He aha i hiahiatia ai hoki ngā whakaritenga tawhiti haumaru mō ngā inductors?

Taketake: Te Mārama o ngā Pūrere

Ko te mahi matua o te inductance i roto i ngā ara iahiko ko te tātari, ko te nuinga mō te tukatuka tohu. He aha ngā whakaritenga mō te tawhiti haumaru i te wā e mahi ana i te tiwhikete? Ma tēnei tuhinga e whakarato ngā whakautu e tika ana ki tēnei pātai.

Ina hoki, mō ngā ara iahiko whānui, kāore he whakaritenga mārama mō te tawhiti haumaru o ngā inductors. Me tutuki noa i a rātou ngā whakaritenga matua mō te whakamarumaru ngaohiko, ā, e kore te hua e poto te ara iahiko i muri i te whakamahinga roa.
I te whakamātautau i ngā inductors, he maha ngā wā ka whakamatautauria e mātou te ātete ngaohiko o ngā takai ki ngā takai, ngā takai rānei ki ngā matua aukume, tata ki te 500VAC.

Heoi, ki te whakamahia ngā inductors i roto i ngā āhuatanga ara iahiko ngaohiko-tiketike, ka rerekē. I roto i ngā ara iahiko ngaohiko-tiketike, me tutuki te mokowā i waenga i ngā pine inductor ki ngā paerewa ātea hiko me te tawhiti ngoki hei karo i ngā ara iahiko poto, i ngā tukunga rānei.
E ai ki te paerewa IEC60950, ko ngā taumata ngaohiko rerekē e rite ana ki ngā tawhiti iti rawa rerekē. Ina kore he kōhao mō te ara iahiko ngaohiko 400V, me ≥ 6.4mm te āputa hiko i waenga i ngā pine inductor.

Mō te tawhiti ngoki, mō ngā ara iahiko 220V, me ≥ 4.0mm te tawhiti ngoki o te papa FR4. Mō ngā inductors ngaohiko-tiketike, pērā i ērā e tata ana ki te whakawhiti matua o te pūtake hiko whakawhiti, me ≥ 8.0mm te tawhiti whakakaha o te whakamarumaru.
Ina teitei rawa te pāmahana mahi o te inductor, ka taea te whakanui ake i te tawhiti haumaru hei utu mō te koroheketanga o te rauemi whakamarumaru i puta mai i te whakamahinga roa o te inductor.

I roto i te tukanga hoahoa ara iahiko, ki te kore e ranea te tawhiti ngoki, ka taea hoki te whakamahi i te mokowā hei whakatutuki i ngā whakaritenga. Mō te kōwhiringa o ngā rauemi inductor, me whakamahi he anga ātete ahi me te ātete mura, he waea enamel ātete pāmahana teitei, me te rīpene whakamarumaru whaimana haumaru hei whakarite kia tutukihia ngā paerewa me ngā whakaritenga haumaru.
I te nuinga o te wā, ko te tawhiti haumaru mō ngā inductors he ārai i ngā tūponotanga haumaru e puta mai ana i te pakaru hiko, te turuturu, me te rahunga o te whakamarumaru. Ka taea tēnei te pā ki ngā paerewa pēnei i te IEC 60950 me te UL 60950, ā, me hoahoa whānui i runga i ngā taumata ngaohiko, ngā taiao mahi, me ngā āhuatanga rauemi kia pai ai te whakamātautau me te tiwhikete.
