Pehea e ʻike ai i ka pohō dielectric o nā wili motika?

Ke ʻike nei i nā pohō dielectric i lokomotika ʻekolu paeHe mea nui nā wili no ka hōʻoia ʻana i ka hilinaʻi a me ke ola oNā mīkini uila kiʻekiʻe ACʻO kahi ʻano hana kūpono no kēia ana ʻana, ʻo ia ka hoʻohana ʻana i kahi alahaka Xilin, kahi mea hana kūikawā i hoʻolālā ʻia no ka loiloi ʻana i nā waiwai dielectric. ʻO ka waiwai tangent pohō dielectric, i kapa pinepine ʻia ʻo ka tangent pohō, hāʻawi i ka ʻike i ka maikaʻi o ka insulation o ka coil motika.

No ka hoʻomaka ʻana i ke kaʻina hana ana, hoʻohana pinepine ʻia ka pepa alumini ma ke ʻano he electrode ana. ʻO kēia koho ma muli o ka conductivity uila maikaʻi loa o ka alumini a me ka maʻalahi o ka hoʻopili ʻana. Eia nō naʻe, ʻo ka pono o ke ana ʻana e pili ana i ka hoʻopaʻa paʻa ʻana o ka pepa alumini i ka insulation coil. ʻO ka hoʻopaʻa paʻa ma waena o ka pepa alumini a me ka insulator e hoʻemi i nā hakahaka ea a hoʻonui i ka pololei o ka ʻikepili i hōʻiliʻili ʻia. Hiki i kēlā me kēia hoʻokaʻawale ke alakaʻi i nā heluhelu hewa, e hoʻopilikia ana i ka objectivity o nā hopena.

Ke hoʻopaʻa pono ʻia ka pepa alumini, hiki ke ana ʻia ka dielectric loss tangent me ka hoʻohana ʻana i kahi alahaka Xilin. Hoʻopili ke alahaka i ka volta alternating current (AC) i nā wili motika i mea e loiloi ai i nā waiwai dielectric o ka insulator. Hiki i ka ʻikepili i hana ʻia ke hāʻawi i kahi hōʻailona o ke kūlana o ka insulation, e hōʻike ana i kekahi hōʻino a i ʻole nā ​​​​kikowaena hiki ʻole ke hāʻule.

He mea koʻikoʻi ka nānā mau ʻana i ka dielectric loss tangent no ka mālama wānana. Ma ka ʻike ʻana i nā loli i nā waiwai dielectric i ka hala ʻana o ka manawa, hiki i nā hui mālama ke hana i nā hana proactive e hoʻoponopono i nā pilikia insulation ma mua o ko lākou alakaʻi ʻana i ka hāʻule ʻana o ka motika. ʻAʻole wale kēia e hoʻomaikaʻi i ka pono hana o ka motika akā e hoʻolōʻihi pū i kona ola lawelawe.

I ka pōkole, me ka hoʻohana ʻana i nā electrodes alahaka Xilin a me ka alumini foil e ʻike i ka nalowale dielectric omīkini hoʻokomo ʻekolu paeʻO nā wili he ala hilinaʻi ia e loiloi ai i ka maikaʻi o ka insulation. ʻO ka hōʻoia ʻana i kahi pilina paʻa ma waena o ka foil a me ka insulator ke kī i ka loaʻa ʻana o ka ʻikepili ana pololei a pololei, e kōkua ana i ka mālama pono ʻana i nā mīkini uila kiʻekiʻe AC.
