He kūpono no DH150-7 pilot solenoid valve coil o Doosan excavator

1. Inductance XL

ʻO ka nui o ka hopena pale o ka inductive coil i ka wā kamaʻilio i kapa ʻia ʻo inductance XL, a ʻo ka ʻāpana he ohm. ʻO kona pilina me ka inductance L a me ke alapine kamaʻilio F ʻo XL=2πfL.

2. He kumu waiwai Q

ʻO ke kumu maikaʻi Q ka nui kino e hōʻike ana i ka maikaʻi o ka coil, a ʻo Q ka ratio o ka inductive reactance XL i kona kūpaʻa like, ʻo ia hoʻi, Q = XL/R. o ka loop. ʻO ka waiwai q o ka coil e pili ana i ke kū'ē DC o ka conductor, ka poho dielectric o ka iwi iwi, ka poho i hanaʻia e ka pale a iʻole ka hao hao, ka hopena o ka hopena o kaʻili kiʻekiʻe a me nā mea'ē aʻe. ʻO ka waiwai q o ka pōʻai he ʻumi a hiki i nā haneli.

3. Puka puana

ʻO ka capacitance ma waena o ka huli ʻana o ka coil, ma waena o ka coil a me ka pale, a ma waena o ka coil a me ka pā lalo i kapa ʻia ʻo capacitance distributed. ʻO ka loaʻa ʻana o ka capacitance puʻupuʻu e hōʻemi i ka waiwai Q o ka coil a hoʻohaʻahaʻa i kona kūpaʻa, no laila ʻoi aku ka liʻiliʻi o ka capacitance puʻupuʻu o ka coil, ʻoi aku ka maikaʻi.

1. Hoʻokahi papa wili

Hoʻopili ʻia ka huila papa hoʻokahi a puni ka paipu pepa a i ʻole ka iwi bakelite me nā uwea insulated pakahi. E like me ka antenna coil ma ka lekiō transistor.

2. Honeycomb coil

Inā ʻaʻole like ka mokulele o ka pōʻai ʻeha me ka ʻili o ka ʻili, akā e hui pū me kekahi ʻano ʻike, ua kapa ʻia kēia ʻano coil. A ʻo ka helu o nā manawa e piʻo ai ka uwea i hope a i waho i ka wā e kaʻa ai i hoʻokahi manawa, ʻo ia ka mea i kapa pinepine ʻia ʻo ka helu o nā kiko pelu. ʻO nā mea maikaʻi o ka honeycomb winding method he liʻiliʻi liʻiliʻi, liʻiliʻi puʻupuʻu capacitance a me ka inductance nui. Ua ʻeha ʻia nā ʻili ʻili meli e ka mīkini wili meli. ʻOi aku ka nui o nā kiko pelu, ʻoi aku ka liʻiliʻi o ka capacitance puʻunaue.

3. Ferrite core a me ka hao pauda kumu wili

ʻO ka inductance o ka coil e pili ana inā he kumu magnetic a ʻaʻole paha. Hiki ke hoʻonui i ka inductance a hoʻomaikaʻi i ka maikaʻi o ka ferrite core i loko o ka coil hollow.

4, coil kumu keleawe

Hoʻohana nui ʻia ka copper core coil i ka unahi hawewe ultrashort. He mea maʻalahi a hiki ke hoʻololi i ka inductance ma ka hoʻololi ʻana i ka orientation o ke kumu keleawe i loko o ka coil.

5, kala kala inductor

ʻO ka inductor kala kala he inductor me ka inductance paʻa, a ua kaha ʻia kona inductance ma ke ʻano like me ke kūʻē, me ke apo kala e like me ka hōʻailona.

6, wili puʻupuʻu (choke)

ʻO ka coil e kaupalena ana i ka hele ʻana o ka uila, ua kapa ʻia ʻo choke coil, hiki ke hoʻokaʻawale ʻia i ka coil choke frequency kiʻekiʻe a me ka coil choke frequency haʻahaʻa.

7. Huli hoʻoheheʻe

ʻO ka deflection coil ka ukana o ka pae puka o ke kaapuni ʻimi TV. Pono ka deflection coil i ke kiʻekiʻe deflection sensitivity, ʻano ʻāpana magnetic, kiʻekiʻe Q waiwai, liʻiliʻi a me ke kumu kūʻai haʻahaʻa. ʻO ka ʻāpana kumu o ka lole i ulana ʻia, ua ʻāwili ʻia i loko o ke ākea, ʻelua mau kolamu pōʻai, kahi arc wili a me kahi arc sinking (a i ʻole laina hoʻonui).
