutenga vanoda mitengo inofungidzirwa pasina kukanganisa kuvimbika.

Kubva pane zvakaitika, mhando yechipiri yeDC SPDs inoderedza zvikuru zvikanganiso zveinverter zvinonetsa uye kuvharwa kusingatsananguriki. Inowedzerawo hupenyu hwemidziyo nekuderedza kushushikana kwemagetsi kwakabatana. Izvi zvinoreva kuti mari shoma yekugadzirisa uye kugadzikana kwesystem kuri nani.

Kutsanangurwa kweDC SPD Voltage Ratings

Ndinoona zvikanganiso zvekuyera voltage kakawanda kupfuura chero imwe zvikanganiso zvekusarudza SPD.

Kuyerwa kwemagetsi eDC SPD kunofanirwa kupfuura voltage yepamusoro inogoneka yeDC system kudzivirira kutadza kushanda zvakanaka uye kurasikirwa nedziviriro.

Handimbosarudzi SPD zvichibva pamagetsi emagetsi chete. Tembiricha, mamiriro ekushanda, uye kuwedzera kwesystem zvese zvinokanganisa mazinga emagetsi chaiwo. Semuenzaniso, kutonhora kunogona kusundira voltage yePV open-circuit kure kupfuura nameplate values.

Heino maitiro andinowanzo enzanisa DC voltage ratings:

Kushandisa voltage rating chaiyo kunoita kuti Chishandiso Chinodzivirira Kukwira inoita zvakanaka nekufamba kwenguva pane kukundikana chinyararire mushure mezviitiko zvishoma.

Kugadziriswa kwePole kweDC Surge Protection Devices

Ndinogara ndichiongorora magadzirirwo ematanda ndisati ndabvumidza chero DC SPD.

Kugadzika kwedanda rekudzivirira surge device reDC kunotsanangura kuti mangani maconductors akachengetedzwa uye kuti simba re surge rinoburitswa sei pasi.

Masisitimu mazhinji ezuva anoshandisa 2P DC SPDs kudzivirira maconductor akanaka neasina kunaka. Mumasisitimu akaomarara, nzira dzakasiyana dzekuisa pasi dzingada mamwe mapango. Kusarudza magadzirirwo asina kunaka kunogona kusiya chikamu chesisitimu chakavhurika.

Mumapurojekiti eSPD emaindasitiri, ndinotanga ndaongorora topology yegrounding. Izvi zvinodzivirira njodzi dzakavanda uye zvinoita kuti dziviriro irambe ichishanda zvakanaka.

Chii chinonzi AC Surge Protection Device?

Ndinoona dziviriro yeAC sechikamu chechipiri chakakosha chedziviriro.

An Mudziyo wekudzivirira kukwira kweAC inoderedza kupfupfudzika kwesimba remagetsi eAC, ichidzivirira mitoro nemidziyo yekuparadzira kubva mukukuvadzwa.

MaAC SPD anodzivirira kubva pakukwira kwesimba kunopinda kubva pagrid kana kugadzirwa mukati nekuchinjana kwemagetsi. Mumasystem ezuva, anodzivirira ma inverter outputs, switchboards, uye downstream loads.

Ndinogara ndichibatanidza AC neDC SPDs pamwe chete. Dziviriro yakaparadzaniswa haishande zvakanaka senzira yehurongwa hwakarongeka.

AC SPD yeSisitimu yeSitemu yeSitemu imwe chete neSitemu nhatu dzeSitemu

Ndinogadzirisa sarudzo yeAC SPD zvichienderana nesystem topology.

Ma AC SPD anosarudzwa zvichienderana nechimiro chechikamu kuti ave nechokwadi chekudzivirira kukwira kwemvura kwakaringana uye kwakakwana.

Masisitimu echikamu chimwe chete anowanzo shandisa magadzirirwo ari nyore, nepo masisitimu echikamu chetatu achida nzira dzakaoma dzekudzivirira. Ini ndinotarisa pakuenzana uye pasi kuti ndidzivise kushushikana kusina kuenzana panguva yezviitiko zvekukwira kwemvura.

Maitiro aya anoshanda zvakanyanya pakudzivirira kukwira kwemvura mumafekitori uko mutoro wakaenzana uye kuenderera mberi kwawo kunokosha.

Kuyera uye Kugadzirisa Voltage yeAC SPD

Ndinogara ndichienzanisa ma AC voltage ratings nemamiriro chaiwo ekushanda, kwete chete mavara.

Kuongororwa kwemagetsi eAC SPD uye magadzirirwo azvo zvinotsanangura kuti mafungu anovharirwa sei mudzimba, mabhizinesi, uye maindasitiri.

Heino rondedzero iri nyore yandinowanzo shandisa:

Kugadziriswa kwakarurama kunoita kuti kusvetuka kwemvura kuenderane nekwakavimbika uye kunodzivirira kukwegura kweSPD nguva isati yakwana.

Kubatanidza AC neDC SPD muSolar Systems

Ndinogara ndichigadzira dziviriro yekuputika kwemhepo senzira yakarongeka.

Kushandisa AC neDC SPDs pamwe chete kunogadzira dziviriro ine zvikamu zvinoderedza voltage inosara uye kunovandudza kuvimbika kwehurongwa hwese.

Kubatanidza zvinoreva kuisa maDC SPD pedyo nemaPV arrays nema inverters, uye ma AC SPDs panzvimbo dzekugovera. Iyi nzira ine layered ndiyo yakajairika mukugadzira kwehunyanzvi hwe surge arrester uye inopa njodzi yakaderera yenguva refu.

Mhedziso

Sarudza chakarurama Chishandiso Chinodzivirira Kukwira ronga izvozvi kuchengetedza hurongwa hwako, purogiramu yako, uye mari yako yenguva refu.

Mibvunzo Inowanzo bvunzwa

Mubvunzo wekutanga: Ko mhando yechipiri yeSPD yakakwana here kune akawanda masisitimu ezuva?

Ehe. Mhando yechipiri yeSPDs inovhara njodzi zhinji dzinokonzereswa nekukwira kwesimba muzvimiro zvakajairwa.

Mubvunzo wechipiri: Ndingashandisa ma AC SPDs here pamasekete eDC?

Kwete. AC neDC SPDs zvakagadzirwa zvakasiyana uye hazvichinjiki.

Mubvunzo wechitatu: Kusimbisa mashandiro eSPD kwakakosha sei?

Hunhu hwekudzika pasi hunokanganisa zvakananga kuti simba remagetsi rinoburitswa sei.

Mubvunzo wechina: MaSPD anoda kugadziriswa here?

Dzinofanira kuongororwa nguva nenguva uye kutsiviwa mushure mekunge dzaratidza kuti dzapera.

Mubvunzo wechishanu: Sei tichironga AC neDC SPDs?

Kubatana kunoderedza magetsi akasara uye kunovandudza kuvimbika kwesystem.
