Sei ma inductors ainewo zvinodiwa zvekuchengetedza kure?

Yepakutanga: Chiedza cheMidziyo

Basa guru re inductance mumasekete nderekusefa, kunyanya pakugadzirisa masaini. Sei paine zvinodiwa zvekuchengetedza daro pakuita chitupa? Chinyorwa chino chichapa mhinduro dzakakodzera kumubvunzo uyu.

Kutaura zvazviri, kune macircuit akajairika, hapana chinodiwa chakajeka chekuti ma inductors agare kure zvakachengeteka. Anongoda chete kusangana nezvinodiwa zvekudzivirira magetsi, uye chigadzirwa hachizopfupi mushure mekushanda kwenguva refu.
Patinenge tichiyedza ma inductors, tinowanzo kuyedza kuramba kwemagetsi kwema windings kana ma windings kune magnetic cores, kazhinji kacho anenge 500VAC.

Zvisinei, kana ma inductor akashandiswa mu high-voltage circuit, zvichave zvakasiyana. Mu high-voltage circuits, nzvimbo iri pakati pe inductor pins inowanzo fanirwa kutevedzera mitemo yekubvisa magetsi uye creepage distance kudzivirira short circuits kana discharges.
Zvichienderana neIEC60950 standard, mazinga akasiyana emagetsi anoenderana nedaro diki rakasiyana. Kana circuit yemagetsi ye400V isina kuvharwa, mukaha wemagetsi uri pakati pemapini einductor unofanirwa kuva ≥ 6.4mm.

Panyaya yedaro rekutsvedza, pamaseketi e220V, daro rekutsvedza reFR4 substrate rinofanira kuva ≥ 4.0mm. Kune ma inductor ane voltage yakawanda, akadai seaya ari pedyo ne transformer huru ye switching power supply, daro rekutsvedza rakasimbiswa re ≥ 8.0mm rinodiwa.
Kana tembiricha yekushanda yeinductor yakakwira, daro rekuchengetedza rinogona kuwedzerwa zvakakodzera kuti ritsive kukwegura kwechinhu chinodzivirira kunokonzerwa nekushandiswa kwenguva refu kweinductor.

Mukugadzirwa kwedunhu, kana daro rekufamba risina kukwana, slotting inogonawo kushandiswa kusangana nezvinodiwa. Pakusarudza zvinhu zve inductor, zvakakosha kushandisa skeleton isingatsvi uye inodzivirira moto, waya ye enamel inodziya zvakanyanya, uye tepi yekudziya ine chitupa chekuchengetedza kuti ive nechokwadi chekutevedzera mitemo yekuchengetedza nezvinodiwa.
Kazhinji, chinodiwa chekuchengetedza ma inductors ndechekudzivirira njodzi dzekuchengetedza dzinokonzerwa nekuputsika kwemagetsi, kubuda kwemvura, uye kutadza kupinza magetsi. Izvi zvinogona kureva zviyero zvakaita seIEC 60950 neUL 60950, uye zvinogadzirwa zvakakwana zvichienderana nemazinga emagetsi, nzvimbo dzekushanda, uye hunhu hwezvinhu kuti ive nechokwadi chekuti kuyedzwa uye chitupa zvabvumidzwa.
