Ko photovoltaic inverters inomira sei kupisa kunopisa kunodarika 40°C?

Zhizha rino, matunhu mazhinji kuChina akapa chenjedzo dzvuku dzekupisa kwakanyanya, nekupisa kwemasikati mumaguta mazhinji kunosvika 40°C, zvichigadzira mamiriro ezvinhu anoyeuchidza 'vira romoto'. Mumamiriro ekudzikira akadai, kunyangwe vanhu vanonetsekana kusiya nzvimbo dzine mhepo inotonhorera, nepo photovoltaic midziyo inoshanda kunze inotarisana nematambudziko makuru. Kunyanya zvine chekuita ne "core brain" yephotovoltaic system - iyo inverter. Midziyo iyi inokunda sei kupisa kwakanyanya?

Zvinokuvadza sei tembiricha yepamusoro kune inverter zvikamu?

Photovoltaic inverters zvigadziriso zvakaoma zvinobatanidza akawanda akanyanya-chaiyo emagetsi zvikamu, zvinosanganisira zvakakosha zvikamu senge inductors, capacitors, uye simba semiconductor modules. Tembiricha yepamusoro haingokanganisa kushanda zvakanaka kwezvikamu izvi asi zvakare inomhanyisa kuchembera, kupfupisa hupenyu hwavo, uye inogona kutokonzera kutadza kwemidziyo.

MaInductors: Munzvimbo dzine tembiricha yakakwira, maInductors anozadza magetsi zviri nyore, zvichideredza kuzara kwawo. Izvi zvinotungamira pakuwedzera kwesimba remagetsi, zvichiwedzera njodzi yekupfuudza simba remagetsi uye zvinogona kudzima michina yemagetsi.

MaCapacitors: Macapacitors eAluminium electrolytic, kunyanya, anonyanya kukanganiswa nekupisa. Data rinoratidza kuti pakuwedzera kwega kwega kwe10°C mukupisa kwekunze, hupenyu hwawo hunoderedzwa nehafu. Kunyangwe macapacitors efirimu achiratidza kusapisa kwakanyanya, mitengo nehukuru zvinodzikamisa kushandiswa kwawo zvakanyanya.

MaPower Modules: Kune ma power chips akadai seIGBTs neMOSFETs, 'junction temperature' inoshanda sechikamu chakakosha chekushanda. Kana tembiricha ye chips yadarika muganho wayo, 'thermal breakdown' inoitika, zvichikonzera kudzima kwe inverter zvakananga.

Dhizaini yeThermal: Chombo Chakavanzika cheMugadziri weInverter

Kuti ive nechokwadi chekushanda kwakadzikama munzvimbo dzepamusoro-tembiricha, mafotovoltaic inverters anoshandisa zvine hunyanzvi dhizaini manejimendi masisitimu. Nheyo yemusimboti ndeyekuchengetedza chikamu chese mukati meiyo inogamuchirwa tembiricha renji.

Common thermal management maitiro anosanganisira:

Masisitimu ekutonhodza mhepo: Ane mafeni akangwara anochinja-chinja kumhanya ayo anogadzirisa kufamba kwemhepo otomatiki zvichienderana nekushanduka-shanduka kwekupisa kwemukati, achienzanisa kutonhora kunochinja-chinja nekushanda nesimba uye kuderedza ruzha.

Kugadzirisa madhishi ekupisa: Kuvandudza mashandiro ekuchinjana kwekupisa nekuwedzera nzvimbo yedhishi rekupisa, kunatsa zvivakwa (semuenzaniso, magadzirirwo emafin ane serrated), uye kushandisa zvinhu zvinofambisa kupisa zvakanyanya.

Dhizaini yechassis yakabatana: Zvizhinji zviri kuwedzera kuti ma inverter epamusoro-soro anoshandisa aluminium alloy die-casting kubatanidza zvivakwa zvekupisa nechassis. Pamwe chete ne thermal silicone gel uye heat spreaders, izvi zvinobatsira kubvisa kupisa nekukurumidza.

Semuyenzaniso, mamwe ma brand' 'yepamusoro-tembiricha anoshivirira' inverters anoratidza maviri-inishuwarenzi kutonhora masisitimu anosanganisira hombe-nzvimbo yekumashure zvimbi uye mafeni akangwara. Izvi hazvingowedzere kuchinjika munzvimbo dzakanyanyisa asi zvakare inovimbisa kugadzikana kwenguva refu kwehurongwa.

Inverter Heat Dziviriro Strategies: Kutanga Kuisa uye Kugadzirisa

Beyond inherent high-temperature kuramba, yakakwana yekumisikidza nharaunda uye nekuchenjera maitiro ekugadzirisa akakosha zvakaenzana.

Kusarudza Nzvimbo Zvakakosha: Isa ma inverter munzvimbo dzine mhepo inofefetera zvakanaka dzakadzivirirwa kubva kuzuva rakananga. Pakuisa panze, funga nezvekuwedzera mimvuri yezuva kuti uderedze kusvibiswa nezuva nemvura. Pakuisa ma inverter akawanda padivi nepadivi, iva nechokwadi chekuti pane nzvimbo yakakwana kuti ubvise kupisa zvinobudirira.

Kuchenesa Nguva Dzose Kwakakosha: Munzvimbo dzinopisa zvakanyanya, guruva rinoungana nyore nyore pamasinki ekupisa nemafeni, zvichikanganisa kushanda zvakanaka kwekutonhodza. Zvinokurudzirwa kuti uongorore sisitimu yekutonhodza kanenge mwedzi wega wega kuti uone kana guruva rakaungana here kana kuti zvinhu zvakavharika, wobva wachenesa nekukurumidza kana zvichidikanwa.

Tarisa mamiriro ekushanda: Gara uchitarisa chiratidziro che inverter, zviratidzo zve LED, uye masisitimu ekutarisa ari kure kuti uone zviziviso zvakaita se 'kunyevera pamusoro pekupisa kwakanyanya' kana 'kusashanda zvakanaka kwefeni'. Kana paine zvisina kunaka, ferefeta nekukurumidza uye bata nyanzvi mushure mekutengesa kana zvichidikanwa.

Pfungwa dzekupedzisira: Kupisa kwakanyanya hakusi kuita kwaMwari, asi bvunzo ye litmus yekugadzira system

Sezvo kupisa kwezhizha kunowedzera gore negore muChina yose, inverter's thermal resilience yave chiratidzo chakakosha chekuvimbika kwechigadzirwa. Kune varidzi vePV chirimwa uye vashandi veO&M, kusarudza epamusoro-mhando inverters ane yepamusoro yekupisa manejimendi kwakakosha pakuona kuita pundutso uye kugadzikana.

Kupisa kwakanyanya hakusi muvengi-kusagadzirira. Ngatichengetedzei maPV inverters edu ne 'heatwave shield' kuti timire mafungu anopisa ezhizha, kuve nechokwadi chekuti kilowatt-awa yega yega yegirini simba inounzwa zvakavimbika.
