一、Photovoltaic system boom
Me ka hoʻonui nui ʻana i ka mālama ʻana i ke kaiapuni a puni ka honua, ua hoʻohana nui ʻia nā ʻōnaehana photovoltaic ma nā ʻano āpau.I ka mākeke uila, ʻaʻole hiki i nā ʻōnaehana photovoltaic ke hāʻawi wale i ka uila i nā kūlanakauhale, akā hāʻawi pū kekahi i nā lawelawe kukui a me nā kamaʻilio i nā wahi mamao.I ka manawa like, ʻo nā ʻōnaehana photovoltaic he haʻahaʻa haʻahaʻa nā kumukūʻai hoʻonohonoho a me nā kumukūʻai haʻahaʻa haʻahaʻa, no laila makemake ʻia lākou e nā ʻoihana a me nā keʻena aupuni.
二、Photovoltaic inverters loaʻa nā pilikia e hoʻopau ʻia
ʻO ka mea hoʻohuli kiʻi kiʻi kiʻi he mea ia e hoʻohuli ai i ke au pololei i hana ʻia e nā panela photovoltaic i ke au hou.Mālama ia i ka volta a me ka puka o kēia manawa e nā panela photovoltaic ma o ka algorithm tracking point mana kiʻekiʻe, ʻike i ka piʻi ʻana a me ka hāʻule ʻana o ka volta o ke au pololei, a hoʻololi iā ia i kahi lako mana pololei o kēia manawa.A laila, hoʻololi ka inverter i ka mana DC i ka mana AC me ka hoʻohana ʻana i ka ʻenehana modulation pulse laula kiʻekiʻe, a hoʻomaʻamaʻa iā ia ma o kahi kānana hoʻopuka e hōʻoia i ka maikaʻi a me ka paʻa o ka hopena o kēia manawa.ʻO ka hope loa, hoʻopili ka mea hoʻohuli i ka mana AC i ka mana mana e hoʻokō ai i nā pono uila o ka hale a i ʻole ka ʻoihana.Ma kēia ʻano, hana nui nā mea hoʻohuli photovoltaic i ka hoʻohuli ʻana i ka ikehu o ka lā i uila hiki ke hoʻohana.
I kēia manawa, ʻo ka 1000 ~ 2200W photovoltaic inverter maʻamau i hoʻohana ʻia ma ka hopena hoʻokomo o ka ʻōnaehana hana mana photovoltaic he kiʻekiʻe kiʻekiʻe a hiki i 580V.Eia naʻe, ʻaʻole hiki i ka 500V output capacitor ke hoʻokō hou i nā pono o nā inverters photovoltaic.I waena o lākou, he hana koʻikoʻi nā capacitors electrolytic aluminika, ʻaʻole hiki ke hāʻawi wale i nā kānana pono a me nā hana mālama, akā e hōʻoia pū i ka hilinaʻi a me ka pono o ka ʻōnaehana holoʻokoʻa.Inā ʻaʻole lawa ka puʻupuʻu hoʻopuka, e hoʻomāhana ka capacitor, wāwahi, a pōʻino.No laila, pono e noʻonoʻo pono i nā kumu like ʻole i ke koho ʻana i kahi capacitor electrolytic, a koho i ka huahana kūpono loa e hōʻoia i ka hana kūpono o ka ʻōnaehana a loaʻa ka hana maikaʻi loa.
三、Yongming high-voltage lead-type capacitors hoʻoponopono i ka pilikia "kiʻekiʻe voltage".
I mea e hoʻoponopono ai i ka pilikia kiʻekiʻe-volta o photovoltaic inverters, Shanghai Yongming hoʻokuʻu kiʻekiʻe-voltage alakaʻi-type LKZ series aluminum electrolytic capacitors.Loaʻa i ka ʻohana nā hiʻohiʻona hoʻokō pololei a ke hana nei ma luna o kahi ākea o nā volta hoʻokomo, e komo pū ana me nā volta kiʻekiʻe a hiki i 580V.Hiki i ka hana maikaʻi loa o nā capacitors series LKZ ke hoʻomaikaʻi i ka paʻa a me ka pono o nā inverters photovoltaic a hāʻawi i nā mea kūʻai aku i nā hopena maikaʻi loa.
1、Ka piʻi ikaika loa a me ka pale ʻana i ka hopena: LKZ series aluminum electrolytic capacitors hiki ke hiki i ka 600V voltage, hiki ke maʻalahi i ka volta kiʻekiʻe a me ka nui o kēia manawa i ka wā o ka hoʻopuka.
2、Ultra-ha'aha'a kū'ē kū'ē a me ka maikaʻi haʻahaʻa haʻahaʻa hiʻona: Hoʻohālikelike me Iapana capacitors o ka like kiko'ī, i ka impedance o Yongming capacitors ua ho'ēmi 'ia e ma kahi o 15% ~ 20%, ka mea e hōʻoia i ka liʻiliʻi wela piʻi, nui ripple kū'ē a me - 40 ℃ ka hana o ka capacitor i ka wā e hana ai.ʻO nā hiʻohiʻona haʻahaʻa haʻahaʻa, i ʻole e hāʻule ka capacitor i ka wā mua o ka hana lōʻihi.
3, ʻOi aku ka nui o ka hiki ke kiʻekiʻe: ʻOi aku ka nui o nā capacitors electrolytic Yongming ma mua o 20% ma mua o nā capacitors Iapana o ka kikoʻī like a me ka nui, me ke kiʻekiʻe kiʻekiʻe a me ka hopena kānana maikaʻi;i ka manawa like, ma lalo o nā koi mana like, me ka hoʻohana ʻana iā Yongming Nui ka mana electrolytic capacitors hiki ke hōʻemi i nā kumukūʻai o nā mea kūʻai aku ma ke ʻano o ka capacitance.
4、Ka hilinaʻi kiʻekiʻe: Hāʻawi nā capacitors electrolytic o Yongming i kahi hōʻoia ʻoi aku ka paʻa a me ka hilinaʻi o nā ʻāpana uila nui e like me nā photovoltaic inverters, e hoʻomaikaʻi i ka hana o ka ʻōnaehana photovoltaic holoʻokoʻa.
Helu uila: 550~600V
Ka nui o ka mana: 82 ~ 220μF
Hana wela: -40~105 ℃
Ka lōʻihi o ke ola: 12000~15000H
四、E hana i nā capacitors kūloko kiʻekiʻe a holomua i ka mākeke honua
Ma ke ʻano he capacitor hou home, ʻo Yongming wai ke alakaʻi alumini electrolytic capacitor he mau mea maikaʻi loa i ka hoʻohana ʻana i nā inverters photovoltaic, e hāʻawi ana i kahi hōʻoia ikaika no ka paʻa ʻana o ka ʻōnaehana photovoltaic, a ua hoʻohālikelike ʻia kāna hana holoʻokoʻa me nā capacitors Iapana..
