Ndi chitukuko chofulumira cha makampani opanga mphamvu zatsopano, magetsi a photovoltaic amagwiritsidwa ntchito kwambiri. Monga chigawo chachikulu cha machitidwe opangira magetsi a photovoltaic, ma inverters a photovoltaic amagwiritsidwa ntchito m'madera akunja, ndipo amayesedwa mwaukali kwambiri komanso ngakhale madera ovuta.
Kwa ma inverters akunja a PV, kapangidwe kake kamayenera kukumana ndi IP65. Pokhapokha pofika mulingo uwu pomwe ma inverters athu amatha kugwira ntchito motetezeka komanso moyenera. Mulingo wa IP ndi wa chitetezo cha zinthu zakunja zomwe zili m'kati mwa zida zamagetsi. Gwero ndi muyezo wa International Electrotechnical Commission wa IEC 60529. Mulingo uwu udakhazikitsidwanso ngati mulingo wadziko la US mu 2004. Nthawi zambiri timanena kuti IP65 level, IP ndi chidule cha Ingress Protection, pomwe 6 ndiye mulingo wafumbi, (6) : kuletsa kwathunthu fumbi kulowa); 5 ndiye mulingo wosalowa madzi, (5: kuthira madzi popanda kuwonongeka).
Kuti mukwaniritse zofunikira zomwe zili pamwambazi, zofunikira za mapangidwe a photovoltaic inverters ndizovuta kwambiri komanso zanzeru. Ilinso ndi vuto lomwe ndi losavuta kuyambitsa zovuta pamapulogalamu am'munda. Ndiye timapanga bwanji chida cha inverter choyenerera?
Pakalipano, pali mitundu iwiri ya njira zotetezera zomwe zimagwiritsidwa ntchito poteteza pakati pa chivundikiro chapamwamba ndi bokosi la inverter mu makampani. Imodzi ndiyo kugwiritsa ntchito mphete ya silicone yopanda madzi. Mtundu uwu wa mphete ya silikoni yopanda madzi nthawi zambiri imakhala 2mm yokhuthala ndipo imadutsa pachivundikiro chapamwamba ndi bokosi. Kukanikiza kukwaniritsa madzi ndi fumbi zotsatira. Mtundu uwu wachitetezo umachepa ndi kuchuluka kwa mapindikidwe ndi kuuma kwa mphete ya mphira ya silikoni yopanda madzi, ndipo ndiyoyenera mabokosi ang'onoang'ono a inverter a 1-2 KW. Makabati akuluakulu amakhala ndi zoopsa zambiri zobisika muchitetezo chawo.
Chithunzi chotsatirachi chikuwonetsa:
Zinazo zimatetezedwa ndi German Lanpu (RAMPF) polyurethane styrofoam, yomwe imagwiritsa ntchito manambala kuwongolera thovu ndikumangika mwachindunji ku zigawo zamapangidwe monga chivundikiro chapamwamba, ndipo mapindikidwe ake amatha kufika 50%. Pamwambapa, ndizoyenera makamaka pakupanga chitetezo cha ma inverters athu apakatikati ndi akulu.
Chithunzi chotsatirachi chikuwonetsa:
Panthawi imodzimodziyo, chofunika kwambiri, pakupanga mapangidwe, pofuna kuonetsetsa kuti mapangidwe amadzimadzi amphamvu kwambiri, groove yopanda madzi idzapangidwira pakati pa chivundikiro chapamwamba cha photovoltaic inverter chassis ndi bokosi kuti zitsimikizire kuti ngakhale madzi amadzimadzi. imadutsa pachivundikiro chapamwamba ndi bokosi. Mu inverter pakati pa thupi, mudzawongoleredwa kudzera mu thanki yamadzi kunja kwa madontho amadzi, ndikupewa kulowa m'bokosi.
M'zaka zaposachedwapa, pakhala pali mpikisano woopsa pamsika wa photovoltaic. Opanga ma inverter ena asintha zina ndikusintha kuchokera pamapangidwe achitetezo ndi kugwiritsa ntchito zinthu kuti athe kuwongolera ndalama. Mwachitsanzo, chithunzi chotsatirachi chikuwonetsa:
Mbali yakumanzere ndi yochepetsera mtengo. Bokosi la bokosi limapindika, ndipo mtengo wake umayendetsedwa kuchokera pazitsulo zachitsulo ndi ndondomekoyi. Poyerekeza ndi bokosi lopinda katatu lomwe lili kumanja, mwachiwonekere pali malo ocheperako olowera m'bokosilo. Mphamvu ya thupi imakhalanso yotsika kwambiri, ndipo mapangidwewa amabweretsa mwayi waukulu wogwiritsidwa ntchito popanga madzi a inverter.
Kuphatikiza apo, chifukwa mawonekedwe a bokosi la inverter amakwaniritsa chitetezo cha IP65, ndipo kutentha kwamkati kwa inverter kumawonjezeka panthawi yogwira ntchito, kusiyana kwapakatikati chifukwa cha kutentha kwamkati ndi kusintha kwakunja kwachilengedwe kudzatsogolera ku Madzi kulowa ndikuwononga chinsinsi chamagetsi. zigawo. Kuti tipewe vutoli, nthawi zambiri timayika valavu yopumira madzi pabokosi la inverter. Valavu yopanda madzi komanso yopumira imatha kufananiza bwino kupanikizika ndikuchepetsa chodabwitsa cha condensation mu chipangizo chosindikizidwa, ndikuletsa kulowa kwa fumbi ndi madzi. Pofuna kukonza chitetezo, kudalirika ndi moyo wautumiki wa zinthu za inverter.
Choncho, tingathe kuona kuti oyenerera photovoltaic inverter structural kamangidwe amafuna mosamala ndi okhwima kamangidwe ndi kusankha mosasamala kanthu kamangidwe ka chassis kapangidwe kapena zipangizo ntchito. Apo ayi, imachepetsedwa mwachimbulimbuli kuti iwononge ndalama. Zomwe zimapangidwira zimangobweretsa zoopsa zazikulu zobisika kuntchito yokhazikika kwa nthawi yayitali ya photovoltaic inverters.
