Hoʻohana ʻia nā capacitors Power i hana ʻia i nā kaapuni DC-link

ʻO ka wehewehe pōkole:

DMJ-PC moʻo

ʻO nā capacitors kiʻiʻoniʻoni metallized kekahi o nā capacitors maʻamau i hoʻohana ʻia i nā kaapuni uila o kēia mau lā aʻo nā capacitors kiʻiʻoniʻoni haʻahaʻa e hoʻohana mau ʻia no ka wehe ʻana a me nā noi kānana.

Hoʻohana nui ʻia nā capacitors kiʻiʻoniʻoni mana i nā kaapuni DC-link, nā laser pulsed, nā uila X-ray, a me nā mea hoʻololi.

ʻOkoʻa nā ʻano hana o nā capacitors kiʻiʻoniʻoni ma muli o ka mea dielectric i hoʻohana ʻia a me ka ʻenehana hana i hoʻohana ʻia.ʻO kekahi o nā dielectrics kiʻiʻoniʻoni maʻamau i hoʻohana pinepine ʻia me ka polyethylene naphthalate (PEN), polyethylene terephthalate (PET), a me ka polypropylene (PP).

Hiki ke hoʻokaʻawale nui ʻia nā capacitors kiʻiʻoniʻoni i loko o ke kiʻiʻoniʻoni/foil a me nā capacitors kiʻiʻoniʻoni metallized.ʻO ke ʻano kumu o kahi kiʻiʻoniʻoni / foil capacitor ʻelua mau electrodes metala a me kahi dielectric kiʻiʻoniʻoni ma waena o lākou.Hāʻawi nā capacitors kiʻiʻoniʻoni/foil i ke kūpaʻa insulation kiʻekiʻe, hiki ke mālama i ka pulse kiʻekiʻe, hiki ke lawe i kēia manawa, a me ka paʻa capacitance maikaʻi.ʻAʻole like me nā capacitors kiʻiʻoniʻoni/foil, hoʻohana nā capacitor kiʻiʻoniʻoni metala i nā kiʻiʻoniʻoni i uhi ʻia metala e like me nā electrodes.Metallized film capacitors ua hoemi kino nui, a haawi kiʻekiʻe volumetric pono, maikaʻi capacitance paʻa, haʻahaʻa dielectric poho, a me ka maikaʻi loa ho'ōla waiwai.ʻO kekahi mau capacitors kahi hui o nā capacitors kiʻiʻoniʻoni/foil a me nā capacitors kiʻi metallized a me nā hiʻohiʻona hiʻohiʻona o nā ʻano ʻelua.ʻO nā waiwai hoʻōla ponoʻī o nā capacitors kiʻiʻoniʻoni metallized e kūpono iā lākou no kahi ākea ākea o nā noi, e komo pū ana me ke ola lōʻihi a me nā kaʻa kaʻa kaʻa ʻole benign.

ʻO ka hoʻōla ponoʻī ʻana i nā capacitors kiʻiʻoniʻoni metallized

ʻO nā dielectrics kiʻiʻoniʻoni plastik i hoʻohana mau ʻia i ka hana ʻana i nā capacitors kiʻiʻoniʻoni metala me ka polypropylene (PP), polyphenylene sulfide (PPS), polyester, a me ka pepa metala (MP).Loaʻa i kēia mau mea dielectric nā mana hoʻōla ponoʻī.

I ka wā e haki ai i loko o ka capacitor kiʻiʻoniʻoni metala, e hoʻoheheʻe ʻia ka ʻili metala lahilahi a puni ka wahi hewa.Hoʻopau kēia kaʻina vaporization i ka papa metala conductive ma kahi a puni ka hapa.Ma muli o ka wehe ʻia ʻana o ka mea conductive, ʻaʻole hiki ke hele i kahi kaapuni pōkole ma waena o nā papa.Mālama kēia i ka hemahema o ka ʻāpana.

ʻO ka hiki ke ho'ōla ponoʻī o kahi capacitor kiʻiʻoniʻoni metala ma muli o nā kumu he nui e pili ana i nā waiwai o ka mea dielectric a me ka mānoanoa o ka papa metala.Pono ke kaʻina vaporization i ka hāʻawi ʻana i ka oxygen a me nā mea dielectric me ka ʻike o ka oxygen kiʻekiʻe i loaʻa nā waiwai hoʻōla ponoʻī.ʻO kekahi o nā dielectrics kiʻiʻoniʻoni plastik i loaʻa nā hiʻohiʻona hoʻōla pilikino maikaʻi ʻo polypropylene, polyester a me ka polycarbonate.Ma ka ʻaoʻao ʻē aʻe, ʻo nā dielectrics kiʻiʻoniʻoni plastik me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa hoʻōla pilikino.ʻO ka polyphenylene sulfide (PPS) kekahi o ia mea dielectric.

