ʻO nā kānana a me nā capacitors DC-link nā mea nui passive no ka ʻōnaehana hoʻololi mana

ʻO nā kānana a me nā capacitors DC-link nā ʻāpana passive kī no ka ʻōnaehana hoʻololi mana

ʻO ka wehewehe pōkole:

ʻO nā capacitors polypropylene metallized kiʻekiʻe i hoʻokaʻawale ʻia ka mea koho no nā kānana DC he nui, mālama ikehu a me nā noi like no ke kenekulia 21.

1. PP Box-type, infusion resin maloʻo;
2. Ke alakaʻi nati keleawe / wili, hoʻonoho ʻia ka uhi plastik insulated, hoʻokomo maʻalahi;
3. Ka mana nui, ka liʻiliʻi;
4. Ke kū'ē i ka volta kiʻekiʻe, me ka ho'ōla pono'ī;
5. Kiʻekiʻe ripple o kēia manawa, kiʻekiʻe dv / dt hiki ke kū.
E like me nā huahana CRE ʻē aʻe, ua loaʻa i ka capacitor series ka palapala UL a me ka 100% burn-in hoʻāʻo ʻia.

Palapala noi

1. Hoʻohana nui ʻia ma DC-Link kaapuni no ke kānana ʻana i ka mālama ʻana i ka ikehu;
2. Hiki ke pani i nā capacitors electrolytic, ʻoi aku ka maikaʻi o ka hana a me ke ola lōʻihi.
3. Pv inverter, makani mana converter;ʻO kēlā me kēia ʻano o ka hoʻololi alapine a me ka hāʻawi mana inverter;Ka uila maʻemaʻe a me nā kaʻa hybrid;SVG, SVC mea hana a me nā ʻano o ka mana maikaʻi o ka mana.

ʻO ke koi no ka mālama ʻana i ka ikehu a me nā kumu hou e koi ai i ka hoʻomohala ʻana i nā huahana e like me nā kaʻa uila, nā mea hoʻololi PV, nā mea hana makani.Pono kēia mau huahana i ka DC i AC inverter e hoʻomaopopo i ka ʻōnaehana hana.ʻO nā kānana a me nā capacitors DC-link nā mea nui passive no ka ʻōnaehana mana e hāʻawi me ke kākoʻo i ka pono o ka hoʻonui ʻana i ka mana me nā kaha kiʻekiʻe a me nā au ripple.

Ma ke ʻano he ʻoihana ʻenehana kiʻekiʻe e kū mai ana, he hui R&D mua a me ka hui hana ʻo CRE no nā capacitors kiʻiʻoniʻoni uila, a ua hoʻokumu i nā kikowaena ʻenehana R&D mana me nā keʻena noiʻi kaulana honua.I kēia manawa, ʻoi aku ka nui o ka CRE ma mua o 40 mau mea hana a me nā palapala hoʻohālike ponoʻī a ua komo i ka hoʻomohala ʻana i nā kūlana aupuni a me nā ʻoihana 10, i hōʻoia ʻia me ISO-9001, IATF16949, ISO14001/45001, a me UL.Hoʻolaʻa mākou e hoʻomohala i nā hoa ʻoihana hou aku no ka hoʻokele ʻana i ka mana hou.

Nā huahana kaulana ʻo CRE:
① DC-link capacitor
② Kāpena kānana AC
③ Waihona ikehu / Pulse capacitor
④ IGBT snubber
⑤ ʻO ka capacitor resonance
⑥ Ka mana hoʻoheheʻe wai
