He aha ka CBB Capacitor?
Ka hua'ōlelo "CBB capacitor"ʻike nui ʻia ma ka ʻoihana, akā naʻe, ʻo kāna hui inoa inoa e hoʻāla pinepine i nā nīnau. capacitor, ʻo ka "B" mua ke kū nei i kahi kiʻiʻoniʻoni non-polar, a ʻo ka lua "B" e kuhikuhi pono ana. polypropylene e like me ka mea dielectric. No laila, a CBB capacitor ʻo ka mea nui he non-inductive capacitor kiʻiʻoniʻoni polypropylene metala.
ʻAʻole like me nā capacitors electrolytic e hoʻohana ana i kahi electrolyte wai a loaʻa ka polarity, ka CBB capacitor he polar ole. 'O ia ho'i, hiki ke ho'ohui 'ia ma a circiit me ka nānā ʻole i nā hopena maikaʻi a maikaʻi ʻole paha, e kūpono ana ia no AC nā noi. I loko o ka ʻilika a alumini paha, e ʻike ʻoe i ʻelua ʻāpana lōʻihi loa kiʻiʻoniʻoni polypropylene metala eha paa. ʻO ka "metalization" e pili ana i kahi papa microscopic o ka alumini a i ʻole ka zinc vacuum-i waiho pololei ʻia ma luna o ke kiʻiʻoniʻoni. Hāʻawi kēia kūkulu ʻana pono ho'ōla: inā he haʻihaʻi ma muli o overvoltage, ʻo ka papa metala a puni ka hewa e hana i kahi hana like fuse liʻiliʻi, e hoʻoheheʻe a hoʻokaʻawale i ka hemahema, e ʻae i ka capacitor e hoʻomau i ka hana.
ʻO ka ʻepekema i loko: No ke aha e hoʻohana ai i ka Polypropylene Film e like me ka Dielectric?
ʻO ka puʻuwai o kekahi capacitor kona dielectric-ʻAʻole mea hoʻokaʻawale e noho ana ma waena o ka ʻelua papa. ^. Ke koho o dielectric kauoha i ka ka capacitor ʻano hana. ʻEnekinia e hoʻohana i ke kiʻi polypropylene no ka mea, hāʻawi ia i kahi ʻokoʻa o nā pono ma mua o nā mea ʻē aʻe e like me polyester (CL capacitors).
ʻO ke kiʻiʻoniʻoni polypropylene e like me ka dielectric ʻike ʻia e ka loa dielectric haʻahaʻa poho a me ka piʻi iki o ka wela o loko. Ke alakaʻi nei kēia i kahi nui loa haʻahaʻa dissipation kumu (DF), emi pinepine ma mua o 0.001 ma 1 kHz.

Nā Kūlana Palekana: ʻO ke kuleana koʻikoʻi o ka X2 Capacitor
ʻO ka palekana ka mea nui mea uila hou. ^. 'Ōlelo X2 capacitor ʻo ia kahi mana palekana i helu ʻia o ka CBB capacitor. Hoʻolālā ʻia kēia mau mea e hoʻopili pololei ʻia ma waena o ka laina nui AC (Line-to-Line). ʻO kā lākou kuleana nui hoʻopili electromagnetic (EMI) kaohi ana.
No ke aha he mea nui ka helu "X2"? Inā he maʻamau capacitor ʻAʻole hiki ke hoʻopili ʻia i nā kumu nui, hiki ke kaʻapuni pōkole a hoʻomaka i ke ahi. ʻO An X2 capacitor, akā, ua hoʻolālā ʻia e hāʻule "palekana" - maʻamau ma kahi ākea circiit mode—a hiki ke pale i ka nui overvoltage spikes (hiki i ka 2.5kV) me ka ʻole o ke ahi. Hoʻohana lākou i kahi loea kūikawā kiʻiʻoniʻoni polypropylene metala a ua hoʻopaʻa ʻia i loko o kahi hoʻāʻo ikaika ʻili ʻili a epoxy resin. ʻO kēlā me kēia lako mana, mai kāu charger laptop a hiki i ka ʻoihana lako mana, hilinai ma X2 capacitors i kānana mai ka walaʻau ʻana a mālama pono i ka hāmeʻa me nā lula palekana honua.
Ma waho aʻe o nā kumu: CBB82 a me nā noi kiʻekiʻe o kēia manawa
ʻOiai ka liʻiliʻi ma mua o ka CBB22 a i ʻole CBB81, ʻo ka CBB82 hōʻike i kahi hoʻololi hou no nā pono kikoʻī.
