Maxay inductor-yadu sidoo kale u leeyihiin shuruudaha masaafada badbaadada?

Asalka: Iftiinka Qalabka

Shaqada aasaasiga ah ee inductance-ka ee wareegyada waa shaandhaynta, inta badan habaynta calaamadaha. Maxay u jiraan shuruudaha masaafada badbaadada marka la samaynayo shahaadada? Maqaalkani wuxuu bixin doonaa jawaabo khuseeya su'aashan.

Xaqiiqdii, wareegyada guud, ma jiraan shuruud cad oo ku saabsan masaafada badbaadada ee inductor-yada. Waxay u baahan yihiin oo keliya inay buuxiyaan shuruudaha dahaarka danabka aasaasiga ah, badeecaduna ma gaabin doonto wareegga ka dib hawlgalka muddada dheer.
Marka aan tijaabinayno inductor-yada, waxaan inta badan tijaabinaa iska caabbinta danabka ee dabaysha ilaa dabaysha ama dabaysha ilaa xudunta birlabta, badanaa qiyaastii 500VAC.

Si kastaba ha ahaatee, haddii inductor-yada lagu dabaqo xaaladaha wareegga danab-sare, way ka duwanaan doontaa. Wareegyada danab-sare, farqiga u dhexeeya biinanka inductor-ka badanaa wuxuu u baahan yahay inuu u hoggaansamo heerarka nadiifinta korantada iyo masaafada gurguurta si looga fogaado wareegyada gaaban ama sii deynta.
Sida waafaqsan heerka IEC60950, heerarka danab ee kala duwan waxay u dhigmaan masaafada ugu yar ee kala duwan. Marka wareegga danab ee 400V aan la furin, farqiga korontada ee u dhexeeya biinanka inductor-ka waa inuu ahaadaa ≥ 6.4mm.

Marka la eego masaafada wareegga, wareegyada 220V, masaafada wareegga ee substrate-ka FR4 waa inay ahaataa ≥ 4.0mm. Inductor-yada danab-sare leh, sida kuwa ku xiga transformer-ka ugu weyn ee saadka korontada beddela, masaafada dahaarka ee la xoojiyay ee ≥ 8.0mm ayaa loo baahan yahay.
Marka heerkulka shaqada ee inductor-ku uu aad u sarreeyo, masaafada badbaadada si habboon ayaa loo kordhin karaa si loogu magdhabo gabowga walxaha dahaarka leh ee ay keento isticmaalka muddada dheer ee inductor-ka.

Inta lagu guda jiro naqshadeynta wareegga, haddii masaafada wareeggu aysan ku filnayn, daloolinta ayaa sidoo kale loo isticmaali karaa in lagu daboolo shuruudaha. Xulashada agabka inductor-ka, waxaa lagama maarmaan ah in la isticmaalo qalfoofka dabka u adkaysta iyo kan dabka u adkaysta, silig dhalaalaya oo heerkul sare leh, iyo cajalad dahaareed oo ammaan ah oo la xaqiijiyay si loo hubiyo u hoggaansanaanta heerarka badbaadada iyo shuruudaha.
Guud ahaan, shuruudaha masaafada badbaadada ee inductor-yadu waa in laga hortago khataraha badbaadada ee ay keenaan burburka korontada, daadashada, iyo cilladaha dahaarka. Tani waxay tixraaci kartaa heerarka sida IEC 60950 iyo UL 60950, waxaana loo qaabeyn karaa si dhammaystiran iyadoo lagu saleynayo heerarka danabka, jawiga shaqada, iyo astaamaha agabka si loo hubiyo in tijaabada iyo shahaadada la dhammeeyo.
