ʻO ka capacitor kiʻi polypropylene metallized no ka lako mana a me ka hoʻololi ʻana

Wehewehe Pōkole:

ʻO nā capacitors polypropylene metallized segmented kiʻekiʻe ka ʻāpana i koho ʻia no nā kānana DC hou aku, ka mālama ikehu a me nā noi like no ke kenekulia 21.

Hiʻona

1. ʻAno pahu PP, hoʻokomo ʻia ka resin maloʻo;
2. Nā alakaʻi nati keleawe / wili, ke kau ʻana o ka uhi plastik insulated, maʻalahi ke kau ʻana;
3. Ka nui o ka mana, ka liʻiliʻi;
4. Ke kū'ē i ke ana wela kiʻekiʻe, me ka ho'ōla pono'ī;
5. Ke au ripple kiʻekiʻe, ke kūpaʻa kiʻekiʻe o ka dv / dt.
E like me nā huahana CRE ʻē aʻe, loaʻa i ka capacitor series ka palapala hōʻoia UL a ua hoʻāʻo ʻia ka puhi ʻana o 100%.

Noi

1. Hoʻohana nui ʻia ma ke kaapuni DC-Link no ka kānana ʻana i ka mālama ikehu;
2. Hiki ke pani i nā capacitors electrolytic, hana maikaʻi a me ke ola lōʻihi.
3. Pv inverter, mea hoʻololi mana makani; ʻO nā ʻano mea hoʻololi alapine a pau a me ka lako mana inverter; Nā kaʻa uila maʻemaʻe a me nā kaʻa hybrid; SVG, nā polokalamu SVC a me nā ʻano hoʻokele mana ʻē aʻe.
