Me kana da yin hanyar da ke cewa mafi yin hankali a tashar hankali na transformer?

Idan da yin hanyar tashin karamin zafi ba ta yi, yana nufin kadan gaba daga cikin yanayi. Dalilin mafi yawa shine, idan ba ake amfani da shirin na biyu, tsari na farko yana da muhimmanci a wuce masu daidai. Misali, idan tsari na rike shi ne 10 kV, tsari na biyu a lokacin da ba ake amfani da shi yana iya haɗa zuwa 10.5 kV.

Wadannan tsari mai yawa yana sauyi ƙwarewa masu karamin zafi (B) a cikin take. Idan a tuna bayyana:

B = 45 × Et / S
(indaso Et shi ne volts-per-turn da aka sanya, kuma S shi ne tsakiyar cikin take), idan ake fi inganta tsari na biyu, za a iya haɗa kan Et, don haka ya zama B a iya haɗa zuwa ma'ana da suka sanya.

Ƙwarewar masu karamin zafi mai yawa yana sauyi magnetostriction da kadan kadan mai magana, wanda ke nuna a fadin kadan gaba a lokacin da ba ake amfani da shi. Wannan shine dalilin mafi yawa da ya haɗa kan fadin kadan gaba.

Dalili na biyu shine haɗa kan tsari na biyu. Idan tsari na biyu ya haɗa, bane ba suna da damar fadin kadan gaba, amma yana nuna abubuwa masu nan kamar mutumiyar ƙwarewa da kungiyoyi. Farkon silikon steel sheets na da karfin kwalliya mai yawa yana da karfin karamin zafi mai yau, wanda ke haɗa kan tsari na biyu mai yawa. Amma, idan ake amfani da ƙwarewa masu yawa ko kwalliyar daɗi (da karamin zafi mai yawa da ƙwarewar masu daɗi), za a iya haɗa kan tsari na biyu mai yawa, kuma zai iya haɗa kan fadin kadan gaba saboda ƙwarewar masu daɗi.

Abubuwa masu yawa da ke saukar fadin kadan gaba sun hada da ayyukan damping, tsawonsa cikin take, da kuma idan aikin take ke saukar mechanical resonance. Amma, wannan yana haɗa kan ayyukan fadin kadan gaba a cikin yanayi - ba a lokacin da ba ake amfani da shi da kuma a lokacin da ake amfani da shi.

Tabbataccen: Idan karamin zafi yana nuna fadin kadan gaba mai yawa a lokacin da ba ake amfani da shi, yana nuna cewa ƙwarewa an samu. A lokutan da ba ake amfani da shi, duba idan tsari na biyu na 12 V shi ne sama. Idan ba su sama, zai iya dole ƙwarewar da suka sanya da suka sanya ƙwarewan sama.

Kuma, a lokacin da ake duba tsari na resistor Rs, idan shape-nya ta nuna peak overshoot, ba sawtooth rise ba, yana nuna cewa ƙwarewar 12 V yana buƙatar turns masu yawa.

Idan ba a zama daidai a dole ƙwarewar, yanayin da ake iya yi shine a haɗa kan resistance na R_L a kan yawan 5 kHz (tabbataccen: likitoci a cikin rubutun - yana da kyau a zama kHz, ba Hz ba). Wannan ɗaukan yana haɗa kan yawan daidai ga duk ƙwarewar, amma ba zai iya haɗa kan abubuwa masu yin kamar analog clocks.

Don haɗa kan aiki da kudin, wannan takamfa shi ne ake cire voltage regulator; saboda haka, tsari na faru yana daza a lokacin da battery voltage yana daza.

Amsa aiki na prototype:

• Maximum efficiency: 94%

• Output voltage: slightly lower than the target 230 VAC, but aligns well with China’s standard nominal output of 220 VAC.

Don in samu 230 VAC output daga 13 VDC input, either:

• Increase the turns ratio (secondary-to-primary) of the transformer, or

• Replace it with a transformer rated for 230 V secondary and 11 V primary.
