Momwe Mungakonzere Ng’anjo Yolowetsamo Mwamsanga
Mng’anjo yotenthetsera yotenthetsera ndi zida zotenthetsera zosakhazikika zomwe zimagwiritsidwa ntchito m’makina opangira matenthedwe, chifukwa chake ndikofunikira kwambiri kuwonetsetsa kuti ng’anjo yotenthetsera imakonzedwanso bwino. Aliyense akuganiza kuti kutentha kwamagetsi kwamagetsi sikungawoneke kapena kukhudzidwa, ndipo kumamveka kwachinsinsi. M’malo mwake, kukonza ng’anjo yapakatikati sikovuta, chifukwa zida zonse za ng’anjo yotenthetsera ndizochepa chabe. Apa, tikufotokozera mwachidule zambiri za kukonza ng’anjo yotenthetsera, tikuyembekeza kuthandiza aliyense, chonde onetsani zosayenera.
1. Choyamba, ng’anjo yotenthetsera induction imayenera kukhazikika panthawi yogwira ntchito, ndipo thyristor, reactor, capacitor, chingwe chamadzi ozizira ndi coil induction chiyenera kukhazikika ndi madzi ozungulira. Choncho, vuto lofala kwambiri ndilokuti madzi ozizira ozizira amatha kuzizira si abwino, kuchititsa kuti kutentha kukwera, kupanga thyristor kuwotcha silicon, kuwotcha riyakitala, kutentha capacitor, ndi kuwononga wosanjikiza wa inductors.
2. Ndikoyenera kuyang’ana kayendedwe ka madzi a dera la madzi ozizira. Anthu ambiri pano ali ndi kusamvetsetsana. Iwo amaganiza kuti kuthamanga kwa madzi okwera m’madzi ozizira kumayenera kukhala ndi madzi ambiri ozizira, koma sizili choncho. Chifukwa cha kukula kwa payipi ya madzi ozizira kapena kutsekedwa kwa payipi ndi zinyalala, madzi amayenda pang’onopang’ono ndipo kuthamanga kwa madzi kumakhala kwakukulu, zomwe nthawi zambiri zimapangitsa kuti madzi azitentha kwambiri kuti asatenthe zigawozo.
3. Magawo owonongeka mosavuta a ng’anjo yotenthetsera induction ndi thyristor, capacitor, ndi chingwe chamadzi. Pakati pawo, dera lalifupi la thyristor ndilobwino kwambiri kuti muwone, koma samalani ndi kuwonongeka kofewa kwa thyristor. Kuwonongeka kofewa sikungayesedwe pamsewu. Chochitika chachikulu cha kuwonongeka kofewa kwa thyristor ndi phokoso la riyakitala, lomwe ndi lolemera kwambiri. Kuphatikiza apo, ma capacitor nthawi zambiri amakhala afupikitsa ndipo ma terminals amasweka; chipolopolocho chaphulika ndipo ndayeseranso kukonza ma capacitors, ndipo ndapeza kuti ma capacitors okonzedwa amasweka patapita nthawi yaitali. Kuwunika kwa capacitor boost kudzakhala bwino kuwona; Kulephera kwa chingwe chamadzi ndi: kuzungulira kotseguka, ndipo ndikosavuta kunyalanyaza pamene ikuwoneka kuti yasweka.
4. Pambuyo pokonza ng’anjo yotenthetsera kulephera kwa ogwira ntchito yokonza ng’anjo kufika pamalopo, ayenera kulankhulana ndi wogwira ntchitoyo kuti amvetse zomwe zalephera, musathamangire kukonza, choyamba muwone ndikuweruza malo olakwika, ngati pali mdima kapena kuwonongeka, ndipo ndiye mverani kumveka kolakwika, ndiyenonso kuyang’ana kwa chida, ndipo potsiriza mudziwe chomwe chimayambitsa kulephera. Mwachitsanzo: phokoso ntchito ya riyakitala ndi lolemera kwambiri ndi kuzimiririka. Kawirikawiri, pali vuto ndi rectifier thyristor kapena rectifier gawo; ngati phokoso la riyakitala kukuwa, nthawi zambiri vuto ndi inverter thyristor.
5. Konzani vuto la ng’anjo yotenthetsera yolowera molingana ndi njira zomwe zili pamwambapa, nthawi zambiri 75% yamavuto a ng’anjo yotenthetsera yolowera amatha kuthetsedwa.
