Hoʻokuʻu ʻana o ka Hui | Wuxi, Kina | Iune 10, 2020

Loaʻa i ka DMJ-MC metalized film capacitor ma CRE nā pono hoʻokūkū ma mua o ka electrolytic capacitor kuʻuna i nā mea hoʻololi alapine (frequency converters) a me nā inverters ma muli o kona nui liʻiliʻi, ka nui o ka ikehu, ke kū'ē ʻana i ke voltage kiʻekiʻe, ka lōʻihi o ke ola, ka haʻahaʻa o ke kumukūʻai hana a me ka hiki ke ho'ōla pono'ī.

 

Wuxi, Jiangsu (Iune 10, 2020) - Ua loea ʻo Wuxi CRE New Energy i ka hana ʻana i nā capacitors kiʻiʻoniʻoni metalized mai ka makahiki 2011. Hoʻohana nui ʻia ma ke kaapuni DC-Link no ke kānana a me ke kumu mālama ikehu, ʻo DMJ-MC series ke ʻano o nā capacitors kiʻiʻoniʻoni metalized like ʻole ma CRE.

 

Me kahi pae volta i helu ʻia mai 450 a 4000 VDC a me kahi pae capacitance mai 50-4000 UF, ua lako ka capacitor DMJ-MC me nā nati keleawe a me ka uhi plastik no ka insulation. Hoʻopili ʻia ia i loko o ka cylinder alumini a hoʻopiha ʻia e ka resin maloʻo. ʻO ka capacitance nui aʻe i ka nui liʻiliʻi, hiki ke hoʻokomo maʻalahi ʻia ka capacitor DMJ-MC.

 

ʻO ka moʻo DMJ-MC, me nā capacitors kiʻiʻoniʻoni metalized ʻē aʻe ma CRE, hāʻawi i ka hana ʻoi aku ka maikaʻi ma nā mea hoʻololi alapine (frequency converters) a me nā inverters i hoʻohālikelike ʻia me ka capacitor electrolytic kuʻuna a ke pani nei i ka hoʻohana ʻana o ka mea hope.

 

ʻO ka waiwai dielectric o ka alumini oxide a me ke conductivity o ka electrolyte e kaupalena i ke kū'ē voltage kiʻekiʻe loa o ka electrolytic capacitor. ʻO ka capacitor electrolytic kuʻuna he voltage helu kiʻekiʻe loa o 500V a i ʻole 600V. Ke koi ʻia ka voltage kiʻekiʻe, pono e hoʻopili ʻia nā capacitors electrolytic he nui ma ke ʻano he moʻo me ke kū'ē kūpono no ke kaulike ʻana i ka voltage. E hoʻonui kēia i ka paʻa ʻole o nā capacitors a hiki paha ke alakaʻi i ka pahū a i ʻole ka electrolyte leakage, kahi mea ʻino i ke kaiapuni.

 

Eia nō naʻe, ʻo ka moʻo DMJ-MC, ma ke ʻano he capacitor kiʻiʻoniʻoni metalized maʻamau ma CRE, hāʻawi i nā hoʻonā i nā palena a me nā hemahema āpau o nā capacitors electrolytic kuʻuna i ʻōlelo ʻia ma luna. ʻO ka mea mua, ʻaʻole ia e hoʻohana i nā electrolytes kemika ʻo ia hoʻi he ʻoi aku ka launa pū me ke kaiapuni. Eia kekahi, hāʻawi ia i ke kū'ē ʻana i ka voltage kiʻekiʻe no kēlā me kēia capacitor me kahi pae voltage i helu ʻia mai 450 a 4000 VDC. ʻO ke kū'ē voltage kiʻekiʻe loa ma kahi o 7 mau manawa ʻoi aku ka kiʻekiʻe ma mua o ka capacitor electrolytic kuʻuna. Eia kekahi, he liʻiliʻi kona nui, māmā ke kaumaha a me ka nui o ka ikehu e alakaʻi ana i ka uku hana haʻahaʻa.

 

Eia kekahi, loaʻa i ka capacitor kiʻiʻoniʻoni metala DMJ-MC ka hiʻohiʻona o ka ho'ōla pono'ī, kahi hiki ke pale i ka hāʻule ʻana o ka catastrophic ke loaʻa kahi kīnā kūloko. Ua uhi ʻia ka kiʻiʻoniʻoni dielectric ma DMJ-MC me kahi papa metala lahilahi. Ke loaʻa kahi wahi nāwaliwali a haumia paha ma ka dielectric, e haki ana. ʻO ka ikehu i hoʻokuʻu ʻia e ka arc discharge ma ka haki ʻana e lawa ia e hoʻoheheʻe i ka papa metala a puni, hoʻokaʻawale i ka hemahema a hoʻōla pono i ka capacitor e mālama i ka hana. No laila, ʻoi aku ka lōʻihi o ke ola o DMJ-MC a me ka hilinaʻi kūpono me ka ʻole o ka hāʻule ʻana o ka catastrophic i hoʻohālikelike ʻia me nā capacitors electrolytic kuʻuna.

 

Loaʻa i ka DMJ-MC metalized film capacitor kahi ākea o nā noi e pili ana i nā ʻano mea hoʻololi alapine (frequency converters) a me nā inverters, inverter photovoltaic, mea hoʻololi mana makani, EVs, HEVs, SVG, SVC a me nā mea hana hoʻokele ikehu ʻē aʻe.

 

I nā makahiki 9 i hala iho nei, ua hoʻomaikaʻi ʻo Wuxi CRE New Energy i kāna ʻenehana capacitor kiʻiʻoniʻoni metalized a ua lilo ʻo ia i mea hana lako kumu (OEM) no ka ʻoihana uila kaulana ma ʻAmelika. ʻO ka capacitor kiʻiʻoniʻoni metalized DMJ-MC kekahi o nā huahana kaulana loa a kūʻai maikaʻi loa ʻia no ka mea hāʻawi ia i ka hana maikaʻi me nā pono hoʻokūkū he nui i ka wā e hoʻohana ʻia ai i nā mea hoʻololi alapine a me nā inverters. He hopena maʻamau, hilinaʻi a maikaʻi hoʻi no ka mākeke koi.