Ma waho aʻe o ka hoʻonui ʻana i ka hilinaʻi, hiki i ka hiki ke hoʻōla ponoʻī i nā capacitors kiʻi metallized e kōkua i ka hoʻomaikaʻi ʻana i ko lākou ola hana.Eia nō naʻe, ʻo ka hoʻōla ponoʻī ʻana e hoʻemi i ka wahi electrode metallized i ka manawa.

I nā noi, ʻo kekahi o nā kūlana e hiki ai ke hoʻolōʻihi i ka hāʻule ʻana o kahi ʻāpana me nā wela kiʻekiʻe, nā uila kiʻekiʻe, ka uila, ka haʻahaʻa kiʻekiʻe, a me ka interference electromagnetic (EMI).

Ma waho aʻe o nā waiwai hoʻōla ponoʻī, loaʻa nā capacitors kiʻiʻoniʻoni polyester metallized i ka dielectric kiʻekiʻe, ke kūpaʻa wela maikaʻi, ka ikaika dielectric kiʻekiʻe, a me ka maikaʻi volumetric maikaʻi loa.ʻO kēia mau hiʻohiʻona e kūpono i kēia mau capacitors no nā noi kumu maʻamau.Hoʻohana nui ʻia nā capacitors polyester metallized no nā noi DC e like me ka pale ʻana, ke kaʻe ʻana, decoupling, a me ka hoʻopau ʻana i ka walaʻau.

Hāʻawi nā capacitors polypropylene metallized i ke kūpaʻa insulation kiʻekiʻe, haʻahaʻa haʻahaʻa dielectric absorption, haʻahaʻa dielectric poho, kiʻekiʻe dielectric ikaika, a lōʻihi ka paʻa.Hoʻohana nui ʻia kēia mau ʻāpana hoʻokaʻawale i nā noi i hoʻopili ʻia e like me nā kānana kānana, nā ballast kukui, a me nā kaapuni snubber.Hiki i nā capacitors kiʻiʻoniʻoni polypropylene metala ʻelua ke kū i ka volta kiʻekiʻe a me nā haʻahaʻa puʻupuʻu kiʻekiʻe, a ua kūpono lākou no nā noi me kahi kiʻekiʻe o nā pulu pali.Hoʻohana maʻamau ʻia kēia mau capacitors i nā mea hoʻokele kaʻa, snubbers, hoʻololi i nā lako mana, a me nā mea nānā.

Ka hopena

ʻO ka hilinaʻi a me ke ola hana o nā capacitors e hilinaʻi nui i kā lākou mau ʻano hoʻōla ponoʻī.ʻOi aku ka hilinaʻi o nā ʻāpana passive me nā ʻano hoʻōla pilikino maikaʻi a hāʻawi i kahi ola hana lōʻihi.ʻO nā hiʻohiʻona hoʻōla ponoʻī maikaʻi o nā capacitors kiʻiʻoniʻoni metallized e hoʻonui i ko lākou ikaika a hoʻolilo iā lākou i kūpono no nā noi he nui.Eia kekahi, ʻaʻole i hāʻule kēia mau mea paʻa i ka open-circuit, a he mea kūpono ia no nā noi e koi ana i nā ʻāpana me kahi ʻano palekana palekana.

Ma ka ʻaoʻao ʻaoʻao, ʻo ka waiwai hoʻōla ponoʻī o nā capacitors kiʻiʻoniʻoni metala ke kumu e hoʻonui ai i ka mea pohō a hāʻule ka nui o ka capacitance.Ma waho aʻe o nā waiwai hoʻōla ponoʻī, ʻo ka hapa nui o nā capacitors kiʻiʻoniʻoni metala e hāʻawi pū i ka ikaika haʻihaʻi kiʻekiʻe a me ka hana volumetric kiʻekiʻe.

No nā kikoʻī capacitor kiʻiʻoniʻoni hou aku, e ʻoluʻolu e hoʻoiho i ka catalog CRE.
