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.

Inductors: Munzvimbo dzepamusoro-tembiricha, ma inductors anozadza zviri nyore, achideredza yavo saturated inductance. Izvi zvinotungamira kukuwedzera kwepamusoro kwazvino, kuwedzera njodzi yekupfuura uye inogona kupisa magetsi emagetsi.

Capacitors: Aluminium electrolytic capacitors, kunyanya, yakanyanya kupisa-sensitive. Data inoratidza kuti kune yega yega 10 ° C yekuwedzera kweambient tembiricha, hupenyu hwavo hwakapetwa nepakati. Kunyangwe mafirimu capacitor anoratidza kukwirira kupisa kupisa, mutengo uye saizi zvipingaidzo zvinodzikamisa kutorwa kwavo kwakapararira.

Power modules: Kune machipisi emagetsi senge IGBTs uye MOSFETs, iyo 'junction tembiricha' inoshanda seyakakosha kuita chikumbaridzo. Kana iyo chip tembiricha yadarika muganhu wayo, 'kuparara kwemafuta' kunoitika, zvichikonzera kuvharika kwe inverter.

Thermal Design: Iyo Inverter Mugadziri Chakavanzika Weapon

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:

Mhepo inotonhorera masisitimu: Yakashongedzerwa neakangwara anochinja-kumhanya mafeni anogadzirisa otomatiki mafambiro emhepo zvichienderana nekuchinja kwekushisa kwemukati, kuenzanisa kutonhora kwesimba nekuita kwesimba uye kuderedza ruzha.

Heat sink optimization: Kuvandudza kupisa kwekuchinjana nekuwedzera kupisa sink pamusoro penzvimbo, kunatsa zvimiro (semuenzaniso, serrated fin dhizaini), uye kushandisa yakakwirira-thermal-conductivity zvinhu.

Yakabatanidzwa chassis dhizaini: Nekuwedzera, ma premium inverters anoshandisa aluminium alloy kufa-casting kusanganisa kupisa kupisa zvimiro nechassis. Yakasanganiswa neiyo thermal silicone gel uye zvinoparadzira kupisa, izvi zvinofambisa kukurumidza kupisa kubviswa.

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.

Sarudzo Yenzvimbo: Isa ma inverters munzvimbo dzinofefetera zvakanaka dzakadzivirirwa kubva kuzuva rakananga. Pakuisa kunze, funga kuwedzera sunshades kuderedza kuratidzwa kwezuva nemvura. Paunenge uchiisa akawanda inverters padivi-ne-parutivi, ita shuwa nzvimbo yakakwana yekufambisa inoshanda kupisa kupisa.

Kugara Kucheneswa kwakakosha: Munzvimbo dzepamusoro-tembiricha, huruva inoungana zviri nyore pamadhishi ekupisa uye mafeni, zvichikanganisa kutonhora kwakanaka. Zvinokurudzirwa kuongorora iyo yekutonhodza system mwedzi wega wega kuti iunganidze huruva kana kuvharika kwezvinhu zvekunze, kuita kuchenesa nekukurumidza pazvinenge zvichidikanwa.

Tarisa mamiriro ekushanda: Gara uchitarisa inverter kuratidza, LED zviratidzi, uye kure yekutarisa masisitimu kune yambiro senge 'yambiro yekudarika-tembiricha' kana 'fan malfunctions'. Kana paine kusawirirana kukamuka, tsvaga nekukurumidza uye ubate nyanzvi mushure mekutengesa-rutsigiro 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.
