Hoʻolauna inductance

1. He nui ka reactance o ka coil o DC relay a he uuku ke au. Inā ʻōlelo ʻia ʻaʻole ia e pōʻino ke hoʻopili ʻia me ke au ʻana, e hoʻokuʻu ʻia i ka manawa kūpono. Eia naʻe, liʻiliʻi ka reactance o ka coil o ka relay AC, a he nui ke ʻano o kēia manawa. ʻO ka hoʻohui ʻana i ka DC e hōʻino i ka wili.

2. E loaʻa kahi apo pōkole pōkole ma ke kumu hao o AC contactor, akā ʻaʻole DC contactor. He lahilahi ke anawaena uwea o DC coil, no ka mea, ua like kona au me U/R, aole e loli. He mānoanoa ke anawaena uea o ka coil AC, no ka mea, he inductance ka coil, a ua loli nui ke ʻano o kēia manawa ma mua a ma hope o ka huki ʻana o ka armature. Inā paʻa ka armature a ʻaʻole e huki, e puhi ia i ka wili. Pono ke kumu hao o ka coil AC e hoʻohana i ka pepa kila silika, a hiki i ke kumu hao o DC coil ke hoʻohana i ka poloka hao holoʻokoʻa.

3. Ke hoʻololi nei ka attraction a me kēia manawa o ka electromagnet AC, ʻoi aku ka nui o nā mea ʻelua i ka hoʻomaka ʻana o ka huki, akā liʻiliʻi ma hope o ka huki. Eia nō naʻe, ʻaʻole i hoʻololi ʻia ka huki a me ke ʻano o ka DC electromagnet i ke kaʻina holoʻokoʻa o ka huki ʻana a paʻa.

4. ʻAʻole helu ʻia nā coils AC, ʻoiai ʻo DC coils i polarized ka nui. ʻO kā lākou mau loina hana i ke kumu like. Hoʻokumu lākou a pau i kahi māla magnetic i ka coil e hana i ka hana aʻe. ʻO ka ʻokoʻa, ʻo ka AC coils e hoʻopuka i kahi māla magnetic alternating, kahi i hoʻohuli nui ʻia e ka volta a me ka manawa, ʻoiai ʻoi aku ka paʻa o nā coils DC a ʻoi aku ka kiʻekiʻe o ka palekana palekana, ʻoi aku ka maikaʻi no ka hana hana koke.

ʻO ka ʻoiaʻiʻo, ʻoi aku ka kiʻekiʻe o ka inductance uea a me ka liʻiliʻi leakage inductance, a ʻoi aku ka lōʻihi o kona ola lawelawe ma mua o ka inductance maʻamau. Ke manaʻoʻiʻo nei au ua ʻike ka poʻe a pau ʻeono mahina ka manawa o ka inductance, akā pili ka wili uila uila i ke kaʻina hana a me ka mālama ʻana. Ua hala ka wili uila uea i ka lāʻau anti-oxidation a me ka hoʻāʻo ʻana i ka paʻakai ma mua o ka haʻalele ʻana i ka hale hana e hōʻoia i ka weldability maikaʻi loa o ka huahana. Hoʻopaʻa ʻia kēlā me kēia ʻeke liʻiliʻi liʻiliʻi a me ka pahu i loko a waiho ʻia me ka desiccant, no laila hiki ke hoʻonui ʻia ka manawa mālama i ʻewalu mahina. Eia kekahi, ua hoʻopaʻa ʻia ka mea ferrite ma kahi kiʻekiʻe kiʻekiʻe ma mua o 1000 degere, no laila he ikaika kiʻekiʻe a hiki ke paʻa mau loa.
